Topclad GC

Heavy Duty, Corrosion Resistant, Solid Colour

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 manufactures a unique solid-coloured 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.

Technical specifications


  • The surface coatings and substrate used in the manufacture of Topclad have been

  • Available in solid colours to match modern roof colours (subject to pigment availability).
  • Different coloured pigments can be applied to either side of the sheet (this is particularly
