Colorcoat HPS200 Ultra® and Colorcoat® LG pre-finished steel by Tata Steel, available in a choice of colours, offers interesting visual alternatives to traditional lead and zinc standing seam roof systems.

The preferred coating for the aluminium material is PVDF, (polyvinylidene fluoride). These coatings were developed over 30 years ago, the surface finish is smooth with a decorative finish. It is very durable, giving excellent flexibility and chemical resistance combined with the highest possible performance regarding gloss retention, chalking and colour change. An Organic Patina finish utilising a low gloss dull lacquer is also available.

SeamlockZinc® features zinc particles incorporated into a durable coating which is specifically designed as an aesthetic option to naturally weather in a similar way to zinc, rather than retaining a fixed colour. The prevailing conditions of the installed location will influence this and produce different rates of tonal change delivering the aesthetic benefits of a “live” material. The advance coating system is applied over an aluminium substrate which provides a lightweight, durable and cost effective alternative to traditional zinc.

Cold Roof Application

The cold roof system has been specifically designed for use on traditional pitched roofs and is suitable for use with the kind of timber frame that is used in the majority of homes and many large buildings.

Warm Roof Application

The warm roof system embraces the fundamentals of modern metal roofing with inherent thermal performance provided by RocSlab mineral wool insulation, whilst the outer sheet provides the look of a traditional pitched roof.
