1. Introduction to heavy steel grating:
Heavy steel grating refers to a steel grating with a bearing flat steel width of more than 65mm and a bearing flat steel thickness of more than 6mm. Its cross bar usually adopts flat steel or reinforcement with a diameter of 10mm or 12mm.
2. Application of heavy steel grating:
The heavy-duty steel grating is specially designed and manufactured for heavy-duty occasions. It is suitable for airports, expressways, industrial platforms, ports and wharves and other occasions with special needs.
3. Classification of heavy steel grating:
4. Heavy steel grating can be divided into heavy pressure welded steel grating and heavy pressure locked steel grating according to the production process.
A. Heavy pressure welded steel grating refers to the steel grating with steel bars for cross bars, which is applicable to the occasion of load in one direction.
B. The heavy press lock steel grating refers to the steel grating with flat steel for the cross bar. It is suitable for the occasion of two-way load. However, the cost is much higher than that of the press welded steel grating, and it is not recommended to use it under normal circumstances.
C. According to the surface shape, it can be divided into planar heavy steel grating and toothed heavy steel grating.
In view of the cost factor, we suggest that the plane steel grating should be used in general, and the toothed heavy steel grating should be used in the anti-skid occasions such as offshore drilling platforms.
