Steel grating is the most common type, use of the product throughout the various industrial fields. This system class by steel grating bearing bars center distance of 30mm, in line with US standards, the entire steel grating series, with the strongest impact on the surface resistance, it is widely used in refineries, power plants, sewage treatment plants, silos, chemical plants, highways, airports and docks and other platforms, walkways and drain cover, stair stepping, etc., which toothed steel grating can be used in wet, slippery places, especially for offshore oil platforms. Stair treads platform steel grating trench cover stainless steel plug-shaped steel grating steel grating composite steel grating 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 board, processed through 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 rail is usually 50mm, 100mm, two kinds, according to customer requirements. Material savings: bear the same way most provinces material loading conditions, and accordingly, can reduce the material of the support structure. Reduce investment: saving materials, the provincial labor, the provincial period, free cleaning and maintenance. Construction is simple: in the pre-installed on the support clamp bolts or welded fixing, one person to complete. Save duration: Products without on-site reprocessing, installation is very quick. Durable: the factory hot-dip zinc corrosion protection, impact resistance and weight of ability. Modern style: appearance, design specifications, air and light, giving the overall sleek, contemporary feel. Lightweight construction: timber less, 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 beam, simple structure, designed to simplify the ventilation, good lighting, cooling, explosion-proof, non-slip performance in accordance with the shape of the surface can be divided into toothed, flat type, type I and type and other complex
