Our rebar stirrup bending machine represents enterprise-grade automation technology, delivering exceptional performance for construction and infrastructure projects worldwide. This fully automatic servo-controlled system processes φ10–32 mm diameter steel with bending angles from 0 to 180°, achieving remarkable production efficiency of 120–160 pieces per hour.
With demonstrated victory over about 100 nations and trusted organizations with China Railroad Bunch, CRCC, CSCEC, and CCCC, our progressed twisting arrangements meet the requesting prerequisites of high-speed railroads, bridges, burrows, and atomic control ventures. The machine highlights double-head synchronous twisting innovation that guarantees exactness inside ±0.5° point exactness and less than 1mm length error.
Modern construction demands efficiency without compromising quality. Traditional manual bending methods create bottlenecks in production schedules and introduce costly material waste.
Our rebar stirrup bending machine transforms your steel processing operations through intelligent automation. The PLC touch screen control system stores multiple parameter sets, enabling quick specification switching between different rebar sizes and shapes. You can process complex stirrups, hooks, and special-shaped reinforcements with consistent accuracy that manual methods simply cannot achieve.
The double-sided exactness twisting framework handles numerous rebars simultaneously—up to 6 bars of φ10–12mm distance across in one cycle. This capability drastically increments throughput whereas keeping up the tight resiliences required for auxiliary judgment in high-rise buildings and bridge construction.

Labor and Fetched Reduction
You can supplant 5–8 manual specialists with fair one machine administrator. Unused staff ace the framework inside one hour much obliged to the instinctive touch screen interface. This emotional lessening in labor prerequisites interprets straightforwardly to lower operational costs and progressed benefit margins.
Superior Accuracy and Consistency
The servo drive framework conveys bowing point blunders inside ±0.5° and length mistakes less than 1mm. This level of accuracy guarantees each piece meets basic designing details. You kill the dimensional varieties inborn in manual twisting that can compromise load-bearing capacity.
Maximum Production Efficiency
Double-head synchronous bending technology enables one-step forming of complex shapes. The rebar stirrup bending machine processes 120-160 pieces per hour depending on shape complexity. Your production schedules become more predictable, and project deadlines easier to meet.
Reduced Fabric Waste
Intelligent parameter capacity and computerized preparing diminish human blunder and lower rebar misfortune by over 10%. For large-scale ventures preparing hundreds of tons of steel, this squander lessening creates considerable fabric taken a toll savings.
24-Hour Nonstop Operation
The heavy-duty machine body with torsion-resistant structure keeps up steady execution amid amplified generation runs. You can plan overnight operations to maximize gear utilization and quicken venture timelines without quality degradation.

Prefabricated Concrete Plants
In climate-controlled offices creating standardized components, our framework conveys the extraordinary repeatability required for precast bars and heaps. The parameter capacity highlight guarantees indistinguishable details over thousands of pieces.
Bridge and Burrow Infrastructure
Complex designing ventures request high-strength HRB500 rebar shaped into large-format stirrups. Our machine handles these challenging materials whereas keeping up the exactness essential for seismic stack resistance and basic inspections.
High-Rise Development Sites
Urban development benefits from onsite generation capabilities. You dispose of lead times related with outside manufacture and decrease coordinations costs in tight development impressions. Real-time generation of customized fortification cages keeps your extend moving forward.
Rebar Handling and Dissemination Centers
Centralized offices serving different ventures require flexible hardware. The wide preparing run from φ6–50mm with speedy determination exchanging lets you fulfill different client orders effectively from a single machine.
