The special feature of the WST profile rolling mill in comparison with the WSN and WN types is the additional adjustability of the rolls in the axial direction. Each roll can thus be adjusted radially and axially.
This special flexibility allows the WST type profile rolling mill to produce wire with a rectangular or square cross section using only one standardized set of rolls. This saves the time, the cost and the labor required to change the rolls for the desired wire profile. All dimensions of wire can be produced immediately.
The WST type rolling mills have extremely low maintenance requirements. All components are protected from corrosion by galvanization.
