Hemaokang Steel (Shandong) Co., Ltd. is pleased to present our Reinforced Steel Rebar for Bridge Deck Construction ASTM A615 Grade 40. As a trusted manufacturer with an annual export value of US$50–100 million and ISO9001 certification, we deliver high-quality rebar that meets the rigorous demands of modern bridge deck projects. Our Grade 40 rebar combines reliable tensile strength with excellent weldability and ductility, ensuring structural integrity in heavy-load environments. With a global presence spanning North America, Europe, Asia, and beyond, Hemaokang Steel is your partner for durable, cost-effective reinforcement solutions.
Product Overview
This deformed steel bar is specifically designed for bridge deck construction, where high bond strength with concrete is critical. Manufactured in strict accordance with ASTM A615 Grade 40 specifications, each batch undergoes rigorous quality control. The ribbed surface provides superior mechanical anchorage, reducing slippage and enhancing load transfer. Available in a range of diameters and customizable lengths, our rebar supports diverse engineering requirements.
Key Features & Technical Specifications
- Reliable Mechanical Properties: Yield strength of 280 MPa (40,000 psi) minimum, tensile strength of 420 MPa (60,000 psi) minimum – consistent with ASTM A615 Grade 40.
- Enhanced Bonding: Deformed surface pattern increases friction with concrete, minimizing crack propagation and improving structural durability.
- Weldability: Low carbon content ensures good weldability, allowing easy on-site fabrication and splicing.
- Bendability: Excellent ductility permits cold bending without cracking, meeting job site requirements for hooks and stirrups.
- Uniform Dimensions: Tight tolerances on diameter, length, and rib geometry ensure consistent performance across every shipment.
- Corrosion Resistance: Standard mill finish provides basic protection; optional epoxy coating or galvanization available upon request for harsh environments.

Frequently Asked Questions (FAQ)
1. What is the difference between Grade 40 and Grade 60 rebar?
Grade 40 has a minimum yield strength of 40,000 psi (280 MPa), while Grade 60 offers 60,000 psi (420 MPa). Grade 40 is often preferred for lighter structural applications or where ductility and weldability are prioritized, such as bridge decks subject to moderate loads.
2. Can this rebar be used in seismic zones?
ASTM A615 Grade 40 rebar provides adequate ductility for many seismic design requirements. However, for high-seismic regions, designers may specify Grade 60 or special seismic hooks. We recommend consulting your structural engineer for specific project needs.
3. Do you offer smaller diameter rebar for bridge deck reinforcement?
Yes, we supply diameters from 10 mm (3/8 inch) upward. Smaller diameters are commonly used for top mats and temperature reinforcement in bridge decks. Please contact us with your required sizes.
4. Is the rebar available with epoxy coating for corrosion protection?
Yes, we can provide epoxy-coated or galvanized rebar upon request. This adds extra protection in de-icing salt environments, though it increases cost. Standard mill finish is suitable for most interior applications.
5. What is the typical lead time for an order of 500 tons?
Lead time depends on the specification and order volume. For standard Grade 40 rebar, we can usually ship within 15–25 days after receiving the deposit. Custom lengths or coatings may require additional time. We provide a confirmed schedule upon order confirmation.
6. Do you provide mill test certificates and third-party inspection?
Absolutely. Each shipment comes with a mill test certificate (MTC) showing chemical and mechanical properties. We also welcome third-party inspection by SGS, Bureau Veritas, or other agencies at the buyer’s cost.
7. How do you package the rebar for export?
Rebar is bundled with steel straps, typically in 2–5 ton bundles. We can also strap bundles for easy crane handling. Waterproof wrapping or container lining is available for moisture-sensitive destinations.
8. Can I order a sample before placing a bulk order?
Yes, sample orders are welcome. We can provide a small quantity (e.g., 10 pieces) for quality verification. Please note that freight charges for samples are usually borne by the buyer.
