Without rail, UR Flat Hook is the most economic solution.

Grace Solar roof hooks are suitable for tin roofs and are with great flexibility. The hooks and the tin roof are clamped and installed without drilling. According to project needs, you can choose between the rail type and the non-rail type, and the installation is as convenient. It is applied to common framed solar panels or frameless solar panels, they are installed in parallel on the inclined roof, and they are suitable for the design and planning of commercial or civil rooftop solar systems.

The Grace Solar Adjustable Tilt Mounting System is suitable for fixing various common framed solar panels at a certain angle relative to the roof. The system can be a fixed angle or an adjustable angle such as 10-15 degrees, 15-30 degrees or 30 ~60 degrees. The unique aluminum alloy extruded rail, oblique mounting clamps, various clamps and a variety of roof hooks can be highly pre-installed and make the installation simple and quick, saving your labor cost and installation time. The customized length can eliminate the need for on-site welding and cutting, thereby ensuring the high corrosion resistance, structural strength and aesthetics of the product from the factory to the installation point.

Grace Solar roof mounting system (hook) is suitable for color steel tile roof, magnetic tile roof, asphalt tile roof and so on.It can be fixed with the roof beam or iron sheet, choose the appropriate span to resist the corresponding load conditions, and has great flexibility. It is applied to the common framed solar panels or frameless solar panels parallel installed on the inclined roof, and is suitable for the design and planning of commercial or civil roof solar system.

The railless design not only saves material, but is also very easy to install. It requires only four parts to complete the installation. Its stability is tested by a certified company to ensure it is safe. At the same time, it is also convenient to earthing.Through the connection of Grace Solar-MC-150, not only the solar panel can be more stable, but also the oxide film on the frame surface of the solar panel can be pierced to achieve the purpose of grounding, and the double-edged effect can be achieved.

The GS Ballast Bracket is an excellent engineering solution to secure the array of solar panels on flat roofs without damaging the roof. The BM4 ballast system is suitable for flat roofs with a certain angle installation required. Besides the system adopts front and rear support feet structure, which is more convenient to install and effectively reduces material and installation costs.
