Success story in Haute-Loire :

Since 1920, the VIAL company has mastered the pendulum forging technique and is constantly improving the heating, the precision of the tools and the quality of the products. Initially a manufacturer of rivets, the company turned to the production of mild steel bolts for frameworks and pylons. Then, the company turned to the production of all special screws, head shape, dimensions close to or far from standards, steels on request or specific specifications.

A specific internal organization that allows the delivery of small quantities (approximately 1 to 50 pieces) or medium series (50 to 2,000 pieces) of “quasi-standard” screws treated or galvanized within short lead times. The production of tools in-house ensures VIAL Frères total control of tolerances and production times for sample or pre-production parts.

VIAL Frères has 2,000 hot forging tools for bolts and special screws, allowing it to produce more than 3,500 combinations, which represents more than 700 assemblies per year.

A revolution at the time with a fleet of machines and French know-how, which allowed the production of custom-made forging products for its customers. Among the different ranges offered, a flagship product has stood out, it is called “the double pigtail”. It was sold to EDF and is still produced by VIAL Frères for this customer.
