Drop In Platform Systems

Compatible with all of our steel stairs, this platform design can best be described in a single word as flexible. Ideal for commercial egress stair applications, but just as well suited for the industrial stair and steel alternating tread stair. Without the size limitations of the single formed platforms, this is the model our designers go to when designing many of the more complicated stair systems and is the only platform that will work with our Model 03AA and 04AA stair models.

Drop-In Panel Options:  
  • ¼" Diamond Treadplate
  • Bar Grating
  • Grip Tread Material, similar to our Grip Treads on the Model 01AA/02AA stairs.
  • Concrete Pan – ready for site-poured concrete. Constructed of 1/4" flat plate.
  • Smooth Plate – 1/4" flat plate that you can apply your material (turf/carpeting/etc) to using adhesive. Lapeyre Stair does not provide the surface material or adhesive.
Possible Uses  
  • Exit Landings
  • Intermediate Landings
  • Switchback Landings
  • Work Platforms
  • *Crossover Systems (see special note about clearance, below)
Handrails: Handrails are 42” above the landing, and the configuration depends on your application. Handrails are provided on sides without stair mountings. The rails are the same 1½" OD tubing as the rail of the stairs. Aluminum clamps are provided to connect the stair handrail to the platform handrail.
*The framing on this platform is 8” high, the stair mounts to the top of the 8”. Therefore, in calculating the stair height for a crossover, you will need to add 8” to provide the clearance you will need under the crossover system.

Design Features

Drop In design Feature 1 Z-channel framing utilizes the same design as the stringers on our Model 01AA – 04AA stairs. The balusters of the guardrail slide through the frame and attach using provided spacers and bolts just as they do on the stairs.

There are very few size limitations. The modular design and drop-in sections allow for much larger platforms than our single piece formed platforms. Our customer service representatives will work with you and our designers to determine the best size and layout to meet your requirements.

Drop In design Feature 1 Panels can drop in either parallel or perpendicular with the framing, and attach to 3” C-Channel supports.

Fully integrated handrails, continuing from the stair onto the platform, are available upon request. Because most codes do not require this, the default design is to have the handrails end on the platforms, just let us know if you need continuous handrails on the platform.

Available with either a fully balustered design, or with filler panels. Drop In design Feature 1 Drop In design Feature 1
