Steel Doors are blocks that can be crafted and placed and are used to block an entry. They take a space of 1×2×1 blocks. They can only be opened and closed by the same player who placed it. Also, a steel door can even survive explosions like those from TNT. Right-click to open the door, and right-click to close it again. If there is not enough space to place a door (1×2×1), the door will be lost. There are also double doors, if placing in correct order.
