Why are cast iron outdoor chairs less suitable for use in coastal regions?

Cast iron outdoor chairs, while sturdy and aesthetically pleasing, are often less suitable for coastal regions due to their susceptibility to rust and corrosion. The high salt content in coastal air accelerates oxidation, causing cast iron to deteriorate faster than in inland areas. Frequent exposure to moisture, sea spray, and humidity further exacerbates the problem, leading to peeling paint, structural weakness, and unsightly rust stains.

Additionally, cast iron requires regular maintenance, such as sealing and repainting, to withstand coastal conditions—a time-consuming effort many homeowners prefer to avoid. For beachside or seaside environments, materials like aluminum, teak, or synthetic wicker are better choices, as they resist saltwater damage and require minimal upkeep.

If you must use cast iron near the coast, opt for powder-coated or galvanized variants and store chairs indoors during harsh weather. However, for long-term durability, alternative materials are often the wiser investment.
