What is MC900 Knife-Coated PVC Tarpaulin?
High-speed doors live a hard life: the curtain rolls, flexes and reverses thousands of times a day, and the fabric is the first component to wear out. The MC900 is a 900 g/m² knife-coated PVC tarpaulin built for exactly this duty — high-speed doors and industrial curtains — using the same 1000D × 1000D yarn and 30 × 30 thread density as GaiaTextile’s heaviest door grade, with the same 3900N/5cm warp tensile strength, but in a lighter, more budget-friendly 900 g/m² base.
For project buyers the calculation is straightforward. A door curtain does not need to be heavier than its engineering requires; it needs the right strength-to-weight balance so the motor, barrel and guides are not overloaded and the panel does not cost more per square metre than it has to. The MC900 delivers full door-grade strength at a weight that keeps both installation and material budgets in check. Fabricators who weld their own curtains also benefit: a lighter base is easier to cut, seam and handle on the bench, without giving up door-grade strength.
Knife-Coated vs. Other PVC Coating Methods
Knife coating spreads a controlled layer of PVC paste across the polyester base with a doctor blade before oven fusion. The result is a coating thin and even enough to fold cleanly — essential for door curtains that reverse direction hundreds of times a day — yet so strongly bonded to the yarn that it resists peeling at the fold line. A laminated fabric can separate between its film and scrim under constant flexing; a knife-coated fabric behaves as one continuous material. That bonded structure is why the MC900 suits both full-width door panels and sectional curtain installations without reinforcement changes. Because the coating is fused rather than laminated, there is no adhesive layer that can degrade with heat or age — one less failure mode in a component that is cycled all day.

How Does MC900 Compare to MC1050?
| Property | MC900 | MC1050 |
|---|---|---|
| Total weight | 900 g/m² | 1050 g/m² |
| Yarn / density | 1000D×1000D / 30×30 | 1000D×1000D / 30×30 |
| Tensile (warp/weft) | 3900 / 3700N | 3900 / 3700N |
| Tear (warp/weft) | 600 / 550N | 600 / 550N |
| Best for | Standard-cycle doors, weight- and budget-sensitive projects | Heavy-cycle doors, high abrasion, large panels |
When to choose MC900: choose the MC900 when your door or curtain must meet the same strength class as the heaviest grade but the project is sensitive to weight or budget. The 150 g/m² difference versus MC1050 (900 vs 1050 g/m²) trims roll weight, so panels are easier to handle, install and tension, while yarn, density and tensile strength stay identical. If your door cycles several hundred times a day or the curtain takes constant scraping, step up to the MC1050; for standard-cycle doors and industrial curtains, the MC900 delivers the same engineering margin for less. For multi-door sites, standardizing on the MC900 across standard bays also simplifies spare-part stock and maintenance planning.
Key Features and Benefits
- Full door-grade strength at 900 g/m² — the same 3900N/5cm warp tensile as our heaviest door fabric, without the extra weight.
- 600N warp / 550N weft tear strength (DIN 53363) — survives snags at dock seals and forklift contact.
- B1 flame retardant (DIN 4102) — fire-safety classification accepted across European industrial buildings.
- −30°C to +70°C operating range (DIN EN 1876-1) — reliable flexing in cold stores and heated halls alike.
- UV aging ≥ 4 and color fastness ≥ 7 — the curtain keeps its appearance and mechanical properties in outdoor-facing installations.
- Coating adhesion ≥ 60–80N/5cm (EN ISO 2411) — no peeling at fold lines even after months of cycling.
- 50/100 m roll lengths — convenient ordering for multi-door rollouts and curtain fabrication.

FAQ
What is the difference between MC900 and MC1050?
Weight and price per square metre. MC900 is 900 g/m², MC1050 is 1050 g/m²; construction and tensile strength are identical. Pick MC900 for standard-duty doors where weight and budget matter.
Is 900 g/m² heavy enough for a high-speed door?
Yes. The MC900 carries the same 3900N/5cm warp tensile as the 1050 g/m² grade, so it is not a downgrade in strength — it is a lighter construction with the same engineering performance. The specification has proven itself in standard warehouse doors, where the working load is tension and flexing rather than impact.
How does MC900 compare with laminated door fabric?
Knife coating produces a single, uniformly bonded layer that folds and flexes without separating from the scrim. Laminated film can peel at fold lines under constant cycling, which is why knife-coated construction is preferred for door curtains.
Is MC900 flame retardant?
Yes, it is classified B1 (flame retardant) under DIN 4102.
What temperature range can MC900 handle?
From −30°C to +70°C, so it works in cold storage and in unconditioned industrial halls.
What widths and roll lengths are available?
Standard rolls are 50 m or 100 m. Width, GSM and color are made to your specification — tell us what you need and we confirm within 12 hours.
