For the Design Engineer: Guaranteed Performance & Flawless Execution

We understand that for Design Engineers, flawless execution is paramount. A fabrication that fails to meet spec reflects on your design and causes costly delays. Our team thrives on technical challenges, ensuring your designs are translated from print to physical reality with absolute precision.

  • Material & Welding Excellence: We have deep, verifiable experience with 304L, 316L, and Duplex stainless steels (2205, 2507).
  • Surface Finishing & Corrosion Control: Our in-house pickling and passivation capabilities are critical for restoring the steel’s passive layer, ensuring maximum corrosion resistance and longevity in harsh environments.
  • Advanced Manufacturing: We leverage technology like 5-axis laser cutting, robotic welding, and 3D model-based inspection to ensure your components are built exactly to spec, every time.

Frequently Asked Questions

We combine three critical elements: material expertise, certified processes, and proper surface treatment. We use qualified welding procedures (WPS) compliant with AWS and ASME standards, executed by over 60 certified welders and verified by our on-staff CWI. After welding, we perform pickling and passivation to ASTM A380 standards to remove contaminants and restore the steel’s natural corrosion-resistant passive layer.

Yes. We have specific expertise in fabricating Duplex stainless steels, including grades 2101, 2205, and 2507. We understand the critical requirements for controlling heat input during welding to maintain the proper ferrite-austenite balance, which is essential for preventing corrosion and ensuring the material’s superior strength and performance.

very project is supported by a comprehensive documentation package to ensure full traceability and compliance. This typically includes a Certificate of Conformance (CofC), full Material Test Reports (MTRs) for all alloys used, and reports for all special processes, including weld maps, NDT reports, and passivation certifications, all managed under our ISO 9001:2015 certified QMS.
