AlliedShield Standing Seam is a 24" wide panel with a standing rib which is machine double lock seamed 2 7/8" above the drainage surface.
The system's two piece sliding clips connect the weathering surface to the structure, eliminating panel to structure fastener penetrations and allowing the weathering surface to move with temperature changes, thereby resisting thermal shock. High energy efficiency is achieved with concealed clip standoff design which minimizes compression of the insulation.
With 6 inches of fiberglass insulation an R-value of 17.29 can be attained. The system's heavy 22-gauge or 24-gauge steel materials with long life coating and Underwriters
Laboratories class 90 rating for wind uplift resistance reduces maintenance costs. Shell white is standard, but all other colors are available as special order. |

DuraRib is a 36" wide panel with 1 1/8" high ribs on 12" centers. It is available in 24-gauge and 26-gauge steel.
The 80,000 pound per square inch yield enhances walkability, resistance to hail damage and load carrying capacity. The purlin bearing leg design makes panel alignment and fastener engagement consistent. Tape sealant at panel laps prevents water migration and air infiltration.
Dura-Rib fasteners are coated with an organic material that tests seven times more resistant to rust than the typical .0003 cadmium-zinc coated fasteners.
The system has both 30 and 90 classification from Underwriters Laboratories, Inc., for wind uplift resistance. Shell white is standard, but all other colors are available as special order. |
