Product Description
RF01 Universal Standing Seam Solar Clamp | Heavy-Duty Non-Penetrating Roof Attachment
The RF01 Universal Standing Seam Solar Clamp serves as the cornerstone of the Ziyuan Solar metal roof attachment line. Engineered to address the fragmentation in the metal roofing market, this clamp offers a versatile ‘one-size-fits-most’ solution for the most common vertical standing seam profiles found in commercial and residential projects.
Constructed from high-tensile Aluminum Alloy 6005-T5, the RF01 is designed to withstand extreme wind uplift forces up to 60 m/s (134 mph). Unlike inferior cast aluminum clamps, the extruded 6005-T5 body provides superior yield strength, ensuring the clamp maintains its grip during thermal cycling—expansion and contraction of the roof sheet—without loosening over time.
The core innovation of the RF01 lies in its Zero-Penetration Technology. It utilizes two stainless steel (SUS 304) setscrews with blunt, round-point tips. When tightened, these screws compress the seam material against the opposing wall of the clamp, creating a robust mechanical interlock. Crucially, the round-point design ‘dimples’ the metal rather than piercing it, preserving the roof’s protective Galvalume® or paint coating and ensuring the roof manufacturer’s warranty remains intact.
Product Structure
Key Features
- Universal Geometry: The open-throat design accommodates a wide variety of seam widths and heights, reducing SKU complexity for distributors and installers.
- Double-Lock Security: Features two setscrews for redundant holding power. Even in high-vibration environments, the dual-point fixation ensures the clamp remains immovable.
- Corrosion Resistance: The body is anodized (silver treatment) to prevent oxidation, while the stainless steel hardware prevents galvanic corrosion, making it suitable for coastal environments.
- Installation Speed: Pre-assembled screws allow for ‘drop-in’ installation. Installers simply place the clamp and torque the screws, reducing rooftop time by up to 30%.
- Versatile Mounting: The top face includes an M8/M10 slot compatible with L-feet (for rail systems) or direct-attach inter-clamps (for rail-less systems).

FAQ
Q01: What types of roofs is the RF01 compatible with?
A01: It is designed for vertical standing seam roofs, including double-lock, single-lock, and snap-lock profiles. It is not suitable for corrugated or trapezoidal sheet roofs.
Q02: Does the RF01 clamp pierce the roof?
A02: No. It uses non-penetrating round-point setscrews that grip the seam via friction and compression. This ensures the roof remains waterproof and warranties are preserved.
Q03: What is the recommended torque for the setscrews?
A03: We typically recommend 16-20 Nm. However, this varies by roof gauge (thickness). Always perform a pull-test on a sample seam before full installation.
Q04: Can I use this clamp on copper roofs?
A04: No. Aluminum and copper are galvanically incompatible. Use our brass clamp series for copper roofs to prevent corrosion.
Q05: Is the RF01 compatible with IronRidge or Unirac rails?
A05: Yes, the top mounting hole is compatible with standard L-feet used by major racking manufacturers like IronRidge and Unirac.
Q06: Does the clamp damage the roof paint?
A06: The round-point setscrews are engineered to dimple the metal without cutting the paint surface, minimizing any potential for rust.
Q07: What is the wind load rating?
A07: The RF01 is tested to withstand wind speeds up to 60 m/s, making it suitable for most hurricane and cyclone zones.
Q08: Do I need to clean the roof before installation?
A08: Yes, ensure the seam is free of dirt, debris, and oil to ensure maximum friction grip.
Q09: Can I use this for rail-less mounting?
A09: Yes, the RF01 can serve as the base for rail-less inter-clamps and end-clamps.
Q10: What is the material grade?
A10: We use Aluminum 6005-T5, which offers higher tensile strength than the standard 6063 alloy used by many competitors.
Q11: How many clamps do I need per panel?
A11: This depends on your local wind/snow load calculations. Typically, 4 clamps per panel are used in standard installations.
Q12: Are the setscrews included?
A12: Yes, the clamp comes pre-assembled with two stainless steel setscrews and one top bolt.
Q13: Can I reuse the clamp if I move the system?
A13: The clamp body can be reused, but we recommend replacing the setscrews to ensure fresh thread engagement.
Q14: Is it manufactured in an ISO-certified facility?
A14: Yes, our facility is ISO9001 certified, and products meet international standards for grounding and bonding.
Q15: Does it work on horizontal seams?
A15: RF01 is optimized for vertical seams. For horizontal single-fold seams, please use our specialized RF06 model.
