Aluminum Solar Roof Clamp Standing seam roof clamp is for tin/metal roof solar rooftop mounting. The solar roof clamps makes mounting on folded seam roof particularly easy. The clamps are simply attached to the standing seams and offer a secure fastening without penetrating on the roof, ensuring great stability with minimum weight. The variety of system combinations allows it to be connected quickly to all rail components. It can also fix panels directly with solar panel clamps.

Features of metal roof solar mounting racks
1. Versatile roof clamp for different roof types.
2. Easy and fast with unique rail and module/flat nut.
3. Pre-assembled parts to save cost and installation time.
4. Without penetration on the roof structure surface
5. Anti-corrosion
