You need a single source for your high-quality stainless steel components and fabrication needs; we have it under one roof. Our proven manufacturing processes ensure you get the quality, documentation, and support to get projects done on time, within budget, and meeting any demanding quality requirements.

Project Management

Every project has quality assurance built in from the start and is managed by an experienced project manager. By communicating with our customers and performing a complete contract/specification review up front, we develop a quality and manufacturing plan that meets the requirements of the project. That way the correct checks and inspections are performed at the proper time in the manufacturing process, eliminating surprises at the end.

Quality, Testing & Inspection

Your most demanding quality requirements can be met with our proven team of experienced quality engineers and manufacturing professionals. Our project managers understand the rigors of quality programs, testing procedures, and inspection techniques.
