What is Special-shaped steel gratings

Special-shaped steel gratings are made of various irregular-shaped steel gratings according to the actual needs of customers, mainly including corner cutting, hole cutting, arc cutting, fan-shaped, etc., so as to avoid secondary cutting processing when the goods arrive at the construction site, thus It makes the construction and installation faster and simpler, and also avoids the damage of the galvanized layer caused by on-site cutting.

Basic situation

Special-shaped steel gratings are made of various irregular-shaped steel gratings according to the actual needs of customers, mainly including corner cutting, hole cutting, arc cutting, fan-shaped, etc., so as to avoid secondary cutting processing when the goods arrive at the construction site, thus It makes the construction and installation faster and simpler, and also avoids the damage of the galvanized layer caused by on-site cutting.

The special-shaped steel grating is relative to the rectangular steel grating.

The characteristics are: the assembly is circular, trapezoidal, semicircular, fan-shaped, and the strong grid welding makes it have the characteristics of high load capacity, light structure, and easy hoisting; the appearance is beautiful and durable. Can be customized according to user requirements, design and install on behalf of customers.

Production method;

There are two types of machine welding and manual welding: machine welding uses a 200-ton hydraulic resistance welding automatic pressure welding machine, and the manipulator automatically places the crossbar on the evenly arranged flat steel, and uses strong electric welding power and hydraulic pressure to press the crossbar. Press-welded into the flat steel, so that high-quality steel grating products with strong solder joints, high stability and strength can be obtained. The hand-made steel grating is first punched on the flat steel, and then the cross bar is put into the hole In spot welding, there will be gaps between the cross bar and the flat steel, but each contact point can be welded to achieve the equivalent melting connection of the flat steel and the twisted steel, so the welding will be stronger and the strength will be improved, but the appearance is not as good as that of the pressed steel. Beautiful welding!

Application field

Steel grating is suitable for alloys, building materials, power stations, boilers. shipbuilding. Petrochemical, chemical and general industrial plants, municipal construction and other industries have the advantages of ventilation and light transmission, non-slip, strong bearing capacity, beautiful and durable, easy to clean, and easy to install. Steel grating has been widely used in various industries at home and abroad, mainly used as industrial platforms, ladder pedals, handrails, passage floors, railway bridge sideways, high-altitude tower platforms, drainage ditch covers, manhole covers, road barriers, three-dimensional Parking lots, schools, factories, sports grounds, fences for garden villas, can also be used as exterior windows of houses, balcony guardrails, guardrails for highways, railways, etc.
