FAQ

ST37 / ST52 / S355 Structural Steels FAQ

Are ST52 and S355 the same?

ST52 is an older DIN designation commonly associated with S355 families in the current EN system. Impact class and delivery condition must be verified on the certificate.

What is cold-drawn ST37?

A structural-steel grade name does not define the section or surface-finishing process. Specify hot-rolled or cold-drawn condition, section, dimensions and tolerances separately in the order.

Are flat and square sections available?

Round, square, hexagonal and flat sections may be supplied subject to stock and sourcing.
