Description
What is KC900 Knife-Coated PVC Tarpaulin?
Some covers get replaced every season; the KC900 is for the ones that are meant to last. This 900 g/m² knife-coated PVC tarpaulin, industrial grade, is engineered for covers and protection fabrics that must survive abrasion, wind loading and years of outdoor exposure. On a 1000D × 1000D polyester base at 30 × 30 thread density, it delivers 3900N/5cm warp tensile strength, 3700N/5cm weft, and 600N warp tear strength — top-of-range numbers in the GaiaTextile industrial cover line — with B1 flame retardancy (DIN 4102) as standard.
What separates an industrial-grade cover fabric from a general-purpose sheet is not one single number but the combination of them: heavy weight for wind stability, tight weave for dimensional stability, high tensile for pull loads and high tear strength for the snags and scrapes that happen on any real site. The KC900 stacks all four, which is why it is specified for covers that cannot be allowed to fail mid-season. For buyers, that means a single fabric specification can cover everything from machine covers to yard protection, simplifying procurement.
Knife-Coated vs. Other PVC Coating Methods
Industrial-grade knife coating lays a PVC paste onto the scrim in a controlled doctor-blade pass and fuses it to the yarn, producing a coating that is thick enough to absorb abrasion and uniform enough to have no weak points. Where a thin laminated film can lift away from the base when a cover is dragged across concrete or gravel, a knife-coated surface is locked to the fabric structure — coating and scrim flex, stretch and wear as one. That bond is what keeps a KC900 cover watertight after months of wind loading, repeated handling and constant UV exposure, and it is the reason knife-coated construction remains the standard for demanding cover applications.

How Does KC900 Compare to KC650?
| Property | KC900 | KC650 |
|---|---|---|
| Total weight | 900 g/m² | 650 g/m² |
| Yarn / density | 1000D×1000D / 30×30 | 1000D×1000D / 20×20 |
| Tensile (warp/weft) | 3900 / 3700N | 2600 / 2200N |
| Tear (warp/weft) | 600 / 550N | 320 / 290N |
| Best for | Heavy-duty covers, high abrasion, wind exposure | Lighter static covers, budget projects |
When to choose KC900: move up to the KC900 when a cover has to do real work — dragged across floors, tied down in high winds, or fitted over sharp-edged loads. Compared with the lighter KC650 grade, the 900 g/m² base and 30 × 30 density lift warp tensile by 50% (2600N to 3900N/5cm) and nearly double tear strength (320N to 600N), while the heavier weight also makes large panels more stable under wind loading. If your covers sit undisturbed in a sheltered yard, KC650 remains the economical choice; the KC900 pays for itself the moment abrasion or weather gets serious. And because the 900 g/m² weight sits at the top of the cover range, KC900 panels stay put in gusty conditions without extra ballast.
Key Features and Benefits
- 3900N/5cm warp and 3700N/5cm weft tensile (EN ISO 1421) — top-of-range strength for pull and wind loads.
- 600N warp / 550N weft tear strength (DIN 53363) — resists punctures and edge tears from dragging and sharp contact.
- 30 × 30 thread density — a tight, stable surface that holds its dimensions and resists distortion.

FAQ
What makes KC900 an industrial-grade fabric?
Its combination of heavy 900 g/m² weight, tight 30 × 30 weave, 3900N/5cm tensile and 600N tear strength — engineered for covers that face abrasion and weather year-round. It is the same strength profile used across heavy cover programs where failure is not an option.
How does KC900 compare with KC650?
KC900 is the heavier, tougher upgrade: 900 vs 650 g/m², 30 × 30 vs 20 × 20 density, 3900N vs 2600N warp tensile, and 600N vs 320N tear strength. Choose KC900 where abrasion and wind are a real risk.
Can KC900 be used outdoors year-round?
Yes. It works from −30°C to +70°C and passes UV aging ≥ 4 (ISO 4892-3) and color fastness ≥ 7 (ISO 105-B04), so it is built for continuous outdoor exposure.
How strong is KC900 in terms of tear?
Warp tear strength is 600N and weft 550N per DIN 53363 — roughly double the tear resistance of the lighter KC650 grade.
Is KC900 flame retardant?
Yes, it is classified B1 (flame retardant) under DIN 4102.
What temperature range does KC900 tolerate?
From −30°C to +70°C per DIN EN 1876-1, covering cold stores and hot outdoor sites.
