● Steel formwork vs timber formwork

Steel formwork and wooden formworks are two commonly used formwork materials in the building construction. They have their own advantages and disadvantages.

The advantages of steel formwork:
1. High strength: Steel formwork is made of high strength steel, has good resistance to compression and bending, can bear large construction load.

2, Strong durability: Steel formwork has long service life, can be reused for many times. It is not easy to broken in use, saves the formwork investment and maintenance cost.

3 High construction efficiency: Steel formwork can achieve overall assemble and disassemble, easy to install, can greatly short the construction period, improve construction efficiency.

4. Flat formwork surface: Steel formwork has excellent manufacture process, the formwork surface is very smooth and flat, can meet the requirements of high demand building construction.

5. Good environmental performance: Steel formwork can reuse for many times, which can ease the shortage of forest resources to a certain extent.

Steel formwork disadvantages:
There are two disadvantage of steel formwork:
1, Has high requirement on building standardization: Steel frame formwork usually be designed at advance and carry out standardized production, this means, if the building structure is not standard enough, for example, if it has too many components, it has to modify the steel frame formwork, this will take more time and cost.

2, High requirement on management: Steel formwork is very heavy, need to be installed with a crane, so has high requirements on worker’s operation and construction skill. If the mangers are not skilled enough, the construction efficiency may lower than wooden formwork.

The advantages of wooden formwork:
High usage efficiency: The manufacture of wooden formwork is simple, it is easy disassembled, has high construction speed.

Good environmental performance: Wooden formwork mainly made of natural wooden and environmental coating, etc. it has few pollution to the environment during the construction.

Wide application range: Wooden formwork can be used to various parts of concrete structure construction, and has high customization degree.

Relatively low cost: Compare with other material formwork, such as steel formwork, aluminum formwork, the cost of wooden formwork is relatively lower.

The disadvantages of wooden formwork:
Easy to moisture and deformation: Wooden formwork is easy to be affected by humid environment, if not store correctly, it will suck the water and cause deformation, finally reduce its service life.

Easy to cause fire: The wooden formwork is easy to be fired, has bad anti-fire performance, and also easy to affect the surrounding environment.

Weak tightness: The interface of wooden formwork has weak tightness, which is easy to cause the concrete leakage, lower the project quality.

In general, both steel formwork and wooden formwork has their own advantages and disadvantages, users can make choice according to the special project situation, such as the standardization degree of building structure, construction period, environmental requirements, etc.
