They are described by giving both leg lengths (longer first) and the wall thickness (all in mm), eg. 150 x 100 x 8 RSA. With the longer leg being in a vertical position, its loading capabilities are greater than equal angles, therefore they are often used as lintels.
Unequal angles are also used as brackets for cleat connections. Similar to equal angles, they are often used for balconies, platforms, stairs, concrete supports, etc.

FAQ
Universal Columns are primarily used as vertical load-bearing members in structural steel construction. They provide excellent strength and stability for steel frames, commercial buildings, warehouses and residential developments.
Universal Columns are designed mainly for vertical load applications and feature a more balanced width-to-depth ratio. Universal Beams are typically used for horizontal load-bearing applications such as floor and roof structures.
Yes. Liontek can supply Universal Columns cut to your required length, helping reduce on-site preparation and installation time.
Yes. We offer cutting, drilling, connection plates, base plates and bespoke fabrication services depending on project requirements.
Yes. We provide reliable nationwide delivery for both individual steel sections and bulk project orders.
