Key points of welding technology of metal steel bar grating

Key points of welding technology of metal steel bar grating

• At each intersection of the load flat steel and the transverse bar, it should be fixed by welding, riveting or pressure locking
• The welding of metal steel bar grating is preferred by pressure resistance welding, and arc welding can also be selected
• The compression lock of the metal grating can be fixed by pressing the cross bar into the load flat steel by a press
• The metal grating should be processed into various scales according to the needs of users
• The distance between the flat steel load and the crossbar can be determined based on the planning request of the supply and demand parties. It is recommended that the distance between the flat steel load should not exceed 40mm, and the distance between the crossbars should not exceed 165mm.

What is metal grating

---

The metal grating is a flat steel in accordance with a certain distance and cross bar (twisted square steel, square steel, round steel, flat steel, etc.) interpenetration, and welded into a steel finished product with a square grid center, metal grating is mainly used to make gutter cover plate, steel structure channel plate, steel ladder step plate, etc. The bar is usually made of twisted square steel. The metal grating is usually made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. It can also be made of stainless steel. The metal grating with ventilation, lighting, heat dissipation, anti-slip, explosion-proof and other functions.

At the end of the loaded flat steel, flat steel of the same standard as the loaded flat steel should be used for wrapping. In the special use of the occasion, you can use the shape steel or directly with the guard plate to wrap the edge, but the cross-sectional area of the edge plate shall not be less than the cross-sectional area of the load flat steel.
