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.
Available Thickness, Width & Grade
Thickness: .009" to .060"
Width: 36.00" to 60.00"
Grade: CQ/LFQ, GRD 33, GRD 40, GRD 50, GRD 80
Min & Max Coil Weights: 10,000lbs to 25,000lbs
Zinc Coating Weights: AZ35, AZ50, AZ55, AZ120
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.
