For the mounting systems: The F101 fixed flat roof mounting system is constructed with high-strength 6005/6063 aluminum alloy, offering both lightweight and corrosion-resistant properties. Its scientifically optimized 10° tilt angle balances power generation efficiency and structural stability, while the modular pre-assembly design reduces construction time by 40%. No heavy lifting equipment is required, significantly cutting labor and time costs. The F102 adjustable flat roof system provides flexible tilt angle options from 10° to 15°, allowing optimization based on local sunlight conditions and compatibility with most framed and frameless solar panels. Its roof-friendly engineering distributes loads evenly to protect waterproof layers, making it ideal for commercial and industrial buildings such as factories, shopping malls, and office buildings. For harsh environments, BTC's U-steel series mounting systems leverage optimized section mechanical design, delivering 2.5 times the bending resistance of angle steel brackets of the same thickness. With a rated load capacity of 80kg over a 3-meter span, these systems can withstand level-13 typhoons and heavy snow loads. Certified to operate stably in extreme temperatures ranging from -40℃ to 80℃ with a service life exceeding 30 years, they completely resolve industry pain points such as insufficient load capacity, corrosion vulnerability, and high failure rates of traditional brackets.
