EN 508-2 is a CEN standard for self-supporting aluminium profiled sheets used for roof covering, wall cladding, lining and liner tray products in discontinuous laying. It sets requirements for the product characteristics, materials, classifications, labelling and test methods that manufacturers use to design and declare the product, and that purchasers use to check conformity before the product is released.

What does EN 508-2 specify?

EN 508-2 specifies requirements for self-supporting external profiled sheets made from aluminium sheet, with or without surface treatment such as organic coatings or anodising. It is written for products that are intended to perform in normal service conditions and to keep wind, rain and snow out of the building while transferring loads to the structure.

The scope covers general characteristics, definitions, classifications and labelling, together with the material requirements for the aluminium and surface finishes used to make the products. It excludes products used for structural purposes in the sense described in the document, and it does not cover the supporting construction, roof or cladding design, or the execution of connections and flashings.

The document is organised into scope, normative references, terms and definitions, requirements, test methods, and marking, labelling and packaging. It also includes two annexes that support measurement and testing.

Annex	What it covers
Annex A	Normative dimensional tolerances and measurement methods for trapezoidal sheets, sinusoidal profiles and tiles
Annex B	Informative test methods and references for concentrated load

What are the key requirements of EN 508-2?

EN 508-2 focuses on material selection, declared mechanical performance, dimensional control and fire-related classification. In practice, the standard tells the manufacturer what to choose, what to declare and what to measure so the sheet can be specified and checked consistently.

Materials and supplied product quality

Clause 4.2 requires the product to be made from materials that comply with the relevant material requirements. For aluminium, the standard limits the suitable alloys to those listed in Table 2, and their properties must meet the relevant material standards. The temper must be chosen so that the ultimate tensile strength is not lower than 150 MPa.

This matters because the alloy, temper and coating finish control strength, formability and corrosion resistance. The supplier is also responsible for the tests needed to confirm conformity and should provide inspection documents on request.

Surface finish and coating systems

Clause 4.2.2 covers factory-applied organic coatings such as acrylic, polyester, silicone-modified polyester, PVDF, PUR, PUR-PA, SP-PA, AK and EP, as well as factory-applied laminated film. Clause 4.2.3 allows anodised surfaces and points to EN ISO 7599 for anodised product specifications.

The practical point is that coating choice is not only aesthetic - it must fit the substrate, pre-treatment, top coat and climate conditions. The document also notes that reverse-side coating may be used for handling, storage or corrosion protection, so buyers should agree the coating build-up at ordering stage.

Mechanical resistance and design data

Clause 4.3.1 requires the manufacturer to state the cross-sectional, material and member characteristics needed for design and use-related verification at the place of use. The product has to resist the relevant design loads from self-weight, insulation if applicable, membranes, snow, wind and maintenance for roofs, and from self-weight, insulation and wind for cladding.

Clause 4.3.2 requires the mechanical performance to be declared together with the values used to determine it. For calculation and testing, either national regulations or EN 1999-1-4 may be used.

For users, this means the sheet is not just a shape and thickness choice - the declared performance has to match the actual roof or wall design conditions. The document also makes clear that trapezoidal sheets are the main focus of the calculation and test methods, while tiles, standing seam sheets and concealed fix sheets are normally designed by testing within proprietary systems.

Dimensions and thickness classes

Clause 4.3.3 requires dimensions to be fixed so the assembled roof or cladding can do its job. Thickness measurements are taken not less than 40 mm from the edges, in line with EN ISO 9445-1 and EN ISO 9445-2, and the product is classified into thickness classes 1, 2 or 3.

This is important because thickness affects strength, stiffness and the way the product is treated in design calculations. For class 3, the mechanical resistance is calculated using the minimum thickness of the aluminium core stated by the manufacturer.

Dimensional tolerances

Clause 4.3.4 sends profile-shape tolerances and the related measurement methods to Annex A. Annex A gives tolerances for key geometry such as depth, pitch, crown and valley widths, cover width, bend radius, straightness, squareness, length and side lap.

For a buyer or inspector, this is the section that supports acceptance checks on delivered sheets. The measurements are factory checks before delivery and are corrected to 20 °C where appropriate.

