Equal Angles - Angle Irons - Structural Steel Angles

BS EN 10025-2 : 2004 - S275JR / S355JR / S355JO

A staple of the UK construction industry, Steel Equal Angles—often called Angle Iron, RSA (Rolled Steel Angle), or L-Sections—are engineered for symmetry and strength. Featuring two legs of identical length, these sections provide consistent load distribution and exceptional rigidity. Whether used for reinforcement or primary framing, they are a versatile solution for both short-term and long-term loading conditions. We stock a large range of Equal Angles available for immediate off-the-shelf delivery using our own reliable and efficient nationwide transport fleet. 

PRACTICAL APPLICATIONS


Equal angles are the industry standard for roof trusses, tower construction, and strengthening building frames.
They are also used heavily for industrial shelving, machinery stands, and agricultural equipment due to its weldability. In Secondary Steelwork they are a  reliable fix for lintels, floor joists, and architectural frames where a consistent 90-degree profile is necessary.

General Facts
The identical leg lengths ensure consistent load distribution, which is critical for symmetrical support in frameworks and trusses.
We stock a wide variety of grades, including S275JR, S355JR, and S355JO.
Yes; they are widely used for reinforcing existing structural members and as secondary supports like lintels.
Equal angle sizes are listed as Leg Width x Leg Width x Thickness. For example, a "50 x 50 x 5mm" angle means both legs are 50mm long, and the steel is 5mm thick. Since it is an "Equal" angle, the leg measurements will always match.
