Frequently Asked Questions
Q: What fire-retardant grades are available and how do I match them to my market?
A: Fire-retardant treatment is available in grades suited to different regional building and event codes. Confirm the specific classification your local fire authority requires — such as B1, M2, or NFPA 701 — at inquiry stage so the correct grade is applied and a matching test report is supplied with your batch of PVC tarpaulin roll.
Q: How is UV resistance verified before shipment?
A: Anti-UV treatment is applied based on the grade confirmed during specification. A test report documenting the UV exposure methodology and result is supplied with the batch. Request this report at the quotation stage to ensure the treatment level matches the expected outdoor exposure duration of your tensile or shade structure project.
Q: Which welding method works best for tensile structure seams on this 1000D material?
A: HF welding produces strong, flexible seams suitable for high-load tension zones. Hot air welding is effective for long continuous seams on large panels. Sewing with sealed stitch lines is used where mechanical fastening is preferred. The choice depends on your equipment, seam design, and the load conditions at each joint.
Q: How do you control colour consistency across multiple rolls for one project?
A: Each production batch is checked for colour uniformity against the confirmed reference before packing. For projects requiring several rolls installed side by side, we prioritise single-batch production to minimise variation. The pre-shipment inspection record documents this check, and samples can be sent for visual approval before the full order ships.
Q: What custom widths and roll lengths can be ordered?
A: Standard widths are available from stock, and custom widths can be produced to reduce cutting waste on your specific panel sizes. Roll length is configured based on your container loading plan and fabrication workflow. Confirm your required dimensions at inquiry so lead time and minimum order quantity can be quoted accurately.
