Our restoration process is set up to deal with aluminium furniture which comprises the majority of outdoor metal furniture sold. The other metal used in outdoor furniture is steel, much of which is low quality. Steel can rust badly and quickly and we have discovered over the years that no matter how well we treat this material in our restoration process, we cannot guarantee that the rust will not return. Since we give a 4 year warranty with our restoration process, we cannot restore steel furniture and give a warranty. These photographs show examples of outdoor steel furniture.
