Coating weight controlled at source — Every roll of 900GSM PVC coated tarpaulin for lorry curtains is produced on-site with coating weight verified against specification before it leaves the line, eliminating the mismatch between quoted and delivered fabric.

Why Lorry Curtain Fabric Fails at the Flex Points Before the Main Panel Does
The weakest zone on any lorry curtain is where the fabric bends repeatedly around rollers and tie-down points, not the broad panel surface.
When a PVC coated tarpaulin for lorries flexes thousands of times over a single journey, the coating-to-base-fabric bond is tested at every fold. If the adhesion between PVC coating and polyester base yarn is weak, micro-cracks form along the fold line. These cracks propagate with each flex cycle until the coating delaminates and the underlying yarn is exposed to abrasion and water ingress. Fleet operators then face the cost of full curtain replacement mid-route rather than a localised repair. [NEED_CITE: tensile and tear test methods for coated fabrics per ISO 1421]
Curtain Fitment That Matches Your Trailer, Not a Generic Template
A standard-size PVC coated tarpaulin for lorries rarely matches the exact rail-to-rail distance and door opening height of a specific trailer model. Gaps at the top rail allow water ingress onto the load, while excess fabric flaps at speed, accelerating wear at the roller mounting points. This fabric is cut and finished to the exact dimensions of the trailer it will cover, so the curtain sits flush against the rails and the bottom edge seats correctly in the tensioning bar without slack or over-stretch.
Reinforcement Where the Load Path Demands It
Tie-down straps and curtain rollers concentrate force into small fabric areas. Without localised reinforcement, eyelets pull through the base fabric and hem stitching unravels under repeated load cycles. The hem and eyelet layout on this PVC coated tarpaulin for lorries can be specified to match the spacing of your existing tie-down hardware, placing reinforcement exactly where the load path runs rather than at generic intervals.

Reading the Specification Sheet Beyond the GSM Figure
The 900GSM weight grade indicates total fabric mass per square metre, but tensile and tear performance depends equally on base fabric denier and weave density. A 900GSM fabric built on a 1000D×1000D base will resist tearing at curtain flex points more effectively than the same weight laid over a lighter 200D×300D weave, because the individual yarns carry higher load before breaking. Coating adhesion strength determines whether the PVC layer stays bonded to the base yarn through thousands of fold cycles on a lorry curtain roller, and this property is governed by the coating method rather than weight alone. Surface finish selection — glossy or matte — affects both visibility for fleet branding and the ease with which road grime can be cleaned from the curtain face during routine maintenance.
The Hidden Cost of Specifying on Price Per Metre Alone
When procurement decisions are driven by cost per square metre without verifying delivered weight, the fabric arriving at the depot may be lighter than the quotation stated. A curtain installed at a lower GSM than designed will reach its fatigue limit at the flex points sooner, forcing the fleet into unplanned replacement downtime. Colour inconsistency between rolls in the same batch order becomes visible once curtains are hung side by side on a multi-bay trailer, requiring a full re-order to restore a uniform fleet appearance.

Production Capability Behind This Fabric
Three full production lines and 36 sets of professional equipment support bulk orders with on-time dispatch for fleet curtain programmes. A 10-person R&D team handles pattern layout, custom sizing and sample development specific to lorry curtain fitment requirements. Dedicated QA/QC runs at every stage of coating, with 100% inspection before shipment and a pre-shipment inspection record supplied with each order. Nearly 30 years of focused coated fabric production provides the process control needed to hold GSM and colour consistency across a multi-roll fleet order. Samples for custom widths, colours or eyelet layouts are developed within days so fitment can be confirmed before bulk production begins.
Documentation & Verification
- Material specification sheet stating GSM, base fabric denier, coating type and colour reference for each roll
- Weight verification per roll against the stated 900GSM before dispatch
- Test report for UV and flame-retardant grades supplied where applicable to the order
- Pre-shipment inspection record covering surface quality and dimensional accuracy
- Roll packing list and certificate of origin included with each shipment
- ISO and CE certificates provided with documentation package
Fabrication, Handling & Storage
- Heat welding parameters should be adjusted for 900GSM material to ensure full coating fusion at seam overlaps without scorching
- Eyelet installation on 900GSM curtain panels requires sufficient washer diameter to distribute tie-down load across the base fabric weave
- Store rolls upright on a flat surface to prevent permanent creasing in the PVC coating layer that shows through on installed curtains
- Allow cold-stored rolls to reach ambient temperature before unrolling to avoid cracking the PVC coating at low temperatures
- Clean matte finish surfaces with mild detergent only, as aggressive solvents can degrade the surface treatment on this PVC coated tarpaulin for lorries
What to Include in Your Enquiry
Provide the exact trailer model, rail-to-rail width and curtain drop length so that the PVC coated tarpaulin for lorries is cut to fit without on-site adjustment. Specify the base fabric denier you require and whether glossy or matte finish is preferred for fleet appearance. Confirm any fire-retardant or UV treatment grade your operating region mandates, and indicate the eyelet spacing and hem reinforcement layout that matches your existing curtain hardware.
Frequently Asked Questions
Q: How is 900GSM verified on arrival and what tolerance applies?
A: Each roll undergoes pre-shipment weight verification against the specified 900GSM grade, and the inspection record travels with the shipment. On receipt, you can confirm weight by cutting a measured sample and weighing it against the stated tolerance band. We supply the full inspection documentation so any discrepancy is traceable back to the production batch.
Q: How are lorry curtains sized to fit specific trailer models rather than generic dimensions?
A: We cut the PVC coated tarpaulin for lorries to the exact rail width, door opening height and roller mount positions of your trailer model. You supply the model reference or measured dimensions, and the curtain panels are finished with hems and eyelets positioned to match your hardware layout, eliminating on-site trimming.
Q: What eyelet spacing and hem reinforcement options handle tie-down and flex-point loads?
A: Eyelet spacing and hem reinforcement are configured to your tie-down hardware pattern and the flex zones specific to curtain-sider operation. Reinforced patches can be added at high-stress points around roller mounts and bottom tensioning bars to extend service life at these failure-prone areas.
Q: How is colour consistency maintained across multiple curtains for one fleet?
A: All rolls in a single fleet order are produced from the same coating batch with colour reference checked against the approved sample. The pre-shipment inspection record confirms colour consistency across every roll so that curtains hung side by side on adjacent trailers present a uniform appearance.
Q: What UV or flame-retardant test reports are supplied with the shipment?
A: Where UV or flame-retardant treatment is specified in the order, the corresponding test report is included in the documentation package. The specific grade and test standard depend on your market requirements, so confirm the applicable regulation at enquiry stage so the correct treatment and certification are applied to your PVC coated tarpaulin for lorries.
