Rope Suppliers
As there are nearly as many types of rope as there are natural and synthetic fibers, suppliers can provide either a broad range of products or cater to a specific market. Agricultural, shipping, fishing, transport, search and rescue, climbing, construction, logging, masonry, sporting goods, defense contracting and travel industries are just a sample of the many applications for which rope is needed. Private residential projects often require the use of rope as well, further expanding the market possibilities. Rope suppliers generally offer more than the cords themselves. Rope supply stores and companies frequently sell rope accessories as well. Clamps, cams, eyes, hooks, grommets, turnbuckles, links and rings are common metal and plastic components needed in rope related work.
The general process for the production of rope begins the same no matter the fiber. First the natural fibers are harvested or synthetic fibers are chemically and mechanically produced. These materials are then spun into yarn or thread. Varying quantities of these threads are twisted or braided together to form rope. While twisted ropes are not uncommon, braided ropes are gaining popularity due to their added strength. The number of threads is often directly related to firmness and tensile strength, which should be considered carefully in relation to its intended use. The number of strands, commonly referred to as the ply, is also one manner of determining the grade of a given product. Standard plies range from one to eight, though many consumers choose to select ropes based on the diameter of the cord rather than this number. Treatments such as copper napthenate, tar, urethane or tallow may be added to minimize loss of strength due to fungi, mildew and rot in addition to adding protection against chemical corrosion and chaffing in high stress situations. These treatments can significantly prolong the working life of a rope product. While treatment is important, further considerations include strength lifts, abrasion resistance, flexibility, lay and cord size. Rope suppliers can provide insight into the rope requirements for a specific task.
