USA F1554 Grade 55 S1 Threaded Rod, HDG (Inch)

Our USA‑manufactured F1554 Grade 55 S1 threaded rods with a hot‑dip galvanized (HDG) coating are engineered for structural anchoring applications that require superior strength, weldability, and long‑term corrosion protection. Meeting all ASTM F1554 requirements, these high‑strength rods deliver a minimum yield strength of 55 ksi and include the S1 weldability supplement, ensuring compatibility with welding applications where post‑installation attachments or modifications are necessary.

The HDG finish provides a thick, durable zinc coating for outstanding corrosion resistance in outdoor, coastal, and industrial environments. These rods are ideal for foundation anchoring, light poles, sign structures, highway construction, steel buildings, and other heavy‑duty applications where long‑term durability and code compliance are critical.
