Steel Floor Decking Explained: Metfloor & Comflor Systems for Multi-Storey Projects
When it comes to building strong, stable, and cost-effective multi-storey structures, steel floor decking systems are at the heart of modern construction. Among the most trusted and widely used solutions in the UK are Metfloor and Comflor, both engineered for strength, speed, and performance on site.
In this article, we’ll break down the differences between Metfloor and Comflor, explain how steel decking contributes to multi-level structural integrity, and show why ConcreteSF is the UK’s reliable partner for supply and installation.
What Is Steel Floor Decking?
Steel floor decking is a structural component used to support concrete slabs in multi-storey buildings. The decking acts as both permanent formwork during construction and reinforcement once the concrete cures. It eliminates the need for temporary supports and accelerates build time significantly.
These systems are typically used in:
- Commercial buildings
- Industrial units
- Car parks
- High-rise developments
- Mixed-use retail and residential spaces
Benefits of Using Steel Decking Systems
- Speed of Installation – Lightweight and easy to handle, speeding up construction
- Load-Bearing Performance – Supports wet concrete during the pour and live loads after curing
- Cost-Efficient – Reduces need for formwork and scaffolding
- Fire Performance – Compliant with UK fire regulations when used with fire-rated concrete
- Sustainability – Made from recyclable steel, reducing carbon impact
Metfloor Decking Systems – Overview
Metfloor is a popular UK-manufactured steel decking system, known for its robust profile options and design flexibility. It includes:
✅ Metfloor 55

Comflor Decking Systems – Overview
Comflor, developed by Tata Steel, is another high-performance decking solution frequently used in multi-storey construction.
✅ Comflor 60 & 80
- Re-entrant profile design for superior composite action
- Reduced concrete usage
- Suitable for medium to long spans
✅ Comflor 210
- Deep deck design ideal for unpropped long spans
- Excellent acoustic and fire ratings
- Often used in car park structures and large-scale industrial developments
Why Choose Comflor?
- Enhanced spanning capabilities
- Thinner concrete slabs with reduced weight
- Detailed design software and load span tables available
How ConcreteSF Supports Steel Decking Projects
We are specialists in steel floor decking installation, with hands-on experience supplying and fitting both Metfloor and Comflor systems across the UK. Our complete service includes:
- 📐 Technical Consultation & Design Support
- 🚛 Supply of Steel Decking, Fixings & Mesh
- 🏗️ On-Site Installation by Qualified Teams
- 🔒 Safety-Compliant Work Including Edge Protection & Netting
We work closely with engineers, contractors, and developers to ensure the decking system meets the required load, span, and fire-rating standards for each project.
Why Steel Decking is Essential for Multi-Storey Construction
Without steel decking, multi-storey buildings would take significantly longer to construct, require more temporary support, and demand higher labour input. Using Metfloor or Comflor allows developers to:
- Reduce build schedules
- Improve site safety
- Lower material and labour costs
- Ensure compliance with UK structural and fire regulations
