Multicolor® Roof System is a 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 through 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
The Multicolor® 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.
Roof clips securely attach the roof panels to the supporting structurals by stainless steel tabs which are roll formed into the panel seam.
Stainless steel tabs are 50% stronger than other galvanized standing seam tabs. The clip design allows for 32 mm of movement in either direction to accommodate expansion and contraction forces. This permits buildings up to 500 feet wide without the need for special expansion joints.
Multi-Seam® has 51mm high ribs providing strength and beauty. The recommended minimum roof pitch for the profile is 2º ( 1 in 30 ). If the purlin and the roof plane are perfectly aligned Multi-Seam® can be used for roof slope as low as 1º Steep Slope, Low Slope, and Flat Roof profiles can all be designed with standing seam metal roof.
