U Design Rooftop Platforms

 Most commercial buildings locate their ductwork, cable trays, plumbing, HVAC units, and other large, cumbersome equipment on rooftops. Placing these critical systems in such an isolated area can help protect your important machinery from accidents by untrained professionals, free up valuable interior space, and reduce noise pollution.

 Over time, constant foot traffic and weight can damage a roof’s protective outer membrane, making it susceptible to problems like water ingress that can threaten your building’s infrastructure. Furthermore, it can be hazardous for building and maintenance professionals to work on these systems at such great heights—especially if they’re relying on unsecured ladders and other temporary structures to reach equipment. With so many perils, it’s no surprise roofing accidents account for more than one-third of all fatalities in the construction industry.

 To give workers safe and easy access to rooftop equipment and systems while also preserving the structural integrity of your commercial roof, it’s vital you invest in reliable rooftop walkway platforms. Whether you need a single-access platform or you’re looking to create a full rooftop walkway design from scratch, our team of experts will help you build the most efficient and effective setup possible.

 Our U Design Rooftop Platforms allows you to easily create OSHA compliant and safe multi-directional access over pipes or any other rooftop obstacles. Standard parts below are manufactured in the highest quality aluminum for corrosion resistance, but we can also create these designs in FRP composite construction. Our special support feet distribute weight to prevent damage to roof membranes. You can select the parts needed to create your own specially configured U-Design rooftop platform by following the steps below the features table.



 • OSHA and ANSI compliant designs  • Grip Strut tread surface
 • 1”x 2“ Aluminum rectangular tube construction  • 500 lbs. rated capacity
 • Clearance height is 2.5” less than platform height  • 42”H guardrail height
 • Non-Penetrating caddy feet – distributes weight evenly  • 36”W Steps and bridge spans
 • 40”L bridge span that can be combined to create up to 120” uninhibited clearance length
