FRP reinforcement has a maximum tensile strength, twice that of steel bars (BST500C) with an equal base diameter.
LIGHTER
The density of FRP reinforcement is 1.9 t / m3, it results that FRP reinforcement is 8 times lighter keeping the diameters, and 10 times lighter reducing the diameters and maintaining the physical and mechanical resistance.
MORE PROFITABLE
-lower purchase price compared to stainless steel;
-lower transport costs;
-lower costs for handling and positioning in formwork;
-longer life, at least equal to concrete, being non-corrosive.
CORROSION AND DEGRADATION RESISTANCE
FRP reinforcement is absolutely corrosion resistant and does not lead to concrete damage, unlike steel metal bars. Moreover, FRP reinforcement hardly changes its mechanical properties in aggressive environments caused by alkalis, acids and salt.
LOW TEMPERATURE RESISTANCE
FRP reinforcement can be used in any temperature range from -70°C to + 100°C without changes in its mechanical, technical and behavioral properties.
LOW THERMAL CONDUCTIVITY
The thermal conductivity of FRP reinforcement is 100 times lower than steel bars. FRP reinforcement practically does not conduct heat. As a result, FRP reinforcement cannot serve as a thermal bypass and significantly reduces heat loss.
COEFFICIENT OF THERMAL EXPANSION
The coefficient of thermal expansion of the FRP reinforcement is equal to the concrete, which eliminates the reinforcement ruptures and the formation of cracks in the concrete layer with accentuated temperature variations.
NON-CONDUCTIVE, RADIO-TRANSPARENT AND MAGNETO-INERT
FRP armature does not conduct electricity and does not accumulate static energy. It does not affect radio waves. No changes in the mechanical strength properties of the FRP reinforcement due to the effect of the electromagnetic field.
LONG AND ECOLOGICAL LIFE
FRP reinforcement doubles the durability of the structure compared to steel bars, especially in aggressive environments. No repair work required (does not raise costs). Estimated service life at least equal to that of concrete, raising it from 50 years (steel) to approx. 100 years.
