Sleeved Purlin System

The sleeved system is able to optimise the use of steel through incorporating sleeves at the penultimate rafter with a staggered sleeving arrangement on internal bays. The sleeved system can cater for spans of up to 15m depending on the load to be applied and where the cladding or liner tray provides adequate lateral support through virtue of its screw fixings at 600mm maximum spacings to the purlins.
