Hot Dip Galvanizing Steel Grating

Production Process of Hot Dip Galvanizing Steel Grating

1. Press welding of steel grating

Correction: After cutting, it is usually necessary to correct the flat steel and cross bar. This ensures its flatness.

Welding: Through the pressure welding process, the worker will press the cross bar into the uniform flat steel at high pressure. They then use a powerful welding machine to secure it, creating a strong solder joint. This step determines the main structure and strength of the grid plate.

2. Pickling to remove rust

Pickling treatment: The formed grille needs to be pickled to remove the surface oxide layer and impurities. This step is the key preparation process before hot dip galvanizing. This improves the adhesion and uniformity of the galvanized layer.

3. Hot dip galvanizing

Hot-dip galvanizing: The pickling of the grid plate is immersed in zinc liquid at high temperature (usually 450 ° C ~600 ° C). The zinc reacts chemically with the steel surface to form a dense and strong galvanized layer. This layer of galvanized layer can effectively prevent the oxidation and rust of the steel grid plate in a humid and corrosive environment. Thus extending its service life.

4. Cooling: After hot dip galvanizing is completed, the factory needs to cool the grid plate. This ensures stable performance.

Performance Characteristics

Excellent anti-corrosion performance: the zinc alloy layer formed by hot dip galvanizing process can resist the erosion of corrosive substances such as acid, alkali and salt for a long time. This greatly extends the service life of the steel grille.

High strength and stability: It is welded with high-quality steel, the grating structure is stable, and the bearing capacity is strong. So it can withstand greater pressure and impact.

Good air permeability and water drainage: Special mesh design is used on the grille surface. This facilitates air circulation and rainwater drainage.

Beautiful and durable: Zinc alloy layer surface is smooth and bright, uniform color. This not only improves the overall beauty of the grille, but also enhances its ability to resist UV aging.

Easy to install and maintain: the grid structure is simple, light weight, easy to transport and install. At the same time, its corrosion resistance also reduces later maintenance costs.
