Anchor rods are threaded fasteners embedded in concrete foundations to provide stability and support for structural steel columns, light poles, traffic signals, highway signs, and industrial equipment. They resist tension and shear forces, securing superstructures to foundations in construction and manufacturing applications.
Available in cast-in-place and post-installed configurations, anchor rods include straight rods, L-shaped or J-shaped bent bolts, and fully threaded rods. Customization options include forged heads, swedged ends, or epoxy bonding. The embedded end features nuts, plates, forged heads, or epoxy to prevent pullout, while the projecting threaded end uses nuts and washers to secure attached structures.
Specifications follow standards like ASTM F1554 (grades 36, 55, and 105, with yield strengths of 36 ksi, 55 ksi, and 105 ksi), ASTM A449, A354, A193, and A320. Materials range from carbon steel to stainless steel alloys (304 and 316), with diameters from 1/2 inch to 6 inches. Finishes include hot-dip galvanizing or zinc plating for corrosion resistance.
Manufacturing involves cutting steel round bar, threading, and operations like forging, swedging, or welding. Accessories include nuts, washers, anchor plates, coupling nuts, and sleeves. For post-installed systems, adhesive capsules or injectable hybrid epoxy mortars bond rods in pre-drilled holes, enabling retrofitting in existing concrete structures.

Frequently Asked Questions（FAQS）
What are anchor rods and what are they used for?
Anchor rods are threaded fasteners embedded in concrete foundations to support structures such as light poles, traffic signal poles, structural steel columns, highway sign structures, and industrial equipment. They resist tension and shear forces, providing stability and strength across construction, highway projects, marine applications, power generation, and infrastructure like wind farms and solar structures.
What types and configurations of anchor rods are available?
Anchor rods come in various configurations including straight rods, bent anchor bolts (L-shaped or J-bolts), headed bolts, all thread rods, and swedged rods. They are available in multiple diameters, lengths, and thread types, with options for carbon steel, alloy steel, or stainless steel (304 or 316). Custom solutions can include anchor plates, sleeves, or special bends tailored to engineering specifications.
What ASTM specifications are common for anchor rods?
Common ASTM specifications include F1554 (with grades 36, 55, and 105 indicating minimum yield strength), A307, A449, A354, A193, A320, and F593 for stainless steel. F1554 is specifically designed for anchor bolts, while others like A193 are used for high-temperature or corrosive environments.
How are anchor rods installed in concrete?
Anchor rods can be cast-in-place during concrete pouring using positioning templates, or post-installed in existing concrete. Post-installation involves drilling holes, cleaning, and inserting the rod with epoxy, adhesive capsules, or injectable mortars for a secure bond.
What corrosion protection finishes are available?
Finishes include plain steel, hot-dip galvanized, zinc-plated, and other coatings to enhance corrosion resistance for outdoor, marine, or harsh environments, ensuring durability and longevity.
Do your anchor rods meet international standards for reliability?
Yes, we manufacture anchor rods to various ASTM specifications, including F1554 Grades 36, 55, and 105, ensuring extreme product reliability and full compliance for critical applications such as utility grid maintenance where certified hardware is essential.
