GLASS FIBER-REINFORCED POLYMER (GFRP) REINFORCEMENT IN INDUSTRIAL AND CIVIL CONSTRUCTION – LIGHTER, STRONGER, AND CHEAPER THAN STEEL
Manufacturing and supplying of GFRP rebars
OOO “Tekhnoplast” Manufacturing Company manufactures and supplies composite rebars of periodic profile (6-30 cm. and more in diameter) made of basalt or glass fibers bound with epoxy-diane resin based polymer.
GFRP rebars are manufactured in any length (may also be coiled) with ribbed surface of helical profile.

COMPARISON OF FRP REBAR WITH REINFORCING STEEL
| Characteristics | Reinforcing steel class А-Ш (А400С) ГОСТ 5781-82 | Fiber-reinforced polymer rebar (GFRP — glass-fiber plastic, BFRP — basalt-fiber plastic) |
| Material | Steel 35ГС, 25Г2С etc. | GFRP — polymer-bound glass fiber 13–16 micron in diameter; BFRP — polymer-bound basalt fiber 10–16 micron in diameter |
| Elastic Modulus, MPa | 200000 | 55000-GFRP 71000-BFRP |
| Ultimate tensile strength, MPa | 360 | 1200-GFRP 1300-BFRP |
| Stress-strain behavior (“strain vs. deformation”) | Curve line with yield strain under load | Straight line with strain linear dependence under load up to the breaking |
| Comparative extension, % | 25 | 2,2-GFRP and BFRP |

10 BENEFITS OF FRP REBAR:
- Several times cheaper
- 7 Times Lighter than metal rebars
- 3.5 Times Stronger
- Non corrosive material
- Non-conducting - dielectric
- Non heat-conducting
- Radioparent – magnet-inert
- Prolongs the service life of buildings by 3-4 times
- Highly flexible – as a result – able to withstand seismic effects
- Dozens of times more durable than metal
