Galvanized steel is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface often called a "spangle".The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel with a series of distinct iron-zinc alloys. The resulting coated steel can be used in much the same way as uncoated. Galvanized steel can be welded; however, one must exercise caution around the resulting zinc fumes. Galvanized steel is suitable for high-temperature applications of up to 392 Degree F 200 Degree C. Use at temperatures above this level will result in peeling of the zinc at the intermetallic layer. Wire rope consists of several strands laid or 'twisted' together like a helix. Each strand is likewise made of metal wires laid together like a helix. Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Multiple wire strands, cables and wire ropes are actually machines. Each component wire and strand physically adjusts to contribute to the cable or wire ropes load bearing capacity. Generally the more wires in a strand, cable or wire rope the more flexible it behaves. A typical Loos and Co. product is 7x19 cable. In this cable there are seven strands of nineteen wires each, (7x19=133). There are 133 wires working together as a machine in this particular construction. Each application has a construction best suited for it. Wire rope is often sold with vinyl and nylon coatings. This increases weather resistance and overall durability.
