You’ve got curbs to pour. Kilometers of them. Roads, parking lots, roundabouts, drainage channels. Traditional forming means wooden forms, manual pouring, labor crews, and slow progress. An extruded curb machine changes that. It extrudes concrete continuously, shaping curbs in a single pass—no forms, no waiting.
Two models: wheeled portable or crawler portable. Different curb height capacities. Different speeds. Which one fits your job? This article gives you the decision logic upfront. No fluff. Just practical answers based on your project scale and mobility needs.
What Is an Extruded Curb Machine?
Think of it as a mobile concrete extruder. It travels along the job site, receiving concrete mix through a hopper, and pushing it through a mold that shapes the curb profile. High-frequency vibration compacts the concrete as it exits, creating a dense, durable curb.
The machine moves continuously, so curbs are formed without joints or interruptions. One operator controls steering, speed, and hopper feed. No forms. No manual finishing. Just continuous curb production.
What makes an extruded curb machine different from a slipform paver? Same principle, smaller scale. A curb machine is dedicated to curbs, gutters, and small barriers. It’s narrower, lighter, and more maneuverable.
Where do people use a curb paving machine?
- Roadways and highways—edge curbs and gutters
- Parking lots—island curbs, perimeter barriers
- Roundabouts and traffic calming features
- Drainage channels and swales
- Landscape borders
- Airport pavements
- Industrial yard curbing
The machine produces curbs in various shapes—standard curb, curb and gutter, barrier, or custom profiles. The mold determines the shape.
A kerb paver machine is the same equipment—kerb is the British spelling of curb. Both terms describe a machine that extrudes concrete curb profiles continuously.

Choose YG-20 if: Your curbs are under 600mm height. You’re working on paved surfaces. You need to tow between job sites frequently. You want lower weight and lower cost.
Choose YG-30 if: Your curbs exceed 600mm—up to 1100mm. You’re working on unpaved or rough terrain. You need faster paving speed. You’re pouring barriers or tall curbs.
Typical Applications by Project Type: Extruded Curb Machine
Roadway Curb and Gutter
Typical curb height: 150–300mm
Machine choice: YG-20 works. YG-30 also works but is heavier than needed.
Profile: Curb with integrated gutter pan for drainage.
Parking Lot Islands and Perimeter Curbs
- Typical curb height: 150–200mm
- Machine choice: YG-20. Wheeled machine maneuvers well in paved lots.
- Profile: Standard curb or mountable curb.
Highway Barriers and Median Curbs
- Typical curb height: 600–900mm
- Machine choice: YG-30 required.
- Profile: Tall barrier curb, often with crash-tested profile.
Roundabouts and Traffic Circles
- Typical curb height: 150–300mm
- Machine choice: YG-20. Both machines have a 6800 mm minimum radius, sufficient for most roundabout geometry.
- Profile: Curved curb profile matching radius.
Drainage Channels and Swales
- Typical curb height: 300–600mm
- Machine choice: YG-20 or YG-30 depending on height.
- Profile: V-shaped or trapezoidal channel.
Landscape Borders
- Typical curb height: 100–200mm
- Machine choice: YG-20.
- Profile: Decorative curved top, exposed aggregate finish.
Curb Paving Machine Accessories and Ancillary Equipment
Beyond the machine itself, consider these items for a complete setup.
Molds — The profile shape determines the curb cross-section. Standard molds available: curb only, curb and gutter, barrier, mountable curb, and drainage channel. Custom molds available on request.
Stringline and sensors — The automatic steering system follows a stringline or sensor reference. Stringline kits and sensor alignment equipment are essential for accurate placement.
Concrete delivery — The machine requires continuous concrete supply. Options: concrete mixer truck feeding directly into the hopper, or a batch plant with conveyor feeding the hopper.
Power supply — Check your local voltage. The engine is diesel, but the hydraulic and electrical systems may have voltage requirements. Confirm compatibility.
Transport equipment — The machine is towable or truck-mounted. Check width and height for road transport.

Final Takeaway
An extruded curb machine is a productivity tool. It replaces formwork crews with a single-pass continuous process. Choose the wrong height capacity and your curbs won’t meet spec. Choose the wrong mobility type, and you struggle on rough terrain. Choose the wrong speed and production lags.
The right curb paving machine matches your curb height requirement, your site terrain, and your production speed target.
We build exactly that. No mismatched specs. Just solid equipment from a supplier who supports you after delivery.
Need the right extruded curb machine for your project?
Tell us:
- Your required curb height and width
- Your site terrain (paved or unpaved)
- Your production speed target
- Whether you need a specific profile or mold
We’ll recommend the right model—no upsell, just the correct fit.
