What material should be used to protect piping passing through walls?

Using steel to protect piping as it passes through walls is highly effective due to its durability and strength. Steel is resistant to impact and damage, making it ideal for safeguarding pipes from external forces that might occur in a construction environment. Moreover, steel can withstand changes in temperature and does not degrade over time, providing long-lasting protection.

In construction applications, steel sleeves or piping are commonly utilized as a means of both protection and structural integrity. They can help prevent corrosion, reduce vibration, and allow for thermal expansion without compromising the integrity of the piping system.

While other materials, such as wood, plastic, and aluminum, may offer certain benefits, they do not provide the same level of strength or protection against physical damage and environmental factors. For instance, wood can rot or be easily damaged, plastic may not withstand extreme temperatures or pressure, and aluminum is generally less robust compared to steel in high-stress applications. Thus, steel is the preferred material for ensuring that piping is adequately protected as it transitions through walls.
