Product Overview
The LF-MR Series L-Feet are core connecting components specifically designed for metal roofs (such as standing seam, corrugated, and trapezoidal sheets). They act as the critical bridge between the solar mounting system and the roof, safely and reliably transferring the structural loads from the PV array to the building. Manufactured from high-strength aluminum alloy or stainless steel, these products are precision-engineered and rigorously tested to ensure exceptional performance and long service life in various harsh environments.
 
Key Features & Advantages
 
Excellent Compatibility & Adaptability
Wide Compatibility: Multiple models are available to perfectly match mainstream standing seam metal roofs, corrugated metal sheets, and trapezoidal metal roof panels.
Flexible Adjustment: Some models feature elongated holes or an adjustable range for fine-tuning during installation, ensuring precise positioning of the PV rails.
No-Penetration Mounting, 100% Roof Protection
Core Technology: For standing seam metal roofs, the L-Feet are secured directly to the panel's seam via dedicated clamp components, requiring no drilling into the waterproof roof layer. This fundamentally eliminates leak risks and maximally protects the building's original integrity and waterproofing.
Superior Structural Strength & Durability
Premium Materials: Primarily made from high-strength 6005-T5 aluminum alloy or 304/316 stainless steel, offering an excellent strength-to-weight ratio and outstanding tensile and compressive performance.
Powerful Clamping Force: The proprietary clamp design provides immense holding power to withstand extreme weather like strong winds and heavy snow loads, ensuring system stability.
Exceptional Corrosion Resistance
Surface Treatment: Aluminum alloy components are anodized, and stainless steel components are of mill-grade. Both offer superior corrosion resistance, effectively combating corrosive environments like acid rain and salt spray, guaranteeing a design life exceeding 25 years.
Easy Installation, Saves Labor Time
Modular Design: Features standardized connection interfaces for rails and clamp components, making the installation process simple and intuitive.
Pre-Assembly Design: Some components can be pre-assembled, significantly reducing on-site installation time and labor costs.
