The ASTM F1554 Grade 55 Anchor Rods specification was introduced in 1994 and covers anchor bolts designed to anchor structural supports to concrete foundations. ASTM F1554 Grade 55 Anchor Rods can take the form of either headed bolts, straight rods, or bent anchor bolts. The three grades 36, 55, and 105 designate the minimum yield strength (ksi) of the anchor bolt. ASTM F1554 Grade 55 Anchor Rods can be either cut or roll threaded and a weldable grade 55 can be substituted for grade 36 at the supplier’s option. Color coding on the end – 36 blue, 55 yellow, and 105 red – helps facilitate easy identification in the field. Permanent manufacturer and grade marking is allowed under the S2 supplementary requirements.
Applications for ASTM F1554 Grade 55 Anchor Rods include columns in structural steel framed buildings, traffic signal and street lighting poles, and overhead highway sign structures to name just a few.

Manufacturing Process of ASTM F1554 Anchor Rods:
YOKELINK ASTM F1554 Grade 55 Anchor Rods are manufactured through a controlled production process to ensure compliance with ASTM F1554 requirements for dimensional accuracy, mechanical performance, and corrosion resistance.
Raw Material Inspection → Cutting → Forming & Bending → Thread Rolling → Heat Treatment (Grade 105) → Hot Dip Galvanizing → Quality Inspection → Packaging & Shipment.
1. Raw Material Inspection
High-quality carbon steel and alloy steel materials are selected according to the required grade. Chemical composition and material certificates are verified before production.
2. Cutting
Steel bars are cut to the specified lengths using precision cutting equipment to ensure dimensional consistency.
3. Forming & Bending
Anchor rods are formed into the required configurations, including straight rods, double-end threaded rods, J-type rods, and L-type rods, according to project specifications.
4. Thread Rolling
Threads are produced by thread rolling machines to achieve precise thread dimensions, improved surface finish, and enhanced mechanical strength.
5. Heat Treatment (For Grade 105)
Grade 105 anchor rods are quenched and tempered to achieve the required mechanical properties and high-strength performance.
6. Hot Dip Galvanizing
Anchor rods can be hot dip galvanized in accordance with ASTM F2329 or ASTM A153 standards to provide long-term corrosion protection in outdoor environments.
7. Quality Inspection
Each batch undergoes comprehensive inspection, including dimensional verification, thread gauge inspection, mechanical testing, coating thickness measurement, and visual examination.
8. Packaging & Shipment
Finished products are securely packed on pallets, in wooden crates, or according to customer requirements to ensure safe transportation and delivery.
