introduction

Hybox® 355

fully complies with the European Standard for cold formed structural hollow sections, EN10219 S355 J2H and is used in a wide range of construction and mechanical related applications including wind bracing and machinery.

Hybox® TT 355-700

A cold formed structural hollow section with Tight Tolerances (TT). It offers customers consistent shape and ready-to-paint surface finish. The ends of the tubes are clean, safe and free of burrs. Available in a high yield strength up to 700 MPa and goes beyond the European Standard EN 10219, offering half the dimensional tolerances to enable trouble-free, automated processing.

With an excellent surface finish, Hybox TT can help improve manufacturing efficiency, output and end product quality. Hybox TT is a great choice for a range of demanding applications – from hard-working agricultural equipment and cranes to construction and mechanical applications.
