The roof panel is made to order as per design requirements and will free span 4.0m fixed to wall plate and ridge on chamfered timber beams. Longer lengths of panels up to 10.0m max will require support purlins every 4.0m. Any steel supports required will need to be capped with a chamfered timber to suit as per our technical guide. For roofs requiring longer length than 10.0m, these can be manufactured in 2 parts and can be joined at the intermediate purlin.
