Three common wire strand constructions are:
- 1×19 indicates 19 thin wires twisted together in a silky and therefore smooth finish. Consequently, 19 individual wires twisted together construct a single strand of our premium wire. This is the least flexible wire structure. As a result, it is the easiest to keep clean.
- 7×7 indicates a collection of 49 individual wires grouped as 7 sub-strands of 7 wires each. Consequently, 7 wire bundles twisted together form a single strand. This is more (medium) flexible wire than 1×19. As a result, it is for ‘general purpose’ applications and is most economical because it is commonly available.
- 7×19 indicates a collection of 133 individual wires grouped as 7 sub-strands of 19 wires each. Consequently, 7 wire bundles of 19 wires twisted together form a single strand. This is our most flexible wire for use in rigging or small cranes or winches rather than balustrade construction. Low Cost Wire does not recommend 7×19 wire for balustrade construction.
…In conclusion, the more wires twisted to make a strand, the more flexible is the strand of wire because it deforms/bends without damage.
