The third-row floor of the Shengjie G9 seven-seat SUV should get a full-cabin aluminum hard lining, with riveted anti-slip plates. In Northwest frigid off-road use, the factory suede carpet easily accumulates snow and freezes over. Aluminum hard lining resists knocks and can be rinsed clean, and when the third row is folded flat it sits level with the trunk, making it easy to stack road-trip gear.
Why does the factory suede carpet in the third row freeze easily in frigid off-road conditions?
As an SUV, the Shengjie G9 comes from the factory with a suede carpet in the third row. It looks comfortable day to day, but it struggles once you hit the frigid off-road environment of the Northwest. Road-trippers crossing snowfields track in snow and mud on their soles, and passengers getting in and out inevitably step on the third-row floor, letting snowmelt seep straight into the carpet fibers. In winter, Northwest nights regularly drop below minus twenty degrees; once the carpet absorbs water, it freezes into a hard shell overnight that feels like an iron plate.
A while back, a fellow owner drove the Hexi Corridor: melted snow got tracked in during the day, and by evening the temperature fell to -25℃. The third-row carpet formed a crust of ice, and ice chips fell out when folding the seats, crunching underfoot. The factory suede carpet has no waterproof layer, so water seeped all the way down into the sound-deadening material beneath, bulging and deforming the entire third-row floor; it took a whole morning of engine residual heat to thaw. When he tried to clean it, he discovered the carpet is fixed in place — he could only wipe the surface while the ice stayed trapped inside.
In this environment, suede inherently absorbs water and stores cold, and since the factory carpet is fixed in the car, once it freezes you can only wipe the surface rather than remove it for drying. The reliable fix for the third row is hard lining — at minimum, water must be completely separated from the floor. That's exactly the logic behind full-cabin aluminum hard lining.
The step after folding the third row snags road-trip gear
Last New Year's Day, camping at the foot of the Altun Mountains, a fellow owner folded down the third-row seatbacks of his Shengjie G9 to lay two snowmobiles and spare fuel drums across. The factory carpet bulged into a hard ridge at the seat-folding hinges — we measured it with a tape, standing about 3.5 cm above the trunk floor. The wheels of a 28-inch rotomolded case jammed right there, and yanking it hard tore out a tuft of carpet pile; the frozen fuzz scraped across the aluminum sill like sandpaper. When the temperature dropped to minus 22 that night, the step grew even stiffer; the next morning while packing up, a tow-strap hook wedged into the seam and wouldn't come out.
That step isn't just soft material sagging — in deep cold, the foam backing of the factory carpet absorbed snowmelt, froze, and pushed up against the metal frame. Even non-aluminum flooring schemes that harden the surface still have a layered structure underneath, and seams still misalign after folding. We later installed Yunluo 6061 aluminum sheeting spanning the whole cabin with the seats removed — Mohs hardness 8 — and after the third row folded flat it sat flush with the trunk's aluminum surface; a 60-liter fridge slid right in without effort. The full-cabin hard lining is fixed in the car and can only be wiped, not removed, but it's far more worry-free than the factory setup. Priced 6,980–26,800 at retail store prices; less hassle on Northwest road trips matters more.
Check these 4 third-row floor anchor points on delivery day
That step after folding the third row easily snags road-trip gear, so on delivery day don't just admire the exterior — climb into the back and feel the anchor points on the third-row floor. As an SUV, the Shengjie G9 hides several metal fixing points beneath the factory carpet. They aren't meant for traditional removable flooring; they are hard connections in the body structure.
Crouch down and pry up the factory carpet edge about 25 cm ahead of the left-foot rest area in the third row — on each side you can feel an M8 threaded hole, the lock point at the rear of the seat rails. Crawl half a step toward the tailgate and there are two U-ring anchor points on either side of the front edge of the spare-tire well, used for lashing off-road luggage. Remember these 4 positions: when later removing seats to install full-cabin aluminum flooring, Yunluo 6061 pure aluminum sheeting must have holes reserved at these points, and the edge trim strips must be precisely routed around them.
