Steel arch buildings discussion
To build a 2,000 square foot dwelling from wood you would need to harvest 40 to 50 trees, whereas buildings of the same size in steel would only require six recycled cars! Physical health and safety also get high marks with steel. First of all, steel is not conducive to molds and mildews, unlike wood buildings. Since steel is galvanized, it does not rust. 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.
