Load/span figures 

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

imposed’ load of 1.20 kN/m 2 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.

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

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.

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. 

Due to the nature of pan perforating, some undulations may be evident in 

the final product.

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

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. 

See page 14 for special lining profiles.

Lining Trays & Special Roof Profiles 

Structural lining trays 

Corus Panels and Profiles can offer a structural lining tray

Pressed Profiles 

Pressed profiles, wall cladding, fascias and soffit lining 

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 

PR8

spacing of ribs may be varied to create interesting

Fire protection design guide 

using steel wall cladding 

The 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 nonloadbearing 

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. 

General Construction Requirements 

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.

following requirements: 

B1 – Means of escape 

B2 – Internal Fire Spread (linings) 

B3 – Internal Fire Spread (structure) 

B4 – External Fire Spread 

B5 - Access & Facilities for the Fire

suitable evacuation procedures. 

Whilst for the purpose of this brochure it is 

impractical to cover all the conditions 

contained within this document, 

Requirements B2 and B4 are the most 

relevant when considering the use of steel

Standard 476 section of this brochure. 

B4 - External Fire Spread 

Requirement: 

1) The external walls of the building shall 

resist the spread of fire over the walls 

and from one building to another, having 

regard to the height, use and position of 

the building. 

2) The roof of the building shall resist the 

spread of fire over the roof and from one 

building to another, having regard to the 

use and position of the building. 

Fire resistance standard: 

The external walls of the building should 

have the appropriate fire resistance given in 

Table A1, Appendix A of Approved 

Document B (2000 edition). 

This table stipulates specific provisions of 

test for fire resistance of elements of 

structure stating required method of 

exposure, integrity and insulation periods 

based on the distance from a relevant 

boundary. 

Table A1 refers to Table A2 which in turn 

gives a specific breakdown of fire resistance 

periods for buildings in certain purpose 

groups, building heights and whether 

sprinklered or not. 

For example, an external non-loadbearing 

wall on an industrial unit up to 20m from 

ground level requires a minimum fire 

resistance period of 90 minutes (nonsprinklered) 

with an insulation period of 

15 minutes. 

All certified/assessed built up Corus Panels 

and Profiles Firewall systems achieve 

4 hours integrity and 15 minutes insulation 

and therefore would satisfactorily meet this 

criteria. 

External Services: 

The external surfaces of walls should meet 

the provisions laid out in Diagram 36 of

It must be noted that even though the 

provisions for external surfaces may have 

been satisfied, on buildings that are in 

excess of 15m above ground level the 

insulation material used in the external wall 

construction should be of limited 

combustibility. 

All insulation specified for use within Corus 

Panels and Profiles firewall systems can be 

deemed ‘non-combustible’ in accordance 

with BS476 Part 4 and would therefore 

meet the criteria of this stipulation. 

British Standard 476 provides an

requirements within the U.K. and focuses 

on test related physical measurement in 

order to establish fire rated performance for

British Standard 476 

British Standard 476 

BS476 is the recognised standard referred to 

in the Building Regulations and provides a 

framework for meeting fire performance 

requirements within the U.K. This standard 

concentrates on test related physical 

measurement in order to establish the fire 

rating performance of elements/ 

constructions. The most relevant in relation to 

Corus Panels and Profiles organic coated 

steel cladding products/systems can be 

highlighted as follows:- 

BS476 Part 3: 

External Fire Exposure Roof Test 

Roofs are graded according to the resistance 

they offer to external fire (e.g. from an 

adjacent building or compartment). This is 

measured in terms of penetration and flame 

spread. The U.K. Building Regulations 

designate pitched roofs using profiled sheets 

produced from galvanised steel or organic 

coated steel as Classification AA, the highest 

designation possible. Therefore, it can be 

satisfied that roofs constructed with Corus 

Panels and Profiles topsheet profiles in 

accordance with manufacturer’s instructions 

will achieve this rating. 

Note: This standard has been withdrawn by 

the British Standards Institution but continues 

to be cited in the Building Regulations. The 

relevant test method has therefore been 

included as an annex within BS5427: 1996 

Code Of Practice for the use of Profiled sheet 

for roof and wall cladding on buildings. 

BS476 Part 4: 

Non-Combustibility Test for Materials 

All insulation products specified for use within 

Corus Panels and Profiles firewall systems 

achieve ‘non-combustible’ classification and 

therefore meet the requirements laid down 

within Approved Document B4 Section 12, 

External Wall Construction. 

