Steel profile finishing
Accurate and precise checking of profiles before delivery to the customer
This manufacturing stage includes cutting to size, flattening, straightening and packaging the profiles.
The bars are cut to size and straightened to achieve the bending strain and torsion parameters required by the customer. At Calvi we have 8 roller straighteners, 2 manual straightening presses and 4 automatic straighteners.
These machines, combined with the skills and experience of our qualified technicians, allow us to meet even the most challenging straightness requirements, up to maximum 0.1 mm/m.
A tensile straightening machine with a pulling force of up to 350 tons completes the department. The bars are clamped between the vices of a fixed head and those of an axially moving head that can also rotate, to correct any twisting of the bar.
Tensile straightening removes any undulations on the bar. Another result is better distribution of residual stress because if its values on complex geometries are high, it could be unpredictably released during subsequent manufacturing on the drawn profile.
The finished material is collected in strapped bundles, in crates or on pallets, depending on the customer’s requirements, and then prepared for shipment by land, sea or air.