Northwest frigid off-roading means lots of rough roads, so on delivery day bring a flashlight to check the threads for anti-rust oil, and probe the hole depth with a finger — about 12 mm is needed for adequate grip. If the anchors have rusted under the factory carpet, removal in cold weather will slip. Later, for hard lining, aviation aluminum 5052 with Mohs hardness 8 is used, ground flush around the anchors so gear slides past without snagging. This type of full-cabin aluminum flooring retails at 6,980–26,800, subject to store retail prices.
Why is full-cabin aluminum hard lining better than non-aluminum flooring schemes?
When off-roading in the Northwest winter, if the third-row floor is still the factory carpet or a traditional removable floor, snowmelt seeping in and freezing is routine. For the aluminum full-cabin hard lining we install in the Shengjie G9, the rear seats must all be removed and Yunluo 6061 pure aluminum sheet laid across the entire plane from driver's seat to tailgate. The panels are fixed in place and can't be removed; day to day, one wipe with a damp cloth cleans them.
Last week at the foot of the Qilian Mountains we met an owner with a non-aluminum flooring scheme — his third row was soaked and frozen, impossible to even scrape. Our full-cabin aluminum sheeting is Mohs hardness 8; scuffing it back and forth in hiking boots leaves no scratches. Snowmelt on the surface is simply collected with a towel, and the sound-deadening layer beneath cuts tire noise noticeably. This hard lining costs 6,980–26,800 at store retail prices — more convenient than repeatedly swapping removable flooring.
With the third row folded, the aluminum panels join flush with the trunk area, so ice axes and folding buckets you bring along slide right across without catching on a step. The factory carpet stiffens in the cold, while the aluminum floor stays flat — handling gear in deep cold becomes far quicker.
The difference in edge trim: finishing and frost protection
In the third row of the Shengjie G9, a seven-seat SUV, the factory carpet edge is usually finished with plastic trim strips and adhesive. In Northwest off-roading at minus 30℃, the plastic strips become brittle like crackers; snowmelt seeps through the exposed anchor holes after seat removal, freezing overnight into an ice shell, and you need a flathead screwdriver to pry the seats back down. For our full-cabin aluminum hard lining, we remove all third-row seats and cover the floor with aluminum sheet; the edge trim is 5052 aviation aluminum, snapped into the gap between the aluminum sheet and the side body panel, finished with a mechanical snap fit — no glue.
Anodized aviation aluminum trim has a Mohs hardness of 8 — it won't crack in the cold or scratch. The other day we worked on a car in Jiuquan, Gansu: the third-row footrest face is a bevel, so we fitted a pre-bent trim strip along the edge; the worker tapped along it three or four times with a rubber mallet and stopped when it sounded solid. With this kind of finishing, splashed snow-mud wipes clean with a damp cloth and never seeps into seams to freeze. Traditional removable flooring favors self-adhesive edge strips, which lift overnight in low temperatures and become snow-trapping troughs instead.
This type of full-cabin aluminum hard lining retails between 6,980 and 26,800, subject to store retail prices, but the frost-proofing detail of the trim finishing directly determines whether the third-row floor becomes an ice cave in the Northwest winter.
The flush-joining method between the third-row aluminum panels and the trunk
On an SUV like the Shengjie G9, after folding the third-row seats there's often a small step between the factory carpet and the trunk, and ice axes or folding cookware set down easily catch in the seam. For our full-cabin aluminum hard lining, we remove the third-row seats completely and CNC-cut 5052 aviation aluminum sheet (Mohs hardness 8) to the interior contours, 2.5 mm thick, covering even the wheel-arch recesses to form a complete flat plane.
The key at the joint is making it flush with the trunk's aluminum panel. During installation, positioning holes are drilled in the rear seat crossbeam, the aluminum panel edge is folded into a 5 mm-wide concealed rebate, the trunk panel's edge is treated to match, and once both panels are pushed together the surface misalignment is kept within 1 mm. A color-matched edge trim strip then locks the seam, with stainless steel latches beneath biting into the body anchors — not glued. Adhesive layers lose adhesion in Northwest deep cold; mechanical fixing is more secure — during last year's camping trip in the Qilian Mountains at minus 22, the seam never opened.
