Steel grid plate is also known as steel grid plate. The grid plate is a kind of steel product with square grid in the middle, which is cross arranged by flat steel according to a certain distance and cross bar. It is mainly used to make ditch cover plate, steel structure platform plate, step plate of steel ladder, etc. the cross bar generally adopts twisted square steel.




Introduction to grid plate

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

classification

1. According to the welding method, it can be divided into: pressure welding type, phase inlay type, through lock type and through welding type.

According to the shape of the side surface of the load flat steel, it can be divided into plane type, tooth type and "I" shape, etc.

3. According to their uses, they can be divided into general purpose steel grating plate and special purpose steel grating plate, such as trench cover plate, step board, etc.

4. Steel grid plate is divided into stainless steel grid plate and carbon steel grid plate according to material [1].



Production method

1. Pressure welded steel grid plate is a product required by customers by the load flat steel and cross bar arranged by a certain distance, welded into the original plate by 200 tons of hydraulic resistance welding automation equipment, and processed by cutting, opening, edge wrapping and other processes.

2. Load bearing flat steel spacing: the center distance between two adjacent loaded flat steel, commonly used 30mm and 40mm.

3. Cross bar spacing: the center distance between two adjacent cross bars is usually 50 mm, 100, two kinds, which can be produced according to customer requirements.

4. Various types of steel grating can be customized according to customer requirements.



surface treatment

Hot dip galvanizing, cold galvanizing, electro galvanizing, painting, dipping in antirust oil, dipping in plastic, no treatment.

2. Horizontal bar spacing: 50, 100 (mm) in general, 38 and 76 in non-standard spacing;

3. Width: 20-60 (mm);

4. Thickness: 3-50 (mm).



Application editing

It is widely used in petrochemical, electric power, tap water, sewage treatment, port and wharf, building decoration, shipbuilding, self-propelled parking lot, municipal engineering, environmental sanitation engineering and other fields, platform, walkway, trestle, ditch cover, well cover, ladder, fence, factory construction, etc.

The steel grid fence plate is used to replace the guardrail with the steel grid plate. The guardrail is also known as the guardrail net and isolation fence, so the "steel grid substitute" is also known as the steel grid plate. Because of its strong performance compared with guardrail net, so using steel grating to make grid plate is more customized for specific requirements, and is rarely used! The price is 2 times higher than ordinary guardrail [1].



product






Steel grating ceiling



It is designed and manufactured with steel grating. It has the advantages of light structure, beautiful appearance, high strength, easy installation, hot-dip galvanizing on the surface, corrosion resistance and maintenance free. Widely used in tobacco manufacturing, industrial plants, large stadiums, exhibition centers, large commercial, station, wharf, airport and other industrial and civil building ceiling.




Stair step

There are two kinds of step installation: welding and bolt fixing. The surface of the product is treated by hot-dip galvanizing. It is used with Dahe railings. It is beautiful and firm, easy to install and free from maintenance. The manufacturing of steel ladder conforms to gb4053.2-83 standard and the requirements of national general architectural standard design atlas 87j422 (jsjt-90).



Dense steel grating

Dense steel grating refers to the pressure welded steel grating with bearing flat steel spacing less than 25 mm. In addition to the advantages of the standard pressure welded steel grating, such as beautiful form and easy installation, it also meets the requirements of some special occasions for the size of objects passing through or leaking. For example, in civil occasions with large flow of people, dense steel grating can meet the walking requirements of women's high-heeled shoes; for example, in industrial and mining enterprises with large flow of people, it is required not to have large objects (such as straight Steel balls with diameter less than 20 mm are dropped to meet the safety requirements [1].
