Industrial crossover stairs and platforms

Safely overcome virtually any obstacle with OSHA-compliant crossover systems.

OSHA compliance

All of our crossover stair systems are designed to comply with the current OSHA regulations for general industry.

The regulations governing our industrial crossover stairs are covered in Standard 1910, Subpart D, Walking-Working Surfaces:

1910.22 - General requirements

1910.25 - Stairways

1910.28 - Duty to have fall protection

1910.29 - Fall protection systems

Types of industrial crossovers stairs and platforms

Crossovers, also called crossover bridges, are available with a choice of bolted access stairs or alternating tread stairs. Crossovers with bolted access stairs are available with steel platforms and stairs with a choice of options. Crossovers with alternating tread stairs are available with 68° stairs (with either steel or aluminum stairs and steel platforms) or 56° (with steel stairs and platforms) with a choice of options.

How to choose the best type of crossover stair for your application

More space? Choose a crossover with bolted 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.

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.

What does OSHA say about crossovers with alternating tread stairs?

OSHA classifies alternating tread stairs (alternating tread devices) as non-standard stairs and states they are acceptable to use in applications where it is not feasible to use standard stairs.

Crossovers with alternating tread stairs

Stair SLOPE of either 56° or 68° from the horizontal §1910.25(f)

TREADS are at least 8½ inches deep with open risers and at least 7 inches wide at the leading edge §1910.25(f)(3), §1910.25(f)(4), §1910.25(f)(5)

FALL PROTECTION system with less than 19 inches between horizontal mid-rails OSHA §1910.29(b)(2)

The overall dimensions of height, width and length must fit within the amount of space that is available to install the crossover system. If you have enough room to install a crossover system with standard stairs, that is the OSHA-preferred solution.

The platform length and stair height are determined by the dimensions of the obstacle. These measurements are used to calculate the overall dimensions of the crossover system.

Standard options for crossovers with alternating tread stairs

Carbon steel with safety yellow, iron gray, or gray primer powder coat finish
56° or 68° degree alternating tread stairs
Carbon steel with safety yellow, iron gray, or gray primer powder coat finish
Diamond plate platform decking
OSHA-compliant 42" high guardrails constructed of 1½ inch round tubing

Back pans for stairs
Safety gates
Additional stair heights and platform sizes
Varying stair heights

Crossover bracing kit

Crossovers with alternating tread stairs 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 $303.91 from the list price if you will provide your own bracing for the system.

Optional accessories for crossovers with alternating tread stairs

Safety gates

Safety gates provide additional security at the top of alternating tread stairs. They attach to the platform rails with reversible hinges and provide a 180° gate swing.

$319.10/gate: Carbon steel with standard powder coat colors
$329.75/gate: Carbon steel with hot-dip galvanized finish
$600.20/gate: Grade 304 stainless steel with mill finish

Backpans

Minimize the risk of damage to workers and equipment beneath your crossover system by adding backpans to the alternating tread stairs. Backpans bolt under the stairs to form a solid barrier behind the treads that spans the height of the stair and provides protection from falling objects.

Pricing for backpans is based on the stair height.

STAIR RISERS with a uniform height of no more than 9.5 inches and a uniform depth of at least 9.5 inches §1910.25(b)(3), §1910.25(c)(2), §1910.25(c)(3)

FALL PROTECTION system with less than 19 inches between horizontal mid-rails and vertical balusters 1910.29(b)(2)(i), §1910.29(b)(2)(iii), §1910.29(b)(2)(iv)

The overall dimensions of height, width and length must fit within the amount of space that is available to install the crossover system. Alternating tread stair crossover systems are OSHA-compliant if you do not have enough space to install a system with standard stairs.

The platform length and stair height are determined by the dimensions of the obstacle. These measurements are used to calculate the overall dimensions of the crossover system.

Crossovers with alternating tread stairs

Stair SLOPE of either 56° or 68° from the horizontal §1910.25(f)

TREADS are at least 8½ inches deep with open risers and at least 7 inches wide at the leading edge §1910.25(f)(3), §1910.25(f)(4), §1910.25(f)(5)

FALL PROTECTION system with less than 19 inches between horizontal mid-rails OSHA §1910.29(b)(2)

The overall dimensions of height, width and length must fit within the amount of space that is available to install the crossover system. If you have enough room to install a crossover system with standard stairs, that is the OSHA-preferred solution.

The platform length and stair height are determined by the dimensions of the obstacle. These measurements are used to calculate the overall dimensions of the crossover system.

Standard options for crossovers with alternating tread stairs

  • Carbon steel with safety yellow, iron gray, or gray primer powder coat finish
  • 56° or 68° degree alternating tread stairs
  • Carbon steel with safety yellow, iron gray, or gray primer powder coat finish
  • Diamond plate platform decking
  • OSHA-compliant 42" high guardrails constructed of 1½ inch round tubing
  • Crossover bracing kit
  • All assembly hardware

Additional options are also available

  • Carbon steel with custom powder coat colors
  • Carbon steel with hot-dip galvanized finish
  • Grade 304 stainless steel
  • 68° aluminum alternating tread stairs
  • Back pans for stairs
  • Safety gates
  • Additional stair heights and platform sizes
  • Varying stair heights
  • Additional platform decking and configurations

Crossover bracing kit

Crossovers with alternating tread stairs 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 $303.91 from the list price if you will provide your own bracing for the system.

Optional accessories for crossovers with alternating tread stairs

Safety gates

Safety gates provide additional security at the top of alternating tread stairs. They attach to the platform rails with reversible hinges and provide a 180° gate swing.

$319.10/gate: Carbon steel with standard powder coat colors
$329.75/gate: Carbon steel with hot-dip galvanized finish
$600.20/gate: Grade 304 stainless steel with mill finish

Backpans

Minimize the risk of damage to workers and equipment beneath your crossover system by adding backpans to the alternating tread stairs. Backpans bolt under the stairs to form a solid barrier behind the treads that spans the height of the stair and provides protection from falling objects.

Pricing for backpans is based on the stair height.
