The rebar straightener is an essential machine in the construction and steel processing industries. It is mainly used to straighten and process coiled or bent steel bars into uniform, straight lengths for further cutting, welding, or construction use. Whether you’re dealing with small-diameter rebars or heavy steel rods, a rebar straightening machine ensures high precision, fast operation, and consistent product quality.
Why You Need a Rebar Straightening Machine
In modern construction and steel fabrication, precision and efficiency matter. Coiled or bent rebars can’t be used directly for reinforcement; they must be straightened first.
That’s where a rebar straightener comes in — it turns tangled coils into perfectly straight, ready to use steel bars. Choosing a reliable rebar straightening machine ensures smoother operations, consistent quality, and lower labor costs.
Raw Materials & Finished Products of Our Rebar Straightener
The steel bar straightening machine is designed to handle various raw materials such as:
- Coiled rebars (6-25 mm)
- Deformed or bent steel rods
- Round metal bars and wire rods
After straightening, the finished products feature:
- Smooth, uniform surface without deformation
- Accurate cutting length (commonly 500-2000 mm)
- Ready for welding, construction, or reprocessing
These finished bars are ideal for reinforced concrete, structural steel production, and manufacturing industries.
How the Rebar Straightener Works
Inside the rebar straightener machine, the steel bar passes through a set of precisely arranged rollers that rotate at high speed.
Each bar is corrected multiple times (typically 5-6 holes, 20 passes per cycle) to remove twists and curves.
The bar straightening machine then automatically feeds the bar into a cutting unit, where it is cut to the preset length.
The process is fully automatic — combining straightening, measuring, and cutting in one continuous operation. This not only improves accuracy but also boosts productivity for steel processing lines.
Multiple Bar Straightener Machine Models Available
Our rebar coil straightening machine offers multiple models to fit different rebar diameters and production needs. We can also provide customized straighteners for your needs. (Please feel free to contact us)
| Model | Straightening Diameter(mm) | Straightening Holes | Cutting Length(mm) | Motor Power(kW) | Machine Weight(kg) | Machine Dimension (mm) |
|---|---|---|---|---|---|---|
| ET-6-10 | 6-10 | 5 holes*20 passes | 500-2000 | 4 | 570 | 1100*720*1150 |
| ET-6-14 | 6-14 | 5 holes*20 passes | 500-2000 | 5 | 730 | 1200*790*1220 |

| ET-14-25 | 14-25 | 6 holes*20 passes | 500-2000 | 15 | 980 | 1550*890*1600 |
Custom configurations available for larger diameters or specific steel materials.
Why Quality Matters — Good vs. Poor Straightening Machines
Not all rebar straighteners are built the same.
Poor-quality machines often lead to bent results, rough surfaces, frequent downtime, and inaccurate cutting — wasting raw materials and increasing maintenance costs. By contrast, a high-quality steel rod straightening machine delivers:
- Perfectly straight bars with clean, smooth surfaces
- Consistent cutting length with minimal waste
- Stable operation and long service life
- High working speed and precision rollers
That’s why professional builders and steel processors choose our hydraulic rebar straightener — engineered with durable rollers, heavy-duty frames, and precision control systems.
