The polyester base cloth is what gives the PVC it’s tensile and exceptional tear strength.
This is 1600N/5cm tensile; and 350N/5cm tear strength – based on 700GSM heavy duty PVC.
The PVC thickness is what gives the PVC its weather resistance and weld adhesion strength.
Ours is 80N/5cm.
The above mechanical properties are based on SABS and international best practice standards.
