The overall fire resistance of a structure is not directly affected by steel formwork, as its main purpose is temporary support during concrete pouring and construction. The fire resistance of a structure is generally determined by the construction materials, including the type of concrete, insulation, and fireproofing systems.
However, steel formwork can indirectly contribute to the fire resistance by ensuring proper placement and compaction of the concrete, which is crucial for achieving the desired fire resistance rating. When mixed and compacted correctly, the strength and durability of the concrete can improve the overall fire resistance of the structure.
Moreover, steel formwork can provide a smooth and uniform surface finish, which facilitates the application of fireproofing materials. Fireproofing coatings or sprays are often used to enhance the fire resistance of structural elements like beams and columns. The smooth surface offered by steel formwork helps ensure an even and effective application of these fireproofing materials, thus further improving the fire resistance of the structure.
It is important to remember that although steel formwork itself is not fire resistant, it is usually removed once the concrete has cured. The final fire resistance of the structure is determined by the materials used in its permanent construction.

Fire resistance primarily depends on the materials used for structural elements, such as beams, columns, and floors. However, steel formwork can indirectly contribute to fire resistance by ensuring the proper placement and alignment of concrete during construction, which can enhance the overall structural integrity and fire resistance of the building.
