Roof surfaces can be extremely dangerous places to work, but not if Kee® Step is installed. It provides a safe, anti-slip, level walking surface to access areas of the roof and to safely walk across it. Step sections are adjustable and can be used on sloped roofs too. Added to this, it also protects the roof sheet from foot traffic.

Frequently Asked Questions

    • What is a Step Over Platform?
      A step-over platform is a bridge-type structure designed to provide safe access over various obstacles such as parapet walls, pipework, ducting, plant equipment or any other obstruction. Crossover can be installed on roofs or on the ground and can be freestanding or fixed into the floor.
    • How do the Kee® Step Platform Ship?
      Standard step overs ship with cut tube, fittings, and tread assemblies palletized. Platforms can ship with the stair sets fully assembled for an additional fee. Most customers prefer to have the stairs shipped unassembled for easier roof loading.
    • What type of roofs are the Kee Step platforms suitable for?
      Our step over platforms are suitable for all types of roofs. We offer a wide range of standard step overs available off the shelf. These platforms are suitable for membrane, asphalt, PVC and concrete roofs. For other types of roofs, e.g. metal roofs, we can design and construct a bespoke step over platform. Please contact us to discuss details or fill in the form above.
    • How do I keep the base of the step over from damaging the roof?
      Step overs can be designed with rubber Kee Guard bases upon request. However, a simple slip-sheet below the base is typically sufficient enough to protect the roof membrane. We always recommend consulting your roofing company for proper slip sheets.
    • How do I assemble Kee® Step Platform?
      A full set of step-by-step assembly instructions are available in our download section below.
    • What is the tallest stair system I can build using Kee® Step Step Overs?
      We recommend a max height of 3m for the Kee® Step platforms. If you need a higher stair system please call one of our experts to help solve the problem.
    • How wide is the Kee® Step Platform?
      Standard width is 600mm but our design team can provide custom width step overs upon request.
    • I need 2 different stair heights, is this possible?
      Yes, just let our team know the height of each side of the step over and the length of the bridge required and we will provide you with the perfect solution.
