steel door
Heavy secure entry
A steel door is a door made primarily of steel, chosen for security, fire resistance, or durability.
Steel doors are standard in commercial buildings, industrial facilities, and exterior residential entrances where strength matters more than aesthetics: The warehouse had a heavy steel door with three deadbolts.
They resist forced entry better than wood or fiberglass alternatives.
