*Coating thicknesses are approximate. *Conversions are based on the following relationship; (1) AL T2 coating: 1 oz/ft2=0.00374 in.; 1 g/m2=0.31131 µm. (2) AL T1 coating: 1 oz/ft2=0.00398 in.; 1 g/m2=0.33128 µm.
Surface characteristic of aluminum, combined with the strength and lower cost of steel.
Excellent resistance to heat and corrosion.
Various coating weights available.
Uniformity of appearance and thickness.
Reflect 80% of radiant heat.
ALUMINIZED STEEL TYPE I & TYPE II
Good atmospheric corrosion standard.
Various coating weights.
Highly reflective of solar heat.
Carbon steel coils are coated according ASTM A463 on both sides with a pure aluminum or an aluminum 5% to 10% silicon alloy. The pure aluminum coated product is called ALUMINIZED TYPE II, and the aluminum-silicon alloy coated one is called as ALUMINIZED TYPE I.
Aluminized sheets have many applications in refineries, the petrochemical industry, gas power plants, oil storage facilities, grain silos, and pipe cladding, automotive industry.
