Our Commitment to Quality
C4 Welding is built on a foundation of quality in everything we do–from customer service to precision machining to critical welding and more. Quality is our highest priority, and we take several measures to ensure that each of our customers receives the highest quality for the best value.
Testing & Inspection for Quality Metal Fabrication
C4 Welding offers a wide range of proactive, non-destructive testing capabilities to ensure our fabrications and welds are up to the job! Each is conducted by an experienced and trained quality inspector and performed onsite or in-house on request.
