Surface Preparation and Coatings

Unlike mild steel the chemistry of stainless steels means the processes and methods for protecting and finishing 304 Grade Stainless Steel are vastly different to mild steels.  Most surface finishes for stainless steel will be mechanically (Polishing) or chemically (Passivating) applied.    The correct surface finish will have substantial impacts on the performance and appearance of your stainless steel.   

One of the most important considerations for the performance and appearance Stainless Steels is cleanliness.  Surfaces need to be kept free from particles of other metals especially alloy or carbon steels.  Timber also has contaminants that will leech and stain stainless steels.

Due to the variety of finishes available in stainless steels, Edcon Steel strongly recommends you discuss your requirements with your designer or fabricator.
