Iron Trapdoor is a metallic variant of the trapdoor that can only be opened using redstone mechanisms. It is craftable using iron ingots and can be found naturally in ancient cities. Unlike wooden trapdoors, it cannot be opened manually by players or mobs and requires a redstone signal to toggle.
Iron trapdoors must be mined with a pickaxe to drop as an item. They remain in place if their attachment block is removed. When powered, an Iron Trapdoor immediately opens, and when the signal is removed, it closes. Additionally, iron trapdoors are fire-resistant and do not burn in lava.
