Steel grating

Description

Bar grating is made by the world first-class Italian ORSOGRIL equipment .which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance .Cross bar is pressed into the bearing bar by high tension resistance weldingring which is controlled by computer , So we can produce high quality gratings with firm welding , smooth surface and high strength. Classification: Raised (Standard, Regular)and Flattened Surface Process of Gratings ***** , Hot galvanizing will be carried out after end welding process , When the thickness of bearing bars is not less than 5mm, the weight of average Zinc Layer will not be less than **0g/m2 .When the thickness of bearing bars is less then 5mm, the weight of average Zinc Layer will not be less than **0g/m2 . The quailty and requirements after hot galvanizing are subject to the standards of GB/T ****2. ***** gain protection layer through the ways of spraying, brushing and soaking Steel Gratings Most—Poular Specifications ***** grating that the pitch between bearing bars is *0mm, is most widely used type in industrial field . Among normal types , it has the strongest resistance to surface lash. ***** grating that the pitch between bearing bar is *0mm is the most economical and lightest ***** is the best choice for you on occasions that the clear span is small. ***** grating that the pitch between bearing bar is *0mm and the pitch between cross bars is *0mm is developed specially for mining industry , it solves the problem of mineral splash on the plate .So it is often appointed to use in processing works, of mining industry. ***** grating with the pitch of *0mm between bearing bars and of *6mm between corss bars is the most popular type used hone and abroad , it is proper for many applications such as walkways , platforms , etc. Series Pitch of Bearing bar Cross-bar Pitch Specification of bearing bar loadï&frac*4;ˆwidth×thicknessï&frac*4;‰ *0×3 *5×3 *2×3 *0×3 *0×5 *5×5 1 3
