product technology
The production of steel grid plate mainly has two kinds of machine pressure welding and manual production. Machine pressure welding using high voltage resistance pressure welding machine, through strong electric welding power and liquid pressure to press the transverse rod into the flat steel, to ensure that the solder joint is strong, stable and strong. Handmade, on the other hand, is relatively flexible and suitable for various special needs.
