Benefits of FibreFlorCost Savings

Labour cost savings

Up to 20% programme savings

No mesh to purchase, transport or store

Reduction in crane hire costs

Potential concrete volume savings

Easier to Install

No hoisting / lifting or manual handling of mesh

No steel fixing/tying requirements

No spacer requirements

3-Dimensional reinforcement delivered ready mixed

in concrete

Easier concrete application (No trip hazards or snagging

from mesh)

Fibre reinforcement always in the correct position

Technical Superiority

Independent testing proves that the FibreFlor system

provides equivalent or superior performance to traditional

welded wire mesh solutions.

Quality assured concrete reinforcement system.

FibreFlor is proven to reduce plastic shrinkage and

settlement cracking.

Unlike macro-synthetic fibres, the micro-synthetic fibres

in FibreFlor are also proven to mitigate the explosive

spalling tendency of concrete during fires.

The inclusion of steel fibres in FibreFlor provides load

bearing capabilities, increased toughness and long term

crack control.

FibreFlor is a partnership between Corus and Propex

Concrete Systems, the worlds largest supplier of fibre

reinforcement for concrete. FibreFlor uses a combination

of high performance steel fibres and polypropylene

micro-synthetic fibres to provide a three dimensional

fibre reinforced concrete composite slab.

Traditionally composite metal deck construction utilises

mesh fabric reinforcement. This involves the delivery, lifting

and installation of welded wire mesh on to the floor prior to

the pouring of concrete. The time and costs involved make

mesh relatively unpopular with contractors and the mesh

itself is a hindrance to other site operations. Maintaining

the correct mesh height, position, concrete cover and laps

can be difficult during mesh placement and concrete

pouring.

FibreFlor reinforcement is provided within the concrete,

delivered and ready to pump at site. Significantly this can

reduce installation times by up to 20%.

FibreFlor is a certified floor deck system that eliminates the

need for steel wire mesh and is currently available as

FibreFlor CF51, FibreFlor CF60 & FibreFlor CF80.

The benefits of Corus composite floor decking

Professional SupportCorus Panels and Profiles maintains a friendly technical

help desk, which is freely available to all Consulting

Engineers and Contractors to assist in Composite flooring

design issues. The technical help desk is available

on 0845 30 88 330.

The comprehensive Comdek software is also freely

available to all professionals who register at

www.coruspanelsandprofiles.co.uk

QualityTo provide the best quality and the most up to date design

information, Corus Panels and Profiles is quality assured to

BS ISO 9001:2000 Quality systems. Corus Panels and

Profiles is an active member of MCRMA (Metal Cladding

and Roll Forming Manufacturers Association), The SCI

(Steel Construction Institute), BCSA (British Constructional

Steelwork Association) and supports the research and

development industry wide.

The widest range of shallow decksFrom ComFlor 46 all the way to ComFlor 100 the Corus

range of decks provides the optimum solution for all over

beam applications.

Covering unpropped construction from 2.5 to 4.5 metres

each ComFlor profile offers particular application benefits.

The shallow decks are suitable for conventional composite

construction where the deck is placed onto the top flange

of the steel support beam.

Two deep composite floor decksComFlor 210 and ComFlor 225 are both designed to be

used with the Corus Slimdek system, which uses

asymmetric beams. The floor deck lands on the wider

bottom flange of the Asymmetric beam.

With typical unpropped spans extending to 6 metres and

propped spans to 9 metres the deep decks provide clear

open space between beams. The deck is contained within

the beam depth, which provides a very shallow floor zone.

The shape of the deck profiles allow for service integration

and the whole system provides inherent fire resistance.

ComFlor 46

Nestable

The ultra efficient nesting capability

of ComFlor 46 reduces the

transport volume of the product.

This fact combined with the

simplicity of ComFlor 46 also

makes it ideal for export.

Easy service suspension

Ceilings and lightweight services

can easily be attached to the

punched hangar tabs, which can be

included with ComFlor 46. These

must be specified at time of order.

Low concrete usage

The trapezoidal shape profile of

ComFlor 46 reduces the volume

of concrete used, with resultant

savings in structural and foundation

costs.

Quick reference tablesThe quick reference load/span and fire designtables, on the following 2 pages are intended asa guide for initial design, based on theparameters stated below the tables. Full designcan be carried out using the free Comdeksoftware. Please refer to page 70 for help on using the software.

Anti-crack meshBS 5950: Part 4 currently recommends that anti-crack mesh should comprise 0.1% of slab area.The Eurocode 4 recommendation is that anti-crack mesh should comprise 0.2% of slab areafor unpropped spans and 0.4% of slab area for

propped spans. The mesh shown in the quickreference tables complies with EC4 and thedesign program defaults to these values. WhereEC4 mesh rules are used, the mesh may bereduced midspan - see Design Information onpage 32. The reduced British Standard meshvalues may still be used by overriding this defaultin the design program.

Where forklift truck (or other similar concentratedloading) is expected 0.5% minimum percentagereinforcement should be used over the supportsand 2% elsewhere to control cracking. Forfurther information refer to Design Notes on page 32 or SCI AD150.

Mesh top cover must be a minimum of 15mm,and a maximum of 30mm. Mesh laps are to be300mm for A142 mesh and 400mm for A193,A252 & A393 mesh.

FireFor details of the performance of compositeslabs comprising ComFlor 46 decking under a fire condition with nominal anti-crack mesh,please refer to the quick reference fire load tablesin this brochure. For other simplified designcases or for full fire engineering, refer to theComdek software.

Shear studs

The wide trough of ComFlor 51

permits a flexible and efficient

placement of shear studs.

