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.

Usages typiques

Overseas inflatable manufacturers buying raw material
Outdoor brands sourcing material for boards and mats
Defence integrators buying base material
Design studios prototyping and small-batch production

Pourquoi une structure gonflable

Building in-house costs less than importing finished goods
Specifiable by thickness, weight and coating
Roll goods ship far more efficiently than inflated products

Quand ce n'est pas le bon choix

This is material supply, not design or process consultancy. The performance of finished products is determined by the buyer's own design and manufacturing, and the supplier does not warrant it.

Caractéristiques en cours de vérification auprès du fabricant

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.
