The Solar Mounting Pressing Fittings supplied by Guojian are suitable for photovoltaic frames ranging from 30mm to 55mm, and are perfectly compatible with the C-type, Z-type, U-type steel, and zinc-aluminum-magnesium guide rails produced by our factory. The surface is treated with anodizing, offering excellent corrosion resistance, and is suitable for various application scenarios such as ground power stations, distributed rooftop systems, and agricultural photovoltaic complementary projects.
1. Integrated OEM solution with specifications perfectly matched to components
2. One-piece extruded 6005-T5 aluminum alloy construction for high structural strength
3. Weather-resistant EPDM cushioning pads to protect module frames
4. Wide clamping range compatible with all types of PV modules
5. Anodized finish for long-lasting corrosion resistance and outdoor durability
6. Includes 304 stainless steel anti-loosening fasteners to prevent rust and seizing
7. Mass-produced on automated lines, ensuring stable supply for large-scale projects
Large-scale megawatt-class PV bases in plains, mountainous areas, or deserts; paired with hot-dip galvanized or Zn-Al-Mg coated C-channel rails; uses mid-clamps and end-clamps for secure array mounting with excellent wind, snow, and load resistance.
Solar Mounting Pressing Fitting is Projected on color steel tile or flat concrete roofs; lightweight aluminum clamps reduce overall roof load; compatible with various array layouts; easy installation without compromising roof waterproofing.
Agrivoltaic, fishery-PV, pastoral-PV, and salt-field PV stations; Zn-Al-Mg rails paired with corrosion-resistant aluminum clamps withstand saline-alkali soil and high-humidity environments (e.g., over fishponds).
Steel-structure PV carports and agricultural PV greenhouses; compatible with adjustable-tilt and tracking mounts; flexible use of long and short clamps to adjust module spacing.
Residential and C&I PV projects in Southeast Asia, Europe, and Africa; English installation manuals available; corrosion resistance specifications suited for rainy or coastal climates; complete mounting system kits available for export.
Torque < 18 N·m: Insufficient clamping force; modules may slip or generate noise during high winds. Torque > 25 N·m: Excessive pressure deforms the module frame, causing micro-cracks in the glass and subsequent power output degradation.
Direct metal-to-metal contact without a pad scratches the anodized frame and causes electrochemical corrosion; long-term rainwater infiltration leads to frame rusting and damage.
Aluminum clamps must not be paired with carbon steel bolts; contact between aluminum and iron in the presence of rainwater causes electrochemical corrosion, leading to seized or broken fasteners in the short term.
Grinding damages the anti-corrosion anodized layer, causing cut edges to rust rapidly; if size adjustments are needed, request custom-made non-standard parts from the factory in advance.
Strictly avoid using narrow-grip clamps on excessively thick frames; this creates a gap between the clamp and the frame, concentrating stress and likely crushing the module.
Installation is not recommended Solar Mounting Pressing Fitting when temperatures are below 0°C; low temperatures harden the EPDM pad, reducing cushioning performance and risking damage to the module frame. Ensure roof tiles and mounting rails are dry before installation following rain.
Conduct routine inspections every six months; re-inspect every three months for coastal or fishery-solar projects. Perform comprehensive checks on bolt tightness and pad aging after typhoons or heavy snowstorms.
Store uninstalled clamps in a dry warehouse inside sealed, moisture-proof cartons; avoid exposure to direct sunlight or rain to prevent premature aging and failure of the rubber pads.
