A Ladder Stairway is characterized by its steep slope and alternating tread configuration, which allows for vertical access in a limited footprint. It involves a series of alternating treads that are inclined at a steep angle. The alternating tread allows for a steeper slope than a conventional staircase while still providing a safe and stable means of ascent and descent. Attributes:• Provide efficient vertical access between levels• Provide a safe and stable while ascent and descent Applications:A Ladder Stairway provides vertical access in spaces where a traditional staircase would be impractical due to space constraints, It allows individuals to safely ascend and descend between different levels within the structure.
