This European Standard specifies requirements for execution of structural steelwork as structures or as manufactured components, produced from: a) hot rolled, structural steel products up to and including grade S690; b) cold formed components and sheeting up to and including grades S700 for stainless steels and including S690 for carbon steels; c) hot finished and cold formed austenitic, austenitic-ferritic and ferritic stainless steel products; d) hot finished and cold formed structural hollow sections, including standard range and custommade rolled products and hollow sections manufactured by welding. This European Standard may also be used for structural steel grades up to and including S960, provided that conditions for execution are verified against reliability criteria and any necessary additional requirements are specified. This European Standard specifies requirements independent of the type and shape of the steel structure (e. g. buildings, bridges, plated or latticed components) including structures subjected to fatigue or seismic actions. 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 applies to steel components in composite steel and concrete structures designed according to the relevant part of EN 1994. 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 specifies requirements related to execution classes. This European Standard specifies requirements related to geometrical tolerances. NOTE Geometrical tolerances required by EN 1993 design rules are covered by the essential tolerance type. This European Standard gives requirements for surface cleanliness prior to surface preparation for application of a protective treatment, and special requirements for surface finish of stainless steel structures. It also gives requirements and guidelines relating to the execution of corrosion protection for carbon steels. This European Standard does not cover requirements for watertightness or air permeability resistance of sheeting. 2
