Merchant Steel bars such as angles, squares, rounds and flat bar are an essential component in the manufacture of various goods. Steel bars of various kinds are widely used in the construction industry. Merchant steel bars provide design flexibility for buildings and structures and have to a certain degree revolutionised the manner in which architects and engineers are able to design structures.

Steel is used in the construction industry because of its exceptional strength and because of its ability to be formed onto numerous custom shapes that differ from the standard steel grades and sizes. There are a number of merchant steel components that are made to conform with certain universal sizes and standards, however some steel bars can be custom made for specialised components. Thinner steel bars are also known as rods and these are typically used in the construction industry to reinforce concrete and are also known as rebars.

One of the most sought after merchant bars used in the construction industry include flat bar. Flat bars are essentially steel plates that are smaller in size when compares to larger steel plates. Flat bars can be used in the manufacture of towers such as telecommunication or electrical towers. Cranes and other construction equipment are also made from flat bars. Flat bars are also further machined into various components and can be cut to size for smaller application such as metal walkways, grills and fencing.

Flat bars are also used in the construction of stairways along with other merchant steel components such as pipes or circular, square or rectangular hollow tubes. These steel components are also known as HSS or hollow structural sections. Merchant bars are also further machined to make joists and purlins which are generally made by machining flat bars. Circular merchant bars are also used to make large bolts used in the mining industry. Merchant bars such as I beams or channels are also used to create metal frames or structures in the construction industry.
