6 Manufacturing processes
All welded fabric shall be factory made and machine welded. The joints, at the intersection of the longitudinal bars and the transverse bars, shall be made by electrical resistance welding to provide a specified shear resistance.
Welded fabric can be composed of a different steel grade in each direction.
9 Test methods
For welded fabric, the requirements of BS EN SO 15630-2 apply regarding the tensile test, rebend test,the determination of shear force of joints and the methods for chemical analysis. Measurement of the surface geometry and the determination of the relative rib arear shall be in accordance with BS EN ISO 15630-1.
10 Identification of the manufacturer and steel grade The manufacturers identification mark applied to the individual bars shall be as described in BS 4449:2005.
In addition to the manufacturers identification marks applied to the individual bars, a label shall be attached to the welded fabric to indicate the manufacturer of the welded fabric and the steel grade(s).
