Grade 55 Threaded Rod
When the job calls for concrete anchoring with strength and weldability, Grade 55 threaded rod answers. Developed for structural work, DOT infrastructure, and commercial steel anchoring, this rod offers the performance specs crews count on, plus the flexibility to modify in the field without breaking compliance.
It’s made to meet ASTM F1554 Grade 55 standards, giving you a minimum yield strength of 55,000 psi and a tensile range that can handle real structural loads. Whether you're setting deep anchors for pole bases or fabricating welded assemblies on-site, Grade 55 gives you holding power and the ability to adjust on the fly.
When should you use Grade 55 Threaded Rod?
- F1554 Certified: Ready for structural work where specs matter, anchors, plates, columns, and bridge supports.
- Field-Weld Capable: With weldable chemistry included, you can fabricate on-site without compromising strength.
- Performance Backed: 75-95 ksi tensile range, with 55 ksi minimum yield strength, enough for serious structural applications.
- Finish Flexibility: Available in plain (indoor use), zinc-plated (light protection), or hot-dip galvanized (for exposure or concrete embedment).
Applications in the Field
- Bridge deck supports and foundation anchors
- Steel column and base plate connections
- Sign poles, light poles, and barrier systems
- Any public or private job calling for ASTM-grade threaded rod with field weld compatibility
Install Notes
Grade 55 rods are typically fully threaded unless otherwise noted. Always use spec-matched nuts and washers to maintain structural ratings. For outdoor or embedded use, choose galvanized finishes to prevent corrosion and ensure long-term durability.
For welds, verify your certs and follow standard welding practices, this rod is engineered for it. When dealing with exposed hardware, make sure all components are finish-compatible to avoid additional corrosion.
