COMMENTS

The technology developed by Sapes is the cold extrusion of a sole steel bar, whereas all the other European manufacturers are still using the system of joining the end parts by means of welding. The process used by Sapes offers lower production costs and moreover avoids the criticality regarding the integrity of the joined component.
