ComFlor 51 - Holorib Type profile

The ComFlor 51 can achieve spans of up to 3.5 metres, depending on the concrete depth and load requirements.

This minimises the need for intermediate supports, reducing construction time and material costs.

This profile is ideal for projects requiring fast installation, lightweight slabs, and clean soffits, while maintaining compliance with British and European structural design codes. ComFlor 51 offers a cost-effective solution with proven fire resistance and acoustic performance, making it suitable for multi-storey buildings and refurbishment works.

Watch this short video for a quick explanation!

Optimised Concrete Usage:
The trough design of the ComFlor 51 reduces the volume of concrete required, offering significant cost savings and lowering the overall slab weight. This results in a more efficient structural design.
Acoustic Performance:
The profile offers excellent noise insulation, ideal for residential and office environments. Additional acoustic treatments can further improve sound absorption and transmission reduction.
Fire Resistance:
The profile can achieve fire ratings of up to 120 minutes, ensuring compliance with building regulations and enhancing safety for occupants.

Acoustic Performance:
The profile offers excellent noise insulation, ideal for residential and office environments. Additional acoustic treatments can further improve sound absorption and transmission reduction.
Logistics and Installation
Efficiency: Each artic load can deliver approximately 800–900 m² of decking, optimising transport efficiency and minimising on-site storage needs. The lightweight panels simplify handling and speed up installation.
Concrete Depth Flexibility:
ComFlor 51 supports a range of concrete depths, typically from 100 mm to 200 mm, making it adaptable to various project specifications and load requirements.

TECHNICAL SPECIFICATION

Technical

Designed to Eurocode EN 1993-1-3 for cold-formed steel sections – View Eurocode summary.

Compliant with BS 5950 Part 6 for profiled sheeting in structural design – BSI Group summary.

Follows good practice guidance from the Steel Construction Institute – SCI P300 Publication.

ComFlor 51 Structural Performance & Design Guidance

ComFlor 51 is designed to achieve unpropped spans up to 3.5 metres, depending on slab depth, concrete strength, and imposed loads. This reduces the need for temporary propping and lowers overall construction costs.

ComFlor 51 Load and Span Design Codes

Eurocode 4 (EN 1994-1-1): Governs composite steel and concrete structures with national annexes applicable in the UK.

BS 5950-6:1990: British Standard for composite slabs, still referenced for legacy projects.

Key Design Differences:

British Standards often require reinforcement bars in the troughs for single-span slabs to control cracking.

Eurocode allows design flexibility with mesh or bars, depending on imposed loads and slab thickness.

National Annexes specify factors such as load combinations and partial safety factors.

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.
