Wholesale High Strength Basalt Rebar for Underground Construction Pricelist, Suppliers

Basalt fiber is a new type of composite material combined with resin, filler, curing agent and other matrix, and formed by pultrusion process.

Product Description

Basalt Rebar Main
Product Features
High Tensile Strength: More than 3 times the strength of ordinary steel bars.
Excellent Corrosion Resistance: Unmatched durability against chemical agents.
Lightweight: Density is less than 2.0g/cm³, about 1/4 the weight of steel.
Thermal Compatibility: Expansion coefficient similar to concrete, reducing temperature stress.
Non-Conductive & Non-Magnetic: Good wave-transmitting performance and no shielding.
Eco-Friendly: Saves 5.24tce of standard coal carbon emissions per ton.

Basalt Structural Rods and Fibers naturally assimilate into concrete or cement-based products, readily replacing traditional reinforcement while improving the final structural integrity.

Product Application

Basalt Fiber Reinforced Polymer Rebar (BFRP) is non-magnetic, electrically insulated, and extremely resistant to chemical corrosion. It is widely used in specialized construction departments such as medical infrastructure (MRI rooms), airports, military facilities, and anti-radar buildings.

  • 1. Civil Engineering: Used in earthquake observation stations, seaport pier protection, metro stations, bridges, and prestressed concrete highways.
  • 2. Chemical Industry: Ideal for anti-corrosion chemical plants and storage tanks due to high resistance to acid, alkali, and salts.
  • 3. Underground Engineering: Enhances structural strength in tunnels and underground parking lots without interfering with electrical or communication systems.

Frequently Asked Questions
Q1: What are the main advantages of Basalt Fiber Rebar (BFRP) over steel?
BFRP offers 3 times the tensile strength of steel, is 1/4 the weight, and is completely immune to corrosion from acids, alkalis, and salts.
Q2: Is Basalt Rebar suitable for magnetic sensitive areas?
Yes, BFRP is non-magnetic and electrically insulated, making it perfect for MRI rooms, radar stations, and electronic equipment environments.
Q3: How does BFRP perform in concrete structures regarding temperature?
It has a thermal expansion coefficient very similar to cement concrete, which prevents internal stress and cracking caused by temperature fluctuations.
Q4: Is the installation of Basalt Rebar difficult?
Because it is significantly lighter than steel, it reduces labor intensity and transportation costs, making handling and installation much easier.
Q5: Is Basalt Rebar an environmentally friendly material?
Yes, it is a sustainable material. Each ton of basalt fiber composite bars can save 5.24tce of standard coal carbon emissions compared to traditional materials.
Q6: Can Basalt Rebar be used in marine environments?
Absolutely. Its superior corrosion resistance makes it an ideal choice for seaport piers, sea walls, and any infrastructure exposed to saltwater.
