GFRP Dowel Bars
Seamless Load Transfer for Concrete Joints
Corrosion-resistant and electromagnetically neutral dowel bars designed to provide superior load transfer across concrete joints without the risk of spalling.
Reliable Load Transfer, Zero Rust.
Concrete joints are highly susceptible to moisture and chloride penetration, making traditional steel dowels a massive liability due to corrosion and subsequent concrete spalling. Our GFRP Dowel Bars eliminate this risk entirely. They provide excellent shear transfer across expansion and contraction joints while maintaining complete resistance to rust, ensuring the structural integrity of your pavements and slabs for decades.
Key Benefits
Discover why our GFRP solutions outperform traditional materials in every category.
Eliminates Joint Spalling
Zero rust means no expansion inside the concrete, preventing cracking and spalling at the joints.
High Shear Strength
Engineered to withstand extreme shear forces and transfer heavy traffic loads effectively.
Radio Transparent
Perfect for toll booth areas and automated vehicle sensor zones.
Easy Installation
Lightweight nature allows for faster placement and reduced labor fatigue.

Frequently Asked Questions
Find answers to the most common questions about this product.
Unlike rebars which need to bond tightly to concrete, dowel bars must allow the concrete slabs to expand and contract (slip) horizontally while transferring vertical shear loads.
Yes, they can be inserted into drilled holes and secured with appropriate epoxy resins for retrofitting or repairing existing joints.
