Steel Framed Shed 20m Wide x 6m Eaves Height




As Shown


Structural Drawings on A4 size sheets of a steel framed shed (Universal Beams (UB)), with maximum width of 20m (as measured between outer faces of girts), and maximum eaves height of 6m (as measured at envelope defined by outer surface of wall girts and roof purlins.)

The gable frames are at 5.5m centres, which would suit doors upto 5m wide. The end wall mullions are at approximately 4.9m centres which would suit doors upto 4.4m wide. No doors are shown on the drawings.

With additional details (not provided) the same frame can be adapted for 40m double span shed.

The drawings are provided in pdf file only. The pdf file can be edited to modify the project/installation titles.

Provide a standard design to guide building designers in setting out a building to match a suitable structure. If no significant changes are required then the documents are suitable for submission for development approval, otherwise additional custom drawings maybe required. Alternatively the information in the documents may be transferred to project specific drawings for example to match the sheet sizes of the building design drawings.

A suitably qualified person still needs to be appointed to check the proposal and make sure that the building proposal is compatible with the structural design presented in these structural drawings.

Extras Available Separately

Extras to be released soon:

  1. Evidence-of-Suitability: Calculations as required for development approval
  2. CAD files (dxf, and dwg (AutoCAD LT / ProgeCAD))

  1. A4 drawing sheets adopted, as experience working for big consultancies is that their A1, A0 and B1 drawings are not immediately revised and issued during construction, rather the building is constructed to A4 sketches sent by fax, and the larger drawings revised and issued much later. Therefore may as well produce A4 drawings in the first place. Large drawings also cumbersome in the wind, and add little extra information when working with stick diagrams and details. Steel details typically drawn at scale 1:10, and concrete details at 1:20 no matter what the sheet size.
  2. A4 sheets can be scaled up to A2 and A0 size. Whilst A3 can only be scaled to A1. Unlike the big consultancies which typically start with A1 and reduce to A3, we start with A4 or A3 and expand to A2, A1, A0 only if needed.
