(2) hot rolled sheet in coil: specification 2.0mm-15.5mm;
Material: q235, ss400, sphc, 16mn, 16mnr, 20g, 65mn.
(3) medium plate: specification 8.0mm-100mm; material q235, 65mn, 16mnl.
(4) galvanized sheet: specification 0.4mm-3.0mm
(5) stainless steel sheet: specification 0.3mm-2.0mm; material 304, 316, 321, 430.
Steel grid plate generally use the carbon steel production, hot-dip galvanizing appearance, can play a role in preventing oxidation. Production of stainless steel can also be used. Steel grid plate with ventilation, lighting, cooling, anti-skid and anti-explosive properties.
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.

The lower limit of C content may not be required upon agreement between the supplier and the buyer and indicated in the contract. For steel plates with a thickness greater than 60mm, the upper limit of carbon content can be increased to 0.22%.
According to the requirements of the buyer, the carbon equivalent can be specified, and the value shall be agreed by both parties. Carbon equivalent calculation CEV(%) C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
Total aluminum content.
Trace amounts of niobium, vanadium, and titanium may be added to the steel, and their content should be filled in the quality certificate, and the total content should not exceed 0.050%.
The content of chromium, nickel and copper as residual elements should not exceed 0.30%, and the content of molybdenum should not exceed 0.080%, and the total content of these elements should not exceed 0.70%. If the supplier can guarantee, the analysis may not be carried out.
