Cold rolled sections are produced at Montanstahl by forming round wire rod, which can have a max. diameter of 1”, by a continuous rolling process without heating up the material.
Cold rolling is a very efficient manufacturing process which has been developed mainly for small sections. Compared to hot rolling, cold rolling offers some considerable advantages. Excellent surface finish, tight tolerances and the possibility to produce very small production lots are the most obvious. Cold rolling provides the ability to change the mechanical properties of the material and produces certain useful combinations of hardness, strength, stiffness and ductility. This is completed by selective annealing.
