Our steel beam calculator is created to be easy to use yet it does need some understanding of steel light beams and structures. To make your life easier, we've meticulously explained what information is needed for every area of the Calculator. If you require help with any of this, call us on 020 831 186 42.

Steel Beam Details

Steel Beam Span Length. For the Steel Beam, Span Length tell us the span length of the beam. This is the range from the centre of one end bearing to the centre of the other end bearing. 

As an example: The clear distance between supports is 3m. The beam has a minimum end bearing length of 0.1 m at both ends. So you would work out the span length as adheres to in number below: 3m + 0.1 m/2 + 0.1 m/2 = 3.1 m.

Load Details. You should understand what kind of load your beam will be supporting.Uniformly Distributed Load is where the load is equally distributed across the complete length of the beam.

Partial Uniformly Distributed Load is where the lots are evenly dispersed throughout part of the beam.Point Load is where there are localised loads at specific points along the beam.

Uniformly Distributed Loads and Partial Uniformly Distributed Loads. Select one of these types.  e.g. "Sloping roof covering with an angle of up to 30 levels or timber floor in a domestic dwelling". You can then get in the Width or Height of the load. 

We also have a checklist of Standard long-term loads for generally used items, such as clay floor tiles and rafters.

You can add multiple loads. E.g. much more roofing, floors, wall surfaces etc.  per type or you could add one more tons type. You do not need to add the weight of the steel beam of light itself; our calculator automatically does this.

Security. Security is critically important. Occasionally when getting rid of a load bearing wall, you will have to install a steel type goalpost arrangement. This is where the steel light beam is sustained at both ends by steel posts. This is only called for if there wants masonry for the building to stay steady.

If the geometry of the stonework complies with the advice in Regulations Approved Document A. Steel goal posts will not generally be required. Steel goal posts may not be needed, and you may not be skilled in designing them. We would suggest that you use an experienced Structural Engineer to make these for you.
