Series of steel gratings for different purposes: Series 1 (pitch 30mm) steel grating is the most commonly used type, and it is used in various industrial fields. The distance between the center of the steel plate of this series is 30mm, which meets the American standard. It is stipulated that the entire steel grating series has the strongest resistance to surface impact. It is widely used in power plants, refineries, sewage treatment plants, granaries, chemical plants, roads, airports and terminals, walkways and gutter covers, stair steps, etc. The toothed steel grating can be used in wet and slippery places, especially for offshore oil platforms. Series 2 (40mm pitch) steel grating is the most economical and lightest type, conforming to the British standard for fixed platforms, walkway and stair specifications. This is the ideal product for small spans, even in transport equipment walkways. Under such load, it is no exception. It can also be used as warehouse shelves, pavilion panels, trestles, protective fences, sun curtains, etc. Series 3 (60mm pitch) steel gratings are specially developed for the mining industry and solve the problem of mineral splashing on the board. This series of steel gratings has a nominal size of 50*60mm, allowing most of the splashing material to fall through, thus ensuring the cleanliness and safety of the board. This product is often specified for use in the surface of the crushing system. , walkways on the conveyor line, ball mills, processing plants and operation stations. As a new type of engineering material, steel grating is mainly used as a platform, bridge, bridge, highway guardrail, trench cover, fence, gate and other facilities in the fields of metallurgy, energy, shipbuilding, municipal, petrochemical, transportation, building materials and national defense. At present, China needs about 270,000 tons of steel gratings annually. Therefore, the market prospect of steel grating is very broad.
