Through our tireless commitment to technological advancement, research and rigorous testing, our engineers have acquired an unparalleled body of expertise, with more patents and code-listed products than anyone else in the business. Our Yield-Link moment connection is precision-made to meet the tough demands and increased loads of structural steel construction. From building owners to engineers, to contractors and fabricators, the Yield-Link's state-of-the-art design saves everyone time and money — while providing a connection that keeps structural steel buildings strong and safe.
Key Features
- Saves time and costs on fabrication and erection
- Requires no onsite welding of moment connection, reducing welding inspection costs
- Replaceable Yield-Links allow for less costly repairs and shorter recovery times
- Accepted into AISC 358-22 and code listed in ICC-ES ESR-2802
- Can be integrated into your design software and can be designed without beam bracing
- Reduces difficult coordination between welders and inspectors
- No delays for field welding and welding inspection of the moment connection
- Small protected zone for easier MEP coordination
- All shop welds are fillet welds, providing a simple fabrication process

- Extended Yield-Link moment connections have longer yielding lengths offering the same axial capacity, but less stiffness as compared with the standard versions. Consider using extended Yield-Link moment connections when deeper beams are required due to longer Ly-link requirements, but additional moment capacity is not required.
- OSHPD/HCAI and DSA design projects require “YL” (Yield-Link configuration with separate/non-integrated spacer plates). All Yield-Link SKUs are offered in OSHPD/HCAI and DSA compliant “YL” configurations, unless noted otherwise.
- Yield-Link SKU are currently not prequalified for OSHPD/HCAI and DSA design projects.
- Yield-Link SKU are currently not available in Yield-Link configuration with integrated spacer plates.
