      With modern aesthetics, unbeatable strength, and full compliance, this staircase is a premium upgrade over standard outdoor steps.

      Are platforms included with the stairs?

      Unfortunately, not. This is because accommodating various sizes of platforms would require stocking a significant range. We suggest consulting a local builder or fabricator if a platform is necessary.

      Can it be painted or powder coated?