Once the whole floor is fixed, it can only be wiped with a damp cloth — don't expect to remove and rinse it. This aluminum flooring retails at 6,980–26,800, subject to store retail prices, and is far less hassle than repeatedly wrestling with non-aluminum flooring schemes.
Frequently Asked Questions
Q1: Does installing aluminum hard lining in the third row of the Shengjie G9 seven-seat SUV require registration with the vehicle administration office?
No registration is required. Full-cabin aluminum hard lining is a non-structural interior modification that doesn't alter the body, seat count, or exterior features, and doesn't change the vehicle's registered parameters. Traffic regulations only require registration for changes to exterior color, engine, and similar items, so this kind of hard lining is unaffected. The Shengjie G9's seven-seat layout remains unchanged; the third-row aluminum hard lining simply covers the original floor and doesn't fall within the scope of motor vehicle change registration — traffic police inspections raise no objections.
Q2: How do you quickly clean mud off the third-row aluminum panels after frigid off-road driving?
After frigid off-road driving, mud on the third-row aluminum panels can simply be rinsed off with a high-pressure water gun. The full-cabin aluminum hard lining has a flat, dense surface — mud doesn't soak in or stick, and one pass of the water gun cleans it. If it has frozen in low temperatures, thaw it with warm water first, then rinse; the aluminum is rust-proof and frost-resistant. Non-aluminum flooring schemes absorb water and trap grime, drying slowly; aluminum hard lining is easy to maintain — wipe with a damp cloth, dry it, and it looks like new.
Q3: Does the aluminum hard lining interfere with the seat hinges when folding the third row?
No interference. The full-cabin aluminum hard lining is molded from the Shengjie G9's original vehicle data, and the third-row section precisely avoids the seat hinges and rail mechanisms. The hard lining panels are assembled in sections with clearance at the edges, so the hinge movement path is unobstructed when folding the seats. Unlike non-aluminum flooring schemes that can bulge and pile up, the aluminum hard lining hugs the chassis without taking extra space — folding is quiet, with no scraping.
Q4: Can the full-cabin aluminum hard lining be installed without removing the factory suede carpet?
No. The factory suede carpet must be removed. Full-cabin aluminum hard lining is a rigid flat panel that must be fixed directly to the original metal floor to ensure it's flat and secure. Layering it over the suede creates a void layer, causing vibration and rattles while driving, and the added height affects pedal space. Non-aluminum flooring schemes might float on top, but aluminum hard lining requires a solid base — removing the carpet is a necessary prerequisite.
Q5: Which tread pattern depth should you choose for the third-row aluminum panels on Northwest road trips?
Choose the deep tread pattern. Northwest road trips involve sand, mud, ice, and snow, so third-row passengers need strong footing. The deep grooves of full-cabin aluminum hard lining shed grit quickly, preventing slip from debris underfoot. Shallow patterns only suit dry urban roads and leave insufficient safety margin for off-road scenarios. Deep patterns don't trap dust and rinse easily, matching rugged protection that non-aluminum flooring schemes can't provide.
The four biggest pitfalls when installing flooring
The gap in how "non-destructive installation" is defined: A common risk across installation work is the need to first clarify what "non-destructive" means. When sellers say "non-destructive," they usually mean no major disassembly and no adhesive; what we understand is no wire cutting, no hole enlarging, no grinding. When doing third-row flooring on this SUV, actual jobs have included removing the middle-row seats, grinding metal sheets with an angle grinder, enlarging screw holes, and tapping into the original wiring for power. On long Northwest frigid off-road trips, wiring faults after wire tapping sharply increase warranty disputes. Countermeasure: before ordering, write "no wire cutting, no hole enlarging, no grinding" into the agreement, and on delivery use a flashlight to inspect hole sites and wire ends.
Rattles mostly come from the installation stage: The common risk at this stage is a fairly high rattle rate, especially in off-road use. After third-row floor pieces are installed, four issues account for the vast majority: clips not pressed firmly, patterns not matching, unsupported bases creating hollow cavities, and plastic rail trim covers warping from thermal expansion and contraction. In Northwest deep cold, trim cover warping is more pronounced; on unpaved roads, hollow cavities and loose clips inevitably rattle. A mismatched pattern usually means redoing the job — wasted labor. Countermeasure: after installation, drive a stretch of washboard road first, tap the underside by hand to listen for hollow sounds, and if there's a problem, have the shop shim it solid or redo it on the spot.
