Going green with regards to building materials may take on new meanings depending on where you are building. However, a definition that is fairly universal for a green building states that a green building is erected using methods that increase efficiency within the building and that focuses on conservation of the materials used in both the construction of and maintenance of the building. There are a wide variety of products from which to choose with regard to both increasing efficiency and conserving resources.
These range from using products that improve the efficiency of the insulation and are made from renewable or recycled products. This may include cotton insulation or building using straw or packed earth, therefore increasing the insulation factors. There are some foam products that increase the efficiency markedly that are preformed and use less concrete than traditional concrete block structures. These are becoming more and more accepted in both hot and cold climates, including salt water environments. They are practically indestructible once the construction is finished. Along with the prefabricated building material, metal is becoming a product that is used instead of wood. One of the reasons for this is that metal can be recycled thus adding it to the renewable category of building materials.
In most cases it doesn't matter how often the metal is used, it can still be recycled. Unlike wood which has little or no reusability other than as firewood, most metals can be melted and reused. Once the metal has been recycled, a rollforming process can be used to fabricate products used in the building process. Everything from roofs to beams can be made from steel and used in the construction of both residential and commercial buildings. With the use of hydraulic shears and roll form dies the recycled metal can be punched, cut and reformed into a variety of strong building materials that are as much or more versatile than wood.
As metal forming machinery becomes more sophisticated, so do building materials. Metal is an amazing creative tool in the hands of architects and builders. Without the added cost of creativity, the use of steel offers advantages in framing and cladding roofs and walls. Steel allows houses to be easy and cost effective to insulate. They also are fast and easy to erect, savings money in the cost of construction. Steel also adds the advantage of being capable of withstanding earthquakes better than some of the other construction materials.
With the use of recycled metal along with the rollforming process which includes hydraulic shears and roll form dies puts metals into a green category of viable alternatives to seriously consider when constructing a residential or commercial building.
