What is a portal frame?
A portal frame is a common term used in the shed industry and is the frame that spans from side to side at regular intervals (known as bays) along the length of your shed. The length of the shed is determined by the number of “bays” your shed contains e.g. a 9m shed would consist of either 2 x 4.5m bays, or 3 x 3m bays.
