Corus Panels and Profiles offer an attractive and economic

range of roof profiles to meet both the aesthetic and

structural requirements of the designer.

Load/span figures

These tables are based on a total ‘dead’ and ‘super

imposed’ load of 1.20 kN/m2 and a deflection limit of

L/200. The quoted spans are more onerous than the

profiles maximum allowable spans when subjected to wind

suction loads. Therefore, the tables can be used as a

conservative guide for loading in either direction. For

differing conditions please consult our full load tables

and/or consult our Technical Services Department.

Curving

Self curving can induce stress marking in the sheet. The

figures shown have been chosen with aesthetics in mind

and therefore minimise visible induced stress. Self curved

panel ends laps will ‘birdmouth’ slightly, therefore long

sheet lengths are recommended to reduce the number of

end laps. Factory curved data relates to a single convex

curve. Information regarding double or wave curves must

be obtained from Corus Panels and Profiles.

Finishes

The data held within this table concerns itself with our

standard product range. Non standard materials, gauges,

colours and coatings are available to special order, subject

to quantity required and extended lead time.

Corus Panels and Profiles offer an attractive and economic

range of wall profiles to meet both the aesthetic and

structural requirements of the designer.

For flexibility of design these profiles can be reversed. In

this situation the equivalent roof profile (‘R’ suffix) should

be specified with side lap installed as per the roofing

method.

Curving



and therefore minimise visible induced stress. End laps will

‘birdmouth’ slightly on self curved cladding.

Factory curved data relates to a single convex curve.

Information regarding double or wave curves must be

obtained from Corus Panels and Profiles.

Horizontal applications

Corus Panels and Profiles have indicated the profiles that,

through experience have given good service when laid

horizontally. This being based on the necessary greater

attention being paid to in-plane steelwork tolerances.

Load/span figures

These tables are based on an effective positive wind load

of 1.00 kN/m2 and a deflection limit of L/150. The quoted

spans are more onerous than the profiles maximum

allowable spans when subjected to identical negative

pressure/wind suction loads. Therefore, the tables can be

used as a conservative guide for loading in either direction.

For differing conditions please consult our full load tables

and/or consult our Technical Services Department.

Corus Panels and Profiles offer a range of lining panels

specifically developed to be compatible with our outer

sheet product range thus allowing the accommodation of

modular rooflights.

Lengths

Being roll formed, long lengths are available but for

practical site handling purposes with the 0.40 mm gauge

options we would suggest these are kept to a maximum

of 5m.

Vapour Barrier

All non-perforated profiles provide a side lap which can be

sealed to provide a vapour check. A correctly sealed lining

panel will easily meet the 10m3/hr/m2 @ 50 pascals air

tightness requirement of the new building regulations.

Spans

In roofing conditions, the spanning capabilities of the lining

panels are largely dependent upon their self-weight and the

weight of the insulation they are required to support. In

normal conditions with 0.40mm gauge liners double span

capabilities of up to 2m can be achieved. However, at

spans approaching maximum it may be necessary to

mechanically fix side laps and/or reverse the normal side

lap to minimise separation. The span for non fragility rating

may be less than span shown in tables. Contact our

Technical Department for fixing details to comply with

ACR(M)001:2000.

Fire Rating

All non perforated lining sheets provide a fire rating of

Class 1 to BS476: Part 7 and Class 0 in accordance with

current Building Regulations.

Curving



and therefore minimise visible induced stress. Figures are

also based on the profile being fitted above the purlin on a

convex curved roof. Factory curved data relates to a single

convex curve. Information regarding double or wave curves

must be obtained from Corus Panels and Profiles.

Acoustics

To meet the increasing demand for noise reduction in

factories and public buildings Corus Panels and Profiles

can supply lining panels with acoustic perforations

incorporated in the flat pans of the profile.

When correctly installed, these panels can provide a high

level of acoustic absorbency instead of the reflective finish

normally presented by plain metal sheeting. Whilst other

patterns can be achieved the standard pattern is illustrated

in the table opposite. Percentage open areas are

highlighted next to the relevant profiles.

Lining Trays & Special Roof Profiles

Structural lining traysCorus Panels and Profiles can offer a structural lining tray

that is suitable for both roof and wall cladding applications

spanning across the main steels and omitting the need for

purlins or cladding rails.

Load/span figures

These figures are based on a maximum load of 1.50kN/m2

and a deflection limit of L/200.

