How do you build metal staircase?

Building a metal staircase involves several key steps: first, design the staircase layout, including dimensions and materials. Next, cut the metal components, such as the stringers, treads, and risers, using appropriate tools like a metal saw or plasma cutter. Assemble the parts by welding or bolting them together, ensuring they are level and secure. Finally, finish the staircase with a protective coating to prevent rust and enhance durability.
