PE Tarpaulin, 40g~500g/m², Custom Size & Color — polyethylene woven fabric with double waterproof surfaces and reinforced corners, available in lightweight to heavy-duty grades.
Covers moving loads across truck beds, trailers and agricultural stockpiles where weather exposure and abrasion at flex points demand verified GSM and consistent coating weight roll to roll. Every specification — from weave density to UV treatment — is confirmed by sample before bulk production.
Backed by nearly 30 years of coated fabric process control, 100% pre-shipment weighing and inspection, and full documentation including test reports and certificate of origin.
Description
Precision in Every Roll — every polyethylene tarpaulin order is 100% weighed and inspected against the agreed specification before dispatch, so the material you receive matches the data sheet you approved.

Why the Weight Stated on the Quotation Is Not the Weight You Always Receive
The only way to confirm a PE Tarpaulin custom order matches spec is to weigh and inspect every roll before it leaves the production floor.
Buyers regularly open containers and find the fabric feels lighter than the agreed grade. A material specification sheet may state a certain GSM, but without a pre-shipment verification step, there is no evidence the rolls loaded actually met it [NEED_CITE: pre-shipment inspection protocols for coated fabric exports]. The result is covers that tear under load, degrade faster under sun, or fail at the seams well before the expected service life. This is not a defect in the polyethylene itself — it is a gap in the quality checkpoint between coating and container.
Weight Tiers Designed for Specific Load Conditions
The PE tarpaulin range is structured into lightweight, medium and heavy-duty tiers, each with a documented thickness and knitting density. Lightweight grades suit temporary agricultural shelters and indoor warehouse coverage where mechanical stress is low. Medium grades handle regular transport use and outdoor equipment protection. Heavy-duty grades address construction site exposure and industrial transport where abrasion and wind loading demand higher tensile values. Selecting the correct tier eliminates both overspending and premature failure.
Custom Sizing and Colour Without Compromising Batch Consistency
Every PE Tarpaulin custom order supports colour matching and size specification, from small cut sheets for equipment covers to full roll widths for transport fleets. Colour consistency across multiple rolls in one shipment is controlled through in-process monitoring at each coating stage. This prevents the visible banding that appears when adjacent sheets are installed side by side — a problem that often only surfaces on site, well after the material has left the factory [NEED_CITE: colour delta measurement methods for coated polyethylene fabric].
How Base Fabric Density and Coating Weight Work Together
Knitting density — from 5×5 to 20×20 — determines the structural skeleton of the fabric. A higher count means more yarns per unit area, which directly improves tear propagation resistance. However, GSM alone does not predict strength: a heavier coating applied over a low-density base will add weight without proportional gain in tensile performance. The relationship between base fabric, coating weight and finished thickness is why the specification sheet must state all three values, not just GSM. Double waterproof surfaces with reinforced corners add a second layer of protection at the points most vulnerable to water ingress and mechanical wear. UV, mildew and anti-aging treatment is applied during the coating stage rather than as a post-production spray, improving durability of the treatment itself.
The Real Cost of a Specification Mismatch
When a truck cover arrives with a generic size rather than one cut to the trailer model, the fabric either drags on the road or fails to cover the rear load. When a pond liner is supplied without the correct puncture resistance for the substrate, leaks appear within weeks of filling. Colour variation between rolls in the same order becomes visible the moment sheets are installed adjacent to each other on a construction hoarding. These failures share a common root: the specification was assumed rather than verified at each production checkpoint [NEED_CITE: root cause analysis of coated fabric field failures in transport and agriculture].
What Production Control Looks Like Here
Three full production lines and 36 sets of professional equipment provide the capacity for bulk PE tarpaulin orders without compressing lead times. A 10-person R&D team handles material selection, custom sizing and sample development, turning around samples within days for buyer approval before bulk runs begin. Dedicated QA and QC operates at every production stage, with 100% pre-shipment inspection ensuring each roll meets the documented GSM, colour reference and dimension. The coating process is controlled in-house, giving direct authority over coating weight and adhesion rather than relying on external laminators. ISO and CE certified production supports documentation requirements for export markets across North America, Europe and Asia.
Documentation & Verification
- Material specification sheet stating exact GSM, base fabric knitting density and colour reference per roll
- Pre-shipment inspection record confirming 100% weight and dimension check before dispatch
- Roll packing list detailing roll count, individual roll weight and container loading plan
- Certificate of origin included for customs clearance in destination market
- UV and anti-aging treatment documentation — confirm the test basis required for your application
Fabrication, Handling & Storage
- Heat welding parameters depend on coating thickness — confirm settings for the lightweight, medium or heavy-duty grade before production runs
- Reinforced corners and 39.4-inch eyelet spacing distribute tie-down loads across the polyethylene base fabric
- Store rolls upright in shaded, ventilated areas to prevent flattening and crease damage on the PE coating surface
- Unfold and allow custom-size sheets to relax at ambient temperature before installation to avoid tension cracks in cold conditions
- Clean with mild detergent and soft brush; avoid solvents that attack the double waterproof PE surface coating
- Cut-to-size layout should account for hem and eyelet allowance to maximise yield from each roll width
What to Include in Your Enquiry
Provide the intended application and the specific exposure conditions — UV hours, contact with water or chemicals, mechanical loading from wind or tie-downs. State the required weight grade, colour reference and whether you need cut-to-size sheets with eyelets or full roll stock. If your market requires a particular fire classification or UV test standard, specify it at the enquiry stage so the correct grade can be sourced and documented.
Frequently Asked Questions
Q: How is the exact GSM verified on each roll before shipment?
A: Every roll is weighed individually during the pre-shipment inspection. The measured GSM is recorded against the specification stated on your approved material data sheet. Rolls that fall outside the agreed tolerance are separated before packing. The inspection record travels with your shipment documentation so you can cross-reference on arrival.
Q: What UV treatment options are available and what is the test basis?
A: UV, mildew and anti-aging treatment is applied during the coating process for prolonged outdoor exposure. The specific test basis and hours rating depend on the grade selected. Provide your destination market requirements at the enquiry stage so the appropriate grade and corresponding test documentation can be confirmed and included with the shipment.
Q: How do I specify a custom size and eyelet spacing for my truck or trailer?
A: Provide the exact trailer dimensions, preferred eyelet spacing (standard is 39.4 inches centre to centre) and hem reinforcement requirements. A sample is developed within days for your approval, covering size, eyelet placement and corner reinforcement. Bulk production begins only after you sign off the sample specification.
Q: What is the minimum order for custom colour and printed branding?
A: Minimum quantities for custom colour and branding vary by roll width, print complexity and the weight grade selected. Provide your Pantone or RAL reference, total roll count and required width to receive a confirmed minimum and lead time. Colour consistency is monitored across all rolls within the production run.
Q: Do you supply cut-to-size sheets, rolls, or both?
A: Both formats are available. Cut-to-size sheets are supplied with reinforced corners and eyelets as specified. Roll stock is supplied for buyers who fabricate in-house. The roll packing list details individual roll weight and dimensions so you can plan container loading and warehouse staging before the shipment arrives.
