The iron we use today is much better than the iron that the Hittites made: today most of our iron is made into steel. Steel is iron with more carbon in it than regular iron. It is much stronger and more flexible (it doesn't break as easily). People first began making a kind of steel in India, around 250 BC.
As the time passed since the first use of steel, its uses are getting more and more wider. It is now used as sheeting and structural forms because of its amenability to welding and tooling, in automobile and airplane parts on account of its hardness, strength, and elasticity - and in any types of buildings, especially metal buildings. One good idea that was made about steel is by using it as the main material in making carports.
SteelMaster spent its early years developing designs and specifications that would satisfy the agricultural and residential markets such as hay and animal shelters as well as small shops and garages. Now, SteelMaster is one of the best companies who develops one-of-a-kind specifications and designs especially in steel buildings.
