As the popularity of pre-engineered buildings and structures is rising, the demand for high quality auxiliary and support structures is also increasing. A good example of this is the variety of strong, sturdy metal roofing sheets and cladding solutions that are now available in the market. Metal roofing is now extensively used due to its relatively low cost in comparison to the durability it affords. Many types of metal can be used to manufacture such roofing. Corrugated galvanized iron, copper, flat-seam or standing-seam metal, or steel coated roofing that uses an alloy of zinc and aluminum, are just some of the variants. Corrugated galvanized iron, i.e galvanized steel roofing, which is widely used in commercial and industrial applications like industrial sheds, warehouses and hangars, is favored because its wavy corrugation provides great resistance to damage through flexing. This type of roofing has been use for many decades now, but is now being replaced with coated steel, which makes use of the many advantageous properties of zinc and aluminum. It is lighter in weight than the former, but has all its benefits as well as strength. Copper is also extremely easy to fabricate, and needs very little maintenance, besides offering the option of being recycled.
