The most common constructions for fiber rope slings are 3-strand laid, 8-strand plaited, and hollow braided nylon Ropes come in a variety of shapes and sizes. Ropes The primary types of nylon rope construction are diamond braid (which offers the greatest strength, flexibility, and durability), solid braid (flexible, but strong and durable), and twisted (known for both elasticity and strength). 1981. It is clearly impossible to go into detail for every application. 1 Diversity of ropes.
