Steel grating platform: platform steel grating is an application and a wide range of steel grating products, platforms, steel grating generally used in steel or concrete structure on the platform used. It is used for a variety of platforms factories, workshops, mining, port, beautiful style, easy to install, is a new building products. Commonly known as hot dip galvanized steel grating platform is the platform steel grating aisle. Platform steel grating (steel grating) links up and down frequently and steel treads together with use. Steel grating material platform (platform steel grating): 1: flat steel and bars are made of Q235 material manufacturing GB / T700's. Under the agreement, but also use other materials and manufacturing. As used in the boiler Q235 material, used in chemical, offshore dock with stainless 304,316,316L material. 2: Flat hot rolled flat steel or after slitting hot-rolled or cold-rolled strip was 3: Flat size tolerances comply with the national standard steel grating YB / T4001.1-2007 of. 4: hot rolled flat steel flat steel tooth or teeth after slitting punch or hot-rolled cold-rolled strip. Tooth size no less than five teeth in each 100mm. Platform steel grating surface treatment: hot dip galvanized, cold galvanizing, painting, stained rust or not treated surface. Generally use the hot-dip galvanizing, the general use of steel grating galvanized surface after treatment, the corrosion preventive service life of up to 30 years -40 years. Cold galvanizing buyers are often used, but its corrosion resistance is weak, normal rain and sun will inflict serious impact on the natural environment in a year it will rust, zinc coating off. Steel grating platform features: 1: You can increase welding kick plate (wall plate), checker plate shield, install connectors and other peripheral accessories in steel grating. 2: flat steel grid onboard different sizes of flat steel edging, or use angle, channel, square tube, etc. Hemming. 3: You can require frequent moves or open steel grid panel installation platform handles or hinges. 4: In general, Hemming welding standards platform steel grating: Series 1 (flat pitch is 30mm) every five welds, Series 2 (flat pitch 40mm) every four welds, Series 3 (flat pitch 60mm) every three welding one. Weld is not less than 3mm sided fillet weld, the weld length 20mm.
