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. The Multi-Seam® roofing system is industry’s finest standing seam metal
roofing system with years of weathertight performance and is comparable to
MR-24® roofing system by Butler Manufacturing.
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 panels are permanently seamed together with a full 3600 double lock seam to keep moisture out and designed as water and dust barrier. The raised seam assists drainage.
The seaming process uses a heavy duty, Electric, portable roll forming machine called the Roof Seamer.
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.
