[High Quality] The bracket is made of aluminum alloy, with sleek (non-sharp) edges and rust resistance, making it ideal for uneven surfaces. Extremely sturdy and durable, it does not bend easily. This roof solar panel bracket can be installed in hot, cold, or humid environments. [Practical Design] The grooved design of this stamped aluminum alloy solar panel bracket ensures secure attachment to the solar panel. The exterior of the side-stamped photovoltaic bracket is precisely stamped and polished, making it a very practical mounting bracket. [Easy Installation] Our solar panel bracket kit includes 8 sets of aluminum alloy photovoltaic brackets. They are easily installed without removing screws, saving considerable time and providing greater convenience. Lightweight and sturdy: Unlike stainless steel solar brackets, our corrosion-resistant aluminum alloy brackets are lighter but stronger, providing better support for solar panels without adding weight to the roof. They withstand various weather conditions and harsh environments, and have a long service life. [Multipurpose Use] Solar panel brackets are mainly used to fix solar panels to rails and ensure a strong connection between them. They are suitable for high and sloped roofs made of tiles, asphalt shingles, flat tiles, and vertical metal panels, allowing for quick installation of photovoltaic solar panels.
