Electropolished step stairs and work platforms, with and without safety rails, are ideal for cleanroom maintenance tasks

Terra's steel step stairs are compliant with OSHA's Part 1926-1053 safety requirements for Type IA Ladders (300 lb. duty rating). They are ideal for performing maintenance tasks (like replacing filters) in a clean room environment. 

Their spring-loaded casters, made entirely of stainless steel, eliminate contamination sources and ensure that they won't roll during use. Nylon leveling feet can be adjusted to compensate for uneven floors.

Safety rails (optional on smaller models) further enhance personnel safety. Standard models include perforations; other designs are available on a custom basis.

  FEATURES & BENEFITS | BioSafe Step Stairs
Alt Text
Clean and sturdy all-stainless-steel construction,including internal spring
Alt Text
Electropolishing creates an ultra-smooth surface free of burrs and crevices that can trap contaminants

Beveled Exit Slots
Perforations on horizontal surfaces support laminar air flow and minimize turbulence

Compare the continuous-seam weld BioSafe design (left side of each photo) with hard-to-clean cracks of a non-continuous weld model (right side) All-stainless-steel, non-shedding casters, and non-contaminating nylon leveling feet

Why is Electropolishing Critical?
Removes iron and other surface impurities that cause corrosion
Draws chromium and nickel to form a hard, protective finish
Removes irregularities (pits and burs) for an ultra-smooth surface that's easy to clean
