Multi Seam (Screwless roof panel)

Advantages
Multi-Seam™ Roof System is steel membrane like structure covering entire building with panels joined together with a double lock standing seam and a uniquely designed clip formed into the seam at the building site in a unique manner that requires no thorough fasteners or holes.

The panels are joined and sealed together by a portable electric seamer.

This roof system is attached to the building with a unique clip arrangement that requires no through panel fasteners yet is securely attached to prevent wind blow off while allowing the roof sheet to move up to 60 mm with thermal expansion and contraction without sacrificing structural integrity.

Single Length Sheet up to 100 mts
The Multi-Seam™ sheets are custom rolled to any transportable length maximum upto 13 meters. However, our specialized service of On-Site Roll Forming enables single length sheet up to 100mts long, without end laps - therefore on most jobs you can have single sheet from ridge to eaves resulting into zero laps, which are otherwise potential areas of leakage. Multicolor™ recommends avoiding end laps for total maintenance free roof.
However if unavoidable two pieces clamped connection is recommended to Seal end laps.
