1, flat steel and bars are made of Q235 manufacture GB / T700, and according to the agreement between the drilling platform steel grating production, but also use other materials. 2, the use of hot-rolled flat steel or flat after slitting of hot-rolled or cold-rolled strip. 3, flat dimension tolerances specified in Table A YB / T4001.1-2007 of. 4. The use of hot-rolled flat steel flat tooth or after slitting hot-rolled or cold-rolled strip and punch teeth. Tooth size can not be less than five teeth in each 100mm. 5, I-shaped cross-sectional dimensions of flat steel and moment of inertia. Platform steel grating can be used with different specifications of steel lattice-board flat steel flat steel edging, or angle, channel, square tube, etc. Hemming. Platform steel grating can be mounted handles and hinges in need often move or open steel grid plate. Hemming welding standards platform steel grating: Series 1 every five welds; Series 2 every four welds; Series 3 every three welds. Weld is not less than 3mm sided fillet weld, the weld length 20mm. Platform steel grating is a very broad application of steel grating products, also known as hot-dip galvanized steel grating platform, using different specifications and load flat steel flat steel edging, it has a better rig carrying capacity Grating much money, and the surface after a hot galvanized, electro-galvanized and other treatment processes, making it more shiny bright surface, better corrosion resistance, the use of more durable, can live up to 30 years. Anping drilling platform steel grating, steel grating hair million (certified), drilling platform steel grating made by Anping million steel grid MILL. Anping send one hundred million steel grid MILL (www.hbggb.net) (www.hbggb.net) Hebei Hengshui, the wire mesh of the leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum limits to meet customer needs. Steel grating sent one hundred million in leadership with the staff warmly welcome all inquiries negotiations to create hair one hundred million steel grating a better future.
