Most of our chairs are manufactured in powder-coated steel frames. Our products are durable, nevertheless, the life of the finish will depend on the environmental conditions it is exposed to. The Purohierro line can be used in covered outdoor conditions and should not remain under the rain for long periods. After exposure to rain and dust, the structure should be dried with a cloth to reduce the chances of rust. If bumped or scratched, we suggest applying anti-corrosive paint of a similar color in the damaged area.
