Mini rail solar mounting with ONENESS MRS-30 provides a compact, low-profile solution for portrait PV installation on corrugated and trapezoidal metal sheet roofs.
Mini rail solar mounting with ONENESS MRS-30 provides a compact and efficient solution for portrait PV installation on corrugated and trapezoidal metal roofs. The compact aluminum rail is fixed directly to the roof sheet, reducing component quantities and installation time while providing reliable module support. ONENESS MRS-30 Mini Rail is in 385 mm length and 30mm height. It is made of anodized aluminum Al6005-T5 and secured with SUS410 1500h hex flange head self-tapping screws, ensuring strength and excellent corrosion resistance. Designed for corrugated and trapezoidal metal sheet roofs, the system supports PORTRAIT module layouts. Quick and simple installation process, it complies with international wind and snow load standards and offers a service life of over 25 years.
Mini Rail: AL 6005-T5, anodized (15 μm layer) – 1pc
Hex Flange Head Self-Tapping Screws: 5.5 × 30 mm or 5.5 × 40 mm, SUS410, 1500 h salt spray resistance – 4pcs
Rubber pad 2mm
Portrait
Up to 1303mm x 2384mm (width x length)
It must be ensured that the roof structure and building structure have sufficient structural load-bearing capacity and that the roof structure has sufficient compressive load-bearing capacity.

The ONENESS OPVS-MRS-30 mini rail solar mounting system is engineered for fast, low-profile portrait PV installation on corrugated and trapezoidal metal roofs. Designed for efficient installation with fewer components compared with conventional long-rail systems.
With a 30 mm profile height, MRS-30 provides a compact, low-profile mounting solution for applications where minimum system height and efficient material use are preferred.
Faster Installation: Compact rails and self-tapping screws enable quick mounting and reduce labor time.
Lower Project Costs: Reduced material use provides savings without compromising mounting security.
Durable Construction: Anodized aluminum and corrosion-resistant SUS410 screws provide long-term reliability.
Metal Roof Compatibility: Designed for corrugated and trapezoidal roofs with portrait module layouts.
Combining strength, installation speed and material efficiency, the MRS-30 solar mounting system is a practical solution for commercial and industrial metal-roof PV projects.
