The thickness of wooden formwork plays a pivotal role in its performance depending on the specific application. Here's how to select the right thickness for various scenarios:

- Standard Applications: For typical structural elements such as floor and column formwork, a thickness range of **12mm to 18mm** is commonly used. This provides adequate strength without excessive weight.

- Load-Bearing Sections: When dealing with substantial loads, such as side boards of a beam, it is crucial to use **20mm** thickness. In contrast, the base of beams may require more substantial material, up to **40mm**, especially if using pine wood.

- Thin Options: For temporary repairs or smaller components, thinner boards in the range of **9mm to 14mm** are suitable. These options are ideal for side molds and minor fixes where less strength is needed.

Selecting the right dimensions and thickness of wooden formwork is critical to the overall success of any construction project. Understanding the common sizes and knowing which thickness to use depending on the application can mitigate risks associated with structural integrity.
