How do you achieve a steel beam appearance without sealing and penetration issues?

The visual impact of an exposed steel beam can be used to define cladding and floor levels on a building’s façade. However, the use of a traditional steel beam could result in penetration or sealing issues around the I-beam. The architectural desire for having exposed beams can result in a number of penetration and finishing problems.
Penetration problems can result in water ingress to the structure and the difficulty in finishing off a steel beam is highlighted by the typical solution of galvanising and then painting.
Galvanising by its nature is rough, leaving a poor finish which can only be painted after the galvanising has been allowed to weather (or with etching which, if incorrectly carried out by inexperienced operatives, will result in the paint delaminating very quickly and causing a continuous maintenance problem). Typically, wet paints are used for this which require redecorating on a regular basis.
It’s possible to deliver the same visual effect as a steel beam using the precision extrusion of lightweight pre-finished aluminium.
The Bailey I-Line product was developed to provide the aesthetic appearance of an exposed beam, that overcomes any penetration problems. Due to the nature of its attachment to the building, no structural penetration is required, and as it is manufactured from aluminium, Bailey I Line can be polyester powder coated to provide a maintenance free solution.
This architectural cladding feature provides a number of benefits:

  • Combines the inherent precision and structural integrity of extrusion with the flexibility of pressed sheet
  • Consistently true leading edge
  • Variable fixing options to suit all applications
  • Defines cladding elements and demarcates floor levels
  • Suitable for vertical applications
  • Suitable for cills, window surrounds and cladding frames

The other aesthetic benefits of the system are that the aluminium can be supplied in a range of colours, and finished either by anodising or using a powder coated finish.
Additional benefits become more apparent on-site. The pre-fabrication of the I-line system prevents alignment issues. The ‘snap-on’ fixing method makes it quick and efficient to install, and the “fins” can be snapped on as the scaffold comes down to reduce the risk of damage by follow on trades.
This type of product can also be used in conjunction with a cassette system to deliver an eaves solution or as part of a external building envelope.
