Wrought iron was actually "wrought" (i.e. worked or hammered) into bars and has been used as a construction material for thousands of years. Most metals used for construction purposes are alloys. For example, steel is an alloy with iron and carbon being the primary elements.

The most common conveyor belts are general-use belts. These solid belts typically feature materials including rubber or a fabric such as nylon, polyester, neoprene, or nitrile. Belt properties determine the conveyor belt's primary applications.

An average commercial steel building costs between $16 and $20 per square foot, including building package (I-Beams, purlins, girts etc.) , delivery, foundation and the cost of construction.

It was not until 1880 that an era of construction based on reliable mild steel began. By that date the quality of steels being produced had become reasonably consistent. The Home Insurance Building, completed in 1885, was the first to use skeleton frame construction, relying on its masonry cladding for stability.

Belt types are: 1) Flat belts. 2) Rope drives. 3) Round belts. 4) Spring belts. 5) V belts. 6) Multi-groove belts. 7) Ribbed belts. There are five main materials that conveyor belts are made out of: thermoplastics, metal, rubber, fabric and leather.
