These are specialized, non-penetrating mounting components designed to securely attach solar panel rail systems to the standing seams or corrugations of “metal sheet roofing” (often colloquially called "tin roofs," though typically steel or aluminum).

Key Features:
1.  Material: Fabricated from “high-strength aluminum alloy”, often anodized for enhanced corrosion resistance and durability in harsh outdoor environments.
2.  Function: They act as clamps, gripping the raised profile (standing seam or rib) of the metal roof panel securely without requiring any holes to be drilled through the roof surface. This preserves the roof's waterproof integrity.
3.  Design
    *   Typically consist of two main parts: a lower base that sits on the roof deck and an upper clamping jaw.
    *   The solar mounting rail is fastened directly onto the top of the clamp, usually via a T-slot or bolt hole.
    *   The clamp mechanism (lower base and upper jaw) is tightened together using stainless steel bolts, applying strong, even pressure to grip the roof profile firmly.
    *   Often incorporate an EPDM rubber or neoprene pad between the clamp and the roof metal.
4.  Compatibility: Specifically shaped to match the profile (height, width, shape) of common standing seam profiles or corrugated/trapezoidal rib  patterns found on metal roofs.
5.  Advantages of Aluminum:
    *   Lightweight: Minimizes additional load on the roof structure.
    *   Corrosion Resistant: Highly resistant to rust and atmospheric corrosion, especially when anodized. This is crucial for long-term performance.

Art Sign has many designs for solar clamp. These aluminum clamps provide a strong, corrosion-resistant, and non-penetrating method to anchor solar mounting rails directly to the structural ribs or seams of metal sheet roofing. Their design ensures a watertight seal and protects the roof surface while offering a reliable foundation for the solar array.
We also have many solar panels accessories, like solar mounting rails, roof hooks, ect
