If you’re looking for rooftop support systems, why not take a look at our range of versatile, non-penetrative solutions for installing any kind of rooftop plant.
We have an extensive range of products suitable for installing all kinds of rooftop plant including air conditioning units, ducting, pipework, cable trays, high load equipment, stairs and walkways. Our solutions are versatile for use on flat and low-pitched roofs and offer a completely safe, non-penetrative solution to ensure the integrity of the rooftop.
Our modern, lightweight, modular solutions are quick and easy to install and are the best alternative to outdated methods of rooftop installations using timber, steel or concrete constructions. Using modern rooftop supports can be time-saving and labour cost-saving.
No two roofs are the same. Different layouts, accessibility, obstructions and more mean you may need a uniquely designed solution for every rooftop installation.
We offer a comprehensive technical support service to guide you throughout your project. Our technical team can provide bespoke designs with all the relevant load and wind calculations, taking into account all of the unique factors of your installation, to ensure the correct and most effective rooftop support systems are installed.
