Square Bar, Round Bar, or Flat Bar?

The knowledgeable team at United Steel is on-hand to help you find the perfect merchant bar product for your project.

A square bar is a solid section featuring a square shape. Mild steel square bars have a variety of frequent uses, including balustrading applications, architectural uses, windows, and door frames. They are a versatile product for commercial buildings, on account of their ease of cutting, welding, and forming.

Similar to its square counterpart, the round bar is a solid section with a circular profile. There are a variety of applications for this style of Merchant Bar within construction and machinery. Round bars are ideal for forming, bending, and machining.

With a flat surface and rectangular shape, flat bars have an extensive list of uses in fabrication. This is thanks to the ease at which they can be cut, drilled, and welded.

Whichever style of merchant bar required for your project, United Steel supplies products that conform to AS/ NZS 3679.1.
