What is BS EN 1090‑4 about?
BS EN 1090 is a series of European standards on steel and aluminium structures that discusses the technical requirements of the structures. BS EN 1090‑4 is the fourth part of a series of documents on steel structures and aluminium structures. BS EN 1090‑4 specifies requirements for the execution, i.e. the manufacture and the installation, of cold-formed structural steel members and sheeting and cold-formed structures for the roof, ceiling, floor, wall and cladding applications.
BS EN 1090‑4 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. BS EN 1090‑4 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. BS EN 1090‑4 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 aforementioned elements as long as all are involved in load transfer.
BS EN 1090‑4 covers steel profiled sheeting for composite floors, e.g. during installation and in the stage of pouring concrete. Composite structural members 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.
NOTE 1: BS EN 1090‑4 does not cover the necessary analyses and detailing and execution rules for thermal insulation, moisture protection, noise control and fire protection.
NOTE 2: BS EN 1090‑4 does not cover regulations of roof cladding and wall cladding, produced by traditional plumber methods or tinsmith methods.
Who is BS EN 1090‑4 for?
BS EN 1090‑4 on steel structures and aluminium structures is relevant to:
- Structural engineers
- Civil engineer
- Welders
Why should you use BS EN 1090‑4?
A steel structure is a metal structure that is made of structural steel. Structural steel is very stiff in respect to its cross-sectional area and thus can support a high load without excessive sagging.
BS EN 1090‑4 provides you with the best guidance on requirements that should be taken into account for the execution of structural steelwork for roof, ceiling, floor, wall and cladding applications. This includes structures and manufactured components produced from hot rolled, structural steels; cold-formed components and sheeting; hot-finished and cold-formed structural hollow sections, welding, mechanical fastening, erection, inspection, testing and correction.
As a user of BS EN 1090‑4, you can ensure adequate levels of mechanical resistance and stability, serviceability and durability of structures of the roof, ceiling, floor, wall and cladding applications. BS EN 1090‑4 assist you in manufacturing and installing structural steel. BS EN 1090‑4 is helpful for the welders working on structural steelwork. Inspection, testing and correction methods provided by BS EN 1090‑4 helps the user in maintaining the quality of the product. BS EN 1090‑4 helps you in prolonging the service life of roof, ceiling, floor, wall and cladding structures
