Weld-free & Anti-corrosion, Higher Safety
| Yuanguangbao's New Generation BIPV Photovoltaic Bracket | Traditional Welded Photovoltaic Brackets |
Weld-free & Rust-free, Long Service Life
Modular assembly requires no electric welding. It will not damage the galvanized layer and effectively avoids fire and electric leakage hazards. Made of Zn-Al-Mg alloy, the magnesium element enables self-healing of cut surfaces. It delivers superior corrosion resistance compared with conventional galvanized steel.
Horizontal Layout for Higher Structural Safety
With horizontal layout, modules are mounted with their long sides on purlins. Additional fixing points can be added according to local wind and snow loads to greatly improve wind resistance. It prevents module deformation and cracking, cuts maintenance costs and ensures long-term benefits of PV power stations.
Flange Nuts for Anti-loosening
Flange nuts effectively prevent bolt loosening, bringing worry-free 25-year operation & maintenance for safer use and stable revenue.
Prone to Rust, Short Service Life
Electric welding generates sparks, posing fire and electric leakage risks. Welding damages the galvanized layer. Anti-rust paint can only be applied to outer pipe surfaces instead of inner walls. Corrosion penetrates the pipe from inside within 1~2 years, greatly shortening service life and bringing severe safety risks. Hot work is prohibited in certain hazardous sites, and hot work permits are required in some cities.
Vertical Layout with Poor Safety
In vertical layout, modules rest on purlins by their short sides while the long sides hang suspended. Modules will sag and deform over time, causing microcracks and reducing power generation efficiency. Only four fixing points are used. As modules grow larger with thinner frames, they are vulnerable to tearing and blowing off under typhoons.
Risk of Incomplete & False Welds
Weld quality varies due to inconsistent workmanship of workers. For both commercial and residential projects, 2.0mm thick square tubes are widely adopted. Welding weakens steel strength and makes it brittle. The welds may crack under strong typhoons, resulting in property loss and safety hazards.
Installation Speed Doubled

Modular Assembly, Faster Installation
Simple structure, easy for ordinary workers. No painting or sealing. Can work in light rain. Stable quality, fast acceptance & delivery.
Prefabricated, Minimal Site Work
Factory prefabricated parts. No gutter fabrication. Direct installation cuts construction time by half.
Unstable Welding, Slow Progress
Requires professional welders. Weld quality hard to control; defective welds create safety risks. Construction stops in rain.
On-site Cutting, Low Adaptability
Heavy on-site steel cutting leads to poor matching. Welding & sealing are complex, time-consuming with inconsistent quality.
Integrated Structural Waterproofing
| Yuanguangbao's New Generation BIPV Photovoltaic Bracket | Traditional Welded Photovoltaic Brackets |
Integrated Structural Waterproofing
Strong Adaptability
Works for slopes 5°–15°. Z-shaped gutter delivers superior drainage on steep slopes.
Two-stage Water Diversion
Integrated waterproof design. Short flow path with few layers for fast drainage in heavy rain.
Separated Structure & Waterproofing, Multi-layer Diversion
Poor Adaptability
Only suitable for slopes below 5°. Easy ponding on gentle slopes and overflow on steep slopes.
Four-stage Water Diversion
Long water path. Slow drainage and clogging under heavy rain, leading to leakage.
