SR60+ - Trapezoidal Roof Deck Profile

Premium sinusoidal profile for industrial, commercial and distribution roof systems. Cover width 850mm, 60mm depth, engineered for spans up to 5.2m with proven load performance across three steel gauges.

Available in galvanised and polyester white finishes. Supplied to BS EN 10346:2015. Complies with BS 5427:2019 for material and BS 476 Pt7 for fire performance (Class 1).

SR60+ is designed for modern roof decking applications where strength, durability, and speed of installation are key. Its profile depth and wide coverage make it ideal for commercial, industrial, and large-scale residential projects.

The underside can remain exposed for an industrial aesthetic, or specified with polyester white coatings to create a brighter soffit finish and reduce the need for additional lining.

Efficient Spanning Capability
With a 60mm profile depth and gauges of 0.7mm, 0.9mm and 1.2mm, SR60+ is engineered to span longer distances with fewer supports. This reduces secondary steelwork, saves installation time, and provides cost-efficient roofing solutions.
High Load Capacity
Thanks to its optimised section properties, SR60+ handles both gravity and uplift loads effectively, ensuring strength and stability even under demanding conditions.
Corrosion Resistance
Offered with galvanised coating (Z275) or polyester white finishes, SR60+ is suitable for a wide range of environments, from standard commercial roofing to high-spec industrial applications.

Long Lengths: Manufactured in lengths up to 12m, reducing the number of joints and speeding up installation.
Long Lengths: Manufactured in lengths up to 12m, reducing the number of joints and speeding up installation.
Straightforward Fixing: Every trough requires main fixing at supports, with 150mm end laps, providing quick and secure installation.
Optimised Handling: At 850mm cover width, SR60+ offers excellent sheet coverage while remaining lightweight for on-site efficiency.
Reliable Side Laps: Installed at 850mm centres for enhanced stability and performance.

I have been using RMD profiles for a number of years and I can honestly say they are an amazing company to use . From the moment you contact them they make your project they're priority , they are very friendly, professional and cannot do enough for they're customers . During all my years of estimating I have never even gone to another decking company as I know from experience RMD profiles offer a 5 star service and I will be using them for many more years to come .

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. Our builders had originally proposed a beam and block solution for the ground floor over our basement excavation, and had never come across steel decking in a domestic property. They absolutely love it now - and intend to completely abandon beam and block in favour of this for all future projects. They found it quick and easy to work with, and we actually started pouring concrete the same day it was delivered. It's been great working with a team who are so enthusiastic about both their product, and their customer support. Big thanks to Matt!

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.
