Service overview

About

Dextra DuraBar is a GFRP (glass fibre reinforced polymer) composite reinforcement bar designed to replace conventional steel rebar in concrete construction. Manufactured by Dextra Group in ISO-9001 and ISO-14001 certified factories, DuraBar is four times lighter than steel while delivering twice the tensile strength.

The critical advantage is permanence. Steel-reinforced concrete starts deteriorating after roughly 30 years of service in Australian conditions, with repair and replacement costs across the country running to an estimated $8 billion per year. DuraBar GFRP eliminates this problem at source: it cannot corrode, cannot conduct electricity, and has an expected design life exceeding 100 years.

Across residential driveways, pathways, pool decks, tennis courts, shed slabs, landscaping, and marine and water-exposure applications, DuraBar replaces steel mesh and reinforcing bar with a lighter, safer, longer-lasting alternative. Available as straight bars, bent bars, and pre-tied carpet mats.

Common questions

Frequently asked questions

How does DuraBar compare with conventional steel mesh?

DuraBar replaces steel mesh in most slab and pavement applications, delivering equivalent or superior structural performance with a fraction of the weight and none of the corrosion risk. Site crews can carry, cut, and place DuraBar by hand — no cranes, no two-person lifts, and no risk of leg cuts from sharp mesh edges. Engineering design needs to account for GFRP's different stiffness properties (refer to published GFRP design guides).

Is it approved for Australian construction?

What's the expected service life?

Can it be cut and bent on site?
