Data entrata in vigore : 20 agosto Data ritiro : 26 aprile Sommario : This part of this European Standard specifies the technical delivery requirements for cold formed welded structural hollow sections of circular, square or rectangular form and applies to structural hollow sections formed cold without subsequent heat treatment.
The specified requirements apply to non-alloy quality steel, fine grain non-alloy quality steel and fine grain alloy special steels as defined in EN The grades, chemical composition and mechanical properties for the non-alloy quality steels are given in annex A.
The grades, chemical composition and mechanical properties for the fine grain non-alloy quality and alloy special steels are given in annex B. The products specified in this part of this European Standard are intended for use in construction. NOTE1: A range of steel grades is specified in this European Standard and the user should select the grade appropriate to the intended use and service conditions. The grades and mechanical properties of the finished hollow sections are compatible with those in EN and EN and some of those in EN Requirements for tolerances, dimensions and sectional properties are contained in Part 2 of this European Standard EN This European standard does not apply to products covered by the following European Standards: EN Hot-rolled products of non-alloy structural steels: Technical delivery conditions EN Hot-rolled products in weldable fine grain structural steels EN Hot-rolled flat products made of high yield strength steels for cold forming EN Structural steels with improved atmospheric corrosion resistance: Technical delivery conditions.
EN Hot finished structural hollow sections of non-alloy and fine grain structural steels EN Weldable structural steels for fixed offshore structures.
