Introducing GFRP Mesh
In modern construction, GFRP mesh (Glass Fiber Reinforced Polymer mesh) represents an innovative and versatile solution. Its combination of corrosion resistance, lightweight design, and robust strength not only improves concrete quality but also streamlines construction processes, reduces maintenance costs, and extends the lifespan of buildings.
Reinforcement of concrete structures and mixed reinforced concrete structures
Structures located in coastal areas, airports, hospitals, military bases and more
Special purpose objects (power plants)
Weight sensitive structures
Road industry (construction of bridges, roads, tunnels)
Construção de estruturas agrícolas
Heat/cold sensitive environments (basements, patio decks)
Civil projects (commercial & residential buildings, high rises)
Benefits of GFRP mesh
- Resistência à corrosão. GFRP mesh will not rust, even in the harshest environments. Unlike steel mesh, FRP mesh ensures a longer lifespan and minimizes maintenance needs.
- Altamente resistente a produtos químicos. GFRP mesh resistant to salt ions, acids, chemicals, and the inherent alkalinity of concrete. This is important when you build concrete structures in coastal areas near seas, oceans, lakes and rivers.
- Leve. GFRP rebar is 9 times lighter in weight than the equivalent strength of Steel rebar.
- Strength. Fiberglass rebar has 3 times stronger tensile strength than steel. GFRP has substantially greater bond strength to concrete than steel which makes GFRP-reinforced concrete more resistant to cracking.

Advantages of using GFRP mesh
- Reduction of rebar scrap
- Easily cut and machined
- Easy and Rapid Installation time
- Lower transportation & storage costs
- Reduced whole-life project costs
GFRP mesh represents an evolution of steel mesh rebar and makes the GFRP composite tecnologia applicable in construction in practically every of its construction. Composite reinforcement mesh is sustainable and shows prevailing results. The use of FRP mesh in various construction projects not only enhances structural integrity but also opens new possibilities for innovative design and more efficient construction practices.
