GFRP rebar HARDplus is innovative alternate and substitute to steel bar
100% adhesion to concrete! HARDplus is designed for high loads!
FRP (fiber reinforced polymer) rebar with sand coating HARDplus – non-metallic rods composed of glass, basalt, carbon or aramid fibers impregnated with thermohardening or thermoplastic polymer binders. FRP rebar with glass fibers is called glass fiber reinforced polymer rebar (GFRP rebar), FRP rebar with basalt fibers is called basalt fiber reinforced polymer rebar (BFRP rebar), FRP rebar with carbon fibers is called carbon fiber reinforced polymer rebar (CFRP rebar). For excellent adhesion to concrete GFRP rebar is covered with special-purpose ribs or sand coating while its production. Our company manufactures basalt and glass fiber reinforced polymer rebar. HARDplus GFRP rebar is twice stronger than steel bars, conducts no heat, no decay and 43% more cast effective!
Due to the fact that GFRP rebar is 2-2.5 times stronger at break, GFRP rebar with a smaller diameter can substitute steel bars:
|HARDplus GFRP rebar||Steel rebar||Properties||Steel A-III||HARDplus GFRP rebar|
|4 mm||6 mm||Ultimate tensile strength||390-490 MPa||800-1300 MPa|
|6 mm||8 mm||Elongation||25%||2,2%|
|7 mm||10 mm||Modulus of elasticity||210 000 MPa||55 000 MPa|
|8 мм||12 мм||Thermal conductivity ratio||46 W/(m0 °C )||0,35 W/(m0°C)|
|10 mm||14 mm||Linear expansion ration||13-15 ах-5/°C||9-12 ах-5/°C|
|12 mm||16 mm||Density||7850 kg/m3||1900 kg/m3|
|14 mm||18 mm||Electrical conductivity||highly conductive||non-conductive|
|16 mm||20 mm||Resistance to aggressive environment||corrosible and low resistant||corrosion and acid resistant|
|GFRP rebar diameter||Total quantity in a coil/roll||Coil/roll diameter||Coil/roll weight|
|4 mm||100-200 m||0,80 m||up to 5 kg|
|6 mm||50-200 m||0,80 – 1,00 m||up to 10 kg|
|7 mm||50-200 m||1,00 – 1,20 m||up to 12 kg|
|8 mm||50-200 m||1,00 – 1,50 m||up to 15 kg|
|10 mm||50-100 m||1,25 – 1,75 m||up to 20 kg|
|12 mm||50-100 m||1,75 m||up to 25 kg|
|14 mm||6-12 m||in bars|
|16 mm||6-12 m||in bars|
In order to deliver 2 km of steel bars you will need special-purpose equipment, and in order to conduct loading and unloading you will need pretty much time and workers. More over, the cost of all these operations will be quite price.
In order to deliver 2 km of HARDplus GFRP rebar you will just need a car. Due to the fact that GFRP rebar can be delivered in coils/rolls and its weight is about 10 times lower than of steel bars, loading and unloading operations will take just about 15 minutes and 1 worker.
GFRP rebar with sand coating HARDplus
Normal GFRP rebar
Since conventional composite rebar is slidable and has 83% adhesion to concrete, its application is limited and suitable for constructions with low loads only. Composite rebar with sand coating HARDplushas no such disadvantages, which makes it twice more reliable!
