The steel grating is generally made of carbon steel, and the surface is hot-dip galvanized, which can prevent oxidation. It can also be made of stainless steel. The steel grating has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.
 

The steel grating is a kind of steel product with a square grid in the middle that is cross-arranged with flat steel according to a certain spacing and cross bars, and welded by a pressure welding machine or manually to form a square grid in the middle. The steel grating is mainly used as a ditch cover , steel structure platform board, step board of steel ladder, etc. The cross bar is generally made of twisted square steel.

Folding series 1 (30mm spacing)

Steel grating is the most commonly used type and is widely used in various industrial fields. The center distance of the loaded flat steel grating of this series is 30mm, which conforms to the American standard. In the whole steel grating series, it has the most impact on the surface Strong resistance. It is widely used in power plants, refineries, sewage treatment plants, granaries, chemical plants, public steel grating steel grating Platforms such as roads, airports and docks, walkway and gutter covers, stair treads, etc. Among them, the toothed steel grating can be used in wet and slippery places, especially for offshore oil production platforms

Folding Series 2 (Pitch 40mm)

Steel grating is the most economical and lightest type. It meets the specifications of fixed platforms, walkways and stairs stipulated in British standards. It is the most ideal product for small-span occasions, even under the load of transport equipment walkways. In addition, it can also be used as warehouse shelves, pavilion panels, trestles, protective fences, sun curtains, etc.

Folding series 3 (pitch 60mm)

Steel grating is a variety specially developed for the application of mining industry, which solves the problem of mineral splashing on the plate surface. This series of steel gratings has a nominal size of 50*60mm through-hole, which allows most of the splashing materials to pass through, thus ensuring the cleanliness and safety of the plate surface. This product is often specified for the plate surface in the crushing system , the walkway on the conveyor line and the ball mill, the processing plant and the operation station, etc. As a new type of engineering material, steel grating is mainly used as platforms, trestles, bridges, highway guardrails, ditch covers, fences, gates and other facilities in the fields of metallurgy, energy, ships, municipal administration, petrochemicals, transportation, building materials, and national defense. At present, my country's annual demand for steel grating is about 270,000 tons. Therefore, the market prospect of steel grating is very broad.

Steel grating is suitable for alloys, building materials, power stations, boilers. shipbuilding. petrochemical steel grating, chemical and general industrial plants, municipal construction and other industries, with ventilation and light transmission, non-slip, strong bearing capacity, beautiful and durable, easy to clean, easy to install and so on. Steel grating has been widely used in various industries at home and abroad, mainly used as industrial platforms, ladder pedals, handrails, passage floors, railway bridge sideways, high-altitude tower platforms, drainage ditch covers, manhole covers, road barriers, three-dimensional Parking lots, fences of institutions, schools, factories, enterprises, sports grounds, garden villas, can also be used as external windows of houses, balcony guardrails, guardrails of highways and railways, etc.
