PRODUCT DESCRIPTION

The main categories of steel grating: stainless steel grating, platform steel grating, gutter cover, steel grating, composite steel grating, plug-in steel grating, glass fiber reinforced plastic grating, steel grating ceiling, butt-plug steel grating Grid (also known as pressure-locked steel grating), checkered steel grating.

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

Steel grating surface treatment: hot-dip galvanizing, cold galvanizing, painting, dipping in anti-rust oil, dipping in plastic, no treatment.

Steel structure of steel grating: The steel grating is formed by the load flat steel and the cross bars arranged at a certain distance in the warp and weft direction. The warp direction is the load flat steel, that is, the length direction of the steel grating; The width direction of the grid.

Steel grating welding attention

1. At each intersection of the load flat bar and the cross bar

where it should be fixed by welding, riveting or press locking.

2. Pressure resistance welding is preferred for the welding of steel gratings, and arc welding can also be used.

3. The pressure lock of the steel grating can be fixed by pressing the cross bar into the load flat steel by a press.

4. The steel grating should be processed into various sizes and shapes according to the needs of users.

5. The spacing of the load flat steel and the spacing of the cross bars can be determined by the supply and demand side according to the design requirements. For industrial platforms, it is recommended that the distance between the loaded flat bars should not be greater than 40mm, and the distance between the cross bars should not be greater than 165mm.

At the end of the load flat steel, the flat steel of the same specification as the load flat steel should be used for hemming. In special occasions, the section steel can be used or the edge plate can be directly wrapped, but the cross-sectional area of the wrapping plate shall not be smaller than that of the loaded flat steel. The edging adopts single-sided fillet welding with a welding height not less than the thickness of the loaded flat steel, and the length of the weld shall not be less than 4 times the thickness of the loaded flat steel. In the case that the edging plate does not bear the load, it is allowed to weld 4 loaded flat steels at one place, but the distance shall not be greater than 180mm. When the edging plate is under load, interval welding is not allowed and must be fully welded. The end plates of stair treads must be fully welded on one side. The edging plate in the same direction as the load flat steel must be welded with each cross bar. The incisions and openings in the steel grating are equal to or larger than 180mm, and should be treated with hemming. If the stair tread has a front edge wrap, it must run through the entire tread. The load flat steel of the steel grating can be flat flat steel, I-shaped flat steel or slitting strip steel. The load flat steel of the steel grating can have a tooth profile to increase the anti-slip force of the steel grating. The tooth profile size is shown in Figure 2. Not less than 5 teeth per 100mm. The minimum width of the steel grating on the tooth size platform shall not be less than 300mm.

The main purpose of steel grating: steel grating is suitable for alloys, building materials, power stations, boilers. shipbuilding. For petrochemical, chemical and general industrial plants, municipal construction and other industries, it has the advantages of ventilation and light transmission, anti-skid, strong bearing capacity, beautiful and durable, easy to clean and easy to install. Steel grating has been widely used in all walks of life at home and abroad, mainly used as industrial platforms, ladder treads, handrails, passage floors, railway bridge sideways, high-altitude tower platforms, drain covers, well covers, road grilles, three-dimensional It can also be used as a fence for parking lots, institutions, schools, factories, enterprises, sports fields, and garden villas.
