Steel Trapdoors are blocks that can be crafted, placed, opened and closed by the player. They can only be opened and closed by the same player who placed it. Also, a steel trapdoor can even survive explosions like those from TNT. Unlike normal doors, steel trapdoors are placed on the floor.
Use to open the steel trapdoor, and use again to close it. An opened steel trapdoor can be climbed like a ladder.
