BioSafe® Step Stairs and Work Platforms
Non-folding, continuous seam-welded models for aseptic environments!

step stools and step ladder
Electropolished step stairs and work platforms,
with and without safety rails,
are ideal for cleanroom maintenance tasks
  • A step up in cleanliness and safety! These postable stairs meet OSHA safety and load capacity standards
  • All-stainless steel spring-loaded casters retract when weight is applied
  • 0.75" (19 mm)-diameter perforations accommodate vertical laminar air-flow and minimize particle accumulation
  • BioSafe models feature continuous-seam welds to create highly cleanable surfaces free of cracks that harbor germs
  • Custom sizes and configurations available—call with your specifications!

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.

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
