Multirib Metal Roofing
Description

Multirib is a medium height, long run roofing and cladding profile designed primarily for industrial and commercial applications. Multirib is also suited for roofing applications on low pitch residential projects.

Key Features
  • Convex ribs provide strength and water run-off away from the fixings
  • Twin capillary breaks on the lap
  • Purpose designed leg provides support to the underlap
  • Steeply angled ribs provide superior strength and aesthetics
  • Installers feet fit neatly in the pan thereby avoiding damage to the ribs
  • Can be “reverse run” and the swage removed for use as a wall cladding
  • Lap can be altered in the reverse run process to ensure improved aesthetics and water tightness
  • Narrow barge flashing detail over wider pan profiles thereby reducing wind uplift damage
  • Fully tested and proven Multirib fastening patterns provide superior wind loading over other commercial priofiles
  • Excellent water carrying capacity 
  • Equally impressive for both roofing and cladding applications
  • Superior spanning at a 3 degree low roof pitch
  • Supported by wind and concentrated load span design graphs derived from extensive industry test rig trials
