The most common materials used in metal gazebo construction include aluminum and steel. Aluminum is lightweight, resistant to rust, and relatively low maintenance, making it a popular choice for metal gazebos. Steel is durable and strong, making it suitable for larger or more heavy-duty gazebos, but it may require more maintenance to prevent rust. Domi has various options, including steel gazebo, polycarbonate gazebo and wood gazebo. Each material has its own advantages and considerations, so it's important to choose one that fits your specific needs and preferences.
