The price of a gazebo is primarily driven by material durability and structural engineering. For metal gazebos, ensure the frame is powder-coated aluminum or galvanized steel to prevent rust. For wooden structures, pressure-treated cedar or redwood is preferred for rot resistance. Pay close attention to the roof load capacity (measured in lbs/sq.ft) and wind speed rating (ideally 50-70 mph), as these technical benchmarks directly correlate with the product's lifespan and safety in outdoor environments.
