Portal Frame Build Method.All CustomFITT Steel Buildings are constructed using the ‘Portal Frame’ build method,
This means that each building is made up of a series of bays so the more bays you have , the longer it will be.
Each bay consists of two Portal sections, each section is made of two columns and two rafters that are connected by brackets. These frames are then attached to each other using purlins. The only real limitation to the length of building you can have is the size of the plot you are building on!

Cold Rolled Steel All CustomFITT Steel Buildings are constructed using cold rolled steel. Compared to the more traditional ‘hot-rolled’ steel, cold rolled is incredibly strong and durable but much lighter. Combine this with the portal build method and you will have a system that allows relatively small sections to span large distances. The benefits of this?

  • Cuts the cost of materials due to the weight reduction
  • Materials can be packed into tight bundles reducing transport costs (and your carbon footprint!)
  • Cut by manufacturer to exact size and pre punched with fixing holes, eliminating time and expense cutting and drilling on site
  • Reduced construction time which means reduced construction costs
