Steel formwork refers to the use of steel panels, frames, and props to create a temporary mold or framework for pouring concrete structures. It is a popular choice for constructing large and complex structures such as high-rise buildings, bridges, and tunnels.

The use of steel formwork offers several advantages over traditional formwork materials like wood or plywood. Steel is more durable and long-lasting, making it a cost-effective choice for larger construction projects. It is also reusable, which helps reduce construction waste and increases efficiency. Steel formwork can be easily assembled and disassembled, making it a convenient option for construction sites that require frequent changes.

However, steel formwork is also heavier and more expensive than other materials. It requires specialized equipment and skilled labor to install and remove, which can increase the overall cost of a project. Additionally, steel formwork can be more difficult to customize or modify on-site, which can limit its versatility in some construction scenarios.