In order to offer the specifier more choice, it is possible to

produce some of our more specialist sections adapted to

suit roof cladding applications. The necessary modifications

render these profiles ‘special’ and therefore may be subject

to a minimum order requirement and extended lead times.

For further information please contact our Sales Department.

Load/span figures

These tables are based on a total ‘dead’ and ‘super

imposed’ load of 1.20 kN/m2 and a deflection limit of L/200.

The quoted spans are more onerous than the profiles

maximum allowable spans when subjected to wind suction

loads. Therefore, the tables can be used as a conservative

guide for loading in either direction. For differing conditions

please consult our full load tables and/or consult our

Technical Services Department.

Gauges

The data held within this table concerns itself with the

minimum recommended gauges. Different gauges, colours,

coatings etc. can be made available subject to special order.

Pressed profiles are manufactured by brake press, which

offers flexibility in their design but limits the overall length

to 3.6metres. The brake press tool creates the rib profile

which means that the shape of this is fixed, however the

spacing of ribs may be varied to create interesting

aesthetic effects. Thus the crown and pitch are variable but

the rib shape is not. The minimum pitch available for each

profile is shown opposite.

Pressed profiles are used for fascias, soffits and to create

architectural effects such as infill panels in wall cladding.

Fire protection design guideusing steel wall claddingThe use of insulated profiled steel

cladding sheets is common practice

for external wall constructions on a

variety of different building types.

However, in certain situations these

walls are required to provide fire

protection and in these instances

specific Building Regulations have to

be complied with. Corus Panels and

Profiles offer a range of non-

loadbearing fully insulated fire

resistant wall cladding systems

available to meet Building Regulation

requirements for one hour and four

hour rated external boundary walls

and one hour separating/partitional

wall conditions.

This publication has been produced to

offer guidance on the methods

developed for fire containment when

using our coated steel cladding

products.

Firewall Systems

Support Structures

Sheeting Rails

To accommodate the thermal

expansion generated during fire all

sheeting rails must be fixed to support

cleats with slotted holes and bolts used

must have both steel and plastic low

melt washers under the head.

The rails should be positioned to create

maximum support centres for the

firewall not greater than 2m. Allowance

must be made for expansion in the rail

length and span condition for the rails

themselves should be single but may be

sleeved to achieve continuity.

Structural Frame

When sheeting rails heat up during a fire

they cease to function as structural

members. Therefore, to prevent the wall

moving downwards under its own self

weight either a support at the head or

base of the wall is required. All Corus

Panels and Profiles firewalls can be

designed to be supported

from eaves

beams/stanchions or

rafters and posts if

situated on a gable end.

However, these elements

must be protected using conventional fire

protection materials to give the same

period of fire resistance as the firewall.

Cavity Barriers

Where a cavity is created within the wall

construction cavity barriers are required

to be introduced at positions identified

by Building Regulations Approved

Document B.

On firewalls which use non-combustible

mineral fibre insulant and where the

design allows the quilt/board to

effectively seal the cavity against the

steel sheeting no additional barrier is

necessary. However, on systems where

the design incorporates an air gap a

cavity barrier is required positioned to

the full height of the wall at intervals not

exceeding 20m.

The basic technical performance

requirement for a cavity barrier is that it

must maintain integrity for 30 minutes

and provide at least 15 minutes fire

insulation as determined by test in

accordance with BS476 Part 22.

Cavity barriers should be fixed in a

manner that prevents displacement

under normal service conditions or in

a fire.

Building Regulations

Firewall Building RegulationsThe Building Regulations ApprovedDocument B - 2000 edition providesguidelines on acceptable forms of fireresistant structures encompassingconstruction, material performance, meansof escape and appropriate active fire controltechniques. These are categorised in thefollowing requirements:

B1 – Means of escapeB2 – Internal Fire Spread (linings)B3 – Internal Fire Spread (structure)B4 – External Fire Spread B5 - Access & Facilities for the FireService

All of these stipulations require close designintegration in order to establish effectivebuilding fire containment systems andsuitable evacuation procedures.

Whilst for the purpose of this brochure it isimpractical to cover all the conditionscontained within this document,Requirements B2 and B4 are the mostrelevant when considering the use of steelcladding systems. The following informationhas been produced as a guide to highlightsome of the basic criteria.

