Galvalume steel coil
55% AI-Zn ALLOY-COATED STEEL COILS
The aluminum-zinc alloy for 55% Al-Zn alloy-coated steel coils consists of 55% aluminum, 43.4% zinc and 1.6% silicon, solidified at 600ºC high temperature. The whole structure is a quaternary AI-Fe-Si-Zn compound which becomes a protection layer on the steel sheet to prevent penetration of corrosive factors effectively.
CHARACTERISTICS
CORROSION RESISTANCE
The improved corrosion resistance of 55% AI-Zn alloy-coated steel coils is derived from the unique combination of the barrier protection of the aluminum and the sacrificial protection of the zinc. The formation of an insoluble aluminum oxide layer provides the barrier protection while the zinc provides a sacrificial protection at cut edges, scratches and areas of coating damage.
Outdoor exposure testing of 55% AI-Zn alloy-coated steel onus has been conducted for over 20 years in various atmospheric environments. This testing also demonstrated a superior cut edge protection of 55% AI-Zn alloy-coated steel sheet than the galvanized steel sheet
HEAT RESISTANCE
Similar to the aluminum coated steel sheet that can resist high temperature oxidation, 55% AI-Zn alloy-coated steel sheet demonstrates better resistance to high temperature than the galvanized steel sheet. 55% AI-Zn alloy-coated steel sheet can be used in temperatures up to 315ºC.
HEAT TRANSMISSION AND REFLECTIVITY
55% AI-Zn alloy-coated steel coil has a high reflectivity value making it an effective barrier against heat.
