The steel grating plate is formed by crosswise arranging bearing bars and cross bars (twisted square steel, twist steel, flat steel and so on) at certain intervals, performing orthogonal combined welding or pressure locking for fixing to form a steel member with square gratings in the middle, and performing deep processing through processes of cutting, tapping, edge covering and so on and meets the requirement of customers.
The steel grating plate is mainly used for manufacturing steel structure passage platforms, step plates of steel ladders, various trench covers and so on, and is roughly classified into a pressure-welded steel grating plate manufactured by welding flat steel and cross bars through a pressure resistance welding machine, and a pressure-locked steel grating plate manufactured by transversely and longitudinally welding flat steel according to manufacturing methods. The finished steel grating plate can be prevented from being oxidized through hot galvanizing generally. The steel grating plate also can be made of stainless steel. The using amount of the steel is saved most under the same load condition, and the material of a supporting structure can be correspondingly reduced. Expense is saved, and the mounting process is simplified. Rain water, ice, snow and dust are not accumulated, and the steel grating plate is not required to be cleaned or maintained, and is widely applied to many projects in China.

Steel Gratings
1. Pressure welding Grille Flat steel: The material is Q235A or stainless steel, there are ordinary plane type, non-slip tooth type and section I type. Common specifications are 20*5, 25*5, 25*3, 32*5, 32*5, 40*5, 40*3, 50*5, 65*5, 75*6, 100*8, 100*10 Wait. 2. Pressure welding Grille Crossbar: Round steel, twisted square steel, square steel or hexagonal steel made of Q235A or 304 stainless steel. Twisted square steel is made by drawing and twisting the coil through a square die. Its common specifications are 5*5, 6*6, 8*8mm, etc.
Steel Grating It is steel bar according to a certain distance and cross arranged and welded into the middle of a square latice with an iron and steel products . bearing bar 25/3mm , 25mm/4mm , 25mm/5mm , 30/3mm , 30/5mm,32/3mm,32/5mm ,40/3mm75/5mm,100/10mm opening 30mm x 32mm , 30mm x 60mm, 30mm x 100mm , 38mm x 100mm , 40mm x 100mm , 50mm x 50mm ,50mm x 100mm etc surface treatment black , hot dip galvanized type plain bar, serrated bar , I shape bar Hot dip galvanized steel grating tolerance The allowed deviation of length is +0/-5mm, while the allowed deviation of width is +/-5 mm. The non-perpendicularity of bearing bar is allowed no more than 10% of width of bearing bar. Cross bar surface should not surpass bearing bar surface 1mm, beginning & end of cross bar should not surpass the end surfaces of two sides of grating 2mm. Features Corrosion resistance, Rust resistance. Anti-slip resistance, Good air circulation. Good drainage performance, Easy to install and uninstall. High strength-to-weight performance,Durable and long lifespan. Applications Steel grating is widely used for work platforms. Catwalks, transportation servicing areas and vehicle steps.
