WHAT IS A PRÉCONTRAINT SERGE FERRARI COATED COMPOSITE MATERIAL?
- a woven base cloth of high tenacity polyester threads,
- a coating with the membrane under constant tension in both the warp and weft directions throughout the entire manufacturing process
- a high performance polymer surface layer with a constant and greater thickness over the top of the yarns,
- a dirt-resistance surface treatment.
- un traitement de surface anti-salissure
Controlled dimensional stability
Précontraint Serge Ferrari technology guarantees the material’s exceptional dimensional stability, which is almost identical in warp and weft directions. Deformation resistance in the weft direction exceeds that of conventional coated fabrics. This exclusive advantage is very important during textile tensioning.
Précontraint Serge Ferrari composite materials offer high resistance to stretching due to their very low absorbency.
In addition, due to the dual advantage exceptional stability and straight threads, Précontraint Serge Ferrari composite materials stretch three times less with the weft than conventional coated fabrics.
Longation in the weft direction under a 200 daN/m load over a period of 100 hours.
Then residual elongation without load.
Totally controlled uniformity
The bi-axial tension central to Précontraint Serge Ferrari technology ensures rigorous control of weft threads and absolute running thread compliance throughout all production batches.
Précontraint Serge Ferrari® membranes ensure total compliance along the thread, (identical throughout all production batches).
The weft threads of conventional coated fabrics deform significantly and variably depending on the production batches.
Material lightness during handling is an important criteria in facilitating making up and installation. Précontraint Serge Ferrari technology ensures this lightness, whilst guaranteeing a thicker coating layer at the top of the yarns. The polyester base cloth is therefore better protected against climatic conditions.
Thicker coating on the thread crests ensures that the physical properties of Précontraint Serge Ferrari membranes are preserved over time – a key factor in the durability of your projects.
