Formwork System for Concrete Construction

Aluminium Formwork System

The advantages of the aluminium formwork system in construction:

1. Short period of construction. Aluminum formwork system is in the line of quick-dismantling formwork system. One layer of formwork can be completed in 4-5 working days and can be removed in 12 hours. 4 to 6 typical floors/month is achievable. So it is very cost effective and can greatly shorten the construction period.

2. Strong stability & high bearing capacity. Aluminum formwork is made of 6061-T6 aluminum alloy plate and aluminum alloy profile. When assembly finished, it will forms a integrated framework with high stability. The bearing capacity can reach 60KN/m², which can satisfy the supporting requirements of most buildings and no swelling occurred.

3. Better concrete finish after dismantling. You can save the plastering cost as the surface of the concrete after the dismantling is flat and smooth, which can basically meet the requirements of the decoration surface and the clear water concrete.

4. High cycle times & recycling value, reducing the average cost. A set of the normal aluminum formwork can be used repeatedly over 300 times. And the dimensions of most of the formworks which used in different structures are the same. It means that when you have a new different project, 70%-80% formworks of the last project could be reused. After formworks lost a value in usage, the aluminum material could be re-sold to the market with a high price.

5. Assembly more easily & high accuracy. Before construction, the engineers will design all the formworks needed in the project by CAD and the formworks are standardized, modular and systematic produced, thereby realize the integrated one-time concrete pouring of wall formwork system, floor formwork system and supporting formwork system. All the plates and parts are numbered and do integral trial assembling in factory, eliminating all the errors and omission than may occur before shipping to the construction sites. Workers can assembly the formwork according to the numbers on the formwork, reducing the man-made mistakes. 

6. Construction more conveniently and effectively. The aluminium formwork system is easy to be assembled with the average weight of 20kgs, which can totally be removed and assembled by hand, without any machines assist. The simple system of pins & wedges makes assembly easier. The workers just need a spanner and a hammer to assemble the whole system easily. Its average working rate per worker is 20-30 square meter.

7. Wide applications. Aluminium formwork system is suitable for all building components, such as walls, floors, pillars, beams, staircases, windows, balcony, etc. All these components can be completed one-time.

8. Safe & no construction waste. As it has higher rate in recycling, the aluminium building formwork is facile to remove with no waste left, leaving a clear and tidy working site. There is no risk of fire. So aluminum formwork can fully meet the requirements of green construction standard.

9. Wider working space. Contrast to traditional formwork systems, aluminum formwork system use less supporting props, it leave more space for walking or materials transportation.

10. Environmental friendly. All of the materials used in the aluminum formwork belong to the recycled materials, which conforms to the regulations on the energy saving, environmental protection and low carbon emission.
