GFRP Rebars do not contain metal – they are the only choice when electrical neutrality is required and the most cost-effective. Tuf-Bar Fiberglass rebar contains zero metal or ferrous material which makes it both nonmagnetic and nonconductive
GFRP will not interfere with magnetic fields and is ideal for MRI machine rooms in hospitals, research facilities, toll roads high energy substations and power plants, or whatever sensitive electronic devices are used. GFRP rebar to ensure that there is no interference with delicate circuitry or equipment that generates a magnetic field or requires a very high electric current.
The use of GFRP Reinforcing bars has a significant advantage. It can reduce the amount of concrete needed by minimizing the concrete cover.
GFRP removes any induction problems caused by stray currents. Because of its electrical neutrality, GFRP eliminates all needs of grounding and the increase of concrete coverage to eliminate the passage of electrical current from steel reinforcement into concrete. GFRP is unbeatable for, train tracks and electrical underground enclosures
No longer are shielding and complex earthing systems, on-site welding required for concrete reinforcing when using Tuf Bar in place of traditional steel reinforcing.
Made using the pultrusion process, Tuf Bar rebar has a dielectric strength of 60KV/in. The dielectric strength of the material represents the necessary strength of an electrical field for the material to break down arcing. In other words, a 25mm length of bar would need 60,000 Volts potential difference in between the cathode and the anode for arcing to occur. Similar products to Tuf Bar are used as isolators by power authorities because of their very high dielectric strength.Schedule a Consultation
