Structural Steel Beams - FAQs
Below are the most common questions sent to our team about structural steel beams.
-
How much is a steel beam?
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.
Contact Steelo today for a tailored, no-obligation quote for your project. -
How heavy is a steel beam?
The weight of a steel beam depends on several key factors, including its dimensions, type, and material composition. For example, a standard Universal Beam can range from 20kg to over 300kg per metre.
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. -
What size steel beams for loft conversion?
The size of steel beams required for a loft conversion depends on several factors, including the type of conversion, such as Mansard, dormer, or hip-to-gable.
Each type of loft conversion has unique structural demands, with Mansard conversions often requiring larger beams due to their more extensive roof modifications. Span length and load requirements also play a role, as longer spans or heavier loads will necessitate bigger, stronger beams.
Additional considerations include the overall structural design and building regulations. For accurate beam sizing, it’s recommended to contact a structural engineer who can provide tailored specifications for your project. -
Do steel beams need to be painted?
Yes, painting 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. -
Do steel beams need to be fireproofed?
Yes, steel beams often need to be fireproofed to comply with building regulations and ensure safety. Fireproofing helps maintain the structural integrity of the beams during a fire by preventing them from reaching critical temperatures that could cause failure.
Common fireproofing methods include applying fire-resistant coatings, installing protective boards, or using intumescent paint. Contact our specialist team at Steelo to determine the appropriate fireproofing solution for your project. -
How are steel beams measured?
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. -
How far can a steel beam span without support?
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. -
How much are steel beams for houses?
The cost of steel beams for residential construction depends on the beam size, type, and number required. Contact us for detailed pricing tailored to your house project. -
What is the difference between RSJ and Universal Beams?
RSJ (Rolled Steel Joist) is a traditional term used for a type of beam, but today, Universal Beams are more common. Universal Beams offer better load distribution and are tailored for modern structural needs.
