根据客户需求

Special-shaped steel gratings are made according to the actual needs of customers. Various irregular-shaped steel gratings are produced, mainly including corner cutting, hole cutting, arc cutting, sector shape, etc., thus avoiding the need for secondary cutting when the goods arrive at the construction site, thus It makes construction and installation faster and simpler, and also avoids damage to the galvanized layer caused by on-site cutting. Special-shaped steel grating is relative to rectangular steel grating.
Features: It is assembled into circular, trapezoidal, semicircular, and fan-shaped shapes [] The firm grid welding makes it have high load-bearing capacity, light structure, and is easy to hoist. It has the characteristics of beautiful appearance and durability. It can be customized according to user requirements and designed and installed on behalf of customers.
There are two types of machine welding: machine pressure welding and hand-made. Machine welding uses a ton hydraulic resistance welding automatic pressure welding machine. The robot automatically places the crossbar horizontally on the evenly arranged flat steel, and uses powerful welding power and hydraulic pressure to The cross bars are pressure welded into the flat steel, so that a high-quality finished steel grating with strong welding joints, extremely high stability and strength can be obtained. The hand-made steel grating is first punched in the flat steel, and then the cross bars are placed For spot welding in the hole, there will be a gap between the crossbar and the flat steel, but every contact point can be welded to achieve the same melted connection between the flat steel and the twist steel, so the welding will be stronger and the strength will be improved, but the appearance Not as beautiful as pressure welding!
