Abstract Handrails in schools are touched by hundreds of students daily, creating a high-contact surface that can facilitate the spread of bacteria and increase the risk of illness. Traditional handrails, often made of smooth metal or grooved wood, may trap bacteria and be difficult to clean effectively. This project aims to identify materials, textures, and designs that minimize bacterial contamination while maintaining safety and functionality. By systematically testing different handrail materials, surface textures, geometries, and additional features, we aim to develop a handrail that is cleaner, safer, and easier to maintain in school environments.