Fire performance of the

composite beams

Even for two hours fire rating, the

top flange of the steel beam does

not require fire protection, when

used with ComFlor 51 composite

deck.

Under floor services

Services are easy to attach to

ComFlor 51, with the ribs

presenting a dovetailed recessed

groove in the concrete slab at

152.5mm centres. This provides the

perfect connection for service

hangars via a wedge nut or similar

type device.

Fire performance of the slab

The dovetail presents a very small

opening and contributes little to the

transfer of heat through the slab in

the event of fire. Thus a lesser slab

depth is needed for fire design

purposes.



ComFlor 51 is a traditional dovetail re-entrant composite

floor deck. This profile provides an excellent mechanical

key into the concrete slab, offering a strong shear bond

performance, which is augmented by cross stiffeners

located in the profile trough. ComFlor 51 presents a

virtually flat soffit and a relatively thin slab is required to

meet fire design requirements.

floor deck. This profile provides an excellent mechanical

key into the concrete slab, offering a strong shear bond

performance, which is augmented by cross stiffeners

located in the profile trough. ComFlor 51 presents a

virtually flat soffit and a relatively thin slab is required to

meet fire design requirements.

ComFlor 60


ComFlor 60

Long-span capability

Optimised profile design gives

exceptional unpropped spanning

capability of up to 4.5 metres,

reducing structural steel

requirements and hence cost.

Reduced concrete usage

ComFlor 60 requires a reduced

concrete volume for any slab depth,

providing a more sustainable

solution and reducing costs.

Enhanced shear-stud interaction

Profile design guarantees central

shear-stud positioning to optimise

composite action, reducing the need

for on-site checking.

Excellent acoustic and

fire performance

Manufactured with closed ends to

give exceptional fire protection and

acoustic performance, while

simplifying installation.

Minimal maintenance

Available with Colorcoat pre-

finished steel for durability and

improved appearance.

Safer manual handling

With a cover width of 600mm,

sheets are lightweight, making them

safer and easier to handle.

ComFlor 60The latest addition to the comprehensive

range of flooring profiles by Corus


The ComFlor 60 composite floor profile offers the

ultimate in lightweight steel decking for all multi-rise

buildings. It combines exceptional spanning capabilities

with reduced concrete useage to provide a cost-effective

and attractive floor solution thats easy to install.

The state-of-the-art profile has been developed using

roll-forming techniques pioneered by Corus, drawing on

our 20 years of experience in designing advanced

composite floor systems.

Engineered with optional closed ends, ComFlor 60

provides excellent acoustic performance and fire

protection, with no requirement for filler blocks. Its profile

has been specially designed with trough stiffeners and side

laps positioned to guarantee centrally placed shear studs.

The cover width is just 600mm, creating lightweight

sheets that are easy to handle delivering significant

on-site safety benefits.

ComFlor 60 sheets are available with a Colorcoat

pre-finished steel coated underside giving a durable and

attractive appearance and minimising future maintenance.

Quick reference tablesThe quick reference load/span and fire designtables, on the following 2 pages are intended asa guide for initial design, based on theparameters stated below the tables. Full designcan be carried out using the free Comdeksoftware available. Please refer to page 70 forhelp on using the software.

Anti-crack meshBS 5950: Part 4 currently recommends that anti-crack mesh should comprise 0.1% of slabarea. The Eurocode 4 recommendation is thatanti-crack mesh should comprise 0.2% of slabarea for unpropped spans and 0.4% of slab area

for propped spans. The mesh shown in the quickreference tables complies with EC4 and thedesign program defaults to these values. WhereEC4 mesh rules are used, the mesh may bereduced midspan - see Design Information onpage 32. The reduced British Standard meshvalues may still be used by overriding this defaultin the design program.

Where forklift truck (or other similar concentratedloading) is expected 0.5% minimum percentagereinforcement should be used over the supportsand 2% elsewhere to control cracking. Forfurther information refer to Design Notes on page 32, or SCI AD150.







Taking the 60 profile concept to a new dimension.

Closed ends: Produced on line during theroll-forming operation, ideal for single-spanconstruction, acoustic reduction, firestopping and to avoid filler blocks.

ComFlor 80

Central stud placement provides

superb composite action between

the beam and concrete due to the

stud being positioned exactly in the

centre of the trough. This ensures

the correct concrete cover to the

stud and hence, the full design

capacity of the stud is developed.

The central location of the stud also

reduces on-site checking to ensure

that the stud has been positioned

correctly.

Ideal for car parks

ComFlor 80 is available with a

Colorcoat pre-finished steel

underside for use in car parks,

giving a durable and attractive

appearance and minimising future

maintenance.

Excellent concrete usage means

that ComFlor 80 is very economical

compared to other similar decks.

Improved manual handling

The cover width of ComFlor 80 is

600mm, to reduce sheet weight and

improve handling.

The innovative profile design provides real benefits.

ComFlor 80 is fully tested with the

Fibreflor system to provide all the no

mesh benefits. See following pages

for the load tables and further design

information.

ComFlor 80The next generation of

profiled steel composite decks


ComFlor 80 is the next generation of profiled steel

composite decks; it is the only 80mm profile available in

Colorcoat pre-finished steel to provide a durable and

attractive appearance.

The large corner curvature detail provides a very efficient

profile. In conjunction with the higher grade of steel, it ensures

typical unpropped spans of 4.4m simply supported and in the

continuous condition, spans of 5m can be achieved.

The large spans achievable means less structural steel

and thus cost saving in the overall construction cost,

providing more scope for architects and engineers in their

design process.
