Galvanized steel is to prevent surface from corrosion and prolong the service life of the steel surfaces, coated with a layer of metal .zinc the king of zinc coated thin plate called galvanized sheet..
Hot-dip galvanized is hot - rolled steel coils, or cold-rolled steel as a substrate, after a continuous hot-dip galvanized process and then produced. The cross-section to a rectangular plate which for supply is hot dip galvanized sheet; by the take -up in order to supply hot roll galvanized volumes. Therefore, hot-dip galvanizing can be classified into hot-rolled coils galvanized coils and cold rolled coils, which are mainly used in construction, housed hold appliances, automobiles, container, transport and family business and other fields, in particular, steel construction, automobile manufacturing, steel silo manufacturing and other industries.

Type of Galvanized Spangle:
Galvanized with regular spangle, zinc-coated from 30g to 275g(g90). thickness from 0.15mm to 2.0mm. Regular spangle galvanized can be used in hot and wet outdoor places. For example fence, roofing, garage door, etc.
Galvanized with zero spangles, this kind of GI with brightly surface, zinc-coated from 30g to 2755g(g90). thickness from 0.12mm to 0.25mm. It could be used outdoor also. Currently mainly exported to Southeast Asia and Africa. It is cheaper than gi with regular spangle. This product can be processed later, for example, processed into stone coated tiles.
How long the service life of regular spangles and zero spangles galvanized?:
