China aluminum zinc steel coil factory is here today to tell you about the different performance characteristics of steel coils:
A. Heat reflective
Aluminum-zinc coils have high thermal reflectivity, twice that of galvanized steel sheets, which are often used as insulation materials.
B. Heat resistance
Aluminium-zinc steel coils have good heat resistance and can withstand temperatures of more than 300 degrees Celsius. They are similar to the high-temperature oxidation resistance of aluminized steel sheets and are often used in chimney tubes, ovens, illuminators, and fluorescent shades. Corrosion resistance:
The corrosion resistance of aluminum-zinc steel coils is mainly due to the protective function of aluminum and aluminum. When the zinc is worn, the aluminum forms a layer of dense alumina that prevents the corrosion-resistant material from further corroding the interior.
C. Economics:
Since the density of 55% of AL-Zn is smaller than the density of Zn, the aluminum-zinc-plated steel sheet is larger than the area of the plated steel sheet by 3% or more in the case where the weight is the same as that of the gold-plated layer.
D. Easy to paint
Excellent adhesion between aluminum-zinc steel coils and paint, lacquering without pretreatment and weathering.
