What is a Stirrup Bending Machine?
A stirrup bending machine is one of the most important equipment in construction and civil engineering projects, used for bending rebar to produce stirrups. A stirrup is a loop of steel rebar that wraps around longitudinal bars (main reinforcement) and plays a vital role in strengthening concrete structures.
Main function of stirrups: Preventing lateral buckling of longitudinal bars, increasing shear resistance of columns and beams, and holding reinforcement in place during concrete pouring. Without stirrups, concrete structures would not have sufficient strength.
Types of Stirrup Bending Machines
Stirrup bending machines come in different types: electric, gear, hydraulic, and manual. The right choice depends on project volume, rebar size, and budget.
Electric Stirrup Bender
For medium to large projects
Size: 4-12 mm
Gear Stirrup Bender
High power for heavy rebar
Size: 4-16 mm
Hydraulic Stirrup Bender
Strong performance for large sizes
Size: 6-20 mm
Manual Stirrup Bender
Economical for small projects
Size: 4-10 mm
Electric Automatic Stirrup Bender
Introduction and Features
Electric automatic stirrup bender is the most commonly used type in Iranian construction projects. This machine runs on an electric motor and has the ability to adjust bending angle, stirrup length, and repetition count.
Main Features:
- High speed: Production of 40-60 stirrups per minute
- Precision bending: Accurate angles of 45°, 90°, and 135°
- Dimension adjustment: Length adjustable from 15 to 150 cm
- Simple operation: Control via digital panel or push buttons
- Easy maintenance: Requires simple periodic service
Gear-Type Stirrup Bender
Introduction and Features
Gear-type stirrup bender is equipped with an industrial gearbox that increases bending power. This type of machine is recommended for heavy projects and continuous operation.
Advantages:
- High bending power: Suitable for rebar up to 16mm
- Greater durability: Industrial gearbox has longer life
- Continuous operation: Suitable for 8-hour daily use
- Stronger structure: More rigid frame for heavy work
Hydraulic Stirrup Bender
Introduction and Features
Hydraulic stirrup bender uses a hydraulic system to generate bending force. This type has high power and is suitable for heavy rebar (up to 20mm).
Main Applications:
- Large civil projects: Heavy foundations, bridges
- Stirrup production factories: High-volume production
- Sites with power limitations: Can be used with generator
Benefits of Stirrup Bender Machine

💰 Reduced Waste
Precise machine bending minimizes waste from human errors. Each stirrup cut and bent to exact length.
🛡️ Increased Safety
Eliminates risks of fatigue, back injury and accidents from manual lever bending.
Manual (Column) Stirrup Bender
Introduction and Features
Manual stirrup bender is the simplest and cheapest type. This machine works with the operator's physical force and is suitable for small projects or workshops with limited volume.
Specifications:
- Reasonable price: Cheapest option in the market
- Simple maintenance: Almost no service required
- Portable: Weight less than 100 kg
- Suitable for: Low-volume projects and small workshops
Stirrup Applications in Concrete Structures
Stirrups are used in various concrete structures. Understanding their correct applications helps choose the right machine.
Columns
In concrete columns, stirrups wrap around longitudinal bars and prevent their buckling. Stirrup spacing in columns is usually between 10-25 cm and decreases near the column ends.
Beams
In beams, stirrups play a role in resisting shear forces. The number and spacing of stirrups in beams is determined based on structural calculations and directly affects structural safety.
Foundations
In strip and raft foundations, stirrups are used to reinforce concrete against bending and shear forces. Stirrup size in foundations is usually larger (10-16mm).

Benefits of Using Stirrup Bending Machine
Using a stirrup bending machine instead of manual bending has multiple benefits for contractors and construction projects:
Time and Labor Cost Savings
One skilled operator can do work that previously required 3-4 workers. Machine production speed is 4-5 times faster than manual bending.
High Precision and Uniformity
All stirrups are produced with identical dimensions and angles. This uniformity is highly important in structural calculations and ensures final structure quality.
Reduced Rebar Waste
Precise bending with machine minimizes waste from human errors. Each stirrup is cut and bent to exact length.
Increased Workshop Safety
Manual stirrup bending with lever and physical force has risks like fatigue, back injury, and accidents. Stirrup bending machine eliminates these hazards.
Important Tips for Choosing Stirrup Bending Machine
Choosing the right stirrup bending machine is a decision that directly affects project cost and quality. Before buying, check the following:
1. Project Volume
For small projects with less than 500 stirrups, manual or electric is sufficient. For medium projects (500-5000), electric or gear type is suitable. Large projects require gear or hydraulic type.
2. Rebar Size
Common rebar in Iran varies from 8 to 20mm. Make sure the chosen machine supports the required project sizes. Rebar size 16 and above needs a more powerful machine.
3. Budget
Electric automatic machine has the best price-to-performance ratio. If budget is limited, consider manual machine but note that additional labor cost may offset initial savings over time.
4. Workshop Space
Larger machines need more space. Also, 3-phase machines (380V) need industrial power. Before buying, ensure appropriate power is available at the workshop.
5. After-Sales Service
Iranian-made machines usually have better after-sales service. Check spare parts availability and ensure repair representatives exist in your city.

How to Operate Stirrup Bending Machine
General Steps for Operating Stirrup Bending Machine:
Rebars Preparation
Cut rebar to desired length. Stirrup length is calculated based on form dimensions and concrete cover.
Machine Setup
Adjust bending angle (90° or 135°), stirrup arm lengths, and repetition count. On digital models, settings are done from panel.
Placing Rebar
Place rebar between two bending arms (disc and mold). Rebar should be centered for symmetric bending.
Start Bending
Press start button. Bending disc starts rotating and bends rebar to desired angle.
Removing Stirrup
After bending is complete, remove stirrup from machine and place in designated area.
Maintenance and Service
Regular maintenance of stirrup bending machine increases machine life and prevents unexpected breakdowns:
Daily Service:
- Clean rebar filings from machine surface
- Check tightness of screws and connections
- Lubricate moving parts
Weekly Service:
- Check belt tension (in belt models)
- Clean motor air filter
- Check button and sensor functionality
Monthly Service:
- Change gearbox oil (in gear models)
- Check bending disc alignment
- Inspect wiring and electrical connections
Frequently Asked Questions
What is the difference between electric and gear-type stirrup bender?
The main difference is in power transmission system. In electric stirrup bender, motor power is transferred directly to bending disc. In gear type, an industrial gearbox is placed between motor and disc, which: creates more bending power, puts less pressure on motor, increases machine life, and is suitable for larger rebar.
Does electric stirrup bender need 3-phase power?
Yes, most electric and gear-type stirrup benders need 3-phase power (380V). Some smaller models work with single-phase power (220V) but have less power. Before buying, ensure appropriate power type is available at your workshop.
What type of machine is suitable for a residential project?
For most residential projects, electric automatic stirrup bender with 4-12mm size is sufficient. Stirrup volume in these projects is usually medium and this machine offers the best price-to-performance ratio.
Does the machine come with warranty?
Machine warranties vary by brand. Usually 6 months to 1 year warranty is provided for motor and gearbox. Alborz Ghaleb offers 1-year warranty with after-sales service.
Is training provided for machine operation?
Yes, upon delivery, Alborz Ghaleb technical experts provide complete training on machine operation, settings, and maintenance. This training usually takes 1-2 hours.
