Thickness
VIVA ACPs are readily available in 6mm, 4mm and 3mm with the Aluminium coil thicknesses varying from 0.25 mm to 0.50mm. The thickness of ACP’s can be made customized on special order/requirement or as per largely depends on the height at which it is to be installed mainly because of the wind velocity that will differ at that altitude upto 10mm.
