With natural roof and façade metal materials that have been in use for centuries, importance should be placed on specifying a material not solely for its longevity, but also with an understanding of its long-term aesthetic potential (and pitfalls).
Many different types of concrete construction projects can use reinforcing steel (rebar), including architectural buildings, exposed beams and columns, bridge decks, and various transportation infrastructure projects. The steel embedded within is essential to the performance of these structures.
Zinc is naturally found in elements such as air, water, and soil as well as in plants, animals, and humans. It is the 27th most abundant element in the Earth’s crust and is infinitely recyclable without the loss of its properties, making it a true renewable resource.
Economic reasons make carbon sheet steel popular for metal roofing, but the material can corrode when exposed to both oxygen and moisture. For this reason, steel typically has a coating, but the protective role differs among products.
