topgal standing seam canopy

A standing seam is a type of connection between two multiwall polycarbonate panels. The edges of adjacent polycarbonate standing seam roof panels are turned up and then interlocked with easy-to-fit connectors, ensuring the standing seam roof will be watertight and strong. Standing seam roofing systems minimize air or water leakage, reducing the need for gaskets or sealants.

TOPGAL Polycarbonate Roofing System Includes:

  • Topgal Polycarbonate Standing Seam Panels
  • PC or AI Connectors
  • Connector End Caps
  • PC or AI Side Profiles
  • AI Edge Profiles
  • Fasteners (Panels & Wood or Metal Structures)
  • Anti-Dust Tape

The construction of the Topgal standing seam panel system provides high-quality diffused daylight, increases impact protection, offers solar heat control, and eliminates thermal expansion issues. More natural light can be brought into a building without added structural complexity or loss of insulation.When designed and installed correctly, Topgal polycarbonate coverings are highly resistant to the forces of nature and weather.

This multiwall polycarbonate system is available for purchase by custom quote only.
