scope:

This European Standard specifies requirements for the execution i.e. the manufacture and the installation of cold-formed steel structural elements and cold-formed structures for roof, ceiling, floor and wall applications. This European Standard applies to structures designed according to the relevant part of EN 1993. This European Standard applies to structural components and sheeting as defined in EN 1993-1-3. This European Standard may be used for structures designed according to other design rules provided that conditions for execution comply with them and any necessary additional requirements are specified. This European Standard also specifies requirements for the execution i.e. the manufacture and the installation of structures made from cold formed profiled sheeting for roof, ceiling, floor and wall applications under predominately static loading or seismic loading conditions and their documentation. This European Standard covers products of structural classes I and II according to EN 1993-1-3 used in structures. Structural elements are understood here to be: - profiled sheets, such as trapezoidal, sinusoidal, liner trays or cassette profiles (Figure 1), or - members (linear profiled cross sections) that are produced by cold forming (Figure 2). This European Standard also covers: - Not welded or bolted build-up sections of thicknesses not greater than 3 mm. - Cold-formed hollow sections including the welding of the longitudinal seam, not covered by EN 10219-1. - Perforated, punctured and micro profiled sheeting. This European Standard also covers spacer constructions between the outer and inner or upper and lower skins for roofs, walls and ceilings made from cold-formed profiled sheeting and the connections and attachments of the afore mentioned elements as long as all are involved in load transfer. This European Standard covers steel profiled sheeting for composite floors. 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 European Standard does not cover the necessary analyses and detailing and execution rules for thermal insulation, moisture protection, noise control and fire protection. Annex B of this standard concerns provisions which the designer has to take into account and which are not yet included in EN 1993-1-3. The guidelines in this annex may be wholly or partially superseded by future guidelines added to EN 1993. This European Standard does not cover detailed requirements for water tightness or air permeability resistance and thermal aspects of sheeting. - single- or multi-skin roofs, whereby the load-bearing structure (lower skin) as well as the actual roof covering (upper skin) or both consist of thin-gauge structural elements, - single- or multi-skin walls whereby the load-bearing structure (inner skin) as well as the actual cladding (outer skin) or both consist of thin-gauge structural elements, or - trusses from cold formed members.
