The material option for the pergola depends on your project style. The material you choose for the pergola should complement the surrounding style. Pergola structures are usually made of wood, iron, plastic vinyl, metal aluminum, or wood aluminum.
Material iron may rust and requires yearly maintenance by galvanizing or repainting to prevent rust. Wood is a common material for home/garden pergola. Teak, oak, redwood, and cedar are usually used as pergola material. Wood brings people a warm and natural feel to a space. This is also why people love wood grain so much in architectural and interior use. But material wood runs a high risk of rot, mold, and bugs and requires proper and regular maintenance. Material plastic vinyl is a resistant material for the pergola. Plastic pergola is suitable to be built close to a water fountain. It is relatively cheap compared with wood and metal, and it is also easy to maintain and clean. But strength is not so good. The plastic pergola provides limited colors, generally white or beige.
Now wood grain aluminum is recommended for commercial pergolas. It looks like natural wood, but actually, it is a strong metal aluminum frame, and it can withstand extreme weather than solid timber. It lasts for a long time and requires no maintenance. It is nearly the best choice for a large commercial pergola project. Some sophisticated pergolas have louvered roofing. The rotating blades can open and close for daylight control. So wood grain aluminum pergola is the trend of a modern pergola. Wood grain Aluminum pergolas provide a sturdy metal structure frame and a natural and elegant wood appearance. If you are looking for a good quality pergola, a wood grain aluminum pergola is best.
