Why QB
A partner trusted on projects that can't fail.
In transmission infrastructure, a single field failure can cost more than the entire fabrication contract. QB exists to eliminate that risk before steel ever ships.
Precision
Tight-tolerance fabrication held to utility specs across every weld, hole and member.
Risk Reduction
Trial assembly and documented QA/QC cut field rework before it can cost a schedule.
Responsiveness
39 years of West Coast emergency response, Oregon-based, not offshore.
Utility-Grade Quality
AWS D1.1 welding. ISO 9001:2015 principles. MBE-certified. Trusted by BPA, PGE, PacifiCorp and Burns & McDonnell.

Our Process
From raw steel to field-ready structures.
Fabrication
CNC drilling, cutting, and fit-up to utility specs.
AWS D1.1 Welding
Certified welders on every structural connection.
Trial Assembly
Verify fit and tolerance before shipment.
QA/QC & Delivery
Documented inspection and shipment-ready bundling.
The Differentiator
If it doesn't fit in our shop, it doesn't leave our shop.
Every major QB structure is trial-assembled before shipment: pre-built, measured, and verified, so the component that arrives on your site installs the way the drawings promise. Field failures don't begin in the field. They begin in fabrication shops that ship unverified steel. QB doesn't.
Founder Story
