color coated roofing & wall cladding sheets

COLOR COATED ROOFING & WALL CLADDING SHEETS

Below are three types of corrosion protected steel for roof and wall cladding applications.

Pre-painted Galvanized Steel (Zinc Coated Steel)

Pre-painted Galvalume Steel (Zinc-Aluminium Alloy Coated Steel)

Bare Galvalume Steel (Zinc-Aluminium Alloy Coated Steel)

Galvanized Steel: Zinc metallized coating can provide corrosion protection in rural and urban areas. Atmospheric conditions will not rust steel protected by a Zinc metallized coating. Therefore, a Zinc metallized coating does not distort the shape of the steel nor it will affect its metallurgical structure. If the product is scratched and the based metal is revealed, zinc will sacrifice itself and protect the exposed area until it is consumed entirely.

Product	Sheet Width	Effective Width	Crest Depth	Crest Distance
Thickness (TCT)Trapezoidal Profile	1100mm	1000mm	27mm	200mm c/c with 2 ribs at the center for stiffening

Technical Specifications

Pre-painted Galvanized Steel
Thickness (TCT)	0.30mm – 0.80mm
Base Metal	Z 120 (total on both sides) Higher or lower coating optional.
Base Metal	High Tensile & Soft Material / CR

Galvalume Steel: Zinc-Aluminium alloy coating gives corrosion resistance and superior heat reflectivity. Galvalume Steel reflects a high percentage of heat and can withstand in any weather conditions, without surface discoloration. It is also suited for coastal areas. Bare Galvalume coating is inorganic and does not contain volatile compounds that can harm the environment.
