Where is steel used in building constructions?
If its a RC frame building (Reinforced concrete) then the steel would be in the form of steel bars ranging in diameter from 8mm to 50mm or mesh depending on the calculations made by architects. These bars would be tied together with mild or stainless steel tying wire to form cages which would then be covered with concrete which form walls, columns and floors. Steel is also used in the foundations of buildings. This can be from small beams in houses or in the form of concrete piles which are basicly long holes drilled deep into the ground and filled with a steel cage and concrete. Other than this the steel could be in the form of RSJs rolled steel joists or steel girders. This is used to build a frame from which floor slabs are suspended.
