Core materials of GETO Aluminium Formwork Systems
As leading manufacturer of aluminium formwork in China, GETO Group provides a comprehensive ecosystem that integrates material excellence, engineering innovation, and digital management. With 12 production bases globally and an annual capacity of 5,000,000 square meters, GETO stands as a global expert in "making drawings happen." The company has successfully delivered projects in over 70 countries, demonstrating its ability to adapt to diverse building codes, safety standards, and local construction practices.
Our core material of aluminium formwork systems is 6061-T6
The core of any high-performance formwork system lies in its material composition. GETO utilizes 6061-T6 aluminium alloy, an aerospace-grade material characterized by its exceptional strength-to-weight ratio and durability.

Weight and Efficiency Comparison (H3)
A critical factor in reducing equipment dependency and accelerating assembly is the weight of formwork panels. The following comparison illustrates why aluminium is the optimal choice for high-rise construction:
GETO Aluminium Panels: 25–27 kg/m²
Steel Panels: 35–85 kg/m² (depending on thickness and profile)
Timber Panels (with steel or aluminium framing): 20–30 kg/m² but with significantly lower durability
The natural oxide layer that forms on 6061-T6 aluminium provides excellent corrosion resistance, even in coastal environments with salt-laden air or on projects using chemical concrete admixtures. Unlike steel formwork, which requires regular painting or galvanizing to prevent rust, aluminium formwork maintains its surface integrity with minimal maintenance. This durability translates directly into lower long-term ownership costs and more predictable project outcomes.
The lightweight nature of the GETO system allows for manual handling and positioning. A typical two-person crew can manage a full-sized wall panel without mechanical assistance. This eliminates the need for tower cranes for basic formwork assembly, significantly lowering equipment rental costs and freeing crane capacity for critical lifts such as rebar bundles or concrete buckets.
GETO's extrusion manufacturing achieves accuracy within ±0.5mm for all profiles. This precision ensures that when panels are locked together using a precision-engineered pin-and-wedge system, the entire formwork assembly behaves as a single, rigid structural unit. Gaps between panels are minimized, which directly contributes to the high-quality concrete finish that eliminates the need for plastering.
