The Advantages and Disadvantages of Steel and Reinforced concrete Construction Steel Construction Steel is a metal alloy composed of iron, carbon, and other elements. It is classed as mild steel, medium carbon steel, high carbon steel, low alloy steel, or high alloy steel based on its chemical composition. The majority of structural steel forms are elongated beams with a distinct cross section.
