Manufacturing process of Non-Spangle Checkered Galvanized Sheet Q195 Q235 Q345

Galvanized checker plate is a hot-dip galvanized steel plate with raised patterns (usually diamond-shaped) printed on the surface. A protective zinc layer is plated on the surface of the steel through the galvanizing process, which significantly improves its corrosion resistance and wear resistance. It combines the advantages of galvanizing technology and pattern design, and has the characteristics of anti-slip, corrosion resistance, high strength, etc. It is widely used in industry, construction, transportation, and other fields.

There are two different production processes.

1. Rolling by rolling mill

Steel base selection: Use Q235 or Q195 carbon steel or other substrates to obtain high strength and roll to the required thickness.

Hot dip galvanizing: The steel plate is continuously immersed in molten zinc to form a protective layer and solidify.

Embossing: Diamond/linear patterns are pressed out by hydraulic rollers.

Cutting and finishing: Cut to the required length and width according to size.

Quality inspection: Use tools to test the zinc content of the surface coating, measure the coating thickness and plate thickness, and check the coating quality to ensure that there is no blistering or burrs.

This kind of checker plate is flat on one side and the other side is embossed.. It is often used in the chemical industry, railway vehicles, platforms, and other occasions where strength is required.

2. Mechanical stamping

Another type of non-galvanized checker plate is made of hot-rolled or cold-rolled galvanized steel plate, which is made by mechanical stamping. One side is concave and the other side is convex. It is often used for decorative purposes.
