G550 / DX51D+Z Galvanized Steel Strip For Steel Frame And Construction

Short Description:

G550 Galvanized steel strip with width 50-500mm, widely used for steel structure, building and construction.

The surface oxidation resistance of galvanized steel strip is strong, which can strengthen the anti-corrosion penetration ability of parts.

1. Low processing cost.
2. Durable. The durability of the coating is reliable.
3. The coating has strong toughness.
4. Galvanized steel strip can be fully protected even in depressions, sharp corners and hidden places.
5. In general, the cost of hot dip zinc is lower than that of applying other protective coatings.

Galvanized steel coil/strips are widely used for construction, building, roof sheets, automobiles, agriculture,home appliances,vanitation pipe and commercial industries.

The galvanized steel strip base material can be divided into cold-rolled steel and hot-rolled steel. The thicness of galvanized strip with cold rolled steel is 0.12-2mm, while the thickness of galvanized strip with hot-rolled steel material is 2-5mm. The steel grade for cold rolled galvanized steel strips are G550, DX51D+Z, S350,S550, Q195, Q235, SGCC. The strip is generally slit from galvanized steel coils which width from 600-1500mm, so that any strip width is available.
