Constructed from 100mm flat section galvanised steel laths with acoustic infill and nylon endlocks fitted to alternate laths to prevent lateral movement. The bottom rail comprises a steel capping channel fitted with an integral rubber seal.
The side guides are formed from galvanised steel with twin brush strips and prepared for fixing to the opening structure by means of continuous fixing angles.
The roller is manufactured from mild steel tube of sufficient diameter and wall thickness to resist deflection and is mounted in bearings or cups on each end plate.
Fabricated from mild steel of adequate thickness relative to door size and supplied with angles for fixing to the structure.
Our barrels are normally made from a seamless steel tube of adequate diameter to counteract deflection and hold in bearings or cups attached to the endplates.
