What Is A Hollow Metal Door?

A hollow metal door is a type of door commonly used in commercial and industrial buildings. As the name suggests, these doors are made from a sheet of metal that has been formed into a hollow core. The core is typically filled with a honeycomb or polystyrene insulation, which helps to improve the door's energy efficiency and acoustic properties. The metal used to make hollow metal doors is usually steel, which is a strong and durable material that can withstand heavy use and abuse. Additionally, hollow metal doors are typically fire-rated, which means they have been tested and certified to meet specific fire safety standards. These doors can come in various sizes and styles and are a popular choice for commercial and industrial applications where security, durability, and fire protection are essential.
