Every steel structure is bespoke, as every building is unique. The things that make every project different are the number of storeys to be supported, the spans, any existing layout that needs to be considered as well as the new layout you are looking to achieve. Despite these differences, some structures have similar designs and functions, and this fact has allowed us to use our extensive experience and knowledge to develop a full set of templates for each structure shown below.

Box frame with cross beam
This structure is often used in rear extensions where the cross beam replaces a side wall of the existing building.

Box frame with perpendicular box frame
When loads are high, a bottom beam is required to spread the load onto the foundations.

Box frame with extended beam
When a wall is removed and the new layout does not allow for a column against a wall, for example in a corridor, then one of the columns can be moved towards the centre with this configuration.

2 beams with cross beam
This structure is an acceptable alternative for the ‘Gallow brackets’ that are used to support a chimney breast. The parallel beams span the room on both sides of the chimney, and the cross beam supports the chimney itself. Quite often a top plate is added to this beam in order to spread the support across the entire area of the chimney.

Apex
An ‘apex’ is a double cranked beam, which is supported from a main beam. This structure is used when adding an additional floor to an existing building.

Goalpost
A ‘goalpost’ comprises two columns and a top beam, creating a goal shaped structure. This configuration of beams is used when there are no load bearing walls to support the ends of the beam. It can also be used if there is no party wall agreement in place.

Goalpost with 2 cross beams
This type of structure is used when two perpendicular walls need to be supported, or if the floor span is too high and needs intermediate supports.

Two goalposts with cross beam
Just like the ‘two box frames with cross beam’ structure, this configuration is used when two parallel walls are removed and a perpendicular wall needs supporting. Sometimes the cross beam can be used to support a chimney breast.
