GETO Tunnel Formwork Solutions
Core Advantages of the Tunnel Formwork System
Extremely High Construction Efficiency
By enabling the integrated casting of walls and slabs, the system eliminates the alternating sequence of erecting and stripping formwork for separate components. With skilled operation, an extremely short construction cycle per floor can be achieved, making it ideally suited for large-scale, repetitive residential projects.
Exceptional Structural Quality and Seismic Resistance
Integrated casting means the absence of cold joints. This monolithic, box-like configuration boasts exceptional geometric precision and structural rigidity, demonstrating superior performance under seismic loads.
Reduced Comprehensive Costs
· Reduced Labor: The simplification of construction processes lowers the reliance on highly skilled tradespeople.
· Material Savings: A high turnover rate means that the material cost amortized per square meter is significantly reduced.
· Plaster-Free Finish: The exceptionally high surface flatness allows interior walls to proceed directly to the putty application stage, bypassing the need for plastering.
· High Safety Standards: The system is equipped with comprehensive external operating platforms and fully enclosed auxiliary systems, significantly mitigating the risk of falls from heights and making the formwork construction industry a safer environment.
Aluminum Tunnel Formwork vs. Steel Tunnel Formwork
To meet the diverse requirements of different projects, GETO offers two distinct tunnel formwork solutions: one utilizing aluminum alloy and the other utilizing steel.
| Comparison: Aluminium vs. Steel Tunnel Formwork | ||
| Feature | Aluminium Tunnel Formwork | Steel Tunnel Formwork |
| Structure Type | Integrated Aluminium Panels | Monolithic Steel Formwork |
| Weight | Lightweight (Less Crane Power) | Heavy (Requires High-Capacity Crane) |
| Installation Speed | Fast Overall Installation | Simple Process, Low Labor Force |
| Reusability | Very High Material Reuse | Tightly Spliced, Durable |
| Assembly Flexibility | Flexible and Simple Process | Large-Scale Mechanized Dismantling |
| Scrap Value | High Recovery Value | Standard Scrap Value |
| Construction Environment | Wide Range of Applications | Excellent Insulation for Winter |
The core advantages of the aluminium alloy solution lie in its "lightness" and "flexibility." It imposes lower requirements on tower crane specifications, and—thanks to the physical properties of aluminium—its assembly and dismantling are extremely flexible, making it suitable for most high-rise residential projects. Furthermore, its high residual value makes asset recovery in the project's later stages more cost-effective.
The steel solution, conversely, emphasises "rigidity" and "strength." It boasts excellent structural integrity and is highly resistant to deformation. Particularly during winter construction, the superior thermal retention properties of steel—when combined with a heating system—ensure more effective and reliable concrete curing.

FAQ
Q1: What is a tunnel formwork system?
A: It is an integrated system that combines formwork for both walls and floor slabs, allowing for the monolithic casting of these structural elements within a single operational cycle.
Q2: How does tunnel formwork work?
A: Pre-assembled tunnel units are positioned to facilitate steel reinforcement tying and concrete pouring. Once the concrete has cured, the formwork units are stripped and moved—as complete assemblies—to the next floor for reuse.
Q3: What are the advantages of tunnel formwork?
A: Key advantages include rapid construction speeds, superior seismic resistance, reduced labor costs, and high-quality concrete surface finishes (often eliminating the need for subsequent plastering).
Q4: Is tunnel formwork suitable for high-rise buildings?
A: It is highly suitable. It is particularly advantageous for residential complexes and hotels with standardized floor layouts; the greater the number of floors, the lower the amortized cost per floor, making the benefits increasingly pronounced.
Q5: What is the difference between aluminum and steel tunnel formwork?
A: Aluminum alloy systems are lighter, more flexible, and retain a higher residual value. Steel systems, conversely, offer greater rigidity and exceptional resistance to deformation, while also performing better in terms of thermal insulation during winter construction.
