• Preferably bases of pedestals are fastened with stainless steel screws

Stainless steel screws have a tendency to seize. A small amount of grease applied to the screws before they are fixed will help prevent this happening.
To avoid electrolytical effects (ss screws on casted aluminium + saltwater) we recommend Tef-Gel.
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.
