Stainless steel is one of the most used materials in the construction industry due to its great versatility. The surface layer of stainless steel can be modified through a series of chemical processes, creating different surface finishes. Already in the preliminary phase, it is possible to define the desired type of finish for the stainless steel.
Hot extrusion is the production process used to form special steel profiles with a constant longitudinal cross-section. It acts through a force called “compression”. This process can be employed to manufacture solid or hollow profiled bars, with complex geometries and a fixed cross-section, in a single step.
The extrusion process is an optimal solution that in most cases provides financial, environmental and technical benefits to our customer. The waste and cost reductions can be significant when compared with other manufacturing process.
The term Material Handling identifies the discipline that studies the handling and storage of materials (generally including liquids, bulk solids, gases etc.) which is carried out in manufacturing and distribution companies (the term “intralogistics” can also be used), but also in the mining sector, in foundries, ports, etcetera.

The manufacturing of steel pipes through hot extrusion grants an undeniable series of benefits, first of all that of being able to manufacture shaped pipes without any welding. This allows you to avoid the thermal alterations that typically occur at the welding area level.

The three companies of the Calvi Network Hot Extrusion Business Unit are all highly specialized in the use of hot extrusion forming technology to produce special steel profiles or tubes. They work in synergy to produce a wide range of steel and alloy products and they are able to supply both standard profiles and custom solutions of all types and shapes.
