Roof Access Ladders

Due to modern designs most buildings have varying roof levels. Permanently fixed ladders allow workers to safely access these levels with ease.

Use a roof access ladder with a return when traversing walls, obstacles, or tall parapets.

Custom ladders are built for each installation location.

Our industrial ladders have a 20" rung width but can be custom sized anywhere between 16" and 24" as the project requires.

Rungs are attached with heavy duty, plug welded assembly.

Add on rung covers to increase tread in wet, oily, or icy conditions.

Ladder Cages

A ladder cage is required when the length of climb is 20 ft and greater above floor level.

Standard cage is 27" inside, but can be designed up to 30".

Specialty Ladders

Angled Ladder

Similar to a ships ladder, it is designed to be used when not enough space exists for a conventional staircase and a standard ladder can't be used due to worker's requirement to carry equipment up it.

  • Can be combined with a return ladder if required.
  • Can be installed with or without handrail.
  • Pre-formed ladder treads are available.
  • Standard finish is hot dip galvanized. Other finishes such as powder coating and paint are available.

Ships Ladder

Retractable Ladders

Retractable ladders are used to limit and prevent access for security purposes. Also for use when the ladder needs to be kept out of the way.

  • Aluminum or steel fixed ladder portion
  • Aluminum sliding section
  • For use on applications less than 24' in vertical height from the ground.
  • Smooth sliding operation.
  • If no wall support available, ground support may be required.
