Fiberglass concrete rebar & mesh

Buy fiberglass rebar

Fiberglass concrete rebar are used throughout the world – in the US, Canada, Japan and European countries – Since the 70s of the last century. In the progressive countries in the last century it became clear how much benefit can be extracted from the use of fiberglass rebar. We offer rebar with diameters from 4 to 24 millimeters.

Reinforcing fiberglass mesh


Composite (fiberglass) mesh is used for reinforcing floors, roads, airports and other areas. This is an equally strong replacement of the steel mesh. We offer a grid with a cell of 50 * 50, 100 * 100 and 150 * 150 mm. The available diameters are 2, 2.5, 3, 4 and 5 mm. Supplied in rolls and sheets.

Mesh for bricks or concrete blocks


Masonry mesh is used to reinforce masonry in the construction of houses with blocks and bricks. The diameter of the mesh is 2 mm. It is produced in rolls of different widths – 20, 25, 33 and 50 cm. If you need a mesh with different width, you can buy a roll with width 1 meter and cut it by yourself.

About us

Who we are and our advantages

Our advantages are low prices, careful selection of raw materials and strict adherence to production technology. We make delivery all over the world.

  • Image High quality rebar

A light weight

You get a fiberglass bar, which is 8 times lighter than steel, which reduces the overall weight of the structure and the load on the foundation without losing strength.

Environmentally friendly

Plastic concrete rebar - is safe for human health and does not contain harmful radionuclides. Our products have been tested, there are corresponding certificates.

Save up to 50%

You significantly reduce the estimate, even if you change metal to fiberglass diameter in diameter. And taking into account an equally strong replacement of the reinforcement, the savings amount to 50%.

Saving on shipping

You save on delivery due to its light weight and small volume. The required volume for reinforcing the slab foundation of a medium-sized house of 3000 linear meters - fits into the trunk of a car.

Energy Efficiency

You continue to save even during the management of the building, since the cost of heating the building, reinforced with fiberglass, is lower in comparison with steel reinforcement.


You build for many years! Due to the high chemical and corrosion resistance of reinforcing composite materials, the life of fiberglass reinforcement in the body of concrete is more than 100 years (in contrast to steel analogues).

Radio transparency

You use an armored frame from a dielectric that does not conduct electricity, getting an increase in radio transparency and reducing the influence of electromagnetic fields.

Low thermal conductivity

You build a building without "cold bridges", because the fiberglass reinforcement does not conduct heat, unlike steel. For countries with a cold climate, the problem of heat losses and freezing of walls, floors and foundations is especially urgent.

Easy installation

You simplify the process of cutting and mounting - with a viscous reinforcement, any worker can handle with a minimal set of tools and forces.

Fiberglass rebar vs steel rebar

Fiberglass rebar

0.63$/per meter (for example 10 mm rebar)

  • Corrosion Resistance. It resists large range of chemicals and stable when immersed in water.
  • Strength. The tensile strength depends on the diameter of the rebar. Usually, this is 1000 MPa.
  • Weight. Weights 10 times less than steel. Easy to transport.
  • Installation. You can cut the required dimensions with simple tools. No welding is required.
  • Thermal Properties. Does not conduct heat. The coefficient of thermal conductivity is 35 BTU. Thermal expansion - 5-6.
  • Cost. Low price, cheap delivery and long service life, which together reduces the cost of the project.
  • Electrical Conductivity. Does not conduct electricity.
  • EMI/RFI Transparency. Do not interfere with radio signals and wireless networks. It can be used for radars, antennas, electrical cabinets and rooms for magnetic resonance imaging.
  • Modulus of Elasticity. 6.7 X 10⁶ psi

Steel rebar

4$/per meter (for example 10 mm rebar)

  • Oxidation and corrosion are possible. Requires a protective coating in corrosive environments.
  • Tensile strength of 390 MPa.
  • You may need special equipment for lifting and a large truck for transportation.
  • It often requires welding and cutting with special tools.
  • Conducts heat. The coefficient of thermal conductivity is 12 times higher - 416 BTU. Thermal expansion - 7.
  • On a long distance will cost more than fiberglass rebar.
  • Conducts electricity
  • Can make interfere with EMI / RFI signals.
  • 29 X 10⁶ psi
