The cold rolling is a key technology in our manufacturing process. PSE has been working with cold rolling for more than thirty years. Every year, more than 2.000 tons of round wire are shaped in our rolling mills. In order to meet the needs of our clients, rolling mills and rollers used for rolling operations are developed, maintained and checked directly by our personnel. The internal rolling process makes PSE stand out with respect to many other companies that do not roll internally but purchase profiles from other companies. The internal rolling process allows PSE to meet the needs of clients using only few kilograms of material. The internal rolling offers obvious economic advantages, with a low need for raw materials. The costs of the equipment are limited too, since we can use existing rollers or develop special ones directly in our plant. This allows PSE substantial manufacturing flexibility, allowing small production lots to run while ensuring reduced lead time.
