yoyicassia@hotmail.com Hollow Metal Door
A hollow metal door is a durable steel door designed for commercial, industrial, institutional, and high-traffic applications. Manufactured from formed steel sheets with a reinforced hollow or insulated core, hollow metal doors provide a practical solution for interior and exterior openings.
Our hollow metal doors can be manufactured in different sizes, steel thicknesses, core constructions, surface finishes, hardware preparations, and frame configurations to meet project-specific requirements. They are suitable for offices, warehouses, factories, hospitals, schools, hotels, apartment buildings, utility rooms, and other commercial buildings.
What Is a Hollow Metal Door?
A hollow metal door is a steel door constructed from metal face sheets formed and reinforced around an internal core. Depending on the application, the door may use a honeycomb, polystyrene, polyurethane, mineral core, or other engineered core material.
The steel construction provides excellent resistance to impact, deformation, moisture, and everyday wear. Compared with many conventional wood doors, hollow metal doors are particularly suitable for demanding environments where durability and security are essential.
Hollow Metal Door Construction
The performance of a hollow metal door depends on its steel grade, thickness, internal reinforcement, core material, and manufacturing quality.
Steel Door Skin
The exterior face of the door is formed from steel sheet. Galvanized steel can provide enhanced corrosion resistance, while other steel grades and coatings can be selected according to project requirements.
Typical door skin thicknesses may include 18 gauge, 16 gauge, or 14 gauge steel, depending on the required strength and application.
Reinforced Internal Structure
Steel reinforcements are incorporated around hinges, locks, closers, panic hardware, and other hardware locations. This structure helps maintain door rigidity and supports reliable hardware installation.
Door Core
Different core options can provide different combinations of strength, insulation, sound reduction, and fire performance.
Common options include:
- Honeycomb core
- Polystyrene core
- Polyurethane core
- Mineral fiber core
- Steel-stiffened construction
