FLAT CUT / METAL LETTERS
Stainless Steel Passivation
Contrary to conventional wisdom, most stainless steel alloys are not completely resistant to corrosion. For example, surface corrosion
can result from foreign residue generated by secondary finishing processes, subsequently becoming entrapped within the grain of the metal. When this residue comes into contact with moisture, undesirable surface blemishes and a costly repair or re-installation can be the result.
So that you and your client can avoid these sorts of headaches from surfacing in the field, we
put all of our flat cut stainless steel letters and logos through a rigorous “passivation” process. This in-house procedure removes any foreign surface contaminants, and at the same time creates a passive oxide layer that protects against unsightly surface corrosion. As a general rule, we highly recommend you consider having all of your stainless steel letters passivated for exterior applications.
You can rest assured, as part of our Lifetime Guarantee, all Gemini flat cut stainless steel letters and logos have been passivated, following ASTM A 967 and AMS 2700 standards.
