These are steeper than stairs but less steep than vertical ladders.

The standard dictates the relationship between the rise (height of the step) and the going (depth of the step). This is often calculated using the "step formula" to ensure a natural walking rhythm.

    Let’s walk through a typical scenario: You need to provide access to a machine control platform at 3000 mm height.

    Step 1 – Choose stair angle. You select 38° (optimal for industrial environments).

    Step 2 – Calculate flight length. Using standard step rise of 200 mm: 3000 mm / 200 mm = 15 steps. Number of risers = 15. Number of treads = 14 (one less for top floor landing). These are steeper than stairs but less steep

    Step 3 – Check tread depth. For 38°, the tread depth (going) should be approximately 250–300 mm. Total horizontal run = 14 x 250 mm = 3500 mm.

    Step 4 – Add guardrails. Both sides of the stair require handrails. The open side of the landing requires a full guardrail (top rail at 1100 mm, intermediate rail, toe plate 100 mm).

    Step 5 – Document compliance. In your technical file (for CE marking), you reference din en iso 14122-3 pdf and cross-check each measurement against the standard’s tables. Stepladders / steps

    Current Designation: DIN EN ISO 14122-3:2016-10 (or the most recent 2018/2021 amendments depending on jurisdiction).

    The standard defines specific angles for different types of access:

    Why this matters: Angles steeper than 45° require different step designs and handrail positions.
