Atlanta Rod and Manufacturing is a leading domestic manufacturer of heavy-duty ASTM F1554 anchor bolts for critical structural foundations, heavy highway infrastructure, power generation, and commercial construction projects nationwide. From our ISO 9001-certified manufacturing facility in Lavonia, Georgia, we produce straight anchor rods, bent anchor bolts, headed bolts, and custom concrete embedment assemblies engineered to exact project specifications.
Every ASTM F1554 anchor bolt produced by Atlanta Rod is 100% melted and manufactured in the United States, providing complete traceability, full Certified Material Test Reports (CMTRs), and total compliance with the Build America, Buy America Act (BABA), the Buy American Act, and American Iron and Steel (AIS) provisions.
Complete ASTM F1554 Material Grades
The ASTM F1554 specification covers steel anchor bolts intended for anchoring structural supports to concrete foundations. We precision-manufacture anchor bolts across all three ASTM F1554 grades to satisfy structural engineering calculations:
- ASTM F1554 Grade 36: Manufactured from low-carbon, highly ductile structural steel with a minimum yield strength of 36 ksi (tensile strength 58–80 ksi). Grade 36 is weldable and widely utilized in light commercial foundations, building columns, equipment pads, and standard structural anchoring.
- ASTM F1554 Grade 55: Manufactured from high-strength, low-alloy carbon steel offering a minimum yield strength of 55 ksi (tensile strength 75–95 ksi). Grade 55 is the standard specification for Department of Transportation (DOT) applications, highway sign structures, traffic signals, and bridge retrofits. Atlanta Rod routinely supplies Grade 55 with Supplementary Requirement S1 (Weldability) to ensure field modification capability.
- ASTM F1554 Grade 105: Heat-treated, quenched and tempered alloy steel providing a minimum yield strength of 105 ksi (tensile strength 125–150 ksi). Grade 105 is engineered for heavy structural loads, seismic anchorages, wind turbines, overhead sign gantries, and transmission towers where maximum tensile and shear resistance are mandatory.
Custom Configurations & Manufacturing Range
Atlanta Rod specializes in custom fastener manufacturing, ensuring contractor requirements are met with precision threading, custom bends, and heavy embedment plates:
- Diameter Range: 1/2″ to 4-1/2″ (and metric equivalents up to M100).
- Straight Anchor Rods: Double-end threaded rods or fully threaded rods designed for use with heavy hex nuts and bearing plate embedments.
- Bent Anchor Bolts: Precision cold-bent 90-degree L-bolts, hook bolts, and J-bolts cold-formed up to 4″ diameter without structural compromise.
- Headed Anchor Bolts: Hot-forged domestic heavy hex heads and square head bolts for high-capacity pullout resistance.
- Swedge Bolts: Indented anchor rods engineered for bridge bearings and DOT precast embedments requiring elevated pullout load capacities.
- Threading Options: Precision rolled threads (for superior fatigue resistance and grain flow) and single-point cut threads. Available thread styles include UNC Coarse, UNF Fine, 8UN Series, Metric, ACME, and Left-Hand configurations.
Corrosion-Resistant Finishes & Protective Coatings
To endure harsh outdoor, coastal, and chemical environments, Atlanta Rod offers comprehensive finishing and corrosion protection services:
- Plain / Black Steel: Clean, uncoated finish for interior dry applications or non-corrosive concrete encasement.
- Hot-Dip Galvanizing (HDG): Fully compliant with ASTM F2329 and ASTM A153 Class C, providing thick sacrificial zinc metallurgical protection for DOT, marine, and exterior substations.
- Zinc Electroplating: Applied per ASTM B633 for clean aesthetic finish and light indoor corrosion resistance.
- Specialty Protective Coatings: Fluoropolymer (PTFE / Xylan), ceramic coatings, and epoxy treatments for aggressive chemical and subsea industrial environments.
Certified Compliance & Rapid Concrete Pour Delivery
Construction deadlines demand fast lead times and dependable material certifications. When foundation contractors face scheduled concrete pours, Atlanta Rod provides rapid emergency turnarounds and dedicated logistics:
- 100% Domestic Traceability: All steel billets, bar stock, and forgings originate from certified domestic steel mills with full melt and manufacturing documentation.
- DOT & BABA Certified: Pre-approved for federal, state, and municipal infrastructure projects under FHWA, FAA, and USACE guidelines.
- In-House Quality Control: ISO 9001-certified quality management, in-house dimensional verification, hardness testing, tensile testing, and Charpy impact testing (Supplementary Requirement S4).
- Complete Fastener Packages: We forge and supply matching domestic ASTM A563 heavy hex nuts, ASTM F436 hardened washers, and ASTM A36 / A572 anchor base plates from a single domestic manufacturer.
