GFRP Technical Characteristics

ADVANTAGES OF GFRP REBARS

Discover the numerous benefits of GFRP rebars, including corrosion resistance, lightweight properties, high strength, and long-term durability, that make them an excellent alternative to traditional steel rebars.

High Strength to Weight Ratio

Despite their light weight, GFRP rebars provide a high tensile strength, making them strong and efficient.

Corrosion Resistance

GFRP rebars do not corrode, making them ideal for use in environments exposed to moisture and chemicals.

Lightweight

GFRP rebars are significantly lighter than steel, reducing transportation and handling costs.

Cost Efficiency

For the same weight, GFRP rebars are 4 times the amount compared to steel rebars, offering significant cost savings.

Non-conductive

GFRP rebars do not conduct electricity, making them ideal for use in electrical and magnetic sensitive environments.

Thermal Insulation

GFRP rebars provide better thermal insulation, reducing the risk of thermal bridging.

Ease of Installation

The lightweight nature of GFRP rebars makes installation faster and less labor-intensive.

Long Term Durability

GFRP rebars maintain their structural integrity over time, reducing maintenance costs and enhancing the longevity of constructions.

Mechanical Properties

Design of GFRP Member

The stress-strain diagram of GFRP is linear.

Stress distribution is approximated with a rectangular equivalent stress block used for cross-section analysis of a reinforced concrete.
