What is the production process of steel grating and its pressure welding method

Many manufacturers now produce steel gratings, and steel grating products are widely used in our society. It is to arrange square steel and flat steel in a certain order. Thus, it is processed into a rectangular plate on the surface. This kind of plate is widely used and can be used in many aspects of construction. The entire production process is CNC, and the production is simple and convenient.
The pressure welding method of steel grating is simple and fast, mainly manual and machine. Manual pressure welding means: punch holes in the flat steel in advance, and then put the cross bar into the hole for spot welding. The steel grating welded by manual pressure welding is very strong because each contact point between the cross bar and the flat steel can be welded. , but it will cause a gap between the cross bar and the flat steel, resulting in an appearance that is not very beautiful. Machine pressure welding means: the entire pressure welding process is completed by a high-voltage resistance pressure welding machine. The steel grating produced in this way is very beautiful, and there are no exposed welding points on the surface. Most of them are still machine pressure welding.
