BWG is a reference gauge system. Your millimetre diameter and the applicable tolerance govern the delivered wire. EN 10218-2:2012 can be specified for relevant dimensional tolerances.
Show the wire's natural dark finish and tightly wound coil form.
Confirm the nominal diameter and applicable tolerance with your order.
Wire drawing establishes the requested diameter. Annealing provides the flexibility needed for twisting, tying and coil handling.
Wire diameter and finish are controlled during preparation for annealing.
Heat treatment and cooling set the wire's softness for the requested use.
Specify steel grade and chemistry required for the order.
Draw the wire to the target metric diameter.
Set the annealing and mechanical requirements for the intended tying method.
Confirm coil weight, surface condition and packing presentation.
Choose soft annealed wire for secure hand tying and bundling. Match the wire diameter and finish to your working conditions.
Flexible tie wire for rebar intersections, reinforcement cages and reinforcement placement.
Specify straight cut or loop-tie formats when your handling operation needs prepared ties.
