Serving the West Coast
& Mid-West USA

Sigma's in-house lab enables us to quickly monitor our process before, during, and after tank usage to minimize disruption and significantly increase productivity.

We run a 24-hour operation, on automated lines that allow us to efficiently produce your project needs in the shortest possible time frame and at the best possible price.

Every project undergoes chemical testing by strict guidelines for quality control, which includes pre and post production inspection by established finish standards. Sigma firmly upholds its quality standards and concurrently reinforces our customer confidence in our top quality service.
