Stainless Steel: Alloys 304 & 316
(1/8”, 1/4”, 3/8” & 1/2” Thick)
STAINLESS STEEL FINISH NOTES:
ALLOY 304: The standard “18/8” stainless; it is the most versatile and most widely used
stainless steel. For areas within 50 miles of the coast, Gemini recommends Alloy 316
ALLOY 316: 316 offers better overall corrosion resistant properties than 304, particularly
higher resistance to pitting and crevice corrosion in chloride environments.

Cor-Ten®
1/8” & 1/4” Only
Cor-Ten:®: An environment resistant steel, created by alloying copper, chromium and nickel.
The material forms its own continuing protective rust layer, when exposed to atmospheric
elements. Essentially, the top layer corrodes, which then protects the steel beneath it – hence
Cor-Ten cannot be painted or clear coated, as it will push off most surface surfactants over time.
It is not recommended for mounting on any surface that could be stained, due to the bleeding
of this rust layer.
POLISHING: Requires a minimum of .5” stroke at 1/8” thick (stud weld required). Restrictions
may apply on letters/logos over 24”.
