What is drop-stitch fabric?

Drop-stitch fabric is two layers of coated base cloth joined by tens of thousands of internal threads of equal length. Inflated, those threads hold the two faces parallel, turning the fabric into a rigid panel with defined thickness.

How is drop-stitch fabric made?

The two faces and the connecting threads are woven or knitted together on a specialised machine, then coated with PVC or TPU. The thread structure is created during weaving and cannot be added afterwards.

What thickness of drop-stitch fabric is available?

Commercially available chamber depth runs roughly five to thirty centimetres, covering paddleboards, boat decks, gym mats and most shelter walls. Anything outside that band should be confirmed with the mill before you design around it.

Is TPU better than PVC for drop-stitch?

TPU stays flexible in cold, ages better under UV and is lighter for the same strength; PVC costs less, welds faster and offers a wider colour range. For temperate seasonal use PVC is usually the right commercial answer.

Flame-Retardant Coated Fabric

阻燃膜材

Technical fabric treated to a flame-retardant standard, for applications with fire requirements.

flame-retardant coated fabric deployed on site, in use — In use on site

Usos típicos

Public venues and places of assembly
Emergency shelter and medical applications
Military and oil and gas environments
Any project with a stated fire standard

Por qué una estructura inflable

Most government and humanitarian procurement treats fire rating as mandatory
Without a fire report the bid does not qualify at all

Cuándo no es la opción adecuada

Fire rating must come from a third-party test report, and the standards are not interchangeable — EN 13501, NFPA 701 and GB are different systems. Testing to the wrong one is money spent for nothing.

Especificaciones pendientes de verificación con el fabricante

Working pressure, membrane thickness, tensile and tear strength, weight, packed volume, deployed dimensions, fire rating and warranty are being verified with our manufacturing partner and independent laboratories. We publish figures when they are documented, not before.
