Steel grating, also known as steel grating, steel grating, which is arranged in flat cross a certain distance and crossbar, and welded into the middle of an iron and steel products with a square lattice, is mainly used to make the ditch cover, steel platform boards, ladders stepping board. Q235 hot rolled flat steel material using flat steel, twisted rails after the general square steel. Steel grating mainly about the following characteristics: 1: High strength, light structure 2: corrosion resistance, durable 3: appearance, surface shine 4: No plot of dirt, snow does not accumulate, not water, since clean, easy to maintain 5: ventilation, lighting, cooling, slip-proof good 6: easy to install, etc. He dismantle steel grille is widely used in petrochemical, power, water, sewage treatment, port, building modifications, shipbuilding, After the self-propelled parking, municipal engineering, environmental engineering and other fields platform, walkway, bridge, ditch cover, covers, ladders, fences, etc. an ordinary hot-dip galvanized flat steel grating plate bearing grooving crossbar pressed flat Gang Lock molding. Production of ordinary type grille maximum working height of 100mm. Grating length is usually less than 2000mmm. 2. Integral galvanized flat grill plate bearing Gang Gang and crossbar flat with the same height as the bearer flat notch depth outline of 1/2. Grating height of not more than 100mm. Grating length is usually less than 2000mm. 3, shade-type galvanized flat steel grating carrying open 30 ° or 45 ° chute, slotted flat steel pressure tank lever lock molding. Depending on the need to hand over the other spacing, size grill plate, you can use ordinary carbon Gang, stainless steel, aluminum and other materials. Grating height less than 100mm. 4, heavy duty galvanized grating by high flat rail flat Gang Gang and bite each other at 1200 tons of pressure compression molding. Applicable to span high load bearing applications.
