Easy Installation with Long Spanning I-Built Roofing Systems

When designing roofing systems, I-Built LP SolidStart I-Beams from New Zealand Wood Products (NZWOOD) Ltd are the perfect choice to achieve a strong, lightweight, long spanning rafter system.

Supplied up to 12m long, I-Built Rafters are easy to handle and fast to install. I-Beams can achieve long spans through their ability to span over continuous supports which decreases deflection and increases performance. Available in 225mm, 240mm, 300mm and 356mm depths, I-Built I-Beams can achieve clear unsupported spans of up to 8 metres in some scenarios, making them ideal for long span mono-pitch roofing. The I-Beam profile ensures a structurally efficient use of timber while also allowing for a potentially higher roof R-Value.

The technical team at NZWOOD can design and provide a full easy to follow layout and take-off to ensure all rafter members, tie-down fixings and hangers are detailed and supplied to site through a local timber merchant.

When designing rafters, NZWOOD recommends deflection and span should be restricted to 80% of the suggested maximum, which will ensure the roof and ceiling linings perform as intended.
