main categories
Classification according to the shape of flat steel: flat steel
grid plate, tooth flat steel grid plate, I flat steel grid plate,
etc.
According to the form of the bar classification: twisted square
steel bar steel grid plate, round steel bar steel grid plate, flat
steel bar steel grid plate.
Classified by surface treatment: hot-dip galvanized steel grid,
cold galvanized steel grid, spray painted steel grid, etc. Hot-dip
galvanized steel grid plate has strong impact resistance and
corrosion resistance. The cost of cold galvanized steel grid is
relatively low, but the rust prevention ability is medium; The
color of the painted steel grid is diverse, but the anti-rust
ability is weak and afraid of wear.
Classification by use: platform steel grid plate, ditch cover plate
steel grid plate, stair step plate steel grid plate, etc. These
steel grids are designed according to specific application
scenarios to meet different load bearing, anti-slip, drainage and
other requirements.
According to the welding method and other categories: pressure
welding type, insert type, lock type and weld type. In addition,
there are stainless steel grid plate and carbon steel grid plate,
according to the different material, its corrosion resistance,
strength and other properties are also different.

Product material diversity
Raw materials of steel grid plate are: flat steel, twist steel,
pattern plate.
The steel grid plate is an open steel member which is composed of
bearing flat steel and cross bar according to certain spacing and
fixed by welding or pressure lock. The transverse bar is generally
made of twisted square steel, round steel or flat steel, and the
material is divided into carbon steel and stainless steel.
Production method of steel grid plate:
The pressure welded steel grid plate is made of load flat steel and
cross bar arranged according to certain spacing longitude and
latitude, using 200 tons of hydraulic resistance welding automatic
equipment to weld into the original plate, through cutting,
opening, packaging and other processes.
Load flat steel spacing: the center distance between two adjacent
load flat steel, commonly used 30MM, 40MM two.
Bar spacing: The center spacing of two adjacent bars is usually
50MM and 100MM.
