Bending - Import export

Punto Curvatura adopts a technological solution to bend those profiles that have already been through the powder coating treatment, particularly wooden-paint sublimates.

The process of three-dimensional curving of aluminium, stainless steel, brass or iron profiles is carried out in two steps: torsion and bending. This is a very complex process, which only a high-skilled staff, with a technological equipment, can carry out.

The demand of aluminium profiles to furnish the HoReCa industry as well as Department Stores with particular sizes and shapes has considerably increased over the last years. The calendering of profiles used in the construction or in the realization of the most modern refrigerated showcases for cafés, ice-cream parlours or restaurants requires special attention for the aesthetics of the profile.

For the installation on roofs and warehouses, Punto Curvatura realizes the curvature of the substructures of aluminium profiles used for photovoltaic systems.

Punto Curvatura is capable, with special cylinders installed on the bending machines, to comply with the most complex curvature requirements for the realization of tensile structures used to cover circuses, military hangars, museums, exhibition stands, gazebos, stages and agricultural structures.

Together with the curving of single or double sunshade systems, Punto Curvatura is capable to twist them to meet the different architectural requirements.

The curve of the aluminum profile used for mobile walls is made with a sophisticated soft curving of the profile, which makes the curve with straight ends to the two sides of the extrusion. The service is performed by means of laser pointing installed on the bending machines.

The bending of aluminum profiles used in curtain wall systems is carried out with a patented system by filling with a special alloy. During this process, the cross section is not only calendered with millimetric precision, but it also meets all the perpendicular tolerances, avoiding any kind of deformity deflection or "twisted effect", thus maintaining the perfect geometry required.

The staff of Alaia Serramenti srl also includes a team specialized exclusively in cutting and bending sheet metal. These operations, fundamental in the engineering and metalworking industry, allow us to obtain shapes and geometries of absolute precision and customized down to the smallest detail, depending on the specific application for which they are prepared. The first phase of the process consists of cutting the sheet metal, which is carried out by a specially programmed machine so that pieces of precise dimensions and shapes can be obtained. Bending, the second phase of the process, allows the sheets to be shaped, thus making them more functional for the purpose for which they are modified. Thanks to the latest generation machinery we have at our headquarters in San Cipriano d'Aversa, and the knowledge of our qualified staff, we are able to create sheets of metal with the shapes you desire, adapting them to your needs.

The twisting or torsion of the extruded aluminium, stainless steel, brass or iron profiles is carried out via a clockwise (or counter clockwise) solicitation of the cross section against its axis. In order to avoid that this twisting jeopardizes the stiffening rib, we use a filling system to help the stretching and the compression of the fibres. We are able to twist up to 9 mt profiles!
