This British Standard specifies requirements for sheets of factory-made machine-welded fabric for the reinforcement of concrete, manufactured from ribbed bars conforming to this British Standard or BS 4449:2005+A3:2016, or manufactured from bar/wire conforming to BS 4482 for wrapping fabrics D49 and D98.

This British Standard does not set out fatigue requirements. Fabric manufactured from bars conforming to the fatigue requirements of BS 4449:2005+A3:2016 and weld requirements of this standard may be considered as a welded bar for fatigue assessment purposes. F500A bars may only be used for predominantly static loading.
