BS EN 845-3:2003+A1:2008 Specification for ancillary components for masonry. Bed joint reinforcement of steel meshwork

BS EN 845-3 specifies the requirements for masonry bed joint reinforcement for structural use and for non-structural use.

Where products are intended for use in cavity wall construction, BS EN 845-3 covers only the performance of the meshwork as reinforcement in bed joints and not its performance as wall ties across the cavity.

BS EN 845-3 does not apply to:

a) Products in the form of individual bars or rods

b) Products formed from materials other than specified grades of austenitic stainless steel or zinc pre-coated steel sheet or zinc coated steel wire with or without organic coating.
