SR100+ - Deep Trapezoidal Roof Deck Profile
Key Features and Benefits
Superior Spanning Capability
With a 100mm deep profile and gauges of 0.7mm, 0.9mm, and 1.2mm, SR100+ is designed for long spans and high load performance. This reduces the need for additional secondary steelwork, delivering material and cost savings on large roof areas.
High Strength-to-Weight Ratio
SR100+ offers excellent structural efficiency. Despite its lightweight nature (9.47–16.29 kg/m² depending on gauge), it provides outstanding resistance to both gravity and uplift loads, making it ideal for demanding roof designs.
Fire Performance
Fully compliant with Class A1 Reaction to Fire, Class 1 (BS476 Part 7), and Class O Building Regulations, SR100+ provides excellent safety performance in line with UK standards.
Coating Options for Durability
Available in galvanised (Z275) or polyester-coated finishes, SR100+ ensures long-term corrosion resistance across a wide range of environments.
Logistics and Installation
Extended Lengths: Manufactured up to 12m to minimise joints and speed up installation.
Secure Fixing: Main fixings required in every trough with 150mm end laps, ensuring robust connections.
Wide Coverage: With 720mm cover width and 240mm pitch, SR100+ balances installation efficiency with high structural performance.
Side Lap Security: Installed at 450mm centres, providing stability under both gravity and uplift conditions.
Applications and Aesthetic Flexibility
SR100+ is ideally suited to large-scale roofing projects where long spans, reduced purlin requirements, and high structural performance are essential. It is particularly effective in industrial, commercial, and distribution centre builds.
The underside can be left exposed for an industrial finish or coated for enhanced aesthetics, including bright polyester white for improved light reflection inside the building.
Aesthetics and Finishes:
A variety of colours and paint finishes can be applied to the underside of the deck to create an attractive finish, while also contributing to fire safety compliance. Please contact us for further details.

"Matthew, Sean & Craig was extremely helpful from tendering, advice design and pre start site meetings"
Matthew, Sean & Craig was extremely helpful from tendering, advice design and pre start site meetings. We had to delay the start date by a week and this was not an issue with RMD they accommodated the move and done everything they could to accelerate their install to help us make some time up.
The Install team worked extremely hard and done a great job.
Would highly recommend RMD Profiles and look forward to working with them on Future projects.

Matt and his team are amazing, knowledgeable, professional and supportive. We have been working on numerous projects since 2021 and would recommend for profile decking supply and fit. Their service is commendable. Thank you Matt and team RMD, keep up the good work!

"It's been great working with a team who are so enthusiastic about both their product, and their customer support."
We initially obtained quotes for five similar competitive products. RMD was the best quote, but more importantly their support and lead time made our decision a no-brainer. Once we decided to go with RMD, Matt was able to accommodate some very specific cuts and get it loaded the same day we called. The delivery arrived as promised the next morning, and the delivery guys were terrific. We were delighted with the support provided, and love the product.
