A system that gives the user benefits of a durable plastic encapsulated ladder without the need to specify an exact length or fit on-site. In addition, a single specification can be used for all depths of access.

Product Specifications

BS 13101 Plastic Encapsulated Steps

WIS 4-33-01: 1990 Polypropylene Encapsulated Steps


  • Concrete manholes and inspection chambers
  • Renovation of existing structures


The plastic encapsulated ladder has a bright yellow coating and is made from high impact virgin polypropylene copolymer plastic. If the ladder is to be subject to prolonged exposure to daylight then black or UV stabilised material should be specified. It is reinforced with structural steel.


Pull out load: 7.5kN minimum when fitted in accordance with manufacturer’s instructions

Deflection under load:  5mm maximum at 2.5kN

Permanent Set: 0mm at 2.5kN

Impact: 20kg weight from 1 metre, no cracking

Chemical Resistance: At least pH2 to 12

The integrity of plastic: 2M ohm at 500 volts DC

The thickness of plastic: 3mm minimum

Minimum cross-section: 25mm diameter

Product Benefits:

  • Excellent corrosion resistance
  • Visibility
  • No sharp edges
  • Eliminates need to specify the exact length or fit on-site.
  • Steel reinforcement gives predictable deflection under load without causing brittle failure
