Fiberglass Roving Glass Fiber Yarn for Cement Concrete

Glass Fiber Yarn is a high-performance glass fiber yarn engineered from ultra-fine glass filaments, delivering exceptional tensile strength and chemical corrosion resistance. Specifically developed for spray application processes, this yarn is treated with a proprietary silane-based sizing agent that ensures superior compatibility with unsaturated polyester resins. Its unique composition and processing make it an ideal reinforcement material for thin-section concrete applications, where strength, durability, and aesthetic precision are critical.

Glass Fiber Yarn Key Applications

1.Concrete Reinforcement:

   1.1 Architectural precast panels, decorative concrete elements, and custom 

          countertops.

    1.2 Structural components requiring lightweight reinforcement without 

           compromising load-bearing capacity.

2. Industrial & Composite Industries:

    2.1  Automotive components (e.g., body panels, structural reinforcements).

    2.2 Marine applications: FRP (fiberglass-reinforced polymer) boat hulls,  

            offshore structures, and corrosion-resistant pipelines.

     2.3 Infrastructure: Storage tanks, cooling towers, sanitary fixtures, and chemical-resistant ductwork.

Glass Fiber Yarn Technical Advantages

1.Superior Mechanical Performance:

    1.1 High tensile modulus provides optimal reinforcement for reducing cracking in concrete under flexural loads.

    1.2 Low elongation at break ensures dimensional stability in high-stress applications.

2.Chemical Durability:

     2.1 Resistant to alkalis in concrete and aggressive chemicals in industrial environments.

     2.2 Marine-grade corrosion resistance for offshore and coastal infrastructure.

3. Process Efficiency:

     3.1 Spray-friendly design enables uniform distribution and consistent fiber orientation in composite layups.

     3.2 Sizing agent enhances wet-out with resins, minimizing voids and improving composite integrity.

4.Compliance & Quality Assurance:

    4.1 Rigorously tested to meet international and national standards for reliability and traceability.

    4.2 Batch-to-batch consistency ensures reproducibility in large-scale manufacturing.

Glass Fiber Yarn Applications Beyond Concrete

While optimized for concrete reinforcement, XRT-GFY’s versatility extends to:

Aerospace: Lightweight composite components for non-structural applications.

Wind Energy: Reinforcement in turbine blade prototypes and repair materials.

Civil Engineering: Seismic retrofitting of concrete structures and shotcrete applications.
