Longze Universal Solar Mounting Hardware provides a high-performance structural interface engineered specifically for photovoltaic modules and racking systems. Utilizing high-tensile AL 6005-T5 Aluminum and Marine-Grade Stainless Steel 304, our comprehensive hardware kits—including Mid Clamps, End Clamps, L-Feet, and Hanger Bolts—are designed to ensure a secure, vibration-proof, and corrosion-resistant assembly capable of withstanding 25+ years of rigorous outdoor service.
Our precision-engineered components are CNC-machined to fit standard module frames ranging from 30mm to 50mm, eliminating localized stress on the solar glass. By integrating DIN 6923 serrated flange nuts, our systems significantly reduce field installation labor while guaranteeing critical electrical continuity and structural safety, making them ideal for residential rooftops, utility-scale solar farms, and BIPV systems.

Frequently Asked Questions
To prevent galvanic corrosion. Using zinc-plated carbon steel with aluminum creates a galvanic cell that destroys the hardware; SUS304 ensures electrochemical compatibility.
We typically recommend using a torque wrench set to 12-15 N.m to ensure the module is secure without over-stressing the frame.
Yes, we manufacture specialized EPDM-lined clamps specifically designed to secure frameless glass modules without causing micro-cracks.
The serrated flange "bites" into the anodized aluminum surface, locking the assembly against the thermal expansion and contraction typical in outdoor environments.
Absolutely. We offer Black Anodized hardware that maintains the 12μm+ protection layer while providing a premium matte finish for aesthetic integration.
We provide specialized grounding pins or washers that pierce the anodized layer, ensuring a safe electrical bond for lightning protection.
