ASTM F1554 Class 55 All Thread Rods with Hot Dipped Galvanized Plating
Freight Policy for Items 3 Feet in Length and Longer
Oversized Item Shipping Guidelines
Items 3 feet in length and longer do not qualify for free freight, even if the order meets the standard free freight threshold. These oversized products are excluded from free freight calculations and will be shipped at current UPS published rates.
Items Over 6 Feet
Products longer than 6 feet require truck freight shipment. Freight charges will be calculated after the order is received and submitted for customer approval prior to shipment. These items are also excluded from free freight qualification and free shipping promotions.
ASTM F1554 Grade 55 All Thread Rods – Hot-Dip Galvanized
High-Strength, Corrosion-Resistant Anchors for Structural Foundations
ASTM F1554 Grade 55 all thread rods with hot-dip galvanized (HDG) plating offer the ideal combination of strength and corrosion resistance for anchoring in outdoor, exposed, or concrete-embedded environments. These rods are commonly used in bridge construction, light poles, sign supports, utility infrastructure, and structural steel connections.
What Is ASTM F1554 Grade 55?
ASTM F1554 Grade 55 defines medium-strength steel anchor rods with a minimum yield strength of 55,000 psi, designed for anchoring structural elements to concrete. These rods are often available with the S1 supplement for weldability, ensuring they can be safely welded without compromising performance.
As fully threaded rods, they allow for flexible installation with standard hex nuts, couplers, and washers, making them a go-to choice for custom anchoring systems.
Advantages of Hot-Dip Galvanized Finish
The hot-dip galvanized coating provides superior corrosion protection through a thick, zinc-based barrier that chemically bonds to the steel. Benefits include:
-
✅ Excellent protection in wet, coastal, or chemically exposed environments
-
✅ Ideal for embedded concrete and outdoor structural applications
-
✅ Long service life with minimal maintenance
-
✅ Meets or exceeds ASTM F2329 and A153 coating standards
Sizes and Applications
Available in diameters from 1/2" to 2-1/2" and lengths up to 12 feet, hot-dip galvanized Grade 55 all thread rods are commonly used for:
-
Structural steel anchoring
-
Traffic signal and light pole foundations
-
Wind turbine bases and bridge supports
Built to Withstand the Elements
For reliable, high-strength anchoring in corrosive or outdoor conditions, ASTM F1554 Grade 55 all thread rods with hot-dip galvanized plating provide unmatched durability and long-term performance.
