Unlimited Thermal Movement and Watertight Performance

The dynamic nature of a metal roof is embraced and facilitated by the Series 300 system. The unique one-piece concealed clip, made of heavy 16-gauge galvanized or stainless steel, is designed to provide maximum structural integrity while allowing unlimited thermal movement. The clip also elevates the panel 3/8-inch off the substrate to allow for air movement.

The one-piece clip, isolated seam sealant, custom trim, flashing, and system details all work together to accommodate the natural expansion and contraction of metal that occurs when it is exposed to varying temperatures. Each Series 300 roof is engineered for unlimited thermal movement to maintain the roof's structural integrity and provide a lifetime of watertight protection.

Specialty Manufacturing Options
  • Curving (convex, concave and "S" curves)
  • Tapering (to more than 80-feet in length)
  • Long panel factory manufacturing (up to 85 feet)
  • On-site fabrication of factory-quality straight or curved panels is available

The Installer's Advantage
  • Sleek, balanced, proportional look that complements any design
  • No interlocking male/female seams to worry about gives installers better control over when and where panels are installed
    • Install panels in either direction, or both directions, at any time
    • Start from any point on the roof
    • Run simultaneous crews to cut completion time in half
    • Work around roof protrusions and other obstacles
  • Mechanical seamer quickly and permanently seals the seam caps at a rate of 60 feet per minute, and runs in both directions
  • Reduces waste since each piece of a cut panel can be used for the opposite sides of a detail condition
  • If a panel needs to be removed or replaced, ONLY that panel needs to be removed or replaced - not every other panel between it and the roof's edge

  • 20-year finish warranty for Kynar 500® fluorocarbon coatings
  • Materials and workmanship warranty
  • Watertight warranty for qualified applications
