ASME U-stamp fabricators

Required to build coded pressure vessels. Non-negotiable when it applies.

9 shops state they hold ASME U-stamp. Each entry below shows the sentence we read it from, on the shop's own website — we don't record a certification we can't quote. Confirm current status with the shop or the certifying body before you award work.

We hold an unlimited, unclassified general contractors license, along with mechanical and electrical trade licenses in multiple states. We are an AISC Certified fabricator for building steel, bridge component steel, and sophisticated paint. With ASME A, S, U and PP stamps, and a National Board R stamp, we are experienced in the construction, fabrication, and repair of boilers, power piping, and pressure vessels.https://edwardsinc.com/about-edwards
