Carbon Steel Rebar: The Backbone of Modern Construction

Carbon Steel Rebar, also known as reinforcing steel or reinforcement steel, is an indispensable material in the realm of civil engineering and construction. As a leading product from Baoli Iron Steel, our rebar is specifically engineered to significantly enhance the tensile strength and overall structural integrity of concrete, transforming a brittle material into a robust and durable composite structure.

Superior Mechanical Anchorage and Bonding

The characteristic ribbed or deformed surface of our carbon steel rebar is not merely aesthetic; it’s meticulously engineered for superior mechanical anchorage. These deformations create an exceptional bond with concrete, ensuring that tensile forces are efficiently transferred from the concrete to the steel. This synergy prevents cracking, controls crack width, and enables the reinforced concrete to perform cohesively under various stresses, including tension, compression, and shear forces.

Key Characteristics and Benefits:

• Enhanced Structural Strength: Drastically improves the tensile and shear strength of concrete structures, making them resilient to heavy loads and dynamic stresses.
• Crack Prevention: Effectively distributes internal stresses, preventing and controlling the formation and propagation of cracks, thereby extending the service life of structures.
• Ductility and Weldability: Manufactured to specific standards that ensure excellent ductility, allowing it to deform without fracturing under stress. Certain grades are also optimized for field welding.
• Versatile Applications: Suitable for a vast array of construction projects, from residential foundations to large-scale infrastructure.
• Cost-Effectiveness: A reliable and economically viable solution for concrete reinforcement, offering long-term durability and minimal maintenance.

Common Grades and Standards:

Baoli Iron Steel provides Carbon Steel Rebar conforming to various international standards, ensuring suitability for diverse project requirements and regulatory compliances. Key grades include:

• ASTM A615 (USA): Standard Specification for Deformed and Plain Carbon-Steel Bars for Concrete Reinforcement. Available in grades such as Grade 40, Grade 60 (most common), and Grade 75, offering different yield strengths.
• ASTM A706 (USA): Standard Specification for Low-Alloy Steel Deformed and Plain Bars for Concrete Reinforcement. Known for its excellent weldability due to controlled chemistry.
• BS 4449 (UK): Steel for the reinforcement of concrete – Weldable reinforcing steel – Bar, coil and decoiled product. Common grades like B500A, B500B, and B500C.
• DIN 488 (Germany): Reinforcing steels – Reinforcing steel bars; dimensions and mass; design values and testing. Common grades are B500A and B500B.
• JIS G3112 (Japan): Steel bars for concrete reinforcement. Grades such as SD295, SD345, SD390, and SD490.
• Custom Grades: We can also accommodate requests for specific local or project-specific standards.

Surface Treatments for Enhanced Performance:

While standard (black) rebar is widely used, we also offer specialized treatments for enhanced durability in aggressive environments:

• Epoxy-Coated Rebar (FBE Rebar): Provides an excellent barrier against corrosion, ideal for bridges, marine structures, and areas exposed to de-icing salts.
• Galvanized Rebar: Offers superior corrosion resistance through a zinc coating, suitable for highly corrosive environments.

Applications of Carbon Steel Rebar:

The versatility and strength of carbon steel rebar make it indispensable across almost all types of concrete construction:

• Buildings: Foundations, columns, beams, slabs, walls, shear walls.
• Infrastructure: Bridges, highways, tunnels, dams, retaining walls.
• Precast Concrete: Pipes, culverts, panels, utility poles.
• Industrial Structures: Factories, warehouses, power plants.
• Marine Structures: Piers, jetties, seawalls.
