A roofing or cladding installation is often only as good as the choice of fasteners used. Pretoria-based Flashing Centre has forged an excellent reputation within the sheet metal cladding, facade, flashings and rainwater goods sector. It advises on the importance of knowing what you are specifying, for the integrity of the roof and cladding of the building
Class distinction
Specialised roofing and cladding fasteners are classified for ease of use. Class 3 and Class 4 roofing fasteners are recommended for external roofing applications to ensure longevity and the integrity of the roof. These classes of fasteners are the best against corrosion, with a minimum grade of coating required for external applications.
Specialised roofing and cladding fasteners are vital to ensure the integrity of the roof and cladding of a building.
- Class 3 fasteners are used in places of moderate levels of airborne pollution or coastal areas with low salt levels.
- Class 4 fasteners are more suitable for areas of airborne pollution or coastal areas with moderate to high salt levels.
