Firstly metals like steel rust very quickly and so need some protection if to be used outdoors where they will get wetHow ever aluminium is different , when aluminium gets wet , it oxidises and forms a dull coatingThis corroded coating how ever protects the aluminium underneath it so no more corrosion occursThis leaves a dull finish but it is weather poof and will last for years and years in all weathers, 20 years plus ! The chairs in the photo have a dry powder finish - this is a process where you heat up the aluminium to about 350 centigrade and then blow powdered plastic on to the hot metalThis melts the plastic and you are left with a plastic coated aluminium chairIts just cosmetic really as i said aluminium will not rust or corrode as it forms a protective film naturallyPro - tec is just some sales jargon for a professional protection against corrosion but its rubbish sales talk and just a cosmetic finishThe chairs look nice but aluminium does not rust so the plastic protection is not required !
