Cool steel arch buildings
The best thing about metal is that it is completely recyclable. More metal is recycled annually than glass, paper, aluminum and plastic combined, which amounts to approximately sixty million tons per year! To give a better picture of the environmental benefits, consider that you are able to build a 2,000 square foot home out of metal from six recycled cars. With wood, you would need to cut down forty to fifty trees to build a dwelling of comparable size with wood! Physical health and safety for humans also rank high with metal buildings. First of all, metal is less likely to mold or attract mildew like organic building materials. Metals that are galvanized will not rust due to galvanization.