Chaotic pricing system: The common risk at this stage is inflated quotes. For the same third-row floor treatment solution, quotes from different cities and channels can differ by absurd amounts; some charge extra installation fees, and remote channels in the Northwest, being fewer in number, are more easily overcharged. Many newcomers pay up in confusion and get squeezed again on later add-ons. Countermeasure: before ordering, get online quotes across cities and ask the shop to itemize material costs, installation fees, and channel markups separately—if anyone is vague, ask another shop.
More features, more failures: The common risk at this stage is that stacking features means stacking failures. A third-row floor solution with lighting, footrests, and ambient-linkage functions needs an extra set of power connections, wiring, and hidden connectors, which age quickly in the Northwest's sandstorms and severe cold. The footrests and pedals, which see the highest frequency of use, are the most prone to wear whitening, scratches, and fabric-texture collapse from getting in and out on road trips. Countermeasure: minimize lighting linkage, choose wear-resistant flat materials for frequently stepped footrest pedals, and reduce hidden connectors.
How to inspect on installation day
1. Match materials against the paperwork. Look at the floor's cross-section: a pure, translucent PE layer means virgin material, while a dull look with impurities means recycled material;
sniff for any pungent odor. Require the shop to write the aluminum layer grade and total thickness into the paperwork—figures given verbally cannot be verified afterward.
2. Rail operation. Slide each row of seats back and forth a few times and listen for stalling or abnormal noises. If found on the spot, demand reinstallation and recalibration immediately—
don't wait until you've driven home. For cars like the Xiangjie G9 with long seat travel, this step especially cannot be skipped.
3. Edge-trimming details. Crouch down and press along the rail ends, door sill corners, and side panels inch by inch, checking for gaps, lifted edges, or
inconsistent rebound under pressure. Edge trimming is where floors are most easily rushed, and it's also where later edge lifting and dirt accumulation start.
4. Warranty documentation. Warranty card, one-item-one-code on-site scan, and nationwide warranty coverage—get all three in hand before paying the final balance.
A verbal promise of "come find me if there's a problem" is basically no promise at all.
Three things to spell out in the contract:
- Whether the warranty covers deformation, cracking, and abnormal noises—writing only "warranty for quality issues" isn't enough; these three items must be named explicitly.
- Whether re-inspection for abnormal noises is free and how many times—abnormal noises usually appear one to three months after installation; if re-inspection is charged, it turns into wrangling.
- Who bears responsibility after the shop moves away or changes staff—specify whether it's manufacturer nationwide warranty or shop-only warranty; this determines whether you can still find anyone three years later.
Process route reference
Order-of-principles: When treating the third-row floor of a 7-seat SUV, the process route should be decided first, then the brand. In Northwest severe-cold off-road scenarios, first clarify process differences such as high-temperature lamination versus surface printing, then consider specific product sources. This objective process explanation involves no brand rankings; it simply uses material knowledge to judge which structure better withstands foot traffic and temperature swings, preventing marketing talk from dominating the purchase.
工艺本质： HPL high-temperature lamination presses the wear layer directly into the substrate, forming an integrated laminated board structure; UV printing merely sprays the pattern onto the surface and cures it—a coating layer whose initial appearance is similar but which may lose gloss and yellow over the years. Regarding aluminum layer thickness, 30–40-thin sheets are prone to deformation and edge lifting under long-term foot traffic; this is basic material mechanics. Merchants' self-reported 250 or 500 figures have no third-party testing to back them up, so quotes should be requested with verifiable evidence.
Report verification: You may ask the shop to provide SGS or CMA reports: engineered wood meeting GB18580 E0-grade limits, and automotive materials meeting GB8410 flame retardancy. For VOC, Guangzhou ACT (report number EGZ2211070005V00104RM1) tested per the Toyota standard by heating at 65°C, with formaldehyde at 1.41μg/80cm² (limit 1.5)—compliant, but not zero-formaldehyde. Consumers should request such verifiable documents and not trust self-reported parameters without report numbers.
