Our purpose; look forward to your visit and sincere cooperation to ensure quality, timely delivery, a cooperative permanent friend. Factory direct factory production cooperation and win-win cooperation earns fees once permanent friends look forward to your visit galvanized surface treatment, cold galvanizing, painting, anti-rust oil dip, dip, not processed. Grid applications in the construction, design and decoration, sewage treatment, engineering and other fields have a wide range of uses. Steel grating production process is generally divided into two production pressure welding machine and hand. Machines use high pressure resistance pressure welding pressure welding, the robot automatically on the flat horizontal crossbar evenly through strong welding power and hydraulic bonding force crossbar into the flat, solder joint can be obtained solid, high stability and strength of high-quality steel grating. handmade steel grating is the first punch in the flat, and then the crossbar into the hole in the spot welding, steel bar and the gap will exist, and each contact point can not be welded, the welding is not strong, the strength decreased. Steel grating mainly about the following characteristics: high strength, light structure *% corrosion resistance, durable ￥ @ no accumulation of dirt, not plot rain and snow, not water, self-cleaning, easy to maintain steel grille huaqirz, ventilation , light steel grille wxxljs, heat, slip-proof, good, * easy to install, demolition and other steel grille wxxljs, Rizhao steel grille (certified), steel grating supplied by Anping Wire Mesh Products Co.
