Products Description
Steel gratings are made by the load bearing bar and crossing bar (twisted square steel, square steel, round steel, flat steel, etc.) arranged in a certain distance between warp and weft.They are made to the original plate on the high-voltage resistance welding machine welding.After cutting, incision, hole opening, cover edge and other process, they become the products which meet customer’s requirements.
Hot-dip galvanizing is the most effective, economical and durable process to protect steel from atmospheric corrosion. The process is based on immersing the steel in a 450º molten zinc bath. The zinc covers the steel and protects it from atmospheric oxidation processes.