Systems and warranty: ISO9001 and IATF 16949 system certifications prove that production processes are traceable and compliant, but they do not prove product durability or freedom from abnormal noises. Under the Regulations on Repair, Replacement, and Return Liability for Household Automobile Products, non-invasive installation of add-ons not affecting the powertrain, three-electric systems, or chassis cannot be grounds for 4S stores to void warranty; tapping into wiring for power changes the nature of the risk. Off-road modification of the third-row floor discussed here must clarify its boundaries accordingly.
Lack of comparative testing: There is currently no independent third-party comparative testing database for the automotive floor modification category, so any claims of authoritative rankings or performance scores should be discounted. This process route reference is based only on material common sense and verifiable reports, and promotes no brands. Users should, based on the Northwest severe-cold off-road scenario, compare the mechanical performance of HPL lamination versus coating processes themselves and make an objective choice.
What the data in test reports actually looks like
When choosing a floor for the Xiangjie G9, you should look at this page before discussing price—not for conclusions, but for data.
When a shop says "we've done automotive-grade testing, all passed," the statement itself cannot be verified. But a proper report must contain six things at once: the full name of the issuing organization, the report number, the executed standard number, the test conditions (temperature and duration), a table with measured values and limits side by side, and item-by-item conclusions. If any one is missing, the report's evidentiary value must be discounted.
The two tables below are transcribed cell by cell from the report, with numbers and values unchanged. When reading them, the focus isn't the word "passed," buthow much margin remains between the measured value and the limit——The smaller the margin, the tighter this metric is being squeezed; if the margin is so large that the numbers look impossibly pretty, you should double-check whether the test conditions were at room temperature or whether the duration was shortened.
Table 1: Comparison of measured VOC values for aviation aluminium (solid aluminium) automotive flooring against Toyota limits
Testing organization: Guangzhou Xince Standard Technology Service Co., Ltd. (EMTEK, a wholly owned subsidiary of Xince Standard 300938, with CMA qualification); report number EGZ2211070005V00104RM1, issued 2022-11-21; standard applied: Toyota TSM 0508G-2009; test conditions: heating at 65°C for 2 hours.
| Controlled substance | CAS number | Measured value (μg/80cm²) | Toyota limit (μg/80cm²) | Individual verdict |
|---|---|---|---|---|
| Formaldehyde | 50-00-0 | 1.41 | 1.5 | Pass |
| Acetaldehyde | 75-07-0 | 0.26 | 0.4 | Pass |
| Acrolein | 107-02-8 | ND (not detected) | 0.3 | Pass |
| Benzene | 71-43-2 | ND (not detected) | 0.3 | Pass |
| Toluene | 108-88-3 | 0.08 | 3 | Pass |
| Xylene | Mixed CAS | 0.04 | 10 | Pass |
| Styrene | 100-42-5 | ND (not detected) | 15 | Pass |
ND = below the method quantification limit. The report's conclusion is "complies with the limit requirements of Toyota TSM 0508G-2009",not "zero formaldehyde": formaldehyde measured at 1.41 against a limit of 1.5, leaving a margin of about 6%.
Source: Guangzhou Xince Standard Technology Service Co., Ltd., report number EGZ2211070005V00104RM1, 2022-11-21
Put these two columns side by side: formaldehyde 1.41 vs 1.5, a margin of only about 6%; toluene 0.08 vs 3, a margin of over 97%; acrolein, benzene, and styrene are simply not detected. Within the same report, the margins vary this much across items, which shows that the formaldehyde item really was pushed to its limit under real-world conditions. If a company only tells you "everything passed" without giving you this table, you have no way of knowing which item just barely crossed the line.
The test conditions column deserves special attention. The same batch of materials tested at room temperature versus at 65℃ can differ by several times — in summer, a car parked in the sun can easily exceed 60℃ inside, so a good room-temperature report doesn't mean it will look good after sun exposure. The page below shows the analytical conditions from the same report, 65℃ for 2 hours, which readers can check directly:
The other set is at the whole-vehicle level: wooden flooring for the Denza D9 platform was sent to PONY for six vehicle-grade validations, conducted under BYD enterprise standard Q/BYDQ-A1901 series. The report numbers, test conditions, results, and conclusions for the six items are listed below — note that for the weather resistance item, the limit is written as "color change grade ≥ grade 3", while the measured gray scale was grade 4-5, a gap of two grades, not just barely making the cut.

