High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.

In the factory cluster of Hamamatsu City, Shizuoka Prefecture, a solar power generation system supported by Grace Solar's mounting structures is transforming the energy landscape of this industrial city. Technological Innovation Supporting the Transformation of an Industrial City Grace Solar's ground-mounted structures maximize power generation efficiency in limited spaces through precise design and smart manufacturing. With special alloys and anti-corrosion treatment, they can withstand salt damage and typhoons in Shizuoka's coastal areas. The installation accuracy and speed have exceeded the expectations of local partners, establishing a new standard for solar power generation in industrial zones. Industrial Aesthetics of the Installation Site Engineers pre-assemble units on the ground. The unflipped matte silver aluminum frames showcase the essential geometric beauty of industrial design. Co-creation for a Sustainable Future This project not only provides clean energy but also demonstrates new possibilities for the industrial city. Grace Solar will continue to promote global decarbonization with excellent products and services.

The reason aluminum alloys are widely used in solar power generation projects is that they are lightweight yet strong, have excellent robustness, corrosion resistance, and oxidation resistance, and are easy to install. 1. Impact from heavy snow and strong winds? Based on conditions such as wind speed, snowfall, and installation angle in the installation area, structural calculations for the framework are performed in accordance with building load standards to meet design requirements. 2. Corrosion in humid areas? The corrosion resistance of aluminum frames can be improved by enhancing the plating process or increasing the plating thickness. For example, by applying processes such as anodizing, electrophoretic painting, and composite films, a protective layer is formed on the surface of the components. 3. Deformation due to extreme high temperatures? Thermal expansion is primarily affected by factors such as length and temperature. The longest members in the structure are the purlins, and by leaving gaps between the purlins during installation, structural failure due to thermal expansion can be prevented. 4. Uneven and unstable ground? The more accurate the environmental parameters provided during the design phase, the more stable the aluminum alloy frame will be after installation. For example, on uneven ground, the increase in wind load on slopes is calculated to ensure strength.

Under the sunlight of Ibaraki Prefecture, Japan, a group of "Metal Heroes" is rewriting the scenario of the new energy industry. As a key player in the region's solar power construction, Grace Solar supports the stable operation of multiple ground-mounted solar power plants in the prefecture with its uniquely developed aluminum ground mounting system. Our solutions are currently driving the "story of transformation" in the energy industry. The 6005-T5 aluminum mounting system specially developed by Grace Solar employs a dual protective coating of anodizing and powder coating, forming a dense protective layer on the surface. It maintains durability for over 25 years even in high salinity coastal environments. The patented ground screw, with its unique screw structure and surface treatment technology, ensures a strong bond with the soil while exhibiting excellent corrosion resistance against underground moist environments. In this new stage of development, Grace Solar is exploring further possibilities in Ibaraki Prefecture. The core philosophy is to "create maximum energy value with the smallest ecological footprint." From the initial pilot project to the current scale expansion, we are responding to the development of Ibaraki Prefecture through technological innovation.
