Zincalume Steel Coil Price Mild Steel Coil Zinc Alu Steel Supplier
Galvalume steel is the composition of coating 55% aluminum, 43.4 % zinc and 1.6 % silicon. The coating
is also applied by means of a continuous hot dip galvanizing process. Aluzinc-zinc coating offer an excellent
corrosion resistance resultant from the barrier effect of the aluminum on the surface and the sacrificial prot
-ection of zinc. Aluzinc has a clean, natural and bright silvery surface. The surface includes small spangles
that give it a lustrous and striking appearance as light conditions change.
Advanges of Galvalume Coil Material
Corrosion Resistance
The improved corrosion resistance of 55% Al-Zn Alloy Coated Steel Coils are derived from the unique combination
of the barrier protection of Aluminum and the sacrificial protection of Zinc. The formation of an insoluble Aluminum
oxide layer provides the barrier protection while Zinc provides a sacrificial protection at cut edges, scratches and
areas of coating damage.
Heat Resistance
Similar to the Aluminum Coated Steel Sheet that can resist high temperature oxidation, 55% Al-Zn Alloy-Coated
Steel Sheet demonstrates better resistance to high temperature.
Heat Transmission & Reflectivity
55% Al-Zn Alloy-Coated Steel Coil has a high reflectivity value making it an effective barrier against heat.
