Product Overview

Our Carbon Steel Rebar (Hot Rolled Deformed Steel Bar) is a high-strength reinforcing steel product widely used in modern construction and civil engineering projects. Manufactured through a controlled hot rolling process, the steel bar features a ribbed (deformed) surface that significantly improves bonding strength with concrete, ensuring enhanced structural stability and load-bearing performance.

This product is designed for demanding infrastructure applications such as buildings, bridges, highways, tunnels, and foundations. With excellent tensile strength, ductility, and durability, hot rolled deformed steel bars are a reliable and cost-effective reinforcement solution for both small-scale construction and large engineering projects.

Available in multiple grades, diameters, and lengths, our carbon steel rebar meets international standards and is trusted by global contractors, engineers, and distributors.

Frequently Asked Questions (FAQ)

Q:What is carbon steel rebar used for?

A: Carbon steel rebar is used to reinforce concrete structures, improving tensile strength and preventing cracking in buildings, bridges, roads, and foundations.

Q: What is the difference between HRB400 and HRB500?

A: HRB500 has higher yield strength than HRB400, making it suitable for heavier load-bearing structures and high-rise construction projects.

Q: Can carbon steel rebar be used in outdoor environments?

A: Yes, but for highly corrosive environments, galvanized or epoxy-coated rebar is recommended for better durability.

Q: What sizes are available?

A: Standard diameters range from 6mm to 50mm, with custom sizes and lengths available upon request.

Q: Do you provide mill test certificates?

A: Yes, we provide full MTC (Mill Test Certificates) including chemical composition and mechanical test results for each batch.

Q: Can you supply customized standards?

A: Yes, we can produce rebar according to ASTM, BS, EN, JIS, or GB standards based on customer requirements.

Q: What is the delivery time?

A: Stock orders typically ship within 7–10 days, while customized orders take 15–25 days depending on specifications and quantity.
