Steel is a common material used to construct a pressure gauge due to its strength and durability. Pressure gauges need to withstand high pressures and potential impacts in various environments, making steel an ideal choice because it has excellent tensile strength and resistance to deformation or failure.

Steel also provides good corrosion resistance, especially when alloys or coatings are applied, allowing the gauges to maintain their accuracy and integrity over time, even when exposed to harsh chemicals or environmental conditions. Additionally, steel can endure a wide range of temperatures, which is crucial for maintaining accuracy in pressure readings.

While other materials like plastic or glass might be used in specific applications or for certain components, steel is preferred for the main body of the gauge, especially in industrial settings where reliability is critical.