BS476 Part 6: Methods of Test 

for Fire Propagation for Products 

This test determines the contribution a 

material makes to the fire and is measured in 

terms of heat contributed over a period of 

twenty minutes. This is expressed as an 

index of performance ‘I’ together with subindices 

i1, i2 and i3 which are assessed from 

empirical formulae. These sub-indices relate 

to heat contributed over shorter time periods. 

Organic coated steel Corus Panels and 

Profiles cladding products with for example 

PVC, PVF2 and lining enamel type finishes 

have an index ‘I’ not exceeding 12 qnd a 

sub-index i1 (heat contributed in the first 

3 minutes) not exceeding 6. 

BS476 Part 7: Methods for Classification 

of the Surface Spread of Flame of 

Products 

This test grades material into classes 1 to 4 

according to the rate of flame spread across 

it’s surface. All Corus Panels and Profiles 

cladding products produced from Corus 

organic coated steel achieve Class 1 - the 

highest grade offering the best resistance to 

spread of flame. 

The Building Regulations have a higher 

Classification defined as Class 0, which 

combines results from BS476 Parts 6 and 7. 

A class 0 surface must have a Class 1 result 

from BS476 Part 7 and a maximum index ‘I’ 

of 12 and maximum sub-index i1 value of 6 

from BS476 Part 6. 

Therefore, a Corus Panels and Profiles 

cladding has a finish that achieves Class 0 

spread of flame in accordance with the 

Building Regulations. 

BS476 Part 11: Method for assessing the 

Heat Emission from Building Materials 

A material which is deemed ‘noncombustible’ 

in accordance with BS476 Part 

4 automatically complies with the 

requirements laid down for limited 

combustibility in accordance with 

BS476 Part 11. 

This standard adopts a similar test 

methodology to BS476 Part 4 but uses a 

different method for the calculation of results. 

All insulation products specified for use within 

Corus Panels and Profiles firewall systems 

achieve ‘non-combustible’ classification in 

accordance with BS476 Part 4 and would 

therefore meet the limited combustibility 

classification. 

BS476 Part 22: Methods for 

determination of the Fire Resistance of 

non-loadbearing elements of 

Construction 

This standard concerns itself with the 

exposure of fire on one or both faces of the 

wall construction, the growth of which is 

designed to simulate a real fire occurrence 

i.e. in terms of speed of temperature rise, 

flashover point and eventual temperature peak. 

Definitions of fire resistance are met in the 

context of two criteria: 

Integrity: 

The time taken before failure of the wall 

system to satisfactorily prevent the passage 

of flames and hot gases in accordance with 

the test procedures laid down in this 

standard. 

Insulation: 

This must be non-combustible and restrict 

the transmittance of heat from the source of 

the fire to the unexposed face of the wall 

construction. 

Point of failure is deemed when the mean 

temperature on the unheated side of the 

construction exceeds 140°C above ambient 

or when the temperature of any surface point 

across the unexposed face reaches 180°C 

above the initial ambient. 

Tables A1 and A2 in Appendix A of Approved 

Document B (1992 edition) stipulate actual 

requirements which can vary from 1/2 hour 

integrity to 2 hours. Scottish regulation 

requirements can vary from 1/2 hour integrity 

to 4 hours. 

A comprehensive range of Corus Panels and 

Profiles wall cladding systems have been 

developed and certified/assessed to BS476 

Part 22. These offer a range of insulation 

performance from 15 minutes to the more 

stringent 1 hour requirement laid down for 

partitional/separating walls. 

These are shown in the System 

Illustrations/Specifications Section of this 

brochure. A quick reference table has also 

been included and can be found on the 

inside front cover. 

Updating Fire Requirements 

As a result of the ongoing programme for the 

revision of British standards it is inevitable 

that some will be withdrawn yet will still 

remain being cited by the Building Regulation 

Approved Documents. It is therefore 

recommended that designers review 

standards and approved documents for 

current status.

Acoustics 

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. 

Acoustic Systems 29

Introduction 

Acoustic 

Systems 

This section illustrates cladding assemblies designed to 

provide sound reduction and sound absorption. 

Both lining panel and structural liner tray systems are shown. 

The physical conditions under which the acoustic systems 

were tested are designed to match, as closely as possible, 

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.
