Hemaokang Steel (Shandong) Co., Ltd. proudly supplies high-quality deformed steel bars engineered for demanding infrastructure roles. Our ASTM A615 Grade 60 25mm deformed steel bar is a robust solution for bridge decks and pier foundations, delivering reliable strength and consistent performance in critical load-bearing structures. Manufactured with precision and backed by factory-direct supply, this rebar is designed to meet the practical demands of modern construction while ensuring durability and ease of use on site.
With an export value reaching US$50-100 million annually and serving markets across North America, South America, Europe, Southeast Asia, Africa, and Oceania, we understand the global standards for construction materials. Our steel bars are produced under a certified ISO9001 quality management system, offering you consistent quality and dependable supply from our base in Liaocheng, Shandong.
This deformed bar features a 25mm nominal diameter and conforms to ASTM A615 Grade 60, delivering a minimum yield strength of 420 MPa. It is the preferred choice for projects requiring enhanced bond performance with concrete, superior crack control, and excellent structural integrity. Below, we outline the technical profile and the value it brings to your projects.
- High Strength-to-Weight Ratio: Grade 60 is optimized for modern structural design, minimizing steel consumption without compromising safety.
- Superior Bonding: Deformed ribs provide a strong mechanical interlock with concrete, reducing slippage and increasing structural stability.
- Crack Control: Helps distribute tensile stresses evenly, reducing the risk of cracks in bridge decks and foundations.
- Workability: Designed for easy cutting, bending, and tying, simplifying on-site installation.
- Fabrication Flexibility: Available in standard lengths of 6m, 9m, 12m, and custom cut lengths to match your design specifications.

Designed for Critical Infrastructure
Bridge decks and pier foundations experience cyclic loading, temperature changes, and high moisture exposure. Our deformed steel bar is manufactured to respond to these challenges with high fatigue resistance for the rib pattern, consistent cross-section, and controlled chemical composition. The 25mm diameter provides the right balance of stiffness and crack resistance for moderate to heavy structural elements. Whether for highway bridges, overpasses, or deep foundation piles, this rebar helps maintain long-term serviceability and reduces lifecycle maintenance cost.
Technical Advantages at a Glance
- Consistent Rib Geometry: Precision-rolled ribs ensure uniform deformation pattern, improving bond with concrete.
- Weldability: Manufactured from select low-alloy composition that supports standard welding methods (electrodes per AWS D1.4) for field splicing.
- Bendability: Material meets cold-bend requirements without surface cracking, enabling tight radius bends for stirrups and ties.
- Corrosion Options: Standard black bar available; epoxy-coated or galvanized options are available upon request for aggressive environments.
- Custom Bundling: Bars are tied in bundles with steel straps, optionally color-coded tagged for easy grade identification.
How It Serves Your Project
For contractors, fabricators, and structural engineers, using a reliable deformed rebar means fewer site delays, predictable performance, and simpler quality inspection. Our 25mm bar offers adequate cross-sectional area for directing high moments and acts efficiently in tension zones of continuous bridge decks. It allows better spacing control, reduces the total steel tonnage in some designs, and reduces the chance of thermal cracking at an early age when innovative mix designs are used.
Shipping & Packaging
All bars are packed in seaworthy bundles. Standard shipment from Qingdao port is available. We offer containerized loading or bulk-vessel options. For each bundle, we secure the bars with steel straps, and larger bundles can include waterproof paper wrapping when specified. Loading supervision is provided to ensure zero damage during sea freight.
Ordering and Customization
We accommodate custom lengths from 1m to 14m, with tolerance of +50mm / -0mm on cutting. If you require special lengths, bending shapes, or tag marking, please provide your drawings. Our production lead time normally ranges from 15 to 30 days depending on order quantity, and we serve both project-based bulk orders and distributed reseller requirements.

Frequently Asked Questions
-
Q1: What is the yield strength of this 25mm deformed bar?
A: The minimum yield strength is 420 MPa, consistent with ASTM A615 Grade 60. Actual values are shown in the mill test certificate. -
Q2: Can the length be customized?
A: Yes, we supply standard lengths of 6m, 9m, and 12m. Custom lengths are available upon request; please indicate your requirement in your inquiry. -
Q3: Do you provide epoxy-coated bars?
A: Yes, epoxy coating is available as an option. Standard production is black bar with ribs. Coating type and thickness can be discussed based on your project specification. -
Q4: Is this bar suitable for marine or coastal bridge construction?
A: The plain carbon steel bar is suitable for typical pier foundations and bridge decks. For marine environments where chloride exposure is high, epoxy-coated or galvanized rebar is recommended. We offer those options as well. -
Q5: What tests are carried out before shipment?
A: Each production lot undergoes tensile, bend, and dimensional tests. We also provide a mill test certificate to ASTM A615 standard. Third-party inspection is welcomed. -
Q6: How is the packing arranged for sea transport?
A: Bars are tied into bundles with steel straps. Each bundle weighs approximately 2 to 3 tons. Bundles can be covered with waterproof paper at buyer’s request. Containers are loaded with careful blocking to prevent movement. -
Q7: What is your minimum order quantity (MOQ)?
A: For standard 25mm bars, MOQ is typically 25 tons. Smaller trial orders may be accepted depending on stock availability. -
Q8: Can I get a sample?
A: We can send samples of 300mm length for quality assessment if you are a verified buyer. Sample cost and freight are negotiable and can be refunded on bulk order.
