What are the different types of aluminum profiles used for staircases?

Aluminum profiles for staircases are diverse and serve different functions. Common types include: 1. Handrail profiles, which provide support and safety. 2. Stringer profiles, forming the backbone of the staircase. 3. Tread profiles, which are the horizontal surfaces on which one steps. 4. Riser profiles, covering the vertical space between steps. 5. Baluster profiles, used as vertical supports between handrails and treads. 6. Connector profiles, for joining different parts of the staircase. Each type is designed to withstand specific loads and is chosen based on the staircase's design, weight capacity, and aesthetic requirements.
