Fibreglass Dowel Bars

BlackBar™  GFRP Dowel Bars are used as a load transfer device between joints in concrete slabs. They provide a mechanical connection between slabs but allow for horizontal contraction and expansion of the slab itself. This results in lower deflections at the joints and reduced slab stresses. Joint failure is often the result of corrosion of the steel dowel bar.

Black Bar Fibreglass Dowels will not rust or corrode, meet shear capacity requirements and may reduce fatigue stresses in the surrounding concrete, due to the lower stiffness of the GFRP Dowels. These bars are also electromagnetically transparent and are frequently used in high-speed toll collection areas near inductance sensors.

Beyond Materials Group PTY LTD is a growing manufacturer of  GFRP products and can meet your specification and quality requirements. From our head office in Yatala, Queensland we are able to ship our Fibreglass products Australia wide.

-2 times stronger than steel
-5 times lighter than steel
-Fibreglass rebar is naturally resistant to alkali, rust and acids.
-Moisture penetration from concrete does not spall.


-Fibreglass rebar has the same thermal coefficient expansion as concrete.
-Smaller rods allow for more critical spacing and designs.
-Fibreglass rebar is easily cut to length with regular tools.
-Fibreglass rebar does not conduct electricity or induce fields when exposed to RF energy, great for MRI or data buildings.
