DIN EN 1090-5:2017-07

This European Standard specifies requirements for the execution; that is the manufacture and the installation of cold-formed structural aluminium components made from profiled sheeting for roof, ceiling, floor and wall applications under predominately static loading conditions or seismic loading conditions and their documentation. It does cover products of structural class I and II according to EN 1999-1-4 used in structures. Structural elements are understood here to mean profiled sheeting, such as trapezoidal, sinusoidal, liner trays or cassette profiles (Figure 1), that are produced by cold forming. Perforated and micro profiled sheeting are also covered by this part. Welded sections are excluded from this part and are covered by EN 1090-3 except seal welding in low-stress areas. This standard also covers spacer constructions between the outer and inner or upper and lower skins as well as supporting members for roofs, walls and ceilings made from cold-formed profiled sheeting and the connections and attachments of the aforementioned elements as long as they are involved in load transfer, it also covers connections and attachments of these elements. A combination of steel and aluminium structural elements is permitted, such as liner trays made of steel, stiffened by profiles made of aluminium. In this case, EN 1090-4 and this document apply. Composite structural elements where the interaction between dissimilar materials are an integral part of the structural behaviour such as sandwich panels and composite floors are not covered by this standard. This document (EN 1090-4:2017) has been prepared at European Committee CEN/TC 135 "Execution of steel structures and aluminum structures" with German participation. At DIN, the German Institute for Standardization e. V., Working committee NA 005-08-07 AA "Aluminiumkonstruktionen (SpA zu CEN/TC 250/SC 9 and CEN/TC 135)" ("Aluminium structures (national mirror committee for CEN/TC 250/SC 9 and CEN/TC 135)") at DIN Standards Committee Building and Civil Engineering (NABau) is responsible.
