19x7 wire rope is recommended for hoisting unguided loads with a single-part line. The rotation-resistant properties of this rope are superior to those of the 8x19 class wire ropes, and are secured by two layers of strands. The inner strands are left lay, while the 12 outer strands are right lay, which enables one layer to counteract the other layer’s rotation.
Galvanized wire rope (steel) features a compressed zinc coating for providing excellent corrosion resistance. With a higher break strength, yet lower price than stainless steel wire rope, galvanized steel wire rope is widely used in general engineering applications such as winches and security ropes.
The bright class of industrial wire rope is produced without a surface treatment—making the rope less likely to untwist or kink while giving it a stronger crush resistance than lay ropes. Generally, they are fully lubricated to protect the rope from rust and corrosion. Also available in USA-made.
