In recent years, European and American infrastructure projects have faced increasing challenges related to thermal expansion, corrosion, and the need for durable construction materials in diverse geological conditions. SupAnchor®, a leader in geotechnical reinforcement systems, has introduced its SupFRP® GFRP Dowel Bar to address these issues, providing a reliable solution for load transfer in concrete slabs. This product is designed to offer superior performance in jointed rigid pavements, embankments, and other critical applications, ensuring structural stability and longevity.
The SupFRP® GFRP Dowel Bar is manufactured from premium raw materials, allowing customization to meet specific project requirements. It functions as a mechanical link between adjacent concrete slabs, facilitating horizontal movements to accommodate thermal fluctuations while maintaining load transfer efficiency. Key advantages include a service life exceeding 100 years, rust-free properties, high strength, non-conductivity, and non-magnetic characteristics, making it ideal for environments with electromagnetic sensitivities. These features solve engineering challenges by reducing maintenance costs, enhancing safety, and improving overall structural integrity in infrastructure projects.
To illustrate the technical specifications, the following table provides detailed data for various models, showcasing the adaptability of SupAnchor's dowel bars in different engineering scenarios. This data underscores how the product's parameters, such as transverse shear load and diameter, align with the demands of modern construction, including those addressed by self drilling anchor systems in geotechnical reinforcement.

|---|---|---|---|---|---|
| DB16 | 16 | 35 | 200 | 9-11 | 0.43 |
| DB20 | 20 | 55 | 310 | 9-11 | 0.67 |
| DB25 | 25 | 85 | 490 | 9-11 | 1.05 |
| DB32 | 32 | 130 | 800 | 9-11 | 1.71 |
| DB38 | 38 | 180 | 1130 | 9-11 | 2.41 |
| DB45 | 45 | 255 | 1590 | 9-11 | 3.37 |
The SupAnchor® GFRP Dowel Bar is extensively used in jointed rigid pavement, construction joints, embankments, and mechanically stabilized earth (MSE) walls. Its non-conductive and non-magnetic properties make it particularly valuable in work areas with electromagnetic sensitivities, such as near power lines or in medical facilities. By enabling efficient load transfer and accommodating thermal movements, this product supports the development of resilient infrastructure across Europe and America, from highways to urban projects. In contexts where self drilling anchor bolts and hollow bar anchors are employed for geotechnical reinforcement, the dowel bar complements these systems by ensuring joint stability in concrete structures.
The adoption of SupAnchor's GFRP Dowel Bar contributes significantly to global infrastructure, tunneling, mining, and geotechnical safety initiatives. Its long service life and corrosion resistance reduce environmental impact and maintenance demands, aligning with sustainable construction practices. As part of a broader geotechnical reinforcement system, including drill-and-grout bolts and soil nail systems, this product enhances the reliability of critical projects. SupAnchor's innovation in this area addresses the growing need for durable materials in aging infrastructure, supporting economic growth and public safety in regions with varying climatic and geological challenges.
