Non-metal bars for concrete reinforcement made of composite materials with the diameter from 4 to 20 mm. The rods have spiral ribs on the whole surface. These composite bars are designed for reinforcement in concrete structures.
The use of composite bars doubles the life and service life of the structure compared to conventional steel reinforcement, especially in aggressive environments containing acids, chlorides and alkalis.
In reinforced concrete structures, reinforcement is the most important, but at the same time it is susceptible to negative external influences. Under the influence of moisture and alkaline concrete environment, steel reinforcements corrode. This leads to structural losses, shortened service life and costly and complex repairs.
