Here’s a list of standard RSJ (Rolled Steel Joist) beam sizes commonly available in the UK, showing just the depth (height) and width dimensions in millimetres — excluding gauge or thickness:

Common RSJ Beam Sizes (Depth × Width in mm):

• 127 × 76 mm
• 152 × 89 mm
• 178 × 102 mm
• 203 × 102 mm
• 203 × 133 mm
• 254 × 102 mm
• 254 × 146 mm

These dimensions refer to the depth (vertical height) and width (horizontal flange) of the beam. These are standard Universal Beam (UB) sizes, often used as RSJs in domestic and commercial construction. When placing two RSJ beams side by side, the combined width increases, but the depth remains the same. We've also listed the most common size of beam combinations using either a 50mm or 100 cavity

Notes for Cladding Design:

• These combinations are ideal for creating wider oak beam cladding while maintaining a manageable depth.
• You can design cladding to wrap both beams as a single unit, giving the appearance of a larger solid oak beam.
• For widths over 300 mm, ensure your oak face is structurally stable and aesthetically balanced.
