Sterling Armor® is turning the stainless steel and plated ball world upside down. An inexpensive alternative for both load bearing and non-load applications. Our exclusive patented manufacturing process controls time, temperature and gaseous composition defusing corrosion protection into the microstructure of the steel creating a superior scuff and wear resistant surface. Sterling Armor is unaffected by UV exposure, and is ideal for caustic environments. It provides a complete and uniform barrier capable of withstanding 24, 48, or 96 hour salt fog testing.
