Steel grating, also known as steel grating, steel grating, which is arranged in flat cross a certain distance and crossbar, and welded into the middle of an iron and steel products with a square lattice, is mainly used to make the ditch cover, steel platform boards, ladders stepping board. Q235 hot rolled flat steel material using flat steel, twisted rails after the general square steel. Features Type Features steel grating steel grating are mainly about the following characteristics: 1: High strength, light structure 2: corrosion resistance, durable 3: appearance, surface shine 4: No plot of dirt, not plot rain snow, not water, self-cleaning, easy to maintain 5: ventilation, lighting, cooling, slip-proof good 6: easy to install, etc. and he dismantle steel grille classification mainly come from the following points: (1) by welding, can be divided into: bonding type, phase embedded type, wear and wear welding locking type (2) by its flat side surface shape of the load can be divided into: flat type, tooth type and the "workers" font, etc. (3) can be divided according to their use: general purpose steel grating steel grille and special purpose such as: trench cover, treads and so on. (4) steel grille divided by material: Use stainless steel grille and carbon steel grating steel grating steel grating is widely used in petrochemical, power, water, sewage treatment, port, building modifications, shipbuilding self-propelled car park, municipal engineering, environmental engineering and other fields platform, walkway, bridge, ditch cover, covers, ladders, fences, etc.
