Living by the coast offers beautiful views and a refreshing breeze, but the salt-laden air can be brutal on outdoor furniture. To ensure your benches withstand the harsh marine environment, selecting the right materials is crucial. The best choices are those that inherently resist corrosion.
Marine-grade aluminum is a top contender. It is lightweight, strong, and has a protective oxide layer that fights rust. For maximum durability, look for powder-coated finishes. Another excellent option is stainless steel, particularly grade 304 or the more corrosion-resistant grade 316, often called "marine-grade" stainless steel. Its non-porous surface makes it ideal for constant exposure to salt and moisture.
For a low-maintenance and completely rust-proof solution, consider benches made from High-Density Polyethylene (HDPE) lumber. This material, often made from recycled plastics, is impervious to salt, rot, and insects. It never needs painting and can be easily cleaned with soap and water. Teak wood is a classic, high-end choice due to its natural oils that repel water and resist decay. However, it will eventually weather to a silvery-gray patina and requires periodic oiling if you wish to maintain its original honey color.
Avoid materials like standard steel, cast iron, and untreated woods, as they will quickly succumb to rust and rot in a salt-air environment. By investing in benches made from these recommended materials, you can create a durable and inviting outdoor space that endures the coastal elements for years to come.
