Let's first clarify what this machine does. In construction projects, rebar cages are the core structural framework for cast-in-place concrete piles, diaphragm walls, and similar structures. In the past, rebar cages were fabricated entirely by manual welding-slow, labor-intensive, and prone to quality issues. Today, with the introduction of the Xuhui Rebar Cage Welding Machine, this automated solution has significantly improved both production efficiency and product quality. Below is a closer look at how it performs across different job sites.
- High-Rise Building Foundations
For underground garages and pile foundation works of super-high-rise buildings, rebar cage demand is enormous, with highly varied specifications.Take a 300-meter-tall building project in Shenzhen as an example. The project required more than 300 sets of rebar cages, each 1.2 m in diameter and 15 m in length. With traditional manual welding, rebar spacing was inconsistent and weld points were prone to failure, making quality control extremely difficult.
With the Xuhui rolling cage welding machine, the situation changed completely. Servo motors drive the spiral winding rollers, keeping rebar spacing errors strictly within ±2 mm. Combined with the automatic feeding system, the machine can produce 12 rebar cages per day, saving about 60% of the time compared with manual welding. It also supports rebar diameters from Φ12 to Φ32 mm, easily handling various specifications.
- Bridge Engineering
Bridge construction is known for its extremely high requirements in both precision and efficiency. In a domestic river-crossing bridge project, the main pier rebar cages reached 2.5 m in diameter and 40 m in length. Manual welding previously required 3–5 skilled workers working for over 10 hours, yet spacing accuracy was still difficult to guarantee.
After adopting the Xuhui rebar cage welding machine, the CNC system automatically positioned the rebars, with spiral winding speeds reaching 1.5 m/min. The fabrication time for a single rebar cage was reduced to just 2 hours. Weld strength increased by 40%, and diameter deviation was controlled within ±3 mm, fully meeting the stringent uniformity requirements of bridge projects.
- Metro And Tunnel Projects
Support structures in metro and tunnel construction demand extremely high standards for verticality and welding strength.
Compared with manual welding, rebar cages produced by the rolling welding machine have fewer weld points while achieving more uniform and consistent weld strength. Overall construction efficiency is increased by more than three times, providing a more reliable quality guarantee for metro and tunnel foundation works.
- Water Conservancy And Hydropower Projects
In water conservancy projects, rebar cages are widely used in dam cutoff walls and riverbank slope protection.
Manually fabricated rebar cages often show deviations of up to ±10 mm. With the rebar cage rolling welding machine, automatic winding and welding reduce deviations to ±3 mm, while significantly enhancing the overall stiffness of the rebar cage. More importantly, during underwater concrete pouring, the machine-made cages feature uniform structures and strong welds, effectively reducing the risk of concrete loss and greatly improving construction progress.
Product Display
The Xuhui Rebar Cage Rolling Welding Machine, with its fully automated operation, high precision, and standardized production, has long been recognized as a high-efficiency solution in construction, bridge, and water conservancy projects.
Whether it's large-scale, standardized rebar cage production for major infrastructure projects or customized requirements in complex geological conditions, the machine uses CNC-controlled operations to ensure precise rebar cage quality while significantly reducing labor costs.
