A hollow metal door (also called steel door or commercial hollow metal door) is made from cold-rolled or galvanized steel sheets formed into two face panels with a hollow core (often reinforced with honeycomb, polystyrene, polyurethane, or steel stiffeners). It's the industry standard for commercial, institutional, and industrial applications.

Q:Where are hollow metal doors typically used?

Schools, hospitals, offices, warehouses, hotels, factories, stairwells, corridors, and high-traffic/exterior openings requiring durability, security, or fire protection.

Q:What is a reversible hollow metal door leaf?

A door leaf that can be flipped on-site to change from left-hand to right-hand swing (or vice versa), no need to order specific handing.

Q:Why choose reversible hollow metal doors?
