Fiberglass reinforcing bars
Corrosion-resistant fiberglass reinforcing bars for maintenance-free reinforcement with a long service life. Our corrosion-resistant fiberglass reinforcing bars have a very long functional lifespan, making them a cost-effective alternative to wood, concrete, and steel. They require minimal maintenance, even in corrosive and aggressive environments.
Fiberglass reinforcing bars (GRP) are a corrosion-free alternative to traditional steel reinforcement and are particularly well suited for constructions in aggressive environments, such as exposure to salt, moisture, or chemicals.Unlike steel, GRP does not deteriorate from corrosion, which extends the lifespan of building components and minimizes the need for repairs. The material is also lightweight, easy to work with without special tools, and requires virtually no maintenance.Common applications for GRP reinforcing bars include coastal constructions, bridges, wastewater facilities, and various industrial environments.
