The welding methods for pressure-welded steel grating include manual welding and large-scale pressure machine welding.
1 Manual welding involves using spot welders to weld and secure the grating material arranged according to the mold. Generally, the cost is low. The welds are quite sturdy.
2 Machine welding involves using a high-voltage resistance welding robot to automatically place the crossbar horizontally on evenly arranged flat steel bars, then pressing the crossbar into the flat steel with strong welding power and hydraulic pressure. This process adds an extra step compared to manual welding, and a large-scale pressure welding machine can cost several tens of thousands of dollars, making the cost relatively high. The appearance is aesthetically pleasing, but it's not very sturdy. As a result, most people opt for manual welding.
Example of pressure-welded steel grating:
1. Overload hot-dip galvanized steel grating is a hot-dip galvanized grating panel formed by welding flat steel with widths of 65mm to 200mm and thicknesses of 5mm to 20mm. It is suitable for large cargo yards, docks, coal mines, road bridges, etc., and can bear the passage of large trucks.
2. Hot-Dip Galvanized Steel Grating (Bar Spacing 40mm) - The hot-dip galvanized grating with a bar spacing of 40mm is an economical and lightweight option. It is an ideal choice for applications with smaller spans.
3. Hot-Dip Galvanized Steel Grating (60mm Spacing of Flats) - The hot-dip galvanized grating with 60mm spacing of flats and 50mm spacing of crossbars is suitable for the mining industry, solving the problem of mineral splashes on the surface of the panels. Commonly used in processing factories within the mining industry.
4. Hot-Dipped Galvanized Steel Grating (Slit Spacing 30mm) - The hot-dipped galvanized grating with a slit spacing of 30mm is a widely used variety in industrial applications. Within the series of commonly used hot-dipped galvanized gratings, it exhibits strong resistance to surface impact.
5. Hot-dip galvanized steel grating (I-shaped flat steel) is a hot-dip galvanized grating panel made by welding I-shaped flat steel together. It features lightweight and high load-bearing capacity. Press-welded grating panels are suitable for various applications, especially for walkways and visiting platforms.
