BS EN 14353:2007+A1:2010EN 14353:2007+A1:2010 (E) 4 Introduction Metal beads and feature profiles are produced in wide variety of siz
22、es and shapes. They are cold formed from mild steel sheets with various protective coatings or extruded or cold formed from aluminium. Some of the beads are faced with paper tape to enable them to be jointed. The materials, design and mechanical properties make them particularly suitable to provide
23、improved physical properties and/or enhanced decorative solutions to plasterboard assemblies. Metal beads and feature profiles may be fixed by various methods to the plasterboard and may be featured self-finished, featured with decoration or concealed by finishing with jointing compounds to receive
24、decoration. Figures 1 and 2 show the relationship between this standard and the set of standards prepared to support gypsum plasterboards.

27、use in systems made with gypsum plasterboards, gypsum boards with fibrous reinforcement and products from secondary processing complying with the ENs shown in Figure 2, intended to be used in building construction works. Metal beads and feature profiles, depending upon their material and type, can b
28、e featured without decoration, decorated or finished with jointing compounds to receive decoration. It covers the following performance characteristics: reaction to fire and flexural strength (bending behaviour) to be measured according to the corresponding European test methods. It provides for the
29、 evaluation of conformity of the product to this EN. This European Standard covers also additional technical characteristics that are of importance for the use and acceptance of the product by the construction industry and the reference tests for these characteristics. 2 Normative references The fol
