Well cover, also known as steel grating steel grating, also known as grating, call each region vary. Speaking of steel grating manufacturing process is not difficult, is arranged and welded steel, with galvanizing late, so the price is not very expensive, very wide application range. Pressure welding steel grating is the load flat steel and bars with certain distances, using 200 tons of hydraulic resistance welding automation equipment welded into the original plate, after cutting, opening, edging and other processes from customer requirements. Loaded flat pitch: two adjacent bearing bars by the center distance, often 30mm, 40mm two kinds. Bar spacing: distance between the centers of two adjacent rails is usually 50mm, 100mm, two types, according to customer requirements. Compared with the tread plate and other grille, steel grating has the following advantages: saving materials: withstand the same way most provinces material loading conditions and, accordingly, can reduce material support structure. Reduce investment: saving materials, the provincial labor, the provincial period, free cleaning and maintenance. Construction is simple: In the pre-installed support clamp with bolts or welded and fixed, one person to complete. Save period: Products without on-site reprocessing, installation is very quick. Durable: factory corrosion protection by hot-dip zinc, impact resistance ability and weight. Modern style: beautiful shape, design specifications, air and light, giving the overall sleek, contemporary feel. Light structure: a small timber, light structure, and easy lifting. Against product contamination: no accumulation of rain, snow and dust. Reduce wind resistance: Due to good ventilation, windy wind resistance and reduce wind damage. Design is simple: no small support beam, simple structure, designed to simplify; no detail design of steel lattice panels, can only indicate the type, the factory and customers can design discharge plate Fig. Good ventilation, lighting, cooling, explosion, skid resistance: acid corrosion: in the range of PH 6 to PH 12.5, zinc layer surface to form a stable protective film, good corrosion resistance.