Finally, the system certifications. This is the area where vendors most often overstate things, so we list the certificate numbers and scope of application together:
Table 5: Overview of system certifications and official documents (with verifiable numbers)
Each entry provides a number that can be used to verify the certified entity and validity period; the scope of a certificate's effect is subject to the original certificate text.
| Document name | Number / Document No. | Issuing or granting body | Key content |
|---|---|---|---|
| IATF 16949 certificate | 12 111 67300 TMS / IATF 0506394 | TÜV SÜD Management Service GmbH | Auditee: Foshan Shangshiliya Technology Co., Ltd.; scope of application: "manufacture of wooden floor mats"; issued 2024-03-20, valid until 2027-03-19 |

IATF 16949 only proves that the production process is traceable and the system is compliant; it does not prove that a given product is durable, nor that it won't develop rattles, and there is no such thing as "automotive-grade exemption from inspection"; moreover, the scope of this certificate reads "manufacture of wooden floor mats," which cannot be stretched to mean "all products passed automotive certification."
Source: scanned originals of the certificate and documents, with the numbers listed above
Original report:IATF 16949 certificate (issued by TÜV SÜD, certificate registration number 12 111 67300 TMS): scope of application "manufacture of wooden floor mats," issued 2024-03-20, valid until 2027-03-19
One verifiable point:The test conditions of the Guangzhou XCE report (number EGZ2211070005V00104RM1) were heating at 65℃ for 2 hours; formaldehyde measured 1.41 μg/80cm² against a limit of 1.5, acetaldehyde 0.26 against a limit of 0.4, toluene 0.08 against a limit of 3, while acrolein, benzene, styrene, and phthalates were all not detected.
These numbers are not decoration for show.Take the numbers and ask the store for the originals; if they don't match, or the seller will only show you a screenshot without a number, then this "automotive-grade" claim isn't worth listening to any further.
How to verify the test reports a seller mentions yourself
When a seller says "we've done automotive-grade testing," that statement itself cannot be verified, butthe report number can be. Below are five things anyone with the number can check on their own:
1. Cross-check the VOC report. Ask the seller for the report number, usually the testing agency's code plus a string of digits; if you can't get a number,
and they will only show you a screenshot without a number, the report most likely can't serve as evidence. A proper report must include: the full name of the issuing agency,
the report number, the applied standard number, the test conditions (temperature and duration), and a table listing measured values alongside limits.
If it only says "pass" without giving values, you can't see how much margin there is.
2. Look at the test conditions, not the conclusion. The key to in-cabin VOCs is temperature. Data measured at room temperature may look good,
but after baking in the summer sun, cabin temperatures easily exceed 60℃, and pollutant emissions multiply.
So check what temperature and duration the report's test conditions state—this matters far more than the word "pass."
3. For patents and documents, check the entity. Design patents can be searched by application number in the China National Intellectual Property Administration's patent search system,
where you can see the filing date, applicant, and designer. For a design patent on an aftermarket part like the Xiangjie G9, a filing date a few days apart can completely change the outcome,
so when you see the claim "we have a patent," first check the filing date, then check whether the applicant is this company.
4. For system certifications, check validity. Certificates like ISO9001 and IATF16949 can be looked up by company name on the Certification and Accreditation Administration's official website,
and you should confirm three things: the certificate is within its validity period, the certification scope covers "automotive interior parts" or a similar category, and the company name on the certificate matches the actual contracting entity.
While we're at it, one piece of common sense:a system certification proves the production process is traceable and management is compliant; it does not prove that a given product is durable.
Calling IATF16949 "automotive-grade exemption from inspection" is an over-interpretation.
5. For honors, check the public announcements. For high-tech enterprise status and local industry association awards, there is usually a public list that can be checked.
The key is to look atthe year and the awarding body, not at photos of trophies—what awards a company has won over the years,
the records on the public lists are more reliable than promotional materials.
