Metek offer two basic structural flooring system options and single flexible roof substrate to suit project requirements.
Steel joisted
A lightweight, high performance floor option using our C section steel floor joists and a timber boarding.
Concrete decking
Profiled metal decking with a structural concrete topping for thin floor construction applications.
Roof decking
A lightweight roof deck using our C section steel joists and timber boarding, ready to recieve finishes and buildups.
Steel Joisted
Metek steel joisted floors uses lightweight steel C sections joists spanning horizontally between Metek walls then boarded with a timber deck.
Key Benefits
- Lightweight, upto 80% lighter than traditional construction
- Dry, stable, light weight construction, no wet trades
- Service integration within the cavity
- Robust Standard Details available for Acoustics
- Eliminates the requirement for propping
- Steel joists typically 250mm deep
- Fire performance provided by fire resistant plasterboard
- A rated under BRE green guide
- Future adaptable for Lifetime homes compliance
- Erection not weather dependant
- C sections eliminates risk of ‘squeak’ in steel lattice beam construction
- OSB/3 deck for floor joists, water resistant ply sheathing for roofs
- Greater spans possible than with composite concrete
- Faster construction compared with composite concrete floors
Key Benefits
- Thinner floor construction than steel joists; typically 170mm depth
- Profiled steel decking acts as permament shuttering for in-situ concrete
- Excellent acoustic performance
- Fire resisting upto 120 minutes without soffit treatment. Reduces the requirement for multiple layers of plasterboard and resilient bar used in steel joisted floors.
- B rated under BRE green guide
- Water impermeable
- Mesh and rebar reinforced concrete
- ‘Pull-float’ type U2 finish
Roof decking
Metek roof decking uses lightweight steel C sections joists spanning horizontally between Metek walls then boarded with a timber deck.
The system is compatible with most warm roof and inverted roof buildups including Single ply, Bituminous and Cold liquid applied. In addition the system can be designed to allow for private or communal terraces, brown roof, green roof and blue roof treatments.
The open supporting structure also allows for "hybrid" thermal insulation strategies where the cavity between joists is used to contain an element of thermal insulation allowing for higher thermal performance to be realised verses traditional roof decks.
Key Benefits
- Lightweight, upto 80% lighter than traditional construction
- Dimensionally stable
- Service integration within the cavity
- A rated under BRE green guide
- Compatible with Green, Brown & Blue roof systems
- Erection not weather dependant
