Is galvanized wire mesh resistant to fire

Galvanized wire mesh, known for its durability and corrosion resistance, is often used in a wide range of applications. This article aims to explore the fire resistance of galvanized wire mesh and its suitability for different fire-prone environments.

Composition and Coating:

Galvanized wire mesh consists of a base metal, typically steel or iron, coated with a layer of zinc. While zinc itself is not highly flammable, it does have a relatively low melting point. The thickness of the zinc coating on the wire mesh can impact its fire resistance properties. Thicker coatings generally provide better protection against fire.

Heat Resistance:

Galvanized wire mesh exhibits good heat resistance due to the presence of the zinc coating. The zinc layer acts as a heat barrier, reducing the transfer of heat to the base metal. This property can help delay the onset of structural failure in the wire mesh during a fire. However, it is important to note that galvanized wire mesh is not completely fireproof and has limitations in extreme fire conditions.

Fire Retardant Properties:

Galvanized wire mesh has inherent fire retardant properties. When exposed to fire, the zinc coating on the mesh releases zinc oxide, which forms a protective layer on the surface. This layer acts as a barrier, preventing oxygen from reaching the underlying metal and slowing down the combustion process. These fire retardant properties can provide valuable time for evacuation and firefighting efforts.
