Wholesale Basalt Rebar with 4-30mm diameter Product, Supplier

Product Introduction

Basalt rebar is a type of reinforcement bar made from basalt fibers, which are extracted from volcanic rock. It is an alternative to traditional steel reinforcement used in construction projects. Basalt rebar offers several advantages over steel rebar, including higher tensile strength, lighter weight, and corrosion resistance. These properties make it particularly suitable for applications in harsh environments where corrosion is a concern, such as marine structures, bridges, and chemical plants.resistance of asphalt concrete.

Frequently Asked Questions

Why is basalt rebar better than steel for corrosion?

Basalt fiber composite bars possess natural chemical inertness, meaning they do not rust or corrode even when exposed to salt water, chemicals, or high humidity, unlike traditional steel.

How does the weight of basalt rebar compare to steel?

Basalt rebar is significantly lighter, with a density of less than 2.0g/cm3. This is approximately 1/4 the weight of ordinary steel bars, making transportation and installation much easier.

Can basalt rebar be used in magnetic sensitive areas?

Yes. Because it is non-conductive and provides no magnetic shielding, it is perfect for use in hospitals (MRI rooms), airports, and electronic research facilities.

Is basalt rebar environmentally friendly?

Absolutely. Each ton of basalt fiber composite bars can save 5.24tce of standard coal carbon emissions, making it a sustainable choice for green construction projects.

What is the tensile strength of basalt rebar?

Basalt rebar is incredibly strong, offering high tensile strength that is more than 3 times the strength of ordinary steel bars of the same specification.

Does basalt rebar bond well with concrete?

Yes, its thermal expansion coefficient is very similar to concrete, which ensures that there is no significant temperature stress between the two materials, maintaining structural integrity.
