Galvanized/Galvalume Steel

One of the most frequently used surface-treated steel sheets, galvanized steel is a cold- rolled or hot rolled steel plate coated in zinc, with good corrosion-resistant properties. Depending on the type of manufacturing process involved, the steel is divided roughly into hot-dipped galvanized steel and electrolytic galvanized steel categories. Due to its long-term resistance to corrosion caused by sun and rain, the steel is widely used for interior and exterior materials in construction projects, as well as for automotive parts and consumer electronics products. In addition, galvanized steel is the most commonly used material to produce pre-coated metal which is one of the most favored construction materials.

Electrolytic galvanized steel is manufactured by subjecting cold-rolled steel to the deposition of a thin, fine zinc coating by en electrolytic process to help improve corrosion resistance. Compared to hot-dipped galvanized steel, electrolytically-processed steel has better overall surface roughness, greater retention of cold-rolled steel properties and higher workability. It also excels in coating quality and corrosion resistance due to the relatively small amount of zinc deposited and the more consistent and dense rendering of coating.

■ Product Type
· Hot-dipped galvanized steel (GI): Manufactured via the cutting-edge continuous galvanization; features fine, high-quality surface finish
· Galvanized (Fe-Zn) steel (GA): Produced by hot-dipping the steel sheets in a molten zinc-and-aluminum bath to create a Fe-Zn inter-metallic layer which increases welding and coating quality
· Chrome-fee anti-fingerprint zinc coated steel (AFP-GI): A high-end galvanized product with its surface coated organically (1 - 2 μm) to improve durability as well as lubrication anti-fingerprint quality
· Electro-galvanized steel (EGI): A cold-rolled steel widely used as interior and exterior materials for home electronics products thanks to its dense coating quality and fine exterior quality and workability; complies with hazardous substance guidelines (RoHS for home electronics products; EU ELV Directive for automobiles)
