Halo Structural Products: Your Trusted Source for F1554 THREADED ROD Grade 55 Anchor Bolts

At Halo Structural Products, we specialize in manufacturing high-quality ASTM F1554 Grade 55 threaded rods and anchor bolts. These anchor bolts are crafted from a modified mild steel, offering a superior minimum yield strength of 55 ksi compared to the traditional A36 mild steel’s 36 ksi. This specification has been a cornerstone in the light pole and traffic signal industries long before the official ASTM F1554 standard was established in 1994, commonly referred to as A36M55. Just like Grade 36, Grade 55 anchor bolts cover diameters from 1/2″ to 4″.

Galvanizing Options for Threaded Rod Grade 55

Our F1554 Grade 55 anchor bolts are available in both black and galvanized finishes, ensuring durability and corrosion resistance for various applications.

Welding Considerations for Threaded Rod Grade 55

It’s a common misconception that all Grade 55 materials are weldable. For weldability, the supplementary requirement S1 must be specified. When weldability is crucial, Grade 55 may be substituted for Grade 36 at the supplier’s discretion. All Grade 55 round bars in our stock meet the S1 weldability standards.

Supplementary Requirements for Threaded Rod Grade 55

For customized needs, the following supplemental requirements can be specified in your purchase order or contract:

S1: Weldability

This requirement ensures weldability through specific chemical composition restrictions and a carbon equivalency formula. If not specified, the material may not be weldable.

S2: Permanent Manufacturer’s Identification

Instead of the standard yellow color-coding for Grade 55, this requirement mandates a permanent manufacturer's mark on the anchor bolt end projecting from the concrete.

S3: Permanent Grade Identification

Similar to S2, this requirement replaces the yellow spray paint with a permanent grade identification on the anchor bolt end.

S4: Charpy Impact Testing

This specifies Charpy impact testing at +40°F (+5°C), with a minimum Charpy V-notch energy requirement of 15 ft-lbs for three specimens, with no single specimen below 12 ft-lbs.

Material Substitution Warning for Threaded Rod Grade 55

Be cautious of fastener distributors and manufacturers with limited capabilities who might substitute 1045 round bar or A193 Grade B7 material for F1554 Grade 55. These materials might meet tensile and yield strength requirements but often fail to comply with elongation and reduction area standards. Grade 55 round bar is not commonly found in local warehouses, but Halo Structural Products sources mill runs of round bar to keep a steady inventory for immediate processing.
