Decking Systems

A traditional dovetail re-entrant composite floor deck. Its profile provides an excellent mechanical key into the concrete slab, offering a strong shear bond performance augmented by stiffeners located in the profile trough. 

MetFloor® 55 presents a virtually flat soffit and only a relatively thin slab is required to meet fire design requirements. Highly versatile and popular worldwide. It differs from our other MetFloor products by its shape – MetFloor® 60 & MetFloor® 80 are trapezoidal deck systems.

Shear studs – MetFloor® 55 has a wide trough which gives you great flexibility and efficiency when placing shear studs.

Composite beams’ fire performance – Even for two hours fire rating, the top flange of the steel beam does not require fire protection when used with MetFloor® 55 composite deck.

Under floor services – Services are easy to attach to MetFloor® 55, with the ribs presenting a dovetailed recessed groove in the concrete slab at 152.5mm to 150mm centres. This provides the perfect connection for service hangars via a wedge nut or similar device.

Slab’s fire performance – Because the dovetail has a very small opening, minimal heat is transferred through the slab if there is a fire, therefore when designing for fire purposes, you will need a smaller slab depth.

The ultimate in lightweight steel decking, MetFloor® 60 is a shallow trapezoidal composite floor deck with exceptional spanning capabilities and reduced concrete usage. The result is a highly cost- effective, attractive, and easy-to-install floor solution. The 60 refers to the height of the profile in mm to the shoulder, before the dovetail of the profile. In this case 60mm.

Like MetFloor 80 it differs from MetFloor 55 which is a dovetail re-entrant design deck system. MetFloor 60 offers a number of advantages over MetFloor 55, as it offers you, the customer, a far greater unpropped span capability, and requires less concrete. Even with reduced concrete volume, it still offers an exceptional acoustic & sound insulation, whilst being a more environmentally sustainable option.

Long-span capability – The smarter profile designs of MetFloor® 60 delivers exceptional unpropped spanning capability, helping to reduce structural steel requirements and costs.

Less concrete usage – As it needs less concrete volume for any slab depth, MetFloor® 60 delivers a more sustainable solution and helps reduces costs too.

Enhanced shear stud interaction – This profile is designed with trough stiffeners (ribs to the base of the trough); and joining laps formed asymmetrically to allow for both interlocking and the shear studs to be placed centrally in both the troughs.

Excellent acoustic and fire performance – If required this profile can be manufactured with closed ends to give exceptional fire protection and acoustic performance, while simplifying installation.

MetFloor® 80 is a deeper trapezoidal composite floor deck with even greater spanning capabilities than MetFloor® 60 & MetFloor® 55 together with reduced concrete usage. The result is a highly cost- effective, attractive, and easy-to-install floor solution. The 80 refers to the height of the profile in mm to the shoulder, before the dovetail of the profile. In this case 80mm.

Like MetFloor 60 it differs from MetFloor 55 which is a dovetail re-entrant design deck system. 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.

Long-span capability – The profile designs of MetFloor® 80 delivers exceptional unpropped spanning capability, helping to reduce structural steel requirements and costs.

Less concrete usage – As it needs less concrete volume for any slab depth, MetFloor® 80 delivers a more sustainable solution and helps reduces costs too.

Enhanced shear stud interaction – Enhanced design profile guarantees central shear-stud positioning to optimise composite action, so reducing the need for on-site checking.

Excellent acoustic and fire performance – If required this profile can be manufactured with closed ends to give exceptional fire protection and acoustic performance, while simplifying installation.
