Steel arch buildings, online exploration
For an eye opening comparison of the environmental benefits, consider that you can build a 2,000 square foot home from the steel of six recycled cars, whereas you would need to cut down forty to fifty trees to do the same job in wood! Steel buildings also score high on the physical health and safety scales. For one, steel is less conducive to mildews and mold than wood buildings. Steel does not rust due to the galvanization process. As a result, you will typically find superior indoor air quality to that of other structures. A big safety concern with a lot of buildings is that of fire hazards.
