Specify the Best – Aluminum Fixed Caged Ladder – Part II

We regularly receive questions asking what material of construction is best when specifying ladders.  As noted in our Part I to Specifying the Best we have provided tips and information on specifying right material for your application.

In specifying an aluminum or carbon steel ladder design, always specify a fixed ladder design that incorporates recognized codes/standards and high quality component features.  This includes:

  • Review supplier’s ladder specification – should meet OSHA and ANSI requirements.
  • Always review the design of the “ladder component assemblies.” If a supplier doesn’t outline their component design or if they tell you it is proprietary, move on to another supplier.
  • Additionally, specify your preferred materials of construction (aluminum, carbon steel, stainless steel or other)
  • If carbon steel is specified, outline your surface prep requirements, primer spec, topcoat spec and color.
  • Be specific in defining unique requirements.  For example, ladder cage, number of platforms, lock out door, guardrail extensions at the top, standoff bracket distance, safety gates, safety climb device, etc.
  • Lastly, specify any special code or engineering requirements

High Quality Fixed Caged Ladders

All high quality fixed ladder designs can be supported with engineering calculations and a PE stamp from any state in the U.S., at additional cost.  Additionally, as a standard, a custom drawing for each application should be provided by the ladder manufacturer.

High quality ladder designs don’t necessarily cost more than low quality ladder products.  However, you must specify your requirements or you will likely be disappointed with the product received.

In comparison, an extruded ladder rung offered by Ascend Fab is twice the diameter of a competitor rung design and twice the thickness.  Which rung assembly would you prefer?  As previously noted, any quality ladder supplier should provide their component design descriptions for review.  Below,  we have provided Ascend Fab Component Descriptions for fixed ladders that is listed online:
