Steel grating is made of carbon steel through processing and production, in order to prevent rust, made products need to be hot-dip galvanized process, which is now sold on the market hot-dip galvanized steel grating, can effectively prevent the oxidation of rust caused by external air and other substances. In addition, we can also use stainless steel raw materials to produce steel grating, although the rust-proof effect is good. In addition, in order to prevent the steel grating from rusting, we can also use the paint method to deal with it, spraying anti-rust paint or painting anti-rust paint, through this method to get a protective layer to prevent rusting.
The technical requirements of steel grating are as follows: according to the requirements of the buyer, steel grating can be delivered without wrapped edge. Steel grating wrapped edge is welded with a single-sided angle weld with a height not less than the thickness of the bearing flat steel, and the length of the weld shall not be less than 4 times the thickness of the bearing flat steel. In the case that the grating does not bear the load, the corresponding distance of 4 flat bars is normally welded at one place, but the distance shall not be greater than 150mm. Together with the load-bearing flat steel, the edge plate must be welded with each crossbar.
If the distance welding of steel grating is blocked and the opening exceeds 180mm, it should be wrapped. Welding is a very important part, the quality of welding will directly affect the bearing capacity of steel grating and its time. If the welding is not good or not used for a few days, the grating will not be used. Hot-dip galvanizing is very important for steel grating, which is the surface of steel grating, and the criterion of steel grating is the surface of hot-dip galvanizing. Hot-dip galvanizing is not only beautiful, but also its rust-proof ability. Steel grating equipment clip equipment more quickly, can save a lot of time. Steel grating equipment equipment, will not constitute the steel grating zinc layer and steel structure corrosion layer damage. Easy to dismantle, one wrench can dismantle the steel grating. There is good flexibility.
