Over deze norm
NEN-EN 1090-4 defines the requirements for the manufacture of thin-gauge cold-formed steel elements, the execution of structures made from such elements (e.g. roofs, coverings, walls, floors, ceilings) under predominately static loading conditions and their documentation. It does cover products of structural classes I and II according to EN 1993-1-3 used in structures. Thin-gauge structural elements are understood here to mean profiled sheeting, such as trapezoidal, sinusoidal, liner trays or cassette profiles (Figure 1) or linear profile cross sections, (Figure 2), that are produced by cold forming and have thicknesses not greater than 4 mm. Closed build-up sections of thicknesses not greater than 3 mm, as defined in EN 1993-1-3 are also covered by this part. Perforated and micro profiled sheeting are also covered by this part. For closed build-up sections (Figure 2c) of thicknesses greater than 3 mm the execution provisions of EN 1090-2 apply. Welded sections are excluded from this part and are covered by EN 1090-2. 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 afore mentioned elements as long as they are involved in load transfer. Steel profiled sheeting for composite floors are covered by this standard. 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.
