Kee Step® Step Over Platforms

Kee Step® Step Over Platforms are modular access systems designed to allow workers to safely cross rooftop obstacles.

Rather than requiring workers to climb over pipework, cables or plant, the platform provides a designated route up, over and down the other side of the obstruction.

Kee Step® systems can provide safe access over:

• Pipework
• Cable trays
• Ducting
• Conduits
• HVAC services
• Rooftop plant
• Low-level walls and suitable obstructions
• Changes in roof level

The modular design means each roof step over can be configured around the dimensions of the obstacle and the available space.

Kee Step® platforms are particularly useful on commercial and industrial buildings where regular inspections and maintenance require workers to follow consistent routes across busy rooftops.

Kee Step® combines modular construction with purpose-designed access components to create a crossover tailored to the obstacle.

Modular Construction - The modular system allows step overs to be configured to suit different widths, heights and rooftop layouts.

This makes Kee Step® suitable for both straightforward obstacles and more complex rooftop access requirements.

Anti-Slip Treads -  Steps and walking surfaces provide a secure, anti-slip route across the obstacle.

This is particularly important on exposed rooftops where surfaces can become wet due to rain, frost and changing weather conditions.

Integrated Handrails -  Where required by the system configuration, guardrails provide additional protection while workers ascend, cross and descend the platform.

This helps create a clearly defined access route rather than leaving users exposed while crossing the obstacle.

Freestanding or Fixed Installation -  Kee Step® can be configured using different installation methods depending on the roof and application.

Freestanding arrangements can use weighted bases where appropriate, helping avoid unnecessary penetrations of certain roof coverings.

Other applications may use suitable base plates or fixing arrangements according to the roof construction and system specification.

Bespoke Configurations -  Not every rooftop obstacle fits a standard size.

Kee Step® can therefore be configured to accommodate different obstacle dimensions, access directions and available roof space.

One of the main advantages of Kee Step® is its versatility.

Pipework - Large pipes and groups of services can block otherwise straightforward maintenance routes.

A Kee Step® pipework crossover allows workers to pass safely over them without stepping directly onto the services.

Cable Trays - Cable management systems can create low-level trip hazards across roof access routes.

Mini step overs can provide an effective solution where only limited clearance is required.

HVAC Systems  - Air conditioning and ventilation infrastructure can make rooftop navigation difficult. Step over platforms can be incorporated into maintenance routes around HVAC installations.

Ducting and Conduits - Wide ductwork and electrical conduits can be crossed safely using a platform designed around their dimensions.

Rooftop Plant - Where plant equipment obstructs the most appropriate access route, a bespoke crossover can help maintain safe movement around the roof.

Changes in Roof Level - Kee Step® can also help workers negotiate appropriate changes in level where a dedicated access solution is required.

Low-Level Rooftop Obstacles - Not every obstruction requires a large platform. Kee Step® Mini configurations are designed for smaller obstacles where a compact solution is more appropriate.

Kee Step® can be configured for a variety of commercial and industrial roofing systems. The correct installation method depends on the roof construction, condition and project requirements.

Membrane Roofs - Freestanding configurations can be suitable for membrane roofs where avoiding unnecessary roof penetrations is particularly important.

Metal Roofs - Appropriate fixed or supported configurations can provide access across metal roof systems.

Standing Seam Roofs - Step overs can be specified for suitable standing seam applications using installation methods appropriate to the roofing system.

Concrete Roofs - Concrete rooftops can accommodate fixed access solutions where appropriate to the structural design and site requirements.

Asphalt Roofs - Kee Step® can also be configured for suitable asphalt roof applications following an assessment of the roof and proposed access route.

Flat Roofs - Commercial flat roofs are among the most common applications for rooftop crossover platforms because plant and building services frequently obstruct maintenance routes.

A professional roof survey should always determine the most appropriate configuration and installation method rather than assuming a single system is suitable for every roof.

Different rooftop obstacles require different crossover configurations.

Standard Kee Step® Step Over Platforms - Standard Kee Step® platforms are designed for larger obstacles and are available in several clearance heights.

Typical standard options include approximately:

• 600mm clearance
• 800mm clearance
• 1,000mm clearance
• 1,200mm clearance
• 1,400mm clearance

Standard configurations can incorporate a landing area and double handrails to create a clearly defined route over larger rooftop obstacles.

Where a standard configuration does not meet the site's requirements, bespoke designs can be developed.

Kee Step® Mini Step Overs - Kee Step® Mini is designed for smaller obstacles such as low-level pipework and cable trays.

Typical clearance options include approximately:

• 200mm
• 400mm

Different tread configurations can be selected according to the required access.

These compact platforms provide an alternative to stepping directly over low-level services while taking up less rooftop space than a full crossover platform.

Safer Access Over Rooftop Obstacles - Purpose-designed steps and platforms remove the need to climb directly over services.

Anti-Slip Walking Surface - Treads provide a secure surface designed for rooftop access.

Clearly Defined Maintenance Routes - Kee Step® helps establish consistent routes between access points and rooftop equipment.

Modular Construction - Individual components can be configured around the requirements of the building.

Bespoke Options - Platforms can accommodate unusual obstacles and more complex access requirements.

Suitable for Retrofit Projects - Kee Step® can be incorporated into existing rooftops as part of an access improvement programme.

Freestanding Options - Where appropriate, freestanding systems can reduce the requirement for penetrative fixing into the roof.

Durable Construction - Components are designed for long-term use in exposed commercial and industrial environments.

Low Maintenance - Routine inspection and maintenance help provide dependable long-term performance.

Compatible with Other Roof Safety Systems - Kee Step® can form part of a wider rooftop safety strategy incorporating walkways, edge protection and fall protection systems.

Working at height equipment should be properly specified for its intended application and installed by competent professionals.

Work at Height Regulations 2005

The Work at Height Regulations require duty holders to properly plan work at height and assess the associated risks.

Where work at height cannot be avoided, measures should be taken to prevent falls so far as reasonably practicable.

Providing purpose-designed access over rooftop obstacles can form part of this wider approach to risk reduction.

BS EN ISO 14122

The BS EN ISO 14122 series covers permanent means of access to machinery and includes requirements relevant to working platforms, walkways, stairs and guardrails.

Kee Step® configurations can be designed with the relevant requirements of BS EN ISO 14122-2 and BS EN ISO 14122-3 in mind.

The exact compliance requirements should always be assessed for the individual installation.

EN 516

Relevant Kee Step® Mini step modules are designed and tested in accordance with applicable EN 516 Class 1-C requirements for roof access products.

Step over platforms often work most effectively as one part of a complete rooftop access strategy.

Kee Walk® Rooftop Walkway Systems - Kee Walk® provides a clearly defined walking route across the roof, while Kee Step® allows that route to continue safely over obstacles.

Combining the two can create a continuous access route between the roof entry point and equipment requiring maintenance.

Kee Guard® Roof Edge Protection - Where routes pass close to exposed roof edges, Kee Guard® can provide permanent collective edge protection.

Kee Gate® Safety Gates - Self-closing safety gates can protect ladder openings and other access points while maintaining controlled movement around the roof.

Lifeline and Fall Protection Systems - Where collective protection cannot reasonably provide all the required protection, suitable lifeline, restraint or fall arrest systems may form part of the overall safety strategy.

The appropriate combination should be determined through a site-specific risk assessment.
