Steel Portal Frame Buildings

Pre-fabricated steel portal frame buildings are superb for use in a number of different applications. Warehouse storage buildings, commercial accommodation, and much more can all be created using steel portal frame buildings – and are especially vital for those on limited budgets with a requirement for such a building.

They are ideal for agriculture, offering a great amount of undercover space, and are also used as aircraft hangars and low rise industrial buildings.

Definitions:

Steel Portal frames can be defined as two dimensional rigid frames which have the basic characteristics of a rigid joint between column and beam. The main objective of this form of design is to reduce bending movement in the beam which allows the frame to act as one structural unit.

The buildings are designed and built in such a way that they are suitable to use for wide span buildings and are therefore an effective means of achieving a low cost warehouse facility.

Applications:

The portal frame building provides effective accommodation for commercial, leisure, agricultural and industrial use and can be used for warehousing facilities, aircraft hangers, milking sheds, sports halls, car parks, factory units and hay barns.

They can be constructed as single or multi-storey construction, with mezzanine floors. Open plan or with sectional internal areas.

Advantages:

Quick - Erection of the building is completed quickly and the building can be available in weeks due to the simplicity of the design.

Economical – Low initial costs with a long life building sited on simple foundations.

Extend or Reduce - Extension or reduction can be done by simply adding or removing modules.
