Fabrication

Sterling has established a strong niche in the market by specializing in stainless steel fabrication.

We have dedicated our 35,000 square foot facility to the specific requirements of stainless steel and non-ferrous alloy fabrication. Sterling utilizes the latest technology in forming, welding, and polishing. We have trained artisans who know the intimate details of fabricating, welding and polishing stainless steel, as well as other nickel alloys. Their attention to detail is an integral part of every project that passes through our quality control inspections.