B2 - Internal Fire Spread (linings)

Requirement:

(1) To inhibit the spread of fire within thebuilding, the internal linings shall:-

(a) resist the spread of flame over theirsurfaces; and

(b) have, if ignited, a rate of heat releasewhich is reasonable in the circumstances.

All Corus Panels and Profiles claddingproducts manufactured from Corus organiccoated steel meet Classification 0. A description as to how this classification isobtained can be found within the BritishStandard 476 section of this brochure.

B4 - External Fire Spread

Requirement:

1) The external walls of the building shallresist the spread of fire over the wallsand from one building to another, havingregard to the height, use and position ofthe building.

2) The roof of the building shall resist thespread of fire over the roof and from onebuilding to another, having regard to theuse and position of the building.

Fire resistance standard:

The external walls of the building shouldhave the appropriate fire resistance given inTable A1, Appendix A of ApprovedDocument B (2000 edition).

This table stipulates specific provisions oftest for fire resistance of elements ofstructure stating required method ofexposure, integrity and insulation periodsbased on the distance from a relevantboundary.

Table A1 refers to Table A2 which in turngives a specific breakdown of fire resistanceperiods for buildings in certain purposegroups, building heights and whethersprinklered or not.

For example, an external non-loadbearingwall on an industrial unit up to 20m fromground level requires a minimum fireresistance period of 90 minutes (non-sprinklered) with an insulation period of 15 minutes.

All certified/assessed built up Corus Panelsand Profiles Firewall systems achieve 4 hours integrity and 15 minutes insulationand therefore would satisfactorily meet thiscriteria.

External Services:

The external surfaces of walls should meetthe provisions laid out in Diagram 36 of

Requirement B4, Section 12. A briefsummary of this diagram is tabulated below:

All Corus Panels and Profiles claddingproducts manufactured from Corus organiccoated steel meet Classification 0. A description as to how this classification isobtained can be found within the BritishStandard 476 section of this brochure.

External Wall Construction:

It must be noted that even though theprovisions for external surfaces may havebeen satisfied, on buildings that are inexcess of 15m above ground level theinsulation material used in the external wallconstruction should be of limitedcombustibility.

All insulation specified for use within CorusPanels and Profiles firewall systems can bedeemed ‘non-combustible’ in accordancewith BS476 Part 4 and would thereforemeet the criteria of this stipulation.

British Standard 476 provides anacceptable framework for meeting theserequirements within the U.K. and focuseson test related physical measurement inorder to establish fire rated performance forsteel cladding systems.

Reference is made to this standard inApproved Document B sections B2 to B4 -Internal and External Fire Spread.

British Standard 476

British Standard 476

BS476 is the recognised standard referred toin the Building Regulations and provides aframework for meeting fire performancerequirements within the U.K. This standardconcentrates on test related physicalmeasurement in order to establish the firerating performance of elements/constructions. The most relevant in relation toCorus Panels and Profiles organic coatedsteel cladding products/systems can behighlighted as follows:-

BS476 Part 3: External Fire Exposure Roof Test

Roofs are graded according to the resistancethey offer to external fire (e.g. from anadjacent building or compartment). This ismeasured in terms of penetration and flamespread. The U.K. Building Regulationsdesignate pitched roofs using profiled sheetsproduced from galvanised steel or organiccoated steel as Classification AA, the highestdesignation possible. Therefore, it can besatisfied that roofs constructed with CorusPanels and Profiles topsheet profiles inaccordance with manufacturer’s instructionswill achieve this rating.

Note: This standard has been withdrawn bythe British Standards Institution but continuesto be cited in the Building Regulations. Therelevant test method has therefore beenincluded as an annex within BS5427: 1996Code Of Practice for the use of Profiled sheetfor roof and wall cladding on buildings.

BS476 Part 4:

Non-Combustibility Test for Materials

All insulation products specified for use withinCorus Panels and Profiles firewall systemsachieve ‘non-combustible’ classification andtherefore meet the requirements laid downwithin Approved Document B4 Section 12, External Wall Construction.

BS476 Part 6: Methods of Test for Fire Propagation for Products

This test determines the contribution amaterial makes to the fire and is measured interms of heat contributed over a period oftwenty minutes. This is expressed as anindex of performance ‘I’ together with sub-indices i1, i2 and i3 which are assessed fromempirical formulae. These sub-indices relateto heat contributed over shorter time periods.

