Aluminium is treated with an electrolyte process which provides a tough oxydized coating protecting the aluminium from influences by salt- and freshwater.
Powder is spread on polished cast aluminium and stoved afterward for protection against aggressive atmospheres.
Stainless steel is a high-chrome steel with superior corrosion resistance. The main stainless steel grades are AISI 304 with good corrosion resistance and AISI316 with excellent corrosion resistance.
