Hollow metal doors are a type of door constructed primarily from metal, typically steel or aluminum. Unlike solid metal doors, which are made entirely of metal, hollow metal doors have a hollow core filled with insulation material, such as polystyrene or honeycomb cardboard. This design makes them lighter in weight while still offering durability and strength.

Here's a detailed description:

Material: Hollow metal doors are typically made from steel or aluminum, providing exceptional strength and resistance to impact and damage.

Construction: The doors consist of metal sheets formed into panels, with a hollow space between them. This hollow core is filled with insulation material, which enhances thermal and sound insulation properties.

Versatility: These doors are available in various sizes, styles, and configurations to suit different architectural and functional requirements. They can be customized with features such as windows, louvers, or additional reinforcement for security purposes.

Durability: Hollow metal doors are known for their robustness and longevity. They are resistant to warping, cracking, and corrosion, making them suitable for use in various environments, including high-traffic areas and harsh weather conditions.

Security: Due to their sturdy construction, hollow metal doors offer excellent security against forced entry and vandalism. They can be further reinforced with heavy-duty locks, hinges, and other security hardware.

Fire Resistance: Many hollow metal doors are fire-rated, meaning they can withstand fire for a specified period, providing crucial protection in buildings where fire safety is a concern.

Maintenance: These doors require minimal maintenance, typically only needing occasional cleaning and inspection of hardware components to ensure proper functioning.

Applications: Hollow metal doors are commonly used in commercial, industrial, and institutional buildings, including offices, schools, hospitals, and warehouses. They are also suitable for exterior applications, such as entrance doors and fire exits.

In summary, hollow metal doors combine strength, durability, and versatility, making them a popular choice for a wide range of applications where security, reliability, and performance are essential