Organic coated steel Corus Panels andProfiles cladding products with for examplePVC, PVF2 and lining enamel type finisheshave an index ‘I’ not exceeding 12 qnd asub-index i1 (heat contributed in the first 3 minutes) not exceeding 6.

BS476 Part 7: Methods for Classificationof the Surface Spread of Flame ofProducts

This test grades material into classes 1 to 4according to the rate of flame spread acrossit’s surface. All Corus Panels and Profilescladding products produced from Corusorganic coated steel achieve Class 1 - thehighest grade offering the best resistance tospread of flame.

The Building Regulations have a higherClassification defined as Class 0, whichcombines results from BS476 Parts 6 and 7.A class 0 surface must have a Class 1 resultfrom BS476 Part 7 and a maximum index ‘I’of 12 and maximum sub-index i1 value of 6from BS476 Part 6.

Therefore, a Corus Panels and Profilescladding has a finish that achieves Class 0spread of flame in accordance with theBuilding Regulations.

BS476 Part 11: Method for assessing theHeat Emission from Building Materials

A material which is deemed ‘non-combustible’ in accordance with BS476 Part4 automatically complies with therequirements laid down for limitedcombustibility in accordance with BS476 Part 11.

This standard adopts a similar testmethodology to BS476 Part 4 but uses adifferent method for the calculation of results.

All insulation products specified for use withinCorus Panels and Profiles firewall systemsachieve ‘non-combustible’ classification inaccordance with BS476 Part 4 and wouldtherefore meet the limited combustibilityclassification.

BS476 Part 22: Methods fordetermination of the Fire Resistance ofnon-loadbearing elements ofConstruction

This standard concerns itself with theexposure of fire on one or both faces of thewall construction, the growth of which isdesigned to simulate a real fire occurrencei.e. in terms of speed of temperature rise,flashover point and eventual temperature peak.

Definitions of fire resistance are met in thecontext of two criteria:

Integrity:

The time taken before failure of the wallsystem to satisfactorily prevent the passageof flames and hot gases in accordance withthe test procedures laid down in thisstandard.

Insulation:

This must be non-combustible and restrictthe transmittance of heat from the source ofthe fire to the unexposed face of the wallconstruction.

Point of failure is deemed when the meantemperature on the unheated side of theconstruction exceeds 140°C above ambientor when the temperature of any surface pointacross the unexposed face reaches 180°Cabove the initial ambient.

Tables A1 and A2 in Appendix A of ApprovedDocument B (1992 edition) stipulate actualrequirements which can vary from 1/2 hourintegrity to 2 hours. Scottish regulationrequirements can vary from 1/2 hour integrityto 4 hours.

A comprehensive range of Corus Panels andProfiles wall cladding systems have beendeveloped and certified/assessed to BS476Part 22. These offer a range of insulationperformance from 15 minutes to the morestringent 1 hour requirement laid down forpartitional/separating walls.

These are shown in the SystemIllustrations/Specifications Section of thisbrochure. A quick reference table has alsobeen included and can be found on theinside front cover.

Updating Fire Requirements

As a result of the ongoing programme for therevision of British standards it is inevitablethat some will be withdrawn yet will stillremain being cited by the Building RegulationApproved Documents. It is thereforerecommended that designers reviewstandards and approved documents forcurrent status.

Acoustic Systems

Acoustic performance is an

increasingly important functional area

for steel roof and wall cladding

systems. Whether it be reducing noise

levels within a factory environment or

eliminating nuisance from sound in

residential areas, acoustic control is a

significant aspect of steel cladding

design.

In recognition of this, Corus Panels

and Profiles have conducted a

number of live acoustic tests. The

results have produced a broad range

of systems that meet sound reduction

and sound absorption standards

frequently specified by industry today.

site assembly. However, test results achieved under

laboratory conditions and actual site assembled results may

vary for any given system. Differences in the levels of flanking

sound transmission are quite often the reason for this.

A software programme developed collaboratively by

members of the MCRMA is available for acoustic system

modelling and computer prediction. For acoustic

requirements not met by the systems illustrated, please

contact the Corus Panels and Profiles Technical Department,

who will be pleased to model various constructions to

produce a computer prediction to meet your needs.

Corus Panels and Profiles also has experience in specialist

acoustic systems for Power Station applications. Ryehouse,

Killinghome and other similar projects has provided us with a

successful track record in this field.
