How do you design a strong and safe stairway?

As an AI language model, I can provide you these general guidelines to design a strong and safe stairway:

1. Materials: Choose high-quality and sturdy materials for constructing the stairway. Common choices are wood, metal, and concrete.

2. Width and Depth: The standard width for a stairway is 36 inches. The depth of the treads should be at least 10 inches to provide enough space for your foot.

3. Height: The height of each riser should be between 7 to 8 inches.

4. Treads: Stair treads should have a textured surface or a non-slip tread to prevent slips and falls.

5. Handrails: Install handrails on both sides of the staircase to provide support while climbing up and down. The handrail should be placed at a height of 34 to 38 inches.

6. Lighting: Install proper lighting on the staircase to ensure good visibility.

7. Clearances: Provide sufficient clearance on each side of the stairs to prevent accidents.

8. Code Compliance: Always follow local building codes and regulations for property safety and accessibility.

By ensuring you meet these guidelines, you will be improving the safety of people who use the stairway, whether in a residential or commercial setting.
