Structural Steel

Structural steel welded beams are made from a combination of a web and two flanges, welded together to create a single beam capable of handling demanding loads. At Southern Steel QLD, our welded beams are manufactured in Australia from 300PLUS steel and exceed the minimum requirements of AS/NZS 3679.2.

Welded beams are designed for engineering specifications where standard hot-rolled beams are not suitable.

‘UC’ or ‘H beam’  columns are square-shaped dimensions designed to support weight on a vertical axis. This design makes them ideal for applications where strength must be similar in both directions and the beam needs to be resistant to twisting. Universal columns are a key component of any major support or structural stability in building construction. They are manufactured in Australia from 300PLUS steel and exceed the minimum requirements of AS 367**.

Welded columns are made concurrently along both flange-web joints in a horizontal position. They are a vital component in the construction of commercial and industrial buildings and large-scale engineering projects. Southern Steel QLD supplies the full range of welded steel columns.  Our welded columns are manufactured in Australia from 300PLUS steel and met the requirements of AS/NZS 3679.2.

Steel angles are roll-formed steel formed by bending a single angle in a piece of steel, creating an ‘L’ shaped product. Equal angles have two axes of the same length (equal) that make a 90-degree angle. They are a multi-purpose steel component often used for reinforcement, framing, trims and brackets. They can be cut to any size and made in various strengths and thicknesses. The larger the steel angle, the more weight and stress-bearing properties.  Equal angles are manufactured in accordance with AS/NZS 3679.1.

Unequal angles have two axes of different lengths (unequal) that create a 90-degree angle. The cross section has the same shape as an upper case ‘L’. Unequal angles are used in bridge building, reinforcements, framing and brackets and are made in various thicknesses and strengths. Southern Steel QLD will cut to any size. Our unequal angles conform with AS/NZS 3679.1.

Parallel flange channels (PFCs) are hot-rolled carbon steel channels, sometimes called ‘C sections’ or ‘C channel beams.’ Constructed using a vertical web and top and bottom horizontal flanges with inside radius corners, the shape provides superior structural support, making parallel flange channels an ideal product for frames and braces. They are used for machinery, enclosures, vehicles, truss support beams, floor beams and portal frames. PFCs are available in a wide range of sizes and thicknesses.
