Excellent weathering and corrosion resistance has been achieved by the 250 g/m2 zinc-aluminium-magnesium alloy coated steel that gives sacrificial protection to the steel core. Combining 93,5 % zinc, 3,5 % aluminium and 3 % magnesium forms an exceptionally stable barrier that is unmatched in the steel roofing industry. Specially selected stone chip granules are applied to provide an attractive textured finish which at the same time enhance resistance to UV radiation. The granules applied in acrylic basecoat are coated with hard coating technology, composed of mineral binder and lightfast pigments. They are cured at high temperature which provides long lasting performance for the ageing of the roof. A final clear acrylic over-glaze is applied before being oven cured. This enables to withstand the harshest environments around the world.
The Gerard Eleganta tile is made of ZM250. ZM250 is a steel that is coated with alloy of 93,5 % Zinc, 3,5 % Aluminium and 3 % Magnesium. The grade of steel used is designed to allow pressing without cracking while at the same time is ridged enough to tolerate reasonable loads.

Transparent protection layer: Clear 100% acrylic resin coating for granule binding and a semi-gloss finish. It helps enhance the appearance as well as increase the resistance to physical damage.
Stone Chip: Carefully selected granules provide excellent surface coverage and attractive natural looking and lasting colours.
Basecoat: A tough opaque coating based on acrylic resin. It bonds the stone chips and protects the underlying layer from water and UV radiation. It has good UV resistance and retains its flexibility although it does become harder after the first few weeks.
Polyurethane primer: The primer is applied by a coil coating process, this coating provides increased corrosion protection and a surface for superior adhesion of the basecoat that is applied.
Polyester Backer Coating: This coating provides increased durability to the underside of the tiles.
