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

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.
(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.
