The new developed reinforced basalt fiber profiled rebar has a
high corrosion resistance combined with outstanding material
qualities. An additional advantage is the nearly equal thermal
expansion coefficient of Basalt Rebar and the surrounding matrix
which reduces the tension caused be temperature changes.
Advantages:




Light weight
High corrosion resistance
Low required depth of coverage
Higher tensile strength compared to steel (St37)
 Variable diameter to meet customers’ requirements
 Less need of rebar in the structure caused by better
performance of basalt-rods compared to steel
