GFRP REBAR

For a better environment of our world

01.

What is GFRP?

GFRP Rebar, or Glass Fiber Reinforced Polymer, is a fiberglass reinforcement material, also known as “fiberglass rebar.” It serves as a replacement for steel rebar to address the issue of steel rebar rusting in reinforced concrete, which leads to structural integrity loss. The fiberglass reinforcement material (GFRP Rebar) is made from fiberglass strands processed similarly to making ropes, then mixed with resin, making it strong and lightweight.

Why GFRP Rebar?

The initiative to develop, produce, and distribute GFRP Rebar in Thailand stemmed from recognizing the various issues arising from using steel as a primary material in many products. The main factor that the company aims to address is the “environmental problem.”
Currently, the production and use of steel in Thailand have expanded by about 40% each quarter, contributing to approximately 1.5% of the world’s greenhouse gas emissions. Various studies have indicated that from the beginning of production to the delivery stage, GFRP Rebar emits around 40% less greenhouse gas compared to steel rebar. Moreover, the other advantages of GFRP can help elevate Thailand’s construction industry sustainably.

Production and Forming Process

The production and forming process of GFRP rebar requires advanced technology and expertise to produce high-quality materials:
Polymer Injection Molding: Glass fibers coated with polymer are formed into GFRP rebar through a precise polymer injection molding process.
Drying and Curing: After forming, the GFRP rebar is dried and cured under controlled conditions to ensure the material is strong and durable.

04.

Quality Inspection

After production, GFRP rebar must undergo thorough quality inspection to ensure the material is strong and durable:
Strength Testing: The strength of the GFRP rebar is tested using precise instruments.
Corrosion Resistance Testing: The corrosion resistance of the GFRP rebar is tested by exposing it to chemicals and harsh environments.
