ASTM F1554 Grade 55 Anchor Bolt Manufacturer in Northville, MI

What Are F1554 Grade 55 Anchor Bolts?
ASTM F1554 Grade 55 anchor bolts are high-strength fasteners that play a vital role in securely connecting structural elements to concrete foundations. You’ll often find these robust bolts in commercial construction, infrastructure projects, and industrial applications, as they offer superior strength and durability where it matters most!
With a minimum yield strength of 55 ksi, these Grade 55 anchor bolts are an ideal choice, especially when a project demands higher load capacity and lasting performance.
At AA Anchor Bolt, Inc. in Northville, Michigan, we take pride in crafting custom F1554 Grade 55 anchor bolts tailored for contractors, fabricators, and engineers across a wide array of industries. We’re excited to support your projects with the quality you can trust!
Technical Specifications & S1 Weldability
Understanding the metallurgy of fasteners is crucial for project safety. F1554 Grade 55 is a modified mild carbon steel that offers an optimal balance of tensile strength and ductility.
-
Weldability (Supplementary Requirement S1): Standard Grade 55 is not universally weldable. At AA Anchor Bolt, we manufacture to the S1 supplement upon request. This involves a restricted chemical composition and a specific carbon equivalency formula to ensure structural integrity after welding.
-
Material Substitution: Per ASTM standards, a weldable Grade 55 (S1) can often be substituted for Grade 36 at the manufacturer’s discretion, offering a high-performance upgrade for your foundation.
Mechanical Properties of F1554 Grade 55
F1554 Grade 55 anchor bolts are manufactured from modified carbon steel and meet strict ASTM standards.
Key mechanical properties include:
-
-
Minimum Yield Strength: 55 ksi (380 MPa)
-
Tensile Strength Range: 75–95 ksi
-
Elongation: Varies by diameter
-
Reduction of Area: Designed for structural performance
-
Compared to Grade 36, Grade 55 provides higher strength and improved load-bearing capacity, making it suitable for more demanding structural applications.
Common Applications for Grade 55 Anchor Bolts
F1554 Grade 55 anchor bolts are essential in both commercial and residential construction, particularly for structural and infrastructure projects.
Typical applications include:
-
-
- Structural steel column anchoring
- Light poles and traffic signal mast arms
- Highway and Department of Transportation (DOT) projects
- Sign structures and strain poles
- Industrial equipment anchoring
- Foundation anchoring systems
- Sag rods and bracing systems
-
These applications require reliable anchoring performance, especially in environments exposed to heavy loads, vibration, or environmental stress.

Frequently Asked Questions: F1554 Grade 55 Anchor Bolts
No. Standard Grade 55 material is not automatically weldable. To ensure a safe, high-quality weld, you must specify Supplementary Requirement S1. At AA Anchor Bolt, we track the chemical composition and carbon equivalency of our S1-certified steel to guarantee it can be welded without structural embrittlement.
Grade 55 anchor bolts have a higher yield strength (55 ksi vs. 36 ksi), making them better suited for structural and load-bearing applications.
Yes. When paired with galvanized finishes, they perform well in outdoor and high-moisture environments.
HDG provides a thick, metallurgically bonded zinc coating that is far more durable than standard zinc plating. It is the preferred finish for Michigan infrastructure and DOT projects (such as mast arms and traffic poles) because it provides long-term protection against the corrosive effects of road salt and moisture.
