Comflor 60 Deck Profile

The Comflor 60 deck profile is a composite steel floor decking for the upper floors and mezzanines of steel buildings. A 60mm galvanized profiled sheet acts as both permanent formwork and reinforcement for the concrete slab poured on top, creating a strong, light floor. Civoool supplies it for fast multi-storey construction.

What Is the Comflor 60 Deck Profile?

The Comflor 60 deck profile is a roll-formed galvanized steel sheet, 60mm deep, designed to form composite concrete floors in steel buildings. Its shape combines trapezoidal and re-entrant ribs, a round-shouldered geometry that resists buckling and spans further than a plain deck. On-site, it does three jobs in turn. First, it provides a safe working platform for the trades laying the floor. Next, it serves as permanent formwork, holding the wet concrete in place with no temporary shuttering. Finally, once the concrete cures, the steel deck acts as tension reinforcement, bonding with the slab to form a composite floor. This combined role is what makes profiled decking such an efficient way to build raised floors.

How Composite Decking Works

The strength of a Comflor 60 floor comes from treating steel and concrete as a single structural unit. Concrete is excellent in compression but weak in tension, while steel is the opposite. By bonding the profiled steel deck to the underside of the slab, the deck takes the tensile forces at the bottom of the floor while the concrete carries compression at the top, exactly where each material performs best. The re-entrant, dovetailed ribs lock mechanically into the concrete, so the two cannot slip apart under load. Shear studs welded through the deck onto the supporting beams extend this composite action to the steelwork itself, tying slab and beam together. The result is a floor stiffer, stronger, and lighter than concrete alone could achieve.

Long Spans, Less Concrete, Lighter Floors

A well-designed deck profile lets a floor span further with less material, and Comflor 60 is built around that idea. Its optimised, buckling-resistant shape can span up to 4.5 metres unpropped, allowing concrete to be poured without temporary supports below, which speeds construction and clears the space below. Because the profile is efficient, it requires less concrete for a given slab depth than a flat soffit would, reducing both the wet weight during the pour and the long-term dead load on the structure. Less concrete and longer spans together reduce the amount of supporting steel a building needs. Supplied at a 600mm cover width, each sheet stays light enough for safe handling while still covering ground quickly.

Where Comflor 60 Is Used

Comflor 60 suits almost any raised floor in a steel-framed building. It is the natural choice for mezzanine floors inside warehouses and factories, for the upper storeys of multi-level commercial buildings, and for structures such as car parks where a strong, fast floor is essential. Its re-entrant ribs are a practical bonus once the building is in use: services, ceilings, and fixings can be hung directly from the dovetail channels in the soffit, without drilling the slab. The deck also contributes to the floor’s fire and acoustic performance, and a clean profiled soffit can be left exposed where the look suits the space. Wherever a steel frame needs an efficient concrete floor, this profile fits naturally into the design.

Why Choose the Comflor 60 Composite Floor Deck

Faster Construction, Safe Platform

One of the strongest reasons to choose a Comflor 60 floor is speed. As soon as the sheets are laid and fixed, they form a safe, stable working platform, so following trades can get to work immediately rather than waiting for traditional formwork to be built. Because the deck is also the permanent formwork, there is no timber shuttering to erect and later strip out, and on spans up to about 4.5 metres, no propping is needed underneath. This keeps the floor below clear and usable while the slab above is poured and cured. Removing these slow, labour-intensive steps from the programme shortens the overall build time and lowers costs. For multi-storey projects, where each floor must be completed before the next begins, that saved time compounds at every level.

Strong, Efficient Composite Slabs

Beyond speed, the system simply makes better floors. The composite bond between deck and concrete produces a slab that is stronger and stiffer for its weight than a conventional reinforced floor, which means thinner slabs and lighter loads carried down to the columns and foundations. Lighter floors allow smaller beams and lighter framing, so the savings ripple through the whole structure. The deck also replaces much of the bottom-layer reinforcement that a traditional slab would require, reducing both steel-fixing labour and on-site material costs. With a profile that uses a low volume of concrete in the first place, the finished floor is an efficient use of every material, delivering the performance a building needs without the excess weight and cost of older methods.

Practical on Site: Services and Fire

A Comflor 60 floor is easy to live with long after the concrete has set. The dovetailed re-entrant ribs along the soffit act as ready-made fixing channels, so pipework, cable trays, ceilings, and other services can be hung straight from the underside of the floor without drilling into the slab. This saves time during fit-out and makes future changes simpler. The deck and slab together also provide useful fire resistance and help control sound transfer between floors, both of which matter in commercial and mixed-use buildings. Where the soffit will be seen, the clean profiled surface can be left exposed for a neat industrial finish, or boarded over. These practical details are why specifiers keep returning to a proven composite deck profile.

Engineered and Supplied by Civoool

As a complete steel building manufacturer, Civoool supplies the Comflor 60 deck profile as an integrated part of the structures it designs. The deck gauge, slab depth, span, and shear-stud layout are coordinated with the steel frame from the start, so the floor and the beams that carry it are engineered to work together as one composite system. Final spans and slab thicknesses are always confirmed against project-specific load and span tables and the relevant design codes. Sourcing the frame, secondary steel, and floor deck from a single supplier means a tighter, faster build and a floor whose performance is accounted for in the overall structural design, not added as an afterthought.
