Galvalloy^®

Colorcoat Prisma^® uses the unique and proven Galvalloy^® metallic coating by Tata Steel. Galvalloy^® is made with a special mix of 95% Zinc (Zn) and 5% Aluminium (Al) that conforms to EN 10346:2015. The carefully developed proportions of Zinc and Aluminium in Galvalloy^® offers a combination of increased barrier and sacrificial protection when compared with conventional Hot Dip Galv (HDG) coatings and provides unrivalled corrosion protection, even at the cut edges.

FIRE PERFORMANCE

Reaction to fire

Performance of roof coverings

Colorcoat Prisma^® - Textured is deemed to satisfy, without the need for further testing, the requirements for external fire performance of roof covering products in accordance with Commission Decision 2000/553/EC. This is valid for all gauges ≥ 0.4mm and for all colours in the product range for single sided product.

Colour consistency
If tonal consistency is critical, all cladding for a single elevation should come from the same production batch. All metallic shades exhibit a degree of directionality.  

Matching components
If accessories made from other materials are to be colour-matched to the roof or wall cladding, the best reference is the actual profiles or panels delivered to site, or material from the same batch.

Metal hand samples
Metal hand samples are available for all colours. For a truer representation of colour and effect, please obtain metal hand samples.
