Galvanized Steel
The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. Some of the applications for galvanized steel coils/sheets:
Galvalume Coated
A steel with a coating layer made from almost 55% aluminum & 45% zinc.
Galvalume is recommended when a high level of corrosion resistance is important:
Applications include:
- pre-engineered metal buildings
- industrial roofing and siding
- air-conditioning equipment
- building panels
- electrical boxes
- farm equipment & machinery
- furnace parts
- guide rails
- heating equipment & appliances
Prepainted Galvanized
A steel with double protective layers of paint and zinc, where the steel is painted before forming.
It is widely used in:
- construction
- home appliances
- furniture
- utilities
- transport
Electrogalvanized Steel
Electrogalvanized steel is manufactured by electroplating a pure zinc coating on one or two sides.
In addition, the coated surface has a smooth, matte appearance.
Thus, the surface quality is exceptionally good for applications that require a high finish after painting, such as automotive exposed panels.
