Steel Drainage GratesHigher security and firmness
 
We use machine pressure welding
and high-voltage resistance
pressure welding machine. The
manipulator automatically places the
crossbar on the flat steel which is
arranged evenly. Through strong
electric welding power and
hydraulic pressure, we can press
the crossbar into the flat steel,
so that we can get the high-quality
steel grading with strong welding point,
stability and high strength.
