Structural Steel Beams

The cost of a steel beam varies based on its size, type, and weight, as well as your specific project requirements. As every project is different, from both commercial to residential builds, prices vary according to the individual project requirements.

A standard Universal Beam can range from 20kg to over 300kg per metre. This can vary depending on the beam’s dimensions, type, and material composition.

Steel density and any additional treatments or coatings can also impact the overall weight. Whether you have a commercial or residential project, our experienced engineers can help calculate the exact weight for your needs.

The size of steel beams required for a loft conversion varies depending on:

• Type of conversion
• Length and load requirements
• Structural demands
• Building regulations

Different types of conversion have unique structural requirements, with Mansard conversions often requiring larger beams due to their more extensive roof modifications. Other types include dormer, or hip-to-gable.
Span length and load requirements also play a role, as longer spans or heavier loads will necessitate bigger, stronger beams.
For accurate beam sizing, it’s recommended to contact a structural engineer who can provide tailored specifications for your project.

Yes, painting structural steel beams is often necessary to protect them from corrosion, especially in environments exposed to moisture or weather. Coatings can also enhance aesthetics when beams are visible in the final structure.

Additionally, painting or applying protective treatments may be required to meet building regulations and prolong the lifespan of the steel.
STEELO provides specialist structural steel finishes for increasing the longevity of steel, including RAW, PRIMED, and GALVANISED finishes.

Yes, steel beams often need to be fireproofed to comply with building regulations and ensure safety. Common fireproofing methods include:

• Type of conversion
• Length and load requirements
• Structural demands
• Building regulations

Fireproofing helps maintain the structural integrity of the beams during a fire by preventing them from reaching critical temperatures that could cause failure. Contact our specialist team at STEELO to determine the appropriate fireproofing solution for your project.

​Steel beams are measured by their depth, flange width, and flange thickness. For instance, a 203x102x23 Universal Beam is 203mm deep, 102mm wide, and weighs 23kg per metre.

The span of a steel beam depends on its size and load capacity. Typically, beams can span between 3 to 12 metres, but a structural assessment is recommended for precise calculations.
