BS EN 508-1 is the first part of multiple series that specifies requirements for self-supporting roofing, covering, wall cladding, lining, liner tray and tile products for discontinuous laying made from metallic coated steel sheet with or without additional organic coatings. Sheets intended to be used with insulation and membranes are also covered.
BS EN 508-1 applies to all discontinuously laid self-supporting external profiled sheets for roofing covering, wall cladding, lining, and liner trays, with the exception of tiles with a surface area less than 1 m2 and produced by stamping.
NOTE-
BS EN 508-1 does not cover products for structural purposes, i.e., it does cover products used in constructions of structural Class III (according to EN 1993-1-3), it does not cover products used in constructions of structural Classes I and II (according to EN 1993-1-3) intended to contribute to the global or partial stability of the building structure by providing racking resistance or resistance to permanent static loads (excluding self-weight of the metal sheet).
No requirements for supporting construction, design of the roof, cladding, lining, tile system and execution of connections and flashings are included.
BS EN 508-1 on roofing and cladding products from metal sheet is useful for:
Metal cladding is a form of external wall cladding most commonly crafted from tough galvanised steel. A cladding metal sheet is used as external cladding for wall and roof partitions. It is used in cold storage sites, for constructions and cladding metal sheeting; or for warm storage sites: constructions, thermal insulation material, and cladding box profile sheet.
BS EN 508-1 helps you design the profiled sheets which keep wind, rain and snow out of the building. BS EN 508-1 establishes general characteristics, definitions, classifications and labelling for the products, together with requirements for the materials from which the products can be manufactured. If you are a manufacturer, it helps you to comply with the requirements. If you are a purchaser, it helps you to verify that the products comply with the requirements when purchased, before they are dispatched from the factory. It specifies the requirements for products that enable you to meet all normal service conditions.
BS EN 508-1 defines the performance of the product in terms of calculation and a number of type tests. With the help of BS EN 508-1 you can ensure the performance of a roof or of the cladding in relation to the environment and conditions.
BS EN 508-1:2021 supersedes BS EN 508‑1:2014, which is withdrawn.
In comparison with EN 508-1:2014 the following technical changes have been made:
