Building concrete curbs the old way is slow.Set up forms. Pour concrete. Wait for it to dry. Remove the forms. And the lines are not always straight.
A concrete curb machine changes everything. It moves forward while shaping the curb in one pass. No forms. No waiting. Just a continuous, smooth curb.
If you’re comparing different machines, start with our Curb and Gutter Machine for Sale overview.
But picking the wrong machine causes problems. Too small, and you cannot handle big projects. Too big, and you waste money on features you do not need.
Only three numbers matter when choosing a concrete curb machine: curb height, curb width, and paving speed. Get these right, and the machine works. Get them wrong, and nothing else fixes it.
Curb Height – How Tall Can Your Concrete Curb Machine Go?
Curb height is the first number to check. It tells you the maximum height of the curb the machine can form.
Most concrete curb machines offer two height ranges:
| Model | Max Curb Height | Best For |
| YG-20 | ≤600mm (about 24 inches) | Sidewalks, residential streets, parking lots |
| YG-30 | ≤1100mm (about 43 inches) | Highways, barriers, large infrastructure |
Why height matters:
A sidewalk curb is usually 150-200mm tall. A highway barrier can be 800mm or taller. If your machine only forms 600mm, it cannot handle the big jobs.
How to choose curb height:
Measure the tallest curb you normally build. If you work on residential streets and parking lots, a 600mm machine is enough. If you build highways, drainage channels, or concrete barriers, go with 1100mm.
Also consider future work. If you plan to bid on larger projects, buy the bigger machine now. Buying twice costs more.
YG-20 curb machine handles heights up to 600mm. YG-30 curb machine handles heights up toThe YG-20 Concrete Curb Machine handles heights up to 600mm. The YG-30 Concrete Edging Machine handles heights up to 1100mm.
Curb Width – How Wide Can Your Curb Be?
Curb width is the second number. It tells you the maximum width of the curb.
Both YG-20 and YG-30 handle width up to 2000mm (about 79 inches). This is wide enough for most projects.
Why width matters:
Some projects need wide curb sections. Highway medians can be 1000mm wide. Drainage channels need width for water flow. Sidewalk curbs are usually narrow.
How to choose curb width:
Standard curbs are 150-300mm wide. If you only build standard curbs, most machines work. If you build medians or wide drainage channels, check the machine’s max width.
What to watch:
The machine’s width capacity is the maximum. You can always form narrower curbs by changing the mold. But you cannot form wider than the machine’s limit.

Paving Speed – How Fast Does Your Kerb Laying Machine Lay?
Paving speed is the third number. It tells you how many meters of curb the machine lays per minute.
| Model | Paving Speed | Per Day Estimate |
| YG-20 | 1-7 m/min adjustable | 500-1000 meters |
| YG-30 | 1-10 m/min adjustable | 800-1500 meters |
Why speed matters:
Speed decides how fast you finish the job. A machine that lays 7 meters per minute covers 420 meters per hour. That is 1,000 meters in a 2.5 hour shift.
Compare that to manual work. Traditional curb building with forms takes 10-20 meters per day per crew. The concrete curb machine is 20-50 times faster.
How to choose paving speed:
If you work on small projects, the lower speed range works fine. If you work on highways or large developments, the extra speed means finishing days or weeks early.
Example:
A highway project needs 2 kilometers of curb. A 10 m/min machine finishes in about 3.5 hours of paving time. A 7 m/min machine takes about 5 hours. The difference is small for one day. Over a week, the faster machine saves a whole day.
Two Models – Which One Fits Your Project?
YG offers two main concrete curb machine models.
| Feature | YG-20 | YG-30 |
| Type | Portable wheel type | Crawler type |
| Max curb height | ≤600mm | ≤1100mm |
| Max curb width | ≤2000mm | ≤2000mm |
| Paving speed | 1-7 m/min | 1-10 m/min |
| Weight | 6000kg | 7000kg |
| Steering | Automatic | Automatic |
| Engine | 65kw diesel | 65kw diesel |
YG-20 is best for:
- Sidewalks and residential streets
- Parking lot perimeter curbs
- Small municipal projects
- Contractors who move between job sites often
- Projects where curb height is under 600mm
YG-30 is best for:
- Highways and main roads
- Large infrastructure projects
- Drainage channels and barriers
- Projects where curb height is over 600mm
- Contractors working on long, continuous paving
Slipform vs Precast – Why Slipform Wins
Before machines, contractors used precast curbs. Workers made curbs in a factory, trucked them to the site, and installed them. It worked. But it was slow.
Comparison:
| Factor | Slipform Machine | Precast Curbs |
| Installation speed | 1-10 m/min | 2-5 m/hour |
| Workers needed | 2-3 | 8-12 |
| Joints | None, continuous | Many joints |
| Strength | One solid piece | Weak at joints |
| Formwork | None | Need forms |
| Material waste | Low | Higher |
Slipform advantages:
No joints – The curb is one continuous piece, with no weak points where water gets in.
No formwork – You do not buy, set up, or remove forms. This saves time and materials.
Faster – A slipform concrete machine lays hundreds of meters per day. Precast installation takes days for the same distance.
Lower labor cost – One or two workers operate the machine. Precast needs a full crew.
Better quality – Machine-made curbs are straight and consistent. No human error.

Wheeled vs Crawler Curb Machine – Which Undercarriage Is Better?
The YG-20 uses wheels. The YG-30 uses crawler tracks.
Wheeled (YG-20):
- Easier to move between job sites
- Lower transport cost
- Works on paved roads and hard ground
- Good for small and medium projects
Crawler (YG-30):
- More stable on rough terrain
- Better grip on slopes and soft ground
- Higher weight, more stability for large jobs
- Good for highways and large infrastructure
How to choose:
If you move between many small job sites, choose wheeled. If you work on one large site with rough ground, choose crawler.

Real Customer Case – Saudi Arabia
A major road project in Riyadh, Saudi Arabia faced tough conditions. Temperature was over 45°C. Concrete was setting too fast. Manual work was nearly impossible.
The contractor used a YG-30 slipform curb machine.
Results:
- Paved an average of 1.5 kilometers of curb per day
- Machine kept working steadily in extreme heat
- Automatic controls kept the line straight and height correct
- Finished 20 days ahead of schedule
The project manager said: “If the machine can handle desert heat, it can handle any job site.”

Quick Selection Table
| Your project need | Recommended model | Why |
| Sidewalks, parking lots, small streets | YG-20 | Compact, wheeled, easy to move |
| Highways, main roads, barriers | YG-30 | Crawler, stable, high height capacity |
| Curb height under 600mm | YG-20 | Fits the capacity |
| Curb height up to 1100mm | YG-30 | Fits the capacity |
| Moving between many sites | YG-20 | Easier to transport |
| Working on one large site | YG-30 | Crawler stability for long jobs |
Concrete Curb Machine Price – What to Expect
Concrete curb machine price depends on model and features.
- YG-20 (wheeled): Lower investment
- YG-30 (crawler): Higher investment
Both machines pay for themselves through labor savings. A crew of 10 workers building curbs manually costs a lot per day. One machine and two workers do the same job faster.
The YG-20 is best for contractors starting out or working on smaller projects. The YG-30 is for contractors handling large-scale highway and municipal work.
