What is the common material used for escalator treads?

Escalator treads are primarily made of steel due to its durability and strength. Steel is capable of withstanding the heavy foot traffic that escalators experience and helps to ensure safety and stability during operation. The surface of the steel treads is often designed with grooves or patterns to provide traction, reducing the risk of slips and falls. Additionally, steel treads are resistant to wear and tear, which is crucial for the longevity and reliability of escalators in public and high-traffic environments. This selection makes steel an optimal choice compared to other materials that may not offer the same level of structural integrity or safety features for escalator designs.
