An FRP rebar machine is a complete system used to manufacture fiberglass reinforced polymer (FRP) rebars. These composite rods are used in concrete reinforcement, offering excellent strength, corrosion resistance, and low weight.
The machine line integrates continuous processing technologies, typically including:
Fiber feeding system (usually E-glass roving)
Resin mixing and impregnation system
Preforming unit
Pulling and curing unit (usually via thermal or UV curing)
Surface shaping (including sand coating or rib patterning)
Cutting and stacking system
Fiber Feeding & Alignment
Multiple spools of fiberglass roving are drawn through tensioners and aligned into a consistent profile.
Resin Impregnation
Rovings pass through a resin bath containing epoxy or vinyl ester resin mixed with curing agents and fillers. This stage ensures complete wet-out of the fibers.
Preforming Die
The soaked fibers are formed into a round bar shape, preparing them for final dimensioning and curing.
Curing Oven or UV Chamber
The continuous rod passes through a heating oven (typically 100–150°C) or UV curing chamber to initiate hardening.
Surface Treatment (Optional)
Before final cutting, ribs or helical threads can be embossed mechanically, or sand can be coated onto the surface for better bonding with concrete.
Cutting & Final Packaging
The finished rod is cut to standard lengths (e.g., 6m, 12m) or custom sizes using an automatic cutter, then packaged for shipment.
| Section | Description |
|---|---|
| Resin Tank | With heating and mixing function |
| Fiber Feeding Rack | 20–40 bobbins, tension-controlled |
| Impregnation Unit | Stainless-steel resin bath with guide rollers |
| Heating Chamber | Electric or IR heating for thermal curing |
| Pulling System | Caterpillar-type or hydraulic pullers |
| Surface Patterning | Sanding system or rib-forming mold |
| Auto Cutter | Adjustable for fixed-length cutting |
A single production line can output:
4–6mm bars: up to 500–600 meters/hour
8–12mm bars: around 200–400 meters/hour
Larger diameters (16mm+) reduce output speed
Power consumption varies from 25kW to 45kW, depending on heating method and automation level.
| Item | Estimated Cost (USD) |
|---|---|
| Basic FRP Rebar Line | $35,000–$55,000 |
| Semi-Automatic Advanced Line | $60,000–$85,000 |
| Full Automation Line | $100,000+ |
Return on Investment (ROI):
With proper operation, a medium-speed line producing ~500kg/day can recover investment in 6–12 months, especially in high-demand markets (e.g., Middle East, Southeast Asia).
Rising Global Demand: GFRP rebars are increasingly replacing steel rebars in coastal, marine, and chemical environments.
Eco-Friendly Trend: Many regions are adopting low-carbon construction materials, including non-corrosive rebars.
Flexible Customization: You can easily adjust diameter, color, length, or rib shape depending on market needs.
A well-designed FRP rebar machine line offers an efficient, scalable, and eco-friendly way to enter the growing composite rebar industry. Whether you're a construction material supplier or a new composite investor, setting up a fiberglass rebar production line opens the door to high-margin, low-maintenance manufacturing with long-term market potential.
