Eight Fast Facts about Steel

  1. Steel is a “green” building material, mostly because it is highly recyclable.  According to the American Iron and Steel Institute, more than 80 million tons of steel are recycled each year in North America …
  2. … which saves enough energy to power approximately 18 million homes across North America every single year!
  3. While we are on the topic of green building, did you know that steel can actually be more environmentally friendly than wood? It’s true! It takes almost 40 trees to make a 2000 sq. ft. house, whereas a house of the same size can be constructed using steel from only four recycled cars. Furthermore, a steel house can easily be recycled into something else.  Wood is usually only good for one build.
  4. It takes A LOT of steel to engineer a building.  Did you know that it took 83000 tons of steel to build the Golden Gate Bridge?
  5. Steel is one of the most widely-used (and most heavily recycled) materials on the planet.
  6. According to the Canadian Steel Producers Association, the construction of Canadian steel takes on two forms: 1) the Integrated (BOF) process, which relies on high quality iron ore, coal and limestone to produce molten iron in a blast furnace, which combines molten iron and scrap steel to create a liquid Basic Oxygen Furnace (BOF) which is then cast into slabs, and 2) the Electric Arc Furnace (EAF) process, which primarily uses reheated recycled scrap steel which has been purified and recast as new steel from an electric arc furnace.
  7. Steel is one of the strongest and most durable resilient materials out there.  In addition to its ability to withstand harsh weather conditions, steel is fire and weather resistant.
  8. Steel is easy to work with.  Pieces can come pre molded and are easy to assemble, meaning that a steel building is normally put together faster than that of a building constructed using other materials, lessening production costs.
