Metfloor 80 - Composite profile

The Ultimate in lightweight steel decking is even better with exceptional span capabilities.

MetFloor 80 composite metal flooring

MetFloor® 80 is a deeper trapezoidal composite floor deck made from S350 steel. The 80 refers to the height of the profile in mm to the shoulder, before the dovetail of the profile. In this case it is 80mm.

Like MetFloor 60 it differs from MetFloor 55 which is a dovetail design deck system. MetFloor 80 is the amazing result of our extensive redevelopment & enhancement of the second generation of composite decking. Metfloor 80 represents the best of the 3rd generation composite floor designs.

MetFloor 80 offers a number of advantages over both MetFloor 60 & MetFloor 55, as it offers you the customer an exceptional span capability, with the potential for spans over and above those of MetFloor 60. Even with reduced concrete volume, it still offers an exceptional acoustic \ sound insulation, whilst being a more environmentally sustainable option.

Like MetFloor 60, MetFloor 80 is engineered with optional closed end \ end crush. Crushing the ends give exceptional fire protection, enhanced acoustic properties, and requires no filler blocks, making on site installation a breeze. It is also aesthetically very pleasing.

This MetFloor 60 profile is designed with trough stiffeners (ribs to the base of the trough); and joining laps formed assymetrically to allow for both interlocking and the shear studs to be placed centrally in both the troughs. As a result there is less need for on site checking. See diagram for details.

MetFloor® CMF design Software

No matter which MetFloor® profile is chosen the same state of the art CMF deck design software package is utilized. The software incorporates the construction stage & composite slab tests carried out at Imperial College, London together with fire tests carried out at Pavus in the Czech Republic under the management of the SCI (Steel Construction Institute).

This software enables the designer to carry out a deck \ slab design including line loads or punching shear checks in a simple but precise manner. Once the design is finalised, a comprehensive set of calculations can be printed, these are stamped with the SCI “ASSESSED” logo. CMF is the ONLY decking manufacturer to have carried out this SCI assessed ratification for all its profiles.

Profile Summary

Metfloor 80 - Composite profile diagram

Long span capability equals less cost
The smarter curved profile of MetFloor 80 gives you the potential for exceptional unpropped span, far greater than that of MetFloor 60, reducing structural steel requirements & costs. This capability makes Metfloor 80 the profile of choice for the longest span projects.

Safer Manual Handling
With a standardized cover width of just 600mm sheets are lightweight, and can be handled safely.

More Environmentally Sustainable
Greater span capability equals less concrete equals improved environmental sustainability.

Optimised Composite Action
Enhanced profile design with trough stiffeners and positioned side laps equals guaranteed centrally placed studs equals less on site checking.

End Crush – Equals Good Aesthetics & Safety
MetFloor 80 has the optional “end crush” feature, which eliminates the need for end caps to be installed on site. The benefits of this are quicker installation time, a more aesthetically pleasing finish, and enhanced fire & acoustic performance. This end crush finish is ideal for multiple single span condition projects commonly found in car park construction. There are also structural benefits with optional end crush.

Excellent Acoustic & Fire Performance.
All Metfloor profiles have exceptional fire protection and acoustic performance. End crush enhances this exceptional performance even further without the need for filler blocks, and simplifies installation.

Design
Metfloor 80 is ideally suited for all multi rise constructions, in particular car park design. Due to its’ exceptional spanning capability column spacing can be maximized for optimized capacity. It also offers impressive speed of installation; reduced carriage requirements; reduced structure, weight & height; and a working platform during construction.

Car parks & their users will benefit from the protection that MetFloor provides against the external environment. A lightweight roof will also provide additional protection against inclement weather. The aesthetics can be further enhanced by allowing the building to mellow over time, allowing it to lose its dazzling appearance and develop a more pleasing patina. Maintenance costs over the long run will thus be reduced.
