Vertical Access Cat Ladders
Vertical access cat ladders are a permanent, fixed means of access designed to allow safe movement between different levels of a structure where conventional staircases or inclined ladders are impractical.
They are widely used across industrial, commercial and infrastructure environments and are typically manufactured from galvanised steel to provide long-term durability in demanding conditions.
At Armco Barrier Supplies, our cat ladder systems are engineered to meet UK site requirements, integrating ladders, safety cages, intermediate rest platforms and handrails into a cohesive access solution suitable for both internal and external applications.
Our Vertical Access Cat Ladders are manufactured to your requirements.

Alternative Cat Ladder Names and Terminology
This type of access assembly is commonly referred to by several different names within the construction, engineering and facilities management sectors. These include:
- Cat ladders
- Fixed vertical ladders
- Vertical access ladders
- Caged ladders
- Safety cage ladders
- Industrial access ladders
- Maintenance access ladders
While terminology varies, all refer to a fixed vertical ladder system designed to provide controlled and repeatable access to plant, roofs, platforms or mezzanine levels.
Where Cat Ladders Are Used
Vertical cat ladders are used wherever safe, permanent access is required but floor space, headroom or layout constraints prevent the use of stairs. Typical applications include:
- Industrial plants and factories
- Warehouses and distribution centres
- Roof access for commercial buildings
- Access to mezzanine floors and gantries
- Plant rooms and rooftop HVAC equipment
- Silos, tanks and process machinery
- Power stations, utilities and infrastructure assets
In many cases, cat ladders form part of a wider access strategy, connecting multiple intermediate landings or platforms, as shown in the attached example where rest platforms and guardrails are incorporated at regular vertical intervals.

Why Cat Ladders Are Used
Cat ladders offer several practical and safety-related advantages:
- Space efficiency – They require minimal horizontal footprint compared with staircases.
- Permanent access – Fixed installation ensures consistent access without reliance on portable equipment.
- Improved safety – When correctly specified, safety cages, rest platforms and handrails significantly reduce fall risk.
- Durability – Galvanised steel construction provides excellent resistance to corrosion and mechanical damage.
- Compliance support – Designed to align with UK standards and workplace access requirements when correctly specified and installed.
For facilities with regular maintenance regimes, cat ladders provide a predictable and controlled access route that can be incorporated into site risk assessments and method statements.
Key Considerations When Installing a Cat Ladder
Installing a vertical access cat ladder requires careful planning to ensure safety, compliance and long-term usability. Important factors include:
- Vertical Height and Rest Platforms: The total climb height determines whether intermediate rest platforms are required. For taller installations, platforms provide a safe point to stop, rest and transition between ladder sections.
- Safety Cages and Fall Protection: For vertical ladders exceeding certain heights, a safety cage or alternative fall arrest system is typically required. The cage must be correctly sized, positioned and terminated at safe access points.
- Fixing Structure and Load Paths: The supporting structure must be capable of taking ladder loads, including user weight, dynamic forces and wind loading for external installations. Fixings should be designed to suit concrete, steel or masonry substrates as appropriate.
- Access and Egress Points: The transition on and off the ladder is a critical safety detail. Handholds, landing gates, guardrails and toe protection should be provided at platforms and upper access points.
- Environmental Conditions: External ladders may be exposed to weather, chemicals or coastal environments. Material selection, galvanising specification and detailing should reflect the site conditions.
What to Consider When Purchasing a Cat Ladder
When specifying or purchasing a cat ladder system, the following points should be reviewed carefully:
- Compliance with UK standards and guidance relevant to fixed ladders and work at height
- Overall ladder height and configuration, including number of sections and platforms
- Safety features, such as cages, handrails, self-closing gates and kick plates
- Material and finish, typically hot-dip galvanised steel for longevity
- Integration with existing structures, platforms or steelwork
- Future maintenance access needs, not just initial installation requirements
A well-designed cat ladder should not be treated as a standalone product but as part of a complete access solution tailored to the site.
