Single ply roofsSingle ply roofs are the most successful form of non-residentialflat roofing in the UK. Corus Panels and Profiles roof decksoffer the complete structural package with single plymembrane, for long and short span designs.

Green roofsThe UK's largest and greenestsustainable storage facility at AdnamsBrewery used Corus Panels and ProfilesD159 under a Sky-Garden Greenroof toreduce the visual impact of the buildingon the landscape and to regulatethe internal temperature."

Tiles and slate roofs Structural liner trays provide an excellentsupport system for traditional tiled andslate roofs. The tray's inherent strengthallows long sheet lengths to be used,requiring fewer supports and alsoenables the structure to be quicklyweatherproof. The tray can also offerexceptional acoustic performance whilstgiving an attractive internal flat soffit.

Structural roof deck profile range

Load/span figuresThe tables are based on a total ‘Dead & Super’ imposed loadof 1.50kN/m2, a line load of 2.00kN/m and a deflection limit ofL/200. The factor of safety used is 1.5. Where actual designloads exceed these, the spans must be reduced. Subject tosatisfactory fixings, the decks will resist wind uplift to at leastthe value of 1.50kN/m2, and a deflection limit of L/90.Full load span tables may be obtained from our website:www.coruspanelsandprofiles.co.uk or from our technical department.

Maximum cantilevers assume a 0.9kN point load on the end,with the adjacent span being the single span as shown in thetable. The end of the cantilever must be stiffened with an angle flashing. Steel type is taken as galvanised at 280N/mm2 guaranteed minimum yield stress and coated steel at 220N/mm2

Sheet lengths – extended end lapsSheet lengths in excess of 12 metres are not practical forinstallation on site and may also be subject to deliveryrestrictions. Extended end laps can be used to create a doublespan whilst keeping the deck length to a minimum. If a decklength in excess of 12 metres is nevertheless required, contactour Technical Department for assistance.

Point and impact loadsMetal decking may mark if subjected to extreme point orimpact load. Where the sheet is required as an exposed soffit,a thicker qauge should be considered if localised marking isnot acceptable.

CurvingSelf curving can induce stress marking in the sheet. The radiuslimits suggested in the tables reduce the visible effect of this;however some perceptible distortion may occur.

Rain noiseApproved Document E, 2004Amendment requires construction of newschool buildings to follow guidanceprovided by Building Bulletin 93. BB 93advises designers to consider the effectof impact noise from rain at an earlystage of the roof design in order tominimise disturbance within the building.

What constitutes a problem level of rainnoise is subjective. Roof systemsemploying a weatherproofing layer in fullcontact with insulation, supported by ametal deck are not usually problematic inpractice. However for more criticalapplications rain noise may be reducedby the selective specification of theinsulation system, and to a lesser extentthe membrane, the fixing system, andthe vapour control layer.

Rain generated impact soundtransmission is measured by a test toDraft International Standard ISO 140-18.

A tank positioned 3.5m above the testroof is filled with water and consistentlyrecharged. The perforated base area,height and flow rate are calibrated toensure a rainfall intensity of 0.67 Lmin/m³(40mm/h). Sound intensitymeasurements are taken below the roofconstruction in the frequency range of 50 Hz to 5000 Hz.

Indicative sound level test results on D600.7mm deck are between 52 - 60dB.

The sound intensity level measures theamount of sound being transmittedthrough the roof and therefore the lowerthis figure is, the better.

Further details, test reports and details ofother combinations are available fromRockwool Limited and Kingspan Insulation Limited respectively.

Technical information

Extended end lapsSheet lengths in excess of 12 metres arenot practical for installation on site andmay also be subject to delivery restrictions.Extended end laps can be used tocreate a double span whilst keeping thedeck length to a minimum. Load spandata for double spanning continuoussheet can conservatively be applied,provided these rules are followed.

The end lap must extend into 10% ofeach span and must be tail fixed bymeans of 5.5mm diameter self drillingsteel stitching screws connecting eachweb (not the flange) of the overlyingprofile, to the web of the underlyingprofile, one fixing in each web (2 perpitch or the sheet) at each end of theend lap. The web is the inclined upright

part of the profile (as opposed to thehorizontal flanges).

The deck is fixed to the support in thenormal way.

The web fixings must not be madethrough perforated sections of webs.

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

D210 requires alignment cleats to prevent profile spread

*Every other pitch is based on always starting with a fixing in the first pitch

of every sheet, and a profile pitch of 200mm or less.

**Side lap fixing is not essential where using a fully supported under lap,

otherwise it’s recommended to fix at 450mm centres.

General UseThe design and application of profiledroofing and cladding is covered by BS5427 : Part 1 : 1996 Code of practice forthe use of profiled sheet for roof and wallcladding on buildings. Part 1. Design.

StructuralStructural performance of steel sheetingis covered by BS 5950 : Part 6 : 1995Structural use of steelwork in building.Code of practice for design of lightgauge profiled steel sheeting. Diaphragmdesign is covered by BS 5950 : Part 9 :1994 Structural use of steelwork inbuilding. Code of practice for stressedskin design

FragilityNon-fragility requirements aredetermined by ACR(M)001:2000 Test ForFragility of Roofing Assemblies (secondedition) see next section.

LoadingCalculate loads in accordance with: BS 6399 Part 2 :1997 Code of Practicefor wind loads BS 6399 Part 3 :1988Code of Practice for imposed roof loads(including snow and snow drifting).

Concentrated LoadConcentrated load is assumed to actover a square with sides of 125mm. BS 5950 : Part 6 considers thatconcentrated load is equivalent to lineloading as follows.

Concentrated load Line load0.9 kN 1.5 kN/m

1.8 kN 3.0 kN/m

EurocodesAt the time of publishing this literature theabove British Standards are current andapplicable, however over time they arebeing replaced by Eurocodes, as follows.Each part has to be used with its NationalAnnex, which gives nationally determinedfactors.

Diaphragm actionFunction of diaphragm action• Transfers wind load from walls to brace

walls running perpendicular

• Replaces in plane roof bracing

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 andbraced walls

• Line loads at diaphragm edges

Limitations

• Diaphragm area must be surroundedby at least 3 braced walls

• Deck must be fixed to the structure onall 4 edges of diaphragm area

Roof safety5.1 ACR(M)001:2000 Test for fragility of roofing assemblies (second addition)

Summary of test method

Sheeting is fixed to a test rig specified inthe document and a drop test isconducted, which involves releasing a45kg 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, atleast 150mm away from the support.

3. within 150mm of the edge of thesheet, adjacent to the underlap withthe other sheet, at the weakestposition.

Other test conditions specified in thedocument also have to be met. Corus Panels & Profiles carried out anextensive test program consisting of 360 tests to show the following results.This data only applies to Corus Panels &Profiles products, which must be fixedas indicated.

Summary of classification

FragileImpactor (sand bag) passes throughassembly on first drop.

Class C non-fragileImpactor is retained on the assembly for5 minutes after 1st drop.

Class B non-fragileImpactor is retained on the assembly for5 minutes after 2nd drop in the sameplace as the 1st drop.

Class A non-fragileOn conclusion of the 2nd drop there is nosignificant damage to the assembly.
