Advantages of fiberglass



Fiber Dowels BrochureOrder directly

Environment friendly

The production of fiberglass dowels and fiber glass rebars produces less CO2 in comparison to the iron version. This has a positive effect on the environment.

Higher breakingpoint

We have tested the fiberglass dowel's breakingpoint and the results came out higher than the traditional steel dowel.

High tensile strength

The tensile strength of the glass fibredowel is higher compared to iron:
glass fibre dowel: 600 - 1600 n/mm2 compared to
steel dowel: 200-550 n/mm2

Resistant to chemicals

Chloride and phosphates do not affect the fiberglass rebars or dowels. 

Looking for light rebars? Fiber Dowels

No loss of strength

The fiberglass dowel or fiberglass rebars does not lose strength at low temperatures. The iron dowel or coupling rod at high temperatures do differ.

Radio Transparent

The material does not conduct radio waves, making the fiberglass dowels easier to use in sensitive environments.

Higher flexural strength

The fiberglass dowels have a flexural strength than steel dowels.

Installing dowels faster? Use fiberglass dowels

Diameter tolerance

A fiberglass dowel is always +/- 0.3 mm accurate in terms of curvature compared to steel which is close to +/- 0.5 mm.

Thermal conductivity

The thermal conductivity of the composite is 100 times lower than steel. 


The material is diamagnetic and therefore has a repulsive force.
