A concrete curb extruder, also known as an extruded curb machine, is a construction machine that continuously extrudes wet concrete into curb, gutter, or barrier shapes. It replaces the traditional method of using wooden or metal forms. The machine carries a hopper of wet concrete, feeds it into a shaped mold at the rear, and uses high-frequency vibration to compact the concrete into a dense, strong, and smooth finish.
The YG series uses high-frequency vibrators and attached vibration motors to ensure the concrete is properly consolidated. This results in a high-quality finish that requires no additional forming or finishing.
The machine is widely used in road construction, highway projects, parking lot construction, and landscaping. It can build curbs, gutters, sidewalks, median barriers, and other concrete structures.

How Does An Extruded Curb Machine Work?
Step 1 – Load concrete. Wet concrete is loaded into the hopper (1 m³ capacity) on top of the machine. The concrete is fed into the mold at the rear by a screw or conveyor system.
Step 2 – Extrude and vibrate. The machine moves forward (at 1‑10 m/min). The concrete passes through a shaped mold at the rear of the machine. High‑frequency vibrators compact the concrete, removing air voids and creating a dense, smooth surface.
Step 3 – Steer automatically. The automatic steering system keeps the machine in the correct alignment. The driver sets the direction, and the machine follows the line automatically.
Step 4 – Continuous paving. The machine moves forward continuously, extruding a uniform curb without stopping. No forms are needed. The curb is ready to cure immediately.
The whole process is continuous and efficient. One machine can pave hundreds of meters per hour without the labor and material costs of traditional formwork.


Where Can You Use A Curb Paver Machine?
The YG concrete curb extruder is suitable for:
- Highway and road construction – Building medians, curbs, gutters, and drainage channels.
- Parking lot construction – Extruding curbs and barriers around parking areas.
- Landscaping – Creating decorative curbs, garden borders, and pathways.
- Airport runways and taxiways – Building edge curbs and drainage systems.
- Industrial yards – Extruding curbs for truck loading areas and storage yards.
- Bridge and tunnel approaches – Building barriers and curbs on bridge decks.


Key Advantages Of A Concrete Curb Extruder
1. Fast. Paving speeds up to 10 m/min – that is 600 meters per hour. Traditional formwork methods take 10‑20 times longer.
2. No forms needed. Eliminates the cost, labor, and time of setting up and removing wooden or metal forms.
3. Consistent quality. The machine produces uniform curbs with consistent shape, thickness, and finish – every time.
4. Versatile. Can be used on roads, highways, parking lots, and landscaping projects.
5. Strong and durable. High-frequency vibration compacts the concrete, resulting in a dense, strong, and wear‑resistant finish.
6. Adjustable. The machine can be adjusted to produce different curb sizes and shapes.
Wheel Type vs Crawler Type – Which Should You Choose?
| Feature | Wheel Type (YG-20) | Crawler Type (YG-30) |
| Mobility | Faster on paved surfaces | Better on rough or soft terrain |
| Stability | Good | Excellent (tracks spread weight) |
| Best for | Road work, parking lots, paved sites | Offroad, construction sites, soft ground |
| Max curb height | 600mm | 1100mm |
| Weight | 6000kg | 7000kg |
Choose the wheel type if you are working on existing paved roads or parking lots. Choose a crawler type if you are working on unpaved, soft, or uneven ground.


Conclusion – Pave Curbs Faster With YG
A concrete curb extruder is the most efficient way to build curbs, gutters, and barriers. YG offers two models: YG-20 (wheel type, up to 600mm height) and YG-30 (crawler type, up to 1100mm height). Both use automatic steering, high-frequency vibration, and powerful 65kW engines. Paving speeds reach up to 10 m/min – that is 600 meters per hour. No forms needed. No waiting. Just continuous, high-quality curbs.
YG Machinery also offers other concrete paving equipment. Contact YG with your project requirements, curb height, and terrain type. They will recommend the right concrete curb extruder and provide a quote. Start extruding – not forming.
