Crossover Stairs

Industrial Crossover stairs, bridges, rooftop and work platforms that are OSHA compliant and provide custom-built safe access for daily operations, and routine maintenance

OSHA Industrial Crossover Stairs & Roof Crossover Platforms

Standard industrial and alternating tread crossover stairs, pre-engineered, custom designs that move people safely.

Safety First. Always Compliant.

01
Space Saving Designs

Alternating tread crossover stairs require a smaller overall footprint than standard stairs because of their steeper slope of either 56 or 68 degrees

02
Material Handling Expertise

Lapeyre Stair has crafted custom access and integrated systems since 1981.

03
Fast Lead Times

Our lead times outpace industry standards and are guarenteed.

04
Customized to Your Needs

Our designs are built to precise dimensions, down to the 1/8th of an inch.

05
Integrator Support

Our designers and engineers work hand in hand with integrators across the counrty.

06
Heavy Duty Materials

Our crossover stair systems are available in heavy-gauge, powder coated and galvanized carbon steel, stainless steel, and aluminum.

Alternating Tread Crossover Stair

Standard? Space-saving? Choosing the Right Crossover Stair System.

Are you battling unimaginable layouts and obstacles? Put our team of engineers and designers to work solving your crossover headaches. We’ll work with you to design compliant solutions to your exact needs, down to a fraction of an inch.

Industrial Crossover Stairs

More space? Choose a crossover with industrial access stairs.

Choose crossovers with bolted access stairs for applications without space restrictions. They have standard stairs that require more space to install than alternating tread stairs but they are also the most comfortable to use.

Alternating Tread Crossover Stairs

Less space? Choose a crossover with alternating tread stairs.

For applications where space is limited, choose crossovers with alternating tread stairs. 68° alternating tread stairs require the least amount of space but the steeper angle is less comfortable to use. The less steep angle of 56° alternating tread stairs is more comfortable to use while also requiring less space.

Addition Products for Industrial Crossover Stairs

Crossover Stair Cross Bracing Kit

Taller crossover bridges with alternating tread stairs may require bracing to prevent swaying. The bracing kit for these systems includes stainless steel brackets and hardware for the upper and lower connections plus custom tubing in the same material and finish as your crossover system.

We need the following information to calculate bracing specifications. Contact us for assistance with determining the optimal spread and brace angles for your system.

✔ Dimensions of obstacles surrounding the system
✔ Optimal spread angle (0° to 20° for 56° stairs; 0° to 10° for 68° stairs)
✔ Optimal brace angle (20° to 30° from the vertical plane)

The cost of the bracing kit is included in the list price for crossovers with alternating tread stairs. Subtract $328.22 from the list price if you will provide your own bracing for the system.
