Hospital doors are an important part of a healthcare facility and need to be designed to meet health, safety and functionality requirements. Common types include automatic sliding doors, manual swing doors and radiation resistant doors. Materials are mostly stainless steel or antimicrobial coatings, which are easy to clean and disinfect. Doors need to be soundproof, fireproof, anti-bacteria and other functions, and some areas such as operating rooms and isolation wards also need airtight design.
