Aluminium Coated Steel Plate

  • Process
  • Packing

Aluminised Steel Sheet can be processed in a variety of methods, but it is essentially cold rolled steel coated or hot ‘dipped’ in aluminium. The aluminium infuses into the steel producing a multiple-layered sheet. A secondary and controlling ingredient, silicon, is added to the dip bath to ensure the aluminium layer is as thin as possible. This hot dipping stage is followed by air drying.

One of the primary purposes is to produce a sheet that has combined aluminium and steel properties. This hot dipped overlay or finish provides the steel added anti-corrosive protection. Although its strength is superior to ordinary steel sheet, its finish is silky smooth to touch with shiny characteristics

Coating Layers  

Types of steel sheets are categorized by the components of the molten pot. Applications are as follows.

Two types of hot-dip are used (Type 1 and Type 2). The full characteristics of aluminized steel are defined by the exact metals used, as well as the processes (Type) used to produce the material.

Type 1 is hot-dip coated with a thin layer of aluminum / silicon alloy that has anywhere from 5% - 11% silicon. The silicon provides improved adhesion of the layers. Type 1 aluminized steel is designed for applications where heat resistance and corrosion resistance are needed. Physical Properties of Aluminized Steel are defined by the exact metals used, as well as the processes used to produce the material.

Type 2 is hot-dipped in commercially pure aluminum. Type 2 is designed for use where atmospheric corrosion resistance is needed.

Typical Uses

Type  1 - Hot-dip coated with a thin layer of aluminum/silicon alloy:

Mufflers

Furnaces

Ovens

Ranges

Water Heaters

Baking Pans

Type 2 - Hot-dip coated with commercially pure aluminum:

Corrugated Roofing/Siding

Grain Bins

Drying Ovens

Air-conditioner condenser housings
