Types of Elevator Doors Based on Movement
Elevator doors can be categorized based on their types of movement, including side sliding doors and center parting doors. Each type offers distinct advantages and is suitable for different elevator applications. Let's explore these types further to understand their characteristics and usage.
Side Sliding Doors
Side sliding doors are commonly used in modern elevator installations, especially in commercial buildings. These doors slide horizontally to open and close, allowing passengers to enter and exit the elevator cab. Side sliding doors are suitable for average elevator cab sizes and are often equipped with reliable door hangers, ensuring smooth and secure door operation. When combined with stainless steel door panels, side sliding doors provide both durability and a modern aesthetic appearance.
Center parting Doors
Center parting doors, also known as double-opening doors, are a popular choice for elevator cab designs, particularly in commercial applications. These doors open and close by parting in the center, creating a sleek and modern look for elevator cabs. Center parting doors are often used in modernization upgrades, replacing outdated elevator doors. The elevator door width for center parting doors adheres to industry standards, ensuring compatibility with commercial elevator shaft dimensions. With reliable performance and passenger safety in mind, center parting doors provide a practical and stylish solution for elevator systems.
Elevator Entrance and Door Frame Styles
Elevator entrance and door frame styles have a significant impact on the overall appearance and aesthetics of elevator cabs. Choosing the right material and design can enhance the visual appeal of an elevator, complementing the interior design of the building. Let's explore some popular elevator entrance and door frame styles, including glass elevator doors, stainless steel doors, and decorative elevator doors.
