Steel is the most widely used metal in construction products today. While it has been used for many years in commercial and industrial construction, steel has also become very popular in today’s residential building market. Just before the turn of the century, American builders began using lightweight steel products for residential housing much more than ever before.
Today, many builders in Bangladesh are choosing to use steel and steel framing construction in their residential and industrial projects. Part of this increased use is attributed to higher lumber costs and an industry-wide commitment to conserving natural resources, such as timber products.
However, in searching for a more cost-effective solution, many builders have uncovered many other benefits to using lightweight steel products, including beams, joists and studs. We will discuss some areas, benefits and potential issues to consider when contemplating the use of steel products in your next building project.
One of the most obvious advantages to using steel over wood in residential construction is durability. While steel is much stronger than wood products, there are other durability advantages as well. Wood is susceptible to termites and other pests, while steel does not. Steel also provides a home with extra strength in the case of earthquakes, fires and other natural disasters.
Architects, designers and builders are finding many advantages to using steel over wood in residential and industrial construction in Bangladesh. One of the most beneficial opportunities is the ability to span greater distances with steel ceiling joists versus wooden ones. This allows architects to expand their options, allowing them to create new space using steel products that just weren’t available with other materials.
However, a home that has been built with steel can actually be less energy efficient than a building built out of wood. Metal transfers hot and cold temperatures 400 times faster than wood. Additional insulation can be used to stop this transfer of heat, specifically wrapping steel framing with rigid insulation in addition to use of conventional insulation between studs. Once the issue of insulation and energy efficiency is understood, however, this no longer remains a problem for steel construction.
Steel is one of the most recyclable products in the world. Many dealers purchase used steel as scrap. In the year 2000, over 70 million tons of steel were recycled, including steel framing construction products, cans, cars, appliances, bridges and much more. Currently, steel has an overall recycling rate of over 64 percent in the United States alone. Using recycled steel saves energy and natural resources, which in turn, lowers the cost for producing new steel products.
The Benefits of Using steel can be used in a number of ways. A basic oxygen furnace method is used to create flat-rolled steel products, such as steel framing, automobiles, appliances and cans. An electric arc furnace is used to make new steel products, such as structural beams, rebar, steel plate and other products that require long shapes. Both furnace methods can take recycled steel products and make them into new products to be used in residential and industrial construction in all over the world.
This way we can save enough energy to power hundreds of thousands of homes for a year with electricity. Just reusing a ton of steel, which is the amount usually found in a scrapped car, can save as much as 120 pounds of limestone, 1400 pounds of coal and 2500 pounds of iron ore. Every bit of steel that you recycle help to save energy and natural resources. This is the most important issue in the field of construction at present.
