Steel grille standard steel grille features

Steel grid plates are also common steel grid plates. Steel grid plates are made of flat steel and made of steel grid plates. Many advantages of steel grid plates have been praised by customers. The surface hot-dip galvanizing treatment is not only The service life of the steel grid plate can be prolonged, and the oxidation of the steel grid plate can also be prevented, the appearance is simple, the bearing capacity is large, and different environments can be applied. Let's take a look at the standard of the steel grille.

Steel grille standard

GB700-88 is a carbon structural steel, GBl220-92 is a stainless steel rod, GB3159-83 is a hydraulic universal testing machine, GB4053.2-83 is a fixed steel inclined ladder, and GB4053.4-83 is a fixed industrial steel platform. GB/T13912-92 represents the technical requirements for metal coatings and hot-dip zinc coatings for steel products.

Steel gratings need to be loaded with flat steel and crossbars arranged in a certain degree of latitude and longitude with a certain distance to form a grid. The longitudinal direction is the loading flat steel, and the latitudinal direction is the width direction. The crossbar and load flats need to be fixed at each intersection and can be welded. However, pressure resistance welding is preferred, but arc welding can also be used. If press-lock method is adopted, a press can be used to press the crossbar directly into the load flat steel to achieve a fixed effect.

The load flat steel on the steel grid plate can be flat flat steel, type I flat steel or longitudinal strip steel. If it is used for the platform is the steel grating on the walkway, the minimum width can not be less than 300mm. The spacing between the load flats is recommended to be 30mm, 35mm or 40mm, while the spacing between the crossbars is recommended to be 100mm, 76mm or 50mm.

The allowable deviation of the length and width of the steel grating is ±5mm, and the non-perpendicularity of the load flat steel needs to be less than 10% of the width of the flat steel. The length of the skewed edge of the rail to the center of the steel grating should be less than 5mm, its longitudinal bending deflection should be less than 1/200 of its length, and the transverse bending deflection should exceed 1/100 of its width.

Classification of steel gratings

The classification of steel grille is mainly divided into the following points:

(1) According to the welding method, it can be divided into: pressure welding type, phase inlay type, lock type and wear type

(2) According to the shape of the side surface of the load flat steel, it can be divided into: flat type, tooth type and "work" type, etc.

(3) According to its use, it can be divided into: general purpose steel grids and special purpose steel grids such as: trench covers, treads, etc.

(4) Steel grating is divided into materials: stainless steel grille and carbon steel grille

Steel grille has several characteristics

1, high strength, light structure

2, anti-corrosion ability, durable

3, beautiful appearance, surface gloss

4, no dirt accumulation, no accumulation of rain and snow, no water, self-cleaning, easy to maintain

5, ventilation, lighting, heat dissipation, anti-skid, explosion-proof

6, easy to install him

Summary: The above is the content of steel grille standard and steel grille that Xiaobian introduced for everyone. I hope we can help you effectively. For more information, please pay attention to this website.
