Wire Rope, Strand & Bunches

Wires can be stranded from annealed or hard material, in a variety of constructions, with pre and post forming to ensure the strand is tight and runs straight without twist.

A particular speciality is the production of resistance strand to meet customers’ specific requirements of resistance or size. Strands of 7, 19, 37 and 49 construction are produced as standard in a wide range of alloys. For applications that require annealed strands, the finished strand can be annealed using the strand annealing lines. Many strands are available from stock, and other strand configurations are available to order.

Our bunching equipment enables us to bunch a range of soft materials, most commonly copper and aluminium, but other materials are available. Our fine machines produce bunches of up to 120 ends of 0.007 wire, while our largest buncher produces up to 30 ends of 0.80mm wire.
