Custom Fabrication of Stainless Steel I-Beams

Overcome the cost and availability hurdles of mill stainless steel I beams. Standard stainless structural sections are often incredibly expensive with long lead times, especially in specialized grades like 316/316L, Duplex alloys, or other high-nickel alloys. Northern Manufacturing provides a superior alternative: custom-fabricated stainless steel i beam, built to your exact specifications using our advanced robotic welding and laser cutting technology.

The Strategic Advantage of Fabricated Beams

For procurement managers and project engineers, sourcing stainless steel i-beams presents a constant battle between cost, lead time, and material specifications. Custom-fabricated beams from Northern Manufacturing directly address these core challenges.

Cost & Lead Time Reduction

Avoid the premium prices and long waits associated with specialty milled beams. Our process uses readily available stainless steel plate and sheet, which we then laser cut and robotically weld, significantly reducing costs and shortening delivery schedules.

Material Flexibility

Are you struggling to find beams in Duplex 2205, AL-6XN, or Hastelloy? Our fabrication process is material-agnostic. We can create custom beams from the exact high-performance alloy your project demands, from 304L and 316L to exotic grades.

Total Design Freedom

You are no longer limited by standard sizes. We manufacture beams to your precise height, flange width, and web thickness, enabling optimized engineering without compromise. This is the definition of a one-stop-shop for custom fabrication.

Custom Stainless Steel I-Beam Advantages

Automation Reduces Costs

Welders are currently in short supply in the workforce. Robotic welding allows one programmer to match the output of more than 3 welders, across multiple robots and multiple shifts.

High Productivity

Our weld cycle times are often limited by how fast we can load parts into the Robot cell and hit GO. Setups often involve multiple weld fixtures for each robot, so that the robot can keep welding while parts are loaded and unloaded parallel to production.

Improved Weld Quality

Laser vision systems allow us to push robotic weld quality to new levels. Robots have always made consistent welds, but the weld quality was only as good as the consistency of the parts entering the weld cell. No longer are robots blind and dumb. The laser vision system allows the robot to adapt the weld path to match the part tolerances, eliminating weld rework.

High-Speed Laser Cutting

It starts with our 12,000-watt Trumpf FiberLaser. We cut the web and flanges from your specified material grade with a typical tolerance of +/- 0.005″, ensuring perfect fit-up for welding.

Robotic Welding Cells

The components are then moved to one of our 5 robotic welding cells. Our AWS-certified procedures ensure deep, full-penetration welds that are consistent and verifiable, creating a monolithic piece with exceptional strength.

Quality & Inspection

Every fabricated beam is backed by our ISO 9001:2015 certified quality system. We can provide a complete documentation package, including:

  • Laser Seam Tracking for reliable weld quality
  • Material Test Reports (MTRs) for full traceability
  • AWS D.16 WPS and WPQ
