Outdoor furniture is generally made of different kinds of materials, such as metal, wood and plastic. The metal is an obvious choice since it provides greater durability and functionality. Most of the metal furniture comes with the rust-resistant coating. On the other hand, the wood is also used as the material of the outdoor furniture. Teak is considered as most used wood which has natural protective oil, which makes the furniture water resistant.
You are supposed to go for the plastic furniture if you are on a tight budget.
Apart from these, plastic is also used in outdoor furniture.
