Yes, both Corten steel and powder-coated aluminium outdoor wall art are designed to be waterproof and weather-resistant.
Corten steel, in particular, is highly resistant to weathering and corrosion thanks to the protective patina that develops on the surface of the metal. This patina helps to protect the steel from further corrosion and deterioration, making it an ideal material for outdoor use.
Powder-coated aluminium is also highly resistant to weathering and corrosion. The powder coating process involves applying a dry powder to the aluminium and then heating it to create a hard and durable finish. This coating helps to protect the aluminium from weathering and corrosion, making it a great option for outdoor use.
