ISO 10799-1

Description / Abstract: This part of ISO 10799 specifies the technical delivery requirements for cold-formed welded structural hollow sections of circular, square or rectangular form. It is applicable to structural hollow sections formed cold without subsequent heat treatment.

The grades, chemical composition and mechanical properties for non-alloy steels and fine grain steels are given in Annexes A and B, respectively.

NOTE 1 For the requirements for tolerances, dimensions and sectional properties, see ISO 10799-2.

NOTE 2 For hot finished structural hollow sections, see ISO 12633-1.
