ASTM F1554 Grade 55 All Thread Rods with Plain Finish
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 – Plain Finish
High-Strength Anchor Rods for Structural and Infrastructure Applications
ASTM F1554 Grade 55 all thread rods with a plain finish are engineered for medium to heavy-duty anchoring in concrete and structural foundation applications. With a higher yield strength than Grade 36, these rods are ideal for buildings, bridges, light poles, traffic structures, and other infrastructure requiring increased load capacity and reliability.
What Is ASTM F1554 Grade 55?
ASTM F1554 specifies threaded steel rods used as anchor bolts embedded in concrete. Grade 55 indicates a medium-strength, low-alloy steel with a minimum yield strength of 55,000 psi, making it suitable for more demanding structural applications than Grade 36.
Many Grade 55 rods are available with supplementary S1 weldability certification, ensuring they are safe for use in welded assemblies without risk of brittleness or failure.
Benefits of Plain Finish
The plain (uncoated) finish offers advantages for specific environments and fabrication needs:
-
✅ Ideal for indoor or dry, protected environments
-
✅ Allows for custom coatings such as galvanizing or epoxy after fabrication
-
✅ Better torque control where finish thickness can impact clamping force
-
✅ Cost-effective for large-scale projects without corrosion risk
Sizes and Common Applications
Grade 55 plain finish all thread rods are typically available in diameters from 1/2" to 2-1/2" and lengths up to 12 feet, with custom cuts and threading available. Common uses include:
-
Foundation anchoring for buildings and bridges
-
Light pole and sign structure supports
-
Wind turbine and utility installations
Reliable Strength for Structural Anchoring
When projects demand a strong, weldable, and affordable anchor solution, ASTM F1554 Grade 55 all thread rods with plain finish deliver the performance and flexibility engineers and contractors trust.
