The Ultimate Guide to Basalt Fiber Rebar: Benefits, Applications, and Price Insights

What Is Basalt Fiber Rebar?

Basalt fiber rebar is a high-performance reinforcement material made by melting natural basalt rock and extruding it into continuous fibers, which are then combined with resin to form rods. As a type of basalt FRP rebar (Fiber Reinforced Polymer), it provides a corrosion-resistant and lightweight alternative to traditional steel reinforcement, ideal for long-term durability in aggressive environments.

This material is particularly valued for its non-conductive, non-corrosive, and high tensile strength properties, making it suitable for applications where conventional steel rebar would degrade over time.

Basalt vs. Glass vs. Carbon FRP Rebar

Compared to other composite reinforcement materials:

• Basalt composite rebar offers higher temperature resistance than glass fiber rebar, while maintaining similar affordability.

• Carbon fiber rebar outperforms both in strength and stiffness, but its high cost limits usage to niche, high-performance applications.

• Basalt sits in the middle: more durable than glass, more affordable than carbon.

Key Applications of Basalt FRP Rebar

Basalt fiber rebar is primarily used in the following construction sectors:

• Concrete Structures: Ideal for bridge decks, foundations, and precast elements where corrosion is a major concern.

• Marine and Coastal Infrastructure: Its saltwater resistance makes it suitable for ports, seawalls, and docks.

• Tunneling and Mining: Basalt rebar does not interfere with electromagnetic signals, useful in sensitive underground installations.

• Roads and Pavements: Reinforcement in concrete pavements subjected to chloride-rich environments.

Cost & Procurement Advice

Basalt fiber rebar price varies depending on diameter, length, coating type, and purchase volume. As of 2025, the average price per ton ranges from $1,400 to $1,900, depending on regional availability and resin quality (epoxy or vinyl ester).

For bulk orders, especially over 10 tons, significant discounts are typically available from Chinese manufacturers. Here are a few tips for buyers:

• Request standard sizes (e.g., 10mm, 12mm, 16mm) to lower unit costs.

• Inquire whether prices are FOB or CIF, especially for overseas procurement.

• Confirm resin type used—vinyl ester resins offer better chemical resistance and durability in alkaline environments.

• Check if the supplier provides relevant certifications such as ISO or ASTM GFRP compliance.
