In some highly corrosive industrial sites and areas of high salt contamination, high-build paint coatings on roofing and cladding substrates such as aluminium and steel may not perform as expected. 

To address these concerns, Alsynite New Zealand manufactures a unique solidcoloured heavy duty roofing and cladding material using advanced GRP technology. This formulates a corrosion-resistant cladding system for use as an innovative replacement for traditional materials.

Features and Benefits

 

The surface coatings and substrate used in the manufacture of Topclad™ GC have been designed specifically to withstand corrosive atmospheres. The added benefit that Topclad™ GC provides is the highly polished corrosion-resistant surface on the underside of the sheet.

Topclad™ GC is solid-coloured to match modern roof colours (subject to pigment availability). This is achieved by applying a 100-micron Silmar® SIL12BE-1659 coloured gel-coat layer to the GRP sheeting substrate.

Advanced technology associated with the Alsynite NZ gel-coat manufacturing process allows different solid colour pigmentation to be applied to each side of the sheet. This is particularly important where the underside of the sheet is not covered by a membrane.
