400gsm Tarpaulin for Lightweight Fire-Retardant Material Selection
LonaTarp supplies 400gsm tarpaulin for B2B buyers who need a lighter PVC coated fabric with an M2 fire-retardant direction. This material is suitable when the finished product needs easier handling, lower roll weight and fire-retardant performance, but does not require the body or stiffness of heavier PVC tarpaulin grades.
The key purchasing question is not whether 400gsm is “strong enough” in general. It is whether the final product benefits more from lightweight handling than from heavy material body. For temporary curtains, light partitions, simple covers or fabricated products that need to be moved, folded or installed frequently, 400gsm can be a practical starting point if the required fire-performance standard is confirmed before production.
M2 Fire-Retardant Direction Should Be Confirmed Before Sampling
M2 is commonly used by buyers to describe a fire-retardant requirement, but it should not be treated as a universal fireproof claim. The exact test method, required document, market requirement and finished product use should be confirmed before sample approval.
For 400gsm fire retardant PVC tarpaulin, this is especially important because lighter material is often chosen for easy handling. If the project requires flame-retardant documentation, the coating formula, color, surface finish and tested sample direction should match the planned bulk production as closely as possible.

400gsm is useful when the buyer needs fire-retardant PVC coated material but does not want a heavy roll. This can matter for projects where the material will be installed temporarily, moved often, folded by hand or converted into lightweight curtains and panels.
A heavier PVC tarpaulin may provide more body, but it can also increase roll weight, installation difficulty and packing volume. For buyers who prioritize handling convenience while still needing an M2 fire-retardant direction, 400gsm can be a more efficient choice.
Where 400gsm Fire Retardant PVC Tarpaulin Fits Best
This specification can be considered for lightweight divider curtains, temporary partitions, event or project covers, simple protective panels and fabricated products where lower material weight is important. It is not intended for high-tension covers, rough abrasion, heavy dragging or long-term unsupported outdoor spans.
If the final product will be fixed under strong pulling force, repeatedly rubbed against hard surfaces or exposed outdoors for long periods, buyers should review a heavier specification or stronger base fabric. The fire-retardant direction does not replace mechanical strength requirements.
Custom Options for M2 Fire-Retardant PVC Tarpaulin
LonaTarp can customize 400gsm tarpaulin according to the buyer’s project requirements. Available options may include roll width, roll length, color, surface finish, M2 fire-retardant formulation, UV treatment, cold-resistant formulation, printing, labels and export packing.
If a test report is required, the buyer should confirm the standard before sample production. Color, surface finish and coating formula should remain consistent between tested samples and bulk production whenever documentation is needed.
Samples, MOQ and Production Control
For custom 400gsm fire retardant PVC tarpaulin orders, LonaTarp checks production according to confirmed specifications. Inspection points may include finished weight, roll width, roll length, coating uniformity, surface quality, color consistency, packing condition and agreed fire-retardant testing requirements.
Roll material MOQ is 5,000 sqm for custom bulk production. A4 samples can be arranged for initial review, while full-width sample rolls can be charged according to bulk unit price and deducted from a confirmed qualifying order. Normal production lead time is about 15 days after specification approval, depending on order quantity, coating requirement, testing needs and packing method.
