Aluzinc Steel

Aluzinc Steel is a Hot Dip Process of Aluminium Zinc bath.

Composition of coated layer:

Composition Weight% Capacity Ratio%
Aluminium 55 80
Zinc 43.4 19
Silicon 1.6 1

Durability
Aluzinc has 3 to 6 times superior corrosion resistance compared to zinc coated (galvanize) steel sheet of same coating thickness. This material is imported from South Korea with a 20 years warranties in case of residential application with conditions.

Heat Reflectivity
Aluzinc has superior heat reflectivity, which leads to cooler area inside which helps increase efficiency and life of the products inside. Lowers the cost of air conditioning, mainly used in food storage, control panels, roofing etc.

Paintability
Aluzinc has better adhesiveness of paints to its coated layer compared to galvanized steel sheet. Aluzinc used for general purposes dose not require any pre treatment before painting.
