I also called work steel grating steel grating, mainly to select different types of flat steel. I steel grating from I-flat (flat on both sides of the thick middle thin) and twist steel (also called twisted steel, square steel generally 5 * 5,6 * 6,8 * 8, twisted steel) arranged according to a certain latitude and longitude grid spacing, the type I to load flat steel, which galvanized steel grating in the longitudinal direction; zonal for rail, namely the width direction of the steel grating. I steel grating specifications: 1, generally made of high quality steel grating or flat hot-rolled strip, twist steel, carbon steel and stainless steel, hot dip galvanized appearance, can serve to prevent oxidation. 2, in the flat steel and bars at every intersection, will be fixed by welding. 3, the pitch spacing and load flat steel rail can be determined according to the design requirements of supply and demand side. For industrial platform, the proposed flat load spacing not greater than 40mm, bar spacing not greater than 165mm. 4, steel grating load flat steel, can be flat plane, I type flat or slitting strip. 5, our company according to the user's needs, the processing of steel grating into the shape of various sizes. Uses and Features: I do use a steel grid moderators drain cover, steel platform board, ladders treads, also widely used in petrochemical, power plants, water plants, sewage treatment plants, municipal engineering, sanitation platform engineering and other areas, walkways, covered trestle ditch, covers, ladders, fences, fence, etc. I steel grating with ventilation, lighting, cooling, slip-proof properties. Compared with the flat steel grid, the word most steel grating with a light weight, more economical and practical features.
