What is Basalt Fiber Reinforced Polymer Rebar?

Basalt rebar is used in industrial and civil engineering to construct residential, public and industrial buildings, and also in structural repair, and infrastructure construction.

Unlike metal rebar, and due to the resistance to corrosion, hydrochloric acid, alkali and potash media, Basalt Fiber Reinforced Polymer Rebar (BFRP) is suitable for structural units exposed to aggressive environments. Basalt plastic reinforced structures gain high strength properties and are highly durable, which help to reduce or eliminate costly repairs.

Using BFRP rebar of smaller diameters compared to metal rebar (equal in strength ratio), and reducing the transportation and installation costs (9 times lighter than stainless steel), it is possible to achieve saving up to 20%. In addition, BFRP rebar can be used in construction on a year-round basis (including a winter season).


  • Complies with GOST 31938
  • Diameter – from 4 to 36 mm
  • Length of a rod – up to 12 m (Ø to 12 mm – in coils of 50-100m)
  • Density – 2 g / cm3
  • Tensile strength – 1400 MPa
  • Dielectric
  • Non-conductor
  • Non-magnetized

Benefits of BFRP rebar

High strength

Light weight

Corrosion resistance

Non-thermal conductivity

Economic effect

The economic benefits from the use of composite rebar include saving on the rebar cost due to replacement of a larger rod diameter to equal in strength smaller one. Due to the high tensile strength (at elongation and breaking), which is higher than that of the metal rebar, it is possible to replace metal rebar with equal in strength basalt composite rebar of the smaller diameter. The table below presents equal in strength replacement of rebar diameters

Fields of application

Basalt is our competitive advantage Order right now!


Continuous basalt fiber is made by melting igneous basalt rock. It is an environmentally friendly material because no chemical additives are used to manufacture basalt fiber. It has high strength, resistance to aggressive environments, temperature stability, low electrical conductivity, and hygroscopic properties.

Savings in the construction process occurs when diameters are replaced with smaller ones according to the strength properties (tensile strength of basalt composites is higher than that of metal), lower cost of transportation and unloading, as well as optimization of assembling due to the light weight. In addition, basalt rebar does not corrode or conduct heat, it has hygroscopic properties and therefore basalt rebar reinforced concrete structures are more durable.

Basalt fiber as a reinforcing material is perfectly suited for road construction and repair, namely reinforcement of asphalt concrete and strengthening the road beds with basalt fiber and basalt grid, providing strength and durability for the roadway.
