Product Introduction
In 1998, Dongbu Steel was licensed by BIEC International Inc. to produce SuperGalum Color.
- Prepainted 55% Aluminum-Zinc alloy coating steel sheet (SuperGalum) with a variety of coating options is available to meet the needs of our customers
- Ultra corrosion resistance of aluminum, as well as the sacrificial anodes of zinc are ideally combined to create a highly corrosion resistant prepainted steel sheet which is 3~6 times more durable than conventional hot-dip coated steel sheet.
Durability
Offers three to six times greater durability compared with galvanized steel sheet coated at the same thickness
Cost efficiency
The density of a 55% Al-Zn coating layer is lower than that of zinc coating, increasing the surface per ton by approximately 1~3%.
Superb paintability
Adhesiveness between the coating layer and paint is superior to galvanized steel plates.
Excellent workability
The level of workability is identical to that of galvanized steel sheet. Due to its ability to prevent fine cracks from developing, durability of the treated portion is also high.
