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.Sales
