In the world of sophisticated steel design, standard symmetry is not always the answer. The Unequal Angle, defined by its distinct L-shaped profile with one leg longer than the other, is the perfect solution for projects with specific spatial constraints. This unique geometry allows architects and engineers to place strength exactly where it is needed without adding unnecessary bulk to a structure.
At Hangan Steel, we specialize in providing these precision-rolled sections for those tricky junctions where a standard angle simply won’t fit. Whether you are supporting a complex masonry facade or building custom mechanical brackets, our unequal angles offer a tailored approach to structural integrity.

Hangan Steel is the premier choice for unequal angles melbourne builders rely on when standard sections aren’t enough. While Equal Angles are the “all-rounders” of the industry, structural steel angles victoria often requires the specialized profile of a UA. These sections feature a “long leg” and a “short leg,” offering different bending capacities on each axis. This makes them highly effective for applications where horizontal support needs to be wide, but vertical space is limited.
All our stock is manufactured as AS/NZS 3679.1 steel angles, ensuring high-grade 300PLUS structural performance. Whether you are performing a heritage restoration or a modern commercial build, our UA steel sections melbourne provide the certified strength and weldability your engineering plans demand.
Calculating the correct unequal angle properties australia is essential for ensuring your frame can handle specific load-bearing requirements. Below are the most common UA steel sizes victoria available through our fabrication facility.

The unique “long-short” leg profile of unequal angles melbourne makes them the ideal choice for several specific construction challenges in Victoria:
Often used as lintels where the long leg provides a wide "seat" to support a brick skin, while the short leg remains hidden within the wall cavity.
Ideal for mounting machinery where a large bolting surface is required on one side, but the attachment point on the other side is restricted.
The long leg provides a safe and wide surface for the step, while the short leg acts as a slim vertical attachment to the stringer.
Providing a sturdy edge for roof lines or floor slabs where a specific depth is required for aesthetic or drainage purposes.
At Hangan Steel, we go beyond simple supply. Our steel angle fabrication victoria services ensure your UA sections are delivered “install-ready.” Working with unequal legs requires a higher level of attention to detail to ensure the correct orientation on-site.
We can pre-drill bolt holes in either the long or short leg with absolute accuracy, following your structural drawings.
We provide clean, square cuts to your exact specified lengths, reducing waste and on-site labor.
Perfect for creating specialized frames that must wrap around existing structures or fit into tight corners.
We offer hot-dip galvanizing for structural steel angles victoria used in coastal areas or exposed external environments to prevent long-term rust.
Why Choose Hangan Steel for Unequal Angles?
Choosing Hangan Steel means you get the “Builder Advantage.” We understand that UA steel sizes victoria are often specified for the most complex parts of a frame. Our detailing team reviews your plans to ensure the orientation of the long and short legs is perfect before any steel is cut. With our rapid delivery across Melbourne and the Mornington Peninsula, we keep your project moving forward without delay.
In our technical charts and on your engineering plans, the first measurement always refers to the long leg. For example, in a 125 x 75 UA, the 125mm leg is the long one.
Yes, though Equal Angles are more common for simple “X” bracing. Engineers specify unequal angles melbourne for bracing when they need higher stiffness in one specific direction.
Absolutely. We provide galvanized UA steel sections melbourne for any application that will be exposed to the weather, ensuring your structural steel remains protected for the life of the building.
