Introduction
Chequered steel plate is a kind of structure steel produced by hot rolling type and cold rolling type hot rolled chequered steel plate includes 4.5mm, 6.0mm, 8.0mm，and 10mm thickness. Chequered steel plate can be divided into gas shield welding chequered plate and submerged arc welding chequered plate according to process. Hot rolled chequered steel plate is mainly for high strength flat steel (hot rolled coil) of ordinary low quality carbon structural steel and low alloy steel, including ordinary steel (Q235), low alloy high strength steel (Q345), cold rolled steel coil or hot rolled coil or hot-rolled orientation, cold rolled or cold -rolled orientation.
1. Steel Grade and Standard
Chequered steel plate is according to GB/T3277-1991 standard. Among them, the low carbon steel plate of GB/T3277-1991 with thickness less than or equal to 4.5mm, the extra high strength steel plate of GB/T3277-1991 with thickness less than or equal to 10mm belong to its material.
2. Manufacturing Process
The manufacturing process of chequered steel plate usually consists of two stages: hot rolling and cold rolling. After hot rolling, a certain thickness of raw material is put on the cold roller. The pressure between the two rollers presses the steel plate into a predetermined thickness. After cold rolling, the checkered steel plate will be formed.
3. Features and Use
Chequered steel plates are usually used in construction, mechanical structure, automobile, shipbuilding, railway and bridge engineering, bridge, crane and other manufacturing operations.
Chequered steel plate has the advantages of high strength, good toughness, good weldability, uniformity and good plasticity. It also has the advantages of high strength, good toughness, good weldability, uniformity, good plasticity and good wear resistance. It has good seismic performance and is widely used in construction, bridges, tanks and other projects and equipment structures.
4. Characteristic
The chequered steel plate has honeycomb, waved, diamond and so on types. Its characteristics are anti-skid and decoration. The anti-skid effect of chequered steel plate can reduce the transportation cost and manual labor cost, improve the transportation efficiency and reduce the cost of vehicle installation and tires.
Conclusion
In conclusion, chequered steel plate is a kind of structure steel produced by hot rolling and cold rolling. It has the advantages of high strength, good toughness, good weldability, uniformity and good plasticity. It is widely used in construction, bridges, tanks and other projects and equipment structures due to its good seismic performance. The chequered steel plate has a honeycomb, waved, diamond and other types, with the characteristics of anti-skid and decoration.
