Custom Stair Tower Design: Staircase Tower Modules for Construction & More
Stair Towers
Custom Stair Tower Design Benefits
Modular, permanent, code-compliant, stair towers are designed to save time and money over custom-designed stair towers.
Designed in modular units with a choice of standard industrial stairs or alternating tread stairs. Each unit is assembled and then installed by stacking and bolting together at the base plates for easy alignment. No welding is required for assembly or installation.
Our stair towers can be completely independent or integrated into existing structures.
No post-manufacturing welding is necessary.Â
Our knock-down design ships flat, arrives ready to assemble, and requires no welding or expensive equipment for installation.
Stair towers can be designed with space-saving alternating tread stair or standard industrial stairs.
Stair Tower Solutions for Any Size
There are no out of the box solutions when it comes to designing safe, compliant access. Our designers, engineers, and production teams are standing by build the exact system you require.

About our Stair Towers
Why Lapeyre Stair for your Stair Tower?
We’ve been working with commercial contractors and architects to design and produce pre-fabricated, free standing stair towers and secure rooftop and structure access for more than 40 years. Our versatile stair tower structures are designed to support applications exceeding 25 feet in height.
Our stair towers save valuable time and reduce costs and are available with standard industrial stairs or space-saving alternating tread stairs.
Frequently Asked Questions about Stair Towers
Why is a stair tower system preferred?
A stair tower system is generally preferred over a traditional ladder due to its increased safety and worker efficiency. Workers go up and down stair towers in the direction of travel, which reduces the risk of slips and falls and is generally faster than climbing up or down a ladder. With their hands free, workers can also carry any needed tools and equipment while climbing the stair tower. Stair towers also provide platforms between the various staircases allowing workers the opportunity to stop or rest at any point during the climb.
What is the safe working height of a stair tower?
The maximum height of a free-standing stair tower is 50’. However, attached stair towers are safe at larger heights.
What is the difference between scaffolding and a stair tower?
Scaffolding is a temporary structure on the outside of a building to enable exterior access while repairing or cleaning a building. On the other hand, a stair tower is a permanent structure allowing access to rooftops and equipment. Scaffolding generally has a smaller footprint than a stair tower and may be assembled more quickly.
Scaffolding is generally not used to reach heights as tall as stair towers can. With a bigger footprint and the ability to climb or descend in the direction of travel, stair towers are a safer alternative to scaffolding.

Stair Tower Materials: Powder-Coated or Galvanized?
In selecting between powder-coated carbon steel and galvanized carbon steel for exterior stair towers, both materials have their strengths.Â
Galvanized carbon steel offers superior durability and corrosion resistance, particularly in harsh environments, with minimal maintenance requirements.Â
Powder-coated carbon steel, excels in aesthetics, is offered in a variety of RAL colors, and is more environmentally friendly in terms of production.Â
Ultimately, the choice between the two materials depends on the specific requirements of the project, including budget, desired appearance, and environmental conditions.
