Fire Escape Staircases

Exterior Aluminum Stairs


Aluminum is non-combustible, and the metal would have to be upwards of 1220° Fahrenheit to melt which is far past a usable temperature anyway.


Our fire exit stairs are 100% mill-finish aluminum with stainless steel fasteners, so it will never rust and remains structurally sound even in coastal locations.


We design all of our exterior fire stairs to meet whichever code is required for the project whether it needs to meet ADA, OSHA, IBC, ABA, or local building codes.

The International Building Code (IBC) is slowly eliminating the use of traditional style fire escapes because they are not very safe, and in fact, new fire escape routes cannot include ladders. New construction will have to incorporate interior means of egress or exterior fire escape staircases complete with handrails and slip-resistant step tread material.

Fire escape stairs 

  • 100% structural aluminum – thickness and type depends on the height and layout
  • Typically designed to be freestanding – we design a frame out of structural I-Beams or square tube support columns
  • Custom design to fit within your footprint
  • We can comply with ADA, IBC, OSHA, or any other code that is required
  • Prefabricated so that no on-site welding is required
  • We can install anything under 50′ tall, but any fire exit stair tower taller than 50′ will require a general contractor to install.

Design options

  • Tread material options are: solid extruded decking, grip strut decking, bar grate decking
  • Guardrails with handrails or just guardrails
  • Powder-coating color options
  • Gate options to secure access to the stairs
  • Platform sizes

Steel vs. Aluminum Fire Exit Stairs

When choosing what type of fire escape staircase to construct on the building exterior, it is important to consider the material. Aluminum is the best material for fire escape stairs because it non-combustible and has a high melting point. Galvanized steel is an alternative to aluminum, but it is more costly to ship and much heavier and harder to install. Galvanized steel will also require maintenance as the galvanizing layer corrodes over time whereas aluminum requires zero maintenance and is highly-corrosion resistant.

We couldn’t be more pleased

Very pleased with this product. It looks great and the material will hold up well to the elements. We couldn’t be more pleased with how this project turned out. Everyone at your company was great to work with and very helpful through the entire process.
