NZ Wood's I-Built rafters are lightweight and fast to install, and are supplied up to 12m long.
A feature of the I-Built range, LD SolidStart I-Beams can achieve long spans by their ability to span over continuous supports which decrease deflection and increase performance.
Available in 225, 240, 300 and 356mm depths, I-Beams can achieve clear unsupported spans of up to 8m, making them the perfect choice 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 NZ Wood Products team can design and provide a full easy-to-follow layout and takeoff to ensure all rafter members, tie-down fixings or hangers are detailed and supplied to site through local timber merchants.
