Welcome to STI Group USA

The Center of Excellence USA was initially focused solely on the defense industry and specifically on the chrome plating of the bores of medium and large caliber cannon. They now have taken the disciplined processes required to successfully serve this market and offer this same level of quality services to the paper & pulp, thin film & foil, composite material, power generation, oil & gas and many other industrial sectors.


Hartchrom Inc. has the capacity to handle part sizes up to 82 inches in diameter, 440 inches in length and up to 30 tons. With their three large chrome plating tanks, lead times for large components are kept to a minimum. Additional capacity is available for smaller parts and they offer electrocleaning, electropolishing, solid film lubricant application and phosphating services.
