Which hardwood is characterized as tough, heavy, and durable outside?

The hardwood that is characterized as tough, heavy, and durable outside is oak. Oak is well-known for its strength and resilience, making it suitable for outdoor use in furniture and construction. It possesses a natural resistance to moisture and decay, which is particularly important for items exposed to various weather conditions.

Cedar, while also durable, is a softer wood and is more recognized for its aromatic properties and natural resistance to insects and decay rather than the heavy, tough characteristics of oak. Mahogany is prized for its beauty and workability, but it is not necessarily known for being heavy or for its durability against the elements compared to oak. Maple is a hard wood often used for furniture and flooring; however, it is not typically utilized for outdoor applications as effectively as oak due to its susceptibility to moisture damage.
