You have already been introduced to MX-R, our channel-based, modular roof support system. The MX-R frames came with many benefits - adjustability, ease of configuration and bespoke, with high-load bearing capacities. 

Well now, we have repackaged all those benefits to create a modular access system called MX-R Access. Designed by keeping in mind the advantages of our MX-R roof support systems, MX-R Access is also MX channel-based and is therefore uniquely adaptable, easy to configure and bespoke to your needs. Not to mention - they are standard-compliant with the BS ISO 14122:2016.   

In this article, we will show you how MX-R Access can make navigating rooftops easy and efficient, whilst also being safe and compliant. 


What is MX-R Access? 

Rooftops often host a cluster of crucial services like AC units, ductwork, pipework, and more.  

When you need to maintain or inspect these rooftop units or services and require safe and easy access to them - you need a rooftop access platform. 

However, what we often see on many construction sites is the casual use of wooden pallets as makeshift steps and bridges to navigate pipework and ducting for maintenance access. 

This practice is a big “no-no” in the world of safety and compliance, as specified in the BS ISO 14122 i.e., the standard requirements for the stability and load capacity of access platforms.  

That is where MX-R Access comes in! 

MX-R Access is a bespoke and adjustable roof access platform that is designed to help your site team traverse rooftop services and have access to rooftop equipment, making inspections and maintenance possible.  

MX-R Access includes a range of access platforms, including: 

  • 𝗦𝘁𝗲𝗽𝗼𝘃𝗲𝗿𝘀: These act as bridges over obstacles, reducing the risk of trips and stumbles whilst maintaining plant equipment. 
  • 𝗪𝗮𝗹𝗸𝘄𝗮𝘆𝘀: Anti-slip walkway systems designed to protect both the roof and the workers. 
  • 𝗣𝗹𝗮𝗻𝘁 𝗔𝗰𝗰𝗲𝘀𝘀 𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀: Providing elevated access to essential plant components. 
  • 𝗖𝗼𝗺𝗯𝗶𝗻𝗲𝗱 𝗦𝘂𝗽𝗽𝗼𝗿𝘁 𝗮𝗻𝗱 𝗔𝗰𝗰𝗲𝘀𝘀 𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀: A comprehensive solution that combines plant access with support.

Now you might be wondering… 


Why is there a need for MX-R Access? 

As mentioned above, there is a great need in the construction industry for safe maintenance access on construction sites rather than makeshift solutions, to avoid workplace accidents and injuries.  

This is why we ensured that MX-R Access is a system that keeps safety and compliance in mind and is designed in accordance with the health and safety standards set by the BS ISO 14122.  

The BS 14122 sets specific requirements for the stability and load capacity of access platforms and walkways.  

Here are some of the essential requirements of the BS 14122 that MX-R Access is designed to meet: 

Load Capacity 

 The BS 14122 sets specific requirements for the stability and load capacity of access platforms and walkways. As per its guidelines, MX-R Access has been tested against a 1.5kN of force (152.96kg) load bearing capacity, and therefore, comes with reliable test data to evidence this. As you may already know, evidencing your structure’s load bearing capacity is an integral part of not just the BS ISO 14122, but also the 2022 Building Safety Act and the ‘Golden thread’ secondary legislation which mandates that all contractors must be able to demonstrate the performance of their installations with reliable test data.   

Naturally, stacked wooden pallets are not designed for footing with these criteria in mind. They lack the structural integrity to support the weight of individuals moving across them or performing maintenance tasks, and additionally lack any reliable test data to provide a clear indication of the same. 

Handrails and Guardrails  

The standard outlines requirements for guardrails and handrails, such as height and strength, to prevent workers falling from dangerous heights. Accordingly, MX-R Access is designed with a standard 42mm OD handrailing to fulfil the requirements of BS 14122.  

 Durability and Non-Slip Material  

Compliant access platforms and walkways should be constructed from durable and non-slip materials designed to withstand outdoor and industrial environments. This is followed by MX-R Access in many ways. Here are some design considerations that ensure this: 

  • The rubber feet spread the load out evenly without penetrating the roof membrane. 
  • All metalwork comes with a hot dip galvanised finish to withstand harsh environmental conditions. 
  • The width is kept to a standard of 800mm. 
  • It contains 38mm, non-slip GRP grating as standard. 
  • A heavy-duty stringer is added for stability. 
  • For platforms over 500mm tall, toe plates and kick plates are included. 

So, there you have it! MX-R Access is designed to give everyone on site a safe working environment, free from health and safety risks. Remember, safety and compliance aren’t just about following specific standards and guidelines. It is about having evidence and test data to demonstrate that you have truly followed safety and compliance procedures and have the ability to prove it when asked.    

But that is not all that MX-R Access has to offer!

What are the advantages of MX-R Access? 

Adherence to the BS ISO 14122 is a standard requirement that all rooftop platforms and walkways should follow. But here is where the MX-R Access truly goes above and beyond to make rooftop access not just safe and compliant, but also easy and efficient. 


MX-R Access is exceptionally versatile and can be customised to design and build almost every rooftop access requirement.  

For instance, here are some of the access requirements that MX-R Access can be adapted to: 

  • Raise up to 7 steps and up to 1.5m of clearance 
  • Raise to a second platform height. 
  • Turn corners. 
  • Accommodate taller platforms with bracing. 
  • Up to 5 degree of roof pitch adaptability 


MX-R Access only makes use of off-the-shelf components in interchangeable configurations along with standard MX channel profiles to ensure that any job can be designed without the need for bespoke parts.  

This allows MX-R Access to be designed to your access requirements quickly and efficiently using a core selection of components and CAD models. 

This ultimately guarantees a fast design and delivery process, helping you stay ahead of project deadlines safely and reliably.  


Alongside its bespoke off-the-shelf designs, MX-R Access also comes with legs that are height adjustable up to 100mm. 

Fast Installation 

The MX-R Access system is also delivered in manageable sections for easy transportation and lifting. Once the product reaches your site, the sections can be quickly re-connected by following assembly instructions. If desired, the complete unit can be supplied in component form for assembly on site.  


What if we told you that you can now have access to a standard-compliant, adjustable, and bespoke rooftop access solution without breaking the bank? 

Good news – With MX-R Access, now you can! 


In conclusion, MX-R Access represents a significant leap forward in rooftop access solutions, offering a comprehensive range of benefits that address the critical needs of safety, compliance, and efficiency in the construction industry. Designed with the advantages of the MX-R roof support system, MX-R Access ensures that maintenance access on construction sites is both safe and compliant with the BS ISO 14122 standards. Its load-bearing capacity, handrails, durability, and non-slip materials are all in alignment with these requirements. Moreover, MX-R Access distinguishes itself by offering bespoke, off-the-shelf, and adjustable access solutions that can be tailored to meet specific rooftop requirements.
