Carbon Steel Heavy Duty Metal Grating 40x5mm Electric Galvanizing

Checked Hot Dip Galvanizing Anti-Skid Welded Steel Grating

Welded Steel Grating Introduction

Galvanized steel grid, also known as hot galvanized steel grid, is produced after the steel grid, rust prevention treatment.
There are two kinds of hot dip galvanizing and electric galvanizing.
Hot dip galvanized steel grid according to the manufacturing process, divided into pressure welding hot dip galvanized steel grid and pressure lock hot dip galvanized steel grid;
According to the surface shape of hot dip galvanized steel grating plate, it is divided into toothed hot dip galvanized steel grating plate, flat hot dip galvanized steel grating plate, I hot dip galvanized steel grating plate and compound hot dip galvanized steel grating plate.
The letter "G" may be omitted from the hot dip galvanizing mark of the steel grating.
Hot dip galvanizing implementation standard: GB/T 13912-2002

Welded Steel Grating Application:

Grille is widely used in petrochemical, electric power, tap water, sewage treatment, port, wharf, building decoration, shipbuilding, self-propelled parking lot, municipal engineering, sanitation engineering and other fields platform, walkway, trestle, trench cover, manhole cover, ladder, fence and so on.
After installation, it cannot be moved horizontally or separated from the supporting frame.
Generally speaking, steel grates are installed in two welding devices;
B. Install splint and welding. If it is not removed and moved after installation, it is recommended to install steel grid plate.

Welded Steel Grating Advantages:

1, hot dip galvanized steel grating plate (flat steel spacing 30mm) flat steel spacing 30mm hot dip galvanized steel grating plate is the most widely used varieties in the industrial field.
In the series of commonly used hot dip galvanized steel grates, it has the strongest resistance to surface impact.
The hot dip galvanized steel grid is made of flat steel with width of 65mm - 200mm and thickness of 5mm - 20mm. It is suitable for large cargo yards, docks, coal mines, roads, Bridges, etc., and can carry large trucks through.
2, hot dip galvanized steel grating plate (flat steel spacing 40mm) flat steel spacing 40mm hot dip galvanized steel grating plate is the most economic, the most portable varieties.
In the context of small span, it is the most ideal choice.
Suitable for all kinds of occasions, especially the walkway, sightseeing platform, etc.
3, hot dip galvanized steel grating plate (flat steel spacing 60mm) flat steel spacing 60mm bar for 50mm hot dip galvanized steel grating plate is suitable for mining and mining to solve the problem of mineral splashing on the surface of the plate, often designated for mining processing plants.

Welded Steel Grating Process:

(1) steel bar, steel processing
During construction, the steel bars and sections of the required steel grille are cut out according to the size of the material list and drawings.
Adjust the steel processing shape of the main bar according to the platform and steel grille mold.
② Welding molding
The steel grille steel frame is processed manually on the top and ground of the foundation pit. Before processing, 1:1 lofting is carried out on the level ground.
After lofting is completed, punch holes in accordance with the lofting position and embed reinforcing bars in the holes to expose the ground 5 ~ 8cm.
Assemble the parts of the welded grille according to the requirements, and the end section steel must be fastened with the connecting bolts to the steel plate holes to ensure the accuracy of the connecting holes of the parts of the steel grille.
After the parts of the steel grid are initially welded and fixed in the mold, the parts of the steel grid are taken out evenly and symmetrically from the mold to avoid the distortion of the steel grid.
According to the welding requirements (the welding of steel bar and Angle steel shall be double-sided welding, and the welding length shall be 5D (D is the diameter of welded steel bar);
The height of the welding seam is 0.3d, and the Angle steel is connected with M20 ordinary bolt). The welding shall be symmetrical to reduce stress and deformation.

Welded Steel Grating installation:

The connection mode of steel grid plate is fixed and installed with buckle connector, which is composed of three parts.
