Types
- Type 1
Hot-dip coated with a thin layer of aluminum/silicon alloy containing 5% to 11% silicon to promote better adherence. It is intended principally for heat resisting applications and also for uses where corrosion resistance and heat are involved. Possible end uses are mufflers, furnaces, ovens, ranges, heaters, water heaters, fireplaces, and baking pans.
Aluminized Steel can with stand 550 degree celsius with almost no change in the base material. But due to silicon content it develops black spot.
Aluminized steel has slowly started to convert bakery trays which was previously made by galvanize or galvalume steel as it dose not contain lead which is poisons for human health.
Type 1 is also commonly found in industrial products.- Type 2
Hot-dip coated with commercially pure aluminum. It is intended principally for applications requiring atmospheric corrosion resistance. Type 2 may ultimately be manufactured into corrugated roofing and siding, grain bins, drying ovens, and air-conditioner condenser housings.
