Doors are an essential component of buildings and structures. They are designed to provide entry, exit, and access control to different areas. Doors come in various types, styles, and materials, catering to different functional and aesthetic needs.

Some common types of doors include:

• Single and double doors: These are the most basic types, consisting of a single panel or two panels hinged on one side.
• Sliding doors: These doors slide horizontally along a track, making them space-efficient and ideal for areas with limited space.
• Folding doors: Also known as bi-fold doors, they fold and stack to one side when opened, creating a wide opening.
• French doors: These are typically made up of two hinged panels that swing open, providing a wide entryway and an elegant aesthetic.
• Revolving doors: Often found in commercial buildings, revolving doors consist of multiple panels that rotate around a central axis, allowing smooth traffic flow.
• Automatic doors: These doors use sensors or buttons to open and close automatically, providing convenience and accessibility for people with mobility challenges.
