Definition of welding steel grating

Welding steel grating is beautiful and practical, and can meet the load requirements under different conditions, making it better than other products with the same purpose. In recent years, they have been more and more widely used. Loaded flat steel and crossbars (twisted square steel, square steel, round steel, flat steel, etc.) are arranged at a certain interval of warp and weft, and welded on a high-voltage resistance welder to form the original plate, which is cut, cut, cut, and hemmed And other processes are processed into finished products required by customers. It is mainly used for gutter cover plates, steel structure platform plates, step plates for steel ladders, etc.

Types of welding steel grating

According to the surface shape, they are divided into tooth-shaped welding steel grating, flat welding steel grating, type I welding steel grating, and composite welding steel grating. According to the surface treatment, welding steel grating plate can be divided into hot-dip galvanized welding steel grating plate, spray-painted welding steel grating plate, and original welding steel grating plate.

Features of welding steel grating

1.Beautiful appearance: simple lines, silver appearance, modern trend.

2.Best drainage: more than twice as much as cast iron rafters.

3.Hot-dip galvanized: strong anti-rust, maintenance-free and replacement.

4.Anti-theft design: The cover and frame are hinged, which is anti-theft, safe and easy to open.

5.Save investment: Under heavy-span heavy load, it is cheaper than cast iron and saves the cost of crushing and replacing if stolen.

6.High strength: Its strength and toughness are much higher than those of cast iron. It can be used in large span and heavy load environments such as terminals and airports.

7.Many specifications: meet the needs of different environments, loads, spans, sizes and shapes.

Difference between manual welding and machine welding

Manual welding: The hand-made steel grid is punched in flat steel first, and then the cross bar is spot-welded into the hole. There will be a gap between the cross bar and the flat steel, but each contact point can be welded to achieve flat The equivalent melting connection of steel and twisted steel, so the welding will be stronger and the strength will be improved, but the appearance is not as beautiful as the machine welding!

Machine welding: The machine pressure welding uses a high-voltage resistance pressure welding machine. The manipulator automatically places the crossbar on the flat steel bars that are evenly arranged. The crossbar is pressed into the flat steel bar by powerful electric welding power and hydraulic pressure. The point is strong, but the machine welding is not as strong as manual welding, easy to open welding, but the appearance is beautiful.
