Metal roofs and walls made of steel come in a variety of colors, but it's their "green" makeup that is prompting many building owners and architects to sit up and take notice. For building owners and architects committed to preserving natural resources, metal roof and wall panels offer a unique, environmentally responsible and sustainable solution to their building's exterior requirements. That's because roof and wall systems made of light gauge steel can contribute considerably to the green building movement due to their high recycled content, recyclability, sustainability and energy efficiency. The recycled content of the steel used in metal roofs and walls, for example, is at least 25%. This level of recycled content reduces both the cost and environmental impact of making new steel, as it conserves energy and other natural raw materials. The fact that the recycled content of steel is at least 25% also helps earn points in the U.S. Green Building Council's Leadership in Environmental and Energy Design (LEED) program.
