Comparing GFRP and Steel Rebar: A Clear Choice for Sustainable Construction

Feature GFRP Rebar Steel Rebar
Tensile Strength Up to 2x stronger than steel. Approximately half the tensile strength of GFRP.
Weight About 75% lighter than steel. Heavier, leading to increased transportation and handling costs.
Corrosion Resistance Non-corrosive, resistant to chloride ions and alkaline environments. Prone to corrosion, especially in moist or saline environments, requiring additional protection.
Durability and Maintenance Requires no maintenance, with a service life extending beyond 100 years. Requires regular maintenance to prevent corrosion, with a shorter service life.
Environmental Impact Non-toxic and recyclable, contributing to sustainable construction practices. Production and corrosion treatment have a higher environmental impact.
Thermal Conductivity Low thermal conductivity, reducing thermal bridges and energy loss in buildings. Higher thermal conductivity, potentially leading to inefficiencies in building insulation.
Electrical Conductivity Non-conductive, safe for use in applications sensitive to electrical interference. Conductive, posing risks in environments where electrical insulation is required.
Magnetic Transparency Transparent to magnetic fields, suitable for MRI rooms and other sensitive environments. Magnetic, not suitable for use in environments sensitive to magnetic fields.