Safety in case of fire

Clause 4.3.5 states that aluminium is non-combustible and will melt in a severe fire, so the whole structure still has to be assessed. For reaction to fire, the document uses the euroclass system. Non-organically coated products are considered to satisfy Class A1 without testing, and certain polyester-coated products are also treated as Class A1 under the stated limits.

This matters because fire performance is often set by building regulations rather than by the sheet alone. The document also notes that external fire roof performance, when required, is defined using the euroclass system.

Marking, labelling and packaging

Clause 6 requires each pack, bundle or delivery unit to identify the manufacturer, the product designation, the order or batch number, dimensions and quantity, and gross mass. It also asks the parties to agree packaging and special conditions at ordering stage, and it gives handling guidance for transport and storage.

That information supports traceability, site control and damage prevention. In practice, it helps keep products identifiable and helps avoid deformation, moisture staining and handling damage.

What terms does EN 508-2 define?

• self-supporting product - a product that carries applied loads by virtue of its own material and shape and transfers them to spaced structural supports.
• temper - the material condition after production steps such as mechanical treatment and/or heat treatment that give the aluminium its required properties.
• organic coated aluminium sheet - aluminium painted, post-coated, laminated or coil coated on one or both sides.
• anodized aluminium sheet - aluminium with an anodic coating produced by electrolytic oxidation to form a mainly oxide surface.
• trapezoidal profiled sheet - a self-supporting sheet designed for side and end lapping, with crowns that may be rounded and may be stiffened.
• standing seam and concealed fix sheet - a self-supporting sheet with hidden fixings that are not exposed to the weather.
• tile profile - a part of a typical tile profiled sheet that can allow side and/or end lapping.
• PVDF - polyvinylidenefluoride paint coating, one of the named organic coating designations used in the document.

Who uses EN 508-2?

EN 508-2 is used by aluminium product manufacturers, roof and cladding system suppliers, purchasers, specifiers, and testing or inspection personnel. Manufacturers use it to choose suitable alloys, coatings and tolerances and to declare mechanical performance.

Purchasers and buyers use it to check that the delivered product matches the agreed designation, thickness class and labelling before it is put on the market or dispatched from the factory. Designers and technical teams use it when they need product data for roof or wall application, while labs and inspectors use it for dimensional checks, load-related testing and conformity review.

What changed in EN 508-2 from the previous edition?

EN 508-2 supersedes EN 508-2:2019. The significant technical change stated in the document is that the list of aluminium alloys suitable for roofing and cladding products has been extended, and the change is located in 4.2.1.

Which standards are used with EN 508-2?

• EN 485-1 - provides the aluminium sheet, strip and plate inspection and delivery terms used for the material definitions.
• EN 485-4 - provides shape and dimension tolerances for cold-rolled aluminium products.
• EN 1396 - provides the performance and test methods for coil coated aluminium, including surface properties.
• EN 14782 - supports product specification and requirements for self-supporting metal sheet, and is used here for reaction-to-fire specimen information and concentrated-load reference.
• EN ISO 7599 - gives the specification method for anodised aluminium coatings.
• EN 1999-1-4 - is the design reference named for aluminium structural sheeting when mechanical resistance is calculated or verified.
• EN 508-1 and EN 508-3 - are the companion parts of the EN 508 series for steel and stainless steel products.

What does the EN 508-2 document contain?

EN 508-2 includes a framework introduction, a full set of terms and definitions, and a requirements section covering materials, mechanical resistance, dimensions and fire-related performance. It also contains tables of suitable aluminium alloys and factory-applied coatings, plus figures that define common profile shapes such as trapezoidal, sinusoidal, standing seam, concealed fix and tile profiles.

Annex A is a detailed measurement annex. It gives the tolerances and methods for checking profile geometry, straightness, squareness, length, side laps and curved sheets, which is what fabricators and inspectors use for acceptance testing and factory control.

Annex B gives references for concentrated-load testing where European test methods are not available. The document also includes a designation example and a marking, labelling, packaging and storage section, so users can identify the product and handle it correctly from delivery through installation.
