High-rise construction projects require advanced formwork solutions that can support fast construction cycles, accurate concrete forming, and safe working conditions at height. As building structures become taller and project schedules become more demanding, traditional formwork methods often need to be replaced by more integrated systems that improve efficiency and construction control.
A Gang Form System is an integrated large-panel formwork solution designed mainly for high-rise exterior wall construction. By combining steel formwork, external working platforms, and anchoring components into one complete unit, the system allows contractors to carry out repeated floor-by-floor construction with improved efficiency and consistency.
Unlike conventional formwork systems that require frequent dismantling and reassembly, a Gang Form System is designed as a climbing construction solution. After each concrete pouring cycle, the complete unit can be lifted and repositioned for the next level, creating a continuous workflow for high-rise projects.
GETO provides green building formwork and scaffolding solutions, including steel formwork, climbing systems, and other advanced construction technologies. The company’s Gang Form System is developed to support high-rise residential, commercial, industrial, and infrastructure construction with reliable performance and professional engineering support.
Definition and Context of Gang Form System
A Gang Form System is a large-scale integrated formwork system mainly used for exterior wall construction in high-rise buildings. The system combines several key components into one coordinated construction unit, including steel formwork panels, integrated working platforms, connection systems, and anchor systems.
The purpose of this integrated design is to create a complete working environment for both concrete forming and high-altitude construction operations. The steel formwork provides the required shape and support for concrete structures, while the external platform allows workers to safely complete installation, inspection, and related construction activities.
The anchoring system plays an essential role by connecting the Gang Form unit to the building structure. It provides stable support during concrete pouring and creates reliable fixing points during lifting and climbing operations.
Because of its integrated structure and repeated climbing capability, the Gang Form System is widely used in projects where exterior wall construction needs consistent quality and efficient floor cycles.

How Does a Gang Form System Work?
The working principle of a Gang Form System is based on a repeated lifting and construction cycle. After the system is installed and fixed in position, concrete is poured into the steel formwork to create the required exterior wall structure.
Once the concrete reaches the required strength, the Gang Form unit is released and lifted upward as a complete assembly. The system is then secured at the next construction level and prepared for another concrete pouring cycle.
Overall Lifting Process
The complete Gang Form unit is usually moved by crane equipment. Instead of removing individual panels and rebuilding the formwork on every floor, the integrated system allows faster relocation and more consistent positioning.
Before lifting, several preparation steps are required:
- Checking the anchor connections
- Confirming structural stability
- Installing braces and steel wire ropes
- Verifying the alignment of the formwork unit
After the unit reaches the next level, the anchor system secures the structure and prepares it for the following construction stage.
Floor-by-Floor Climbing Construction
One of the major advantages of the Gang Form System is its ability to support continuous vertical construction. The system enables repetitive floor cycles and can support 2–4 levels of simultaneous operation depending on project requirements.
This makes it particularly suitable for high-rise residential towers and commercial buildings where exterior wall structures are repeated across many floors.
Key Design Factors of Gang Form System
A high-performance Gang Form System depends on the coordination of multiple structural components. Each element contributes to concrete quality, operational safety, and construction efficiency.
Steel Formwork System
The steel formwork system is the core forming component of the Gang Form System. It provides structural support during concrete pouring and maintains accurate dimensions after repeated use.
GETO steel formwork uses Q235 high-strength carbon steel with optimized panel thickness and surface treatment. The rigid steel structure improves concrete surface quality, reduces deformation, and supports repeated construction cycles.
Integrated Working Platform
The integrated working platform is installed outside the steel formwork and moves together with the climbing unit. It provides workers with access routes, operation space, material placement areas, and safety protection during exterior wall construction.
The platform includes anti-slip steel decking, guardrails, protective mesh, and access ladders. This integrated arrangement creates a safer and more organized working environment for high-rise operations.
Connection and Anchor System
The connection and anchor system is the main load-bearing and positioning structure of the Gang Form System. It connects the formwork, platform, and supporting components while resisting fresh concrete pressure during casting.
The system also helps control wall thickness, vertical alignment, and structural positioning. Reliable anchor design is essential for safe lifting, climbing operations, and long-term construction stability.
