Corus Panels and Profiles offers the

widest range of Structural Roof

Decking manufactured in the UK, with

decks ranging from 19mm to 210mm

deep, in addition to a structural lining

tray the HL600/130. To provide still

more choice, we also offer a special

roof deck range manufactured by

Corus in continental Europe.

By definition, roof decking supports

the roof elements but does not provide

the weatherproofing layer. Where

metal profiles provide the

weatherproofing they are referred to

as roof sheeting or roof cladding.

Roof decking may be used to support

insulation and single ply membrane,

three ply felt, or asphalt. It can also be

used for long span built up metal

systems and for slates and tiles. The

decking can be used as a diaphragm

to replace in plane roof bracing or

when required the deck also provides

lateral restraint to the top flange of

support beams.

Corus Panels and Profiles Technical

Department offers an excellent

structural design service providing

diaphragm design for decks and full

support calculations for all profiles.

Full load tables are available from our

website or our technical department.

Developed to satisfy the designer’s needs for economy,aesthetics and structural performance.

Load/span figuresThe tables are based on a total ‘Dead & Super’ imposed load of1.50kN/m2, a line load of 1.50kN/m and a deflection limit of L/250.Where actual design loads exceed these, the spans must be reduced.Subject to satisfactory fixings, the decks will resist wind uplift to at leastthe value of 1.50kN/m2.

In some cases spans may be increased by using multi (3 or more)spans rather than double spans. Full load span tables may be obtainedfrom our website www.coruspanelsandprofiles.co.uk or from ourtechnical department.

Maximum cantilevers assume a 0.9kN point load on the end, with theadjacent span being the single span as shown in the table. The end ofthe cantilever must be stiffened with an angle flashing. Steel type istaken as galvanised at 280N/mm2 guaranteed minimum yield stress andcoated steel at 220N/mm2.

Metal decking may mark if subjected to extreme point or impact load.Where the sheet is required as an exposed soffit, a thicker sheet shouldbe considered if localised marking is not acceptable.

AcousticsCertain decks are available with perforated webs, as illustrated, toprovide acoustic absorption. The percentage open areas are highlightednext to the relevant profile, which relates to the standard patternillustrated below (except D159).

4.5mm holes at 6.3mm triangularcentres. Pattern open area 46%.

Other perforating patterns or fullyperforated deck may be available,please enquire if required.

Fire RatingAll non perforated deck sheets provide a fire rating of Class 1 to BS476:Part 7 and Class O in accordance with current Building Regulations.

CurvingSelf curving can induce stress marking in the sheet. The radius limitssuggested in the tables reduce the visible effect of this; however someperceptible distortion may occur.

for the use of profiled sheet for roof

and wall cladding on buildings. Part 1.

Fragility

Non-fragility requirements are

determined by ACR(M)001:2000 Test

For Fragility of Roofing Assemblies

(second edition) see next section.

Calculate loads in accordance with:

BS 6399 Part 2 :1995 Code of

Concentrated Load

Concentrated load is assumed to act

over a square with sides of 125mm.

BS 5950 : Part 6 considers that

concentrated load is equivalent to line

loading as follows.

Roof safety

5.1 ACR(M)001:2000 Test For Fragility of Roofing Assemblies (second addition)

ACR(M)001:2000 was produced by the Health and safety

executive (HSE), Metal Cladding and Roofing

Manufacturers Association (MCRMA), National Federation

of Roofing Contractors (NFRC), Association of Rooflight

Manufacturers (ARM), British Cladding Council (BCC),

Fibre-cement Manufacturers Association (FMCA), INFORM.

Summary of test method

Sheeting is fixed to a test rig specified in the document and

a drop test is conducted, which involves releasing a 45kg

sand bag from a height of 1.2m. The sand bag must impact

the sample:-

1. within 150mm of the centre of the test sample.

2. within 300mm of a support point, at least 150mm away

from the support.

3. within 150mm of the edge of the sheet, adjacent to the

underlap with the other sheet, at the weakest position.

Other test conditions specified in the document also have

to be met.

Corus Panels & Profiles carried out an extensive test

program consisting of 360 tests to show the following

results.

This data only applies to Corus Panels & Profiles products,

which must be fixed as indicated.

Summary of classificationFragileImpactor (sand bag) passes through assembly on first drop.

Class C non-fragile

Impactor is retained on the assembly for 5 minutes after

1st drop.

Class B non-fragile

Impactor is retained on the assembly for 5 minutes after

2nd drop in the same place as the 1st drop.

Class A non-fragile

On conclusion of the 2nd drop there is no significant

damage to the assembly.

Diaphragm analysis program• All the input data seen below must

be supplied by the building designer

• The analysis assumes that the

diaphragm area is rectangular

Benefits

• Removes visual clutter in the roof -

popular with architects

• Saves money by removing some of

the steel elements

To design, we need –

• Drawings, showing deck layout and

braced walls

• Line loads at diaphragm edges

Limitations

• Diaphragm area must be surrounded

by at least 3 braced walls

• Deck must be fixed to the structure

on all 4 edges of diaphragm area
