One-Piece Bending Design: The 45 degree post bracket arch is manufactured using a rectangular steel tube stamping and forming process, with the entire tube bent into an arc shape. It allows easy installation without cutting wood. The seamless arc tube design combines aesthetics and practicality, providing stronger support for the wood beam.​ Heavy Duty Brackets: The pergola support brackets are thickened and reinforced, which can effectively prevent gazebos, patios or porches from shaking and tipping, ensuring long-term stable support for your outdoor post brace.​ Exquisite Craftsmanship: The surface of the pergola corner brackets is treated with outdoor high-temperature powder coating (black sand finish), which has excellent waterproof and rustproof performance. It can resist the erosion of rainwater, high temperatures and other outdoor environmental factors for a long time, extending the service life of the brackets and the connected wood components.​ Drainage Design: The 45 degree side support bracket is equipped with drainage holes at both ends, which can efficiently drain rainwater and snowmelt to avoid water accumulation inside the bracket. This design can prevent moisture from corroding the metal brackets and connected wood, further protecting the structural integrity of the outdoor wood frame.
