Product Advantages
Superior Corrosion Resistance: Crafted from high-strength Aluminum 6005-T5 and SUS 304 stainless steel fasteners. Integrated waterproof EPDM rubber gaskets provide galvanic isolation, preventing metal-on-metal corrosion and ensuring a watertight seal on all types of metal roofing profiles.
Exceptional Load Bearing: Engineered for structural integrity, these L feet withstand extreme weather conditions, including wind speeds of 130+ mph and heavy snow loads. Mechanical tensile testing confirms a robust load capacity well above standard requirements, ensuring panel security in seismic and high-wind zones.
Universal Compatibility: Designed for a wide variety of metal roof sheets (trapezoidal, corrugated, standing seam). The versatile base plate accommodates common rail hole spacings (40mm, 50mm, or custom), making it compatible with all leading solar rail systems.
Rapid & Cost-Effective Installation: Features a pre-drilled, tool-friendly design with pre-marked drilling templates that simplify alignment with roof purlins. This intuitive design can reduce on-site installation labor time by up to 25% compared to fabricated custom brackets.
Weatherproof Durability: The robust construction, including anodized aluminum and stainless steel hardware, resists UV rays, extreme temperatures (-40°C to 120°C), and salt spray (tested per ASTM B117), making it ideal for coastal, desert, and high-humidity environments.
Code Compliant & Certified: Fully compliant with stringent industry standards, including UL 2703, IEC 62446, and IBC requirements, providing assurance for residential, commercial, and utility-scale projects that demand code-approved mounting solutions.

To provide you with an accurate and engineered solution for your metal roof project, please share the following information:
Panel Dimensions: Length, width, and thickness of the solar panels?
Tilt Angle: What is the desired tilt angle for the panels?
Panel Layout: How many panels in a column and a row? Total number of panels?
Max Wind Speed: What is the maximum wind speed at the project site?
Max Snow Load: What is the maximum snow load at the project site?
Metal Roof Sheet Specification: Please provide the profile type and thickness of the metal roofing sheet.
Company Profile
in one-stop service
Strict ISO 9001 Quality Control: Our entire production process adheres to ISO 9001 standards. We maintain rigorous inspection milestones from incoming raw material inspection (Aluminum 6005-T5, SUS 304) to finished product shipment. Each batch must pass dimensional re-inspection and salt spray corrosion resistance tests before being approved for storage.
ERP-Integrated Intelligent Warehousing: We manage our inventory with a semi-automated warehousing center run by an ERP system. All finished L Feet are pre-packaged by model and batch. This system, combined with barcode traceability and zoned shipping, ensures high efficiency, accuracy, and an average daily shipment capacity that meets large-scale project demands.
