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.
