DC51D+Z Galvanzied Steel Coil is a kind of hot dipped galvanized steel under the standard Q/BQB 420-2003. Hot-dip galvanizing is a process of coating steel with a thin zinc layer, which serves as a barrier between the steel and the environment. The finish is applied by passing the steel through a molten bath of zinc at a high temperature.

Advantages of DC51D+Z Galvanzied Steel Coil
♦ Against extreme heat (spangle reflects the sunlight)
♦ Superior rust protection--lifespan 4-6 times longer than PPGI (aluminum has excellent corrosion resistance)
