Hot dip galvanized iron coil gi coil galvanized steel DX51d, SGCC with regular spangle

Short Description:

Galvanized steel sheet coil features:

The surface oxidation resistance of galvanized steel coil 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. Every part of the plated parts can be plated with zinc, which can be fully protected even in depressions, sharp corners and hidden places.
5. The galvanizing process is faster than other coating construction methods, and the time required for painting on the construction site after installation can be avoided.
6. In general, the cost of hot dip zinc is lower than that of applying other protective coatings.
