What are the building formwork materials?

Building formwork can be made of various materials. The following are common building formwork materials:

Wood: Wood is one of the most commonly used building formwork materials. Commonly used wood is cork, pine, birch and so on. The wood formwork has moderate strength and rigidity, and is relatively easy to process and adjust its size.

Plywood: Plywood is a kind of board made of multiple layers of thin wood chips bonded by adhesive. With high strength and stability, it is often used to make large-area building templates.

Steel plate: Steel plate formwork has high strength and good durability, and is suitable for the construction of large and high-rise buildings. Steel formwork is usually prefabricated and can be quickly installed and removed.

Aluminum alloy: aluminum alloy formwork has light weight and good corrosion resistance, and is suitable for construction sites that need frequent movement and installation.

Polymer: Polymer templates are usually made of plastic or polypropylene. They are light, easy to disassemble and reuse, and can produce a smooth concrete surface in some cases.

Fiber reinforced composites: Fiber reinforced composites such as glass fiber reinforced polymers are also used as building formwork materials. They have high strength, light weight and corrosion resistance.

When selecting building formwork materials, factors such as construction requirements, structural load, surface requirements, economy and sustainability need to be considered. Construction teams, designers and engineers usually choose the most suitable building formwork materials according to specific engineering requirements and budgets.
