The use of steel as a primary agent for building construction began in the 18th Century with the use of iron columns being installed within the walls of buildings. This use of iron beams and columns expanded during the end of the century, becoming a commonplace feature in large, industrial buildings. Steel has been since instrumental in the construction of bridges, pipelines and modern day skyscrapers. This phenomenal growth of steel has exploded during the past few years, fueled in part by our growing environmental concerns. Our need to preserver our forests and save our planet has added to the steel structure allure. The fire has spread and steel buildings are now catching world-wide interest. The fact that steel is economical, environmentally friendly and offers additional security and protection moreso than its wooden counterparts also adds to its developing popularity. Steel is quickly replacing wood as the building material of choice in the construction world.
