Surface coatings and substrates used in the manufacture of Topclad™ GC have been designed specifically to withstand corrosive atmospheres. Topclad™ GC offers the benefit of a highly polished corrosive resistant surface on the underside of the sheet with a solid-coloured surface to match modern roof colours (Subject to pigment availability) this is achieved by applying an Alsynite 130 micron* EXO-SET 206 Gelcoat layer to the GRP sheeting substrate
Topclad™ GC has no known chemical reaction with any construction materials; The sheeting is resistant to solar deterioration and most corrosive atmospheres; Unaffected by solvents, including hydrocarbons, and provides excellent resistance to most corrosive acids and alkalis
Topclad™ GC can be supplied as fire retardant sheeting when manufactured with FR50 & FR60 resins and can also have the Ultrasafe reinforcing incorporated to be installed without safety netting which is generally omitted in corrosive environments
