WELDED WIRE MESH
The
production process in this section begins with the cold rolling hot rolled wire
rod supplied by Saudi Iron Steel Company. Realizing that cold rolling may affect
the properties of the wire, the specification of rolling
machines were carefully
put to guarantee that the quality of cold rolled wire does meet Saudi and
International Standards.
The cold rolled wire is then
interred into a fully automatic wire mesh machine, which uses spot welding
methodology, to produce the wire mesh.
