The steel grid plate production standards, ChinaYB/T4001-1998;Besides the United States,

Britain, Australia and New Zealand also have their own standards. Accordance with the

standard steelGB700-88,GB1220-92.
     Plate steel lattice-tooth surface to be increased anti-skid performance. Flat steel of

the type I also can be produced flat steel.
    The steel grid plate  production methods: manual machines pressure welding and the

production of two. Pressure welding machines use high pressure resistance pressure welding

machine, manipulator automatically bar cross on the uniform with a flat steel, through a

strong and liquid pressure welding power pressure will be welded into the flat steel bar,

which can be solid solder joint, high stability and strength of high-quality steel grid

plate. Handmade steel grid in the flat steel plate is the first punching and then bar caving

the hole in the spot welding, and the flat steel bar gap exists, but it is impossible to

have every point of contact welding, welding is not strong, and strength decrease.
    Steel grid plate purposes: petrochemicals, municipal engineering, port engineering,

machinery industry, the water plant, steel industry, manufacturing, food processing

industry, and other industries have been widely used.
