Key points of steel grid welding technology
At each intersection of the load flat steel and the bar, it shall be fixed by welding, riveting or pressure locking.2, steel grid welding preferred to choose pressure resistance welding, can also choose arc welding.3. The press lock of the steel grid plate can be used to press the transverse bar into the load flat steel and fix it.4, steel plate should be based on the needs of users, processed into a variety of sizes of the shape.
The steel grid plate is made of flat steel in accordance with a certain distance and bar (twisted square steel, square steel, round steel, flat steel, etc.) for interpenetration and placement, and welded into a kind of finished steel with square grid in the center. The steel grid plate is mainly used to make the ditch cover plate, the steel structure channel plate, the stepping plate of the steel ladder, etc.The bar is usually made of twisted square steel.The steel grid is usually made of carbon steel, and its surface is hot dip galvanized, which can prevent oxidation.Can also choose stainless steel manufacturing.The steel grid has the functions of ventilation, lighting, heat dissipation, anti-skid and explosion proof.
Using steel case board installation clip for installation of steel case board with does not destroy the characteristics of the coating, generally applicable to the often need to remove the steel plate used above, each steel plate to be used at least four installation clip, each corner a, for the steel plate with larger area should guarantee per square meter of steel case board installation amount shall not be less than 4.The steel grid plate mounting clamp is divided into three parts: upper clamp, lower clamp and fastening bolt.
