The uses for portal roofs are endless - from magnificent swimming pool enclosures to large commercial extensions; anything is possible due to the flexibility and advanced engineering of the large span system

A portal frame is an aluminium box section 'skeleton' used to support a roof. It sits on the inside of the cill line and the windows and doors form a cladding to the outside of the portal.

The aluminium is usually powder coated to complement the windows, doors & surrounding buildings. A portal frame is required when the roof may exceed the sizes set out in the design guide or when the design of the roof cannot be supported by the window frames.
