What is Keder Tarpaulin?
Keder tarpaulin is a reinforced PVC coated fabric used for welding with keder core (polyester or PVC cord) to form a smooth, strong edge that slides into an aluminum keder rail. It is widely used in tents, exhibition halls, truck curtain siders, inflatables, banners, awnings, and textile structures.

A typical keder consists of:
- PVC or TPU coated tarpaulin – the outer fabric layer
- Keder core – solid PVC cord or polyester rope
- High-frequency or hot-air welding to seal the core inside
DERFLEX keder tarpaulin is designed for high tensile strength, anti-tear performance, and excellent weldability. Our products ensure smooth channel movement, long outdoor lifespan, and strong load-bearing performance.
