Roofing and cladding products from metal sheet - Specification for self-supporting products of steel, aluminium or stainless steel sheet - Part 2: Aluminium

This part of EN 508 specifies requirements for self-supporting external profiled sheets for roof covering wall cladding, lining and liner tray products for discontinuous laying made from aluminium sheet with or without surface treatment (additional organic coatings or anodising).
The standard establishes general characteristics, definitions, classifications and labelling for the products, together with requirements for the materials from which the products can be manufactured. It is intended to be used either by manufacturers to ensure that their products comply with the requirements or by purchasers to verify that the products comply before they are made available on the market before being despatched from the factory. It specifies the requirements for products which enable them to meet all normal service conditions.
The standard applies to all discontinuously laid self-supporting external profiled sheets for roof covering, wall cladding, lining and liner trays with the exception of tiles with a surface area less than 1 m2 and produced by stamping. These profiled roof sheets are designed to keep wind, rain and snow out of the building, and to transfer any resultant loads and infrequent maintenance loads to the structure.
This standard does not cover products for structural purposes, i.e. it does not cover products used in structural class III (according to EN 1999 1 4), it does not cover products used in constructions of Structural Classes I and II (according to EN 1999 1 4) intended to contribute to the global or partial stability of the building structure by providing racking resistance or resistance of permanent static loads (excluding self-weight of the metal sheet).
No requirements for supporting construction, design of roof system and execution of connections and flashings are included.

1 Scope

This part of EN 508 specifies requirements for self-supporting external profiled sheets for roof covering,

wall cladding, lining and liner tray products for discontinuous laying made from aluminium sheet with or

without surface treatment (additional organic coatings or anodising).

This document establishes general characteristics, definitions, classifications and labelling for the

products, together with requirements for the materials from which the products can be manufactured. It

is intended to be used either by manufacturers to ensure that their products comply with the

requirements or by purchasers to verify that the products comply before they are made available on the

market before being despatched from the factory. It specifies the requirements for products which enable

them to meet all normal service conditions.

This document applies to all discontinuously laid self-supporting external profiled sheets for roof

covering, wall cladding, lining and liner trays with the exception of tiles with a surface area less than 1 m

and produced by stamping. These profiled roof sheets are designed to keep wind, rain and snow out of

the building, and to transfer any resultant loads and infrequent maintenance loads to the structure.

This document does not cover products for structural purposes, i.e. it does cover products used in

structural class III (according to EN 1999-1-4), it does not cover products used in constructions of

Structural Classes I and II (according to EN 1999-1-4) intended to contribute to the global or partial

stability of the building structure by providing racking resistance or resistance of permanent static loads

(excluding self-weight of the metal sheet).

No requirements for supporting construction, design of roof system and execution of connections and

flashings are included.

NOTE 1 Aluminium sheet is used either without coating or with organic coatings mainly for aesthetic reasons.

It should be noted that different coating systems behave in different ways under various climatic

conditions. The primer and/or adhesive should be chosen taking into account which type of substrate,

pre-treatment and top coat are used.

Reverse side painting or coating is used if being required for handling and storage reasons as well as for

corrosion protection in some installation conditions.

Performance and test methods for coil coated aluminium shall be in accordance with EN 1396.

Special coatings or films may be applied to the reverse side to reduce the dripping of moisture caused by

condensation.
