Our Experience Works for You
With over 50 years of experience in finishing components and equipment, CSI is the leader in providing this service for the sanitary process industry. We are actively involved in organizations like 3-A and ASME BPE. Our active involvement allows us to incorporate the latest standards into our surface finishing process to meet the needs of our customers.
Cleanliness in Mind
Similar to our work stations, the polishing area at CSI is uniquely designed to be clean, safe, and efficient. The polishing department is in a separate area from our production area. The space has its own climate-controlled ventilation and filtration system that helps keep dust contained.
Every finished product goes through a detailed final inspection process to ensure it meets finish specifications and dimensional tolerances.
We make the success of your project a priority at CSI. Our finishing experience helps us meet your quality requirements.
