The wooden formwork used on construction sites is composed of a panel and a support system. It is a commonly used material for pouring concrete in building construction. In this article, ZMADTO will introduce you to five types of wooden formwork used in construction sites.

Ordinary plywood formwork: It uses miscellaneous woods such as poplar and pine as core materials. It is made by gluing and pressing multiple layers of veneers, with a thin wood veneer covering the surface. It is suitable for low-rise buildings, temporary facilities, or small concrete components. However, the number of turnover times is only 3 - 5 times, and it is prone to deformation and delamination when getting wet.

Film-faced plywood formwork: A phenolic resin film is covered on the surface of ordinary plywood. It features water resistance, wear resistance, and a smooth surface. The number of turnover times is increased to 8 - 12 times. It is widely used for pouring beams, columns, floor slabs, and shear walls in high-rise buildings.

Fair-faced building formwork: It has a flat and smooth surface. The concrete poured with it has high surface quality. It has good strength and toughness. High-quality products have better turnover times and durability. It is suitable for scenarios with high requirements for the concrete appearance.

Eucalyptus formwork: Made from eucalyptus, it is relatively heavy and brittle. It is rarely used alone and is often combined with other woods to enhance its performance.

Pine/poplar formwork: It is a commonly used material as a core material or basic formwork. Pine has higher strength, while poplar has a lower cost. They are mostly used in foundation construction or support systems. For example, 20 mm-thick pine or poplar boards are commonly used for the side panels of ground beams.

Wooden formwork is lightweight, easy to process, and has a moderate cost. When choosing it, careful considerations should be made in combination with the project type, environmental humidity, turnover requirements, etc.
