SPECIAL PROFILES

Calvi SpA produces special cold drawn profiles in all the main types of steel: common, carbon, case hardening, alloy and stainless steels.

Our range is limited only by the restrictions given by the forming properties of the steel itself. Steel is a cost-effective and eco-friendly material due to the fact that its iron and carbon alloy is tensile and hard wearing.

Current forming processes also make it possible to work towards successfully inhibiting the residual stresses released by the material during subsequent processing carried out by the customer.
