Western States “Western Lock ” PanelInstallation, Flashings & Shop Drawing Detail GuideNotes to Designer and InstallersThe details contained in this guide are provenindustry details and are intended to be used asa design aid and installation guide. It does notdepict all situations that may be encounteredon all projects. Modifications are theresponsibility of the designer/ owner/ installer.Consideration should be given for Fit forPurpose, Building use, Climate conditions suchas temperature, snow, wind, and moisture,Governing Building Codes, and Maintenance.It is highly recommended that all trims andflashings be of the same material as the panels(metal, gauge, finish) to ensure long termperformance and durability. Where possible,flashing edges should be hemmed to strengthenthe edge and protect the cut edge fromexposure.Framing and Substrates“Western Lock “ panels are used over all typeof substrates like Steel Decking, open purlins,spaced sheathing, and wood decking such asplywood. Most details in this guide are shownwith panels attached to Solid Decking.Note on UnderlaymentNot all conditions require an underlayment,However metal roofing is susceptible toCondensation and it is recommended that anappropriate Roofing underlayment be use on allwood substrates to protect the structure duringinstallation. For added protection from rain andsnow, it is recommended to use rubberized Iceand water shield on eaves, valleys, and areas ofroof penetrations.Technical Assistance Contact your WSDIsales or technical representative for anyadditional information or assistance.Slope RequirementsIt is recommended that “Western Lock ”panels have a minimum slope requirement of3:12 on all structures.Valley and Snow DesignValley design and dimension must be theproper width to accommodate high snow, rain,ice, and slope conditions. If possible, splices,penetrations, valleys, roof elevation changes,should be minimized in areas of high snow andice accumulations.Oil CanningOil canning is a condition common with flatmetal surfaces. This waviness is caused by steelmill tolerances, forming, variations in thestructures surfaces, and hardness of the steel.Measures are taken at the roll forming process,like profile design, steel gauge, correctiveleveling, to minimize the effects of oil canning.Oil Canning is a Characteristic of steel and cannot be eliminated totally and therefore is notreason for rejection of the panels.Job Site StorageWhile waiting to be installed on the job site,Storage of panels, trim crates, and flat sheetshould be sloped in order to allow for propermoisture run off. One end should be elevatedso as not to allow ponding of water on themetal surface. When using tarps for protection,proper ventilation should be provided toprevent condensation. Moisture orcondensation that is trapped inside a bundlecan lead to white rust on sheeting.ReferencesFor other installation techniques and details,The Sheet Metal and Air ConditioningContractors National Association Inc. (SMACNA)and NRCA manuals are great resource forworking with sheet metal.1

Western States Metal Roofing “Western Lock ” Standing Seam PanelInstallation, Flashings & Shop Drawing Detail GuideFastener SelectionNotes to Installers: Fastener Selection will vary depending on type and thickness of substrate. Design Calculations for clip spacing should be completed by the design engineer. The use of Butyl tape mastic, Butyl sealants and Curing Sealants is always recommendedto insure weather tight installation. Panels and flashings should never be installed in contact with dissimilar metals. Use only those flashings and accessories designed for use with this panel. Panel clip attachment screws must be long enough to fully penetrate through roof decksubstrate or penetrate solid lumber at least one inch. Exposed Trim Fasteners shouldhave sealing washers and becoated to provide protectionagainst corrosion.Screws must be properly drivento ensure holding strength andproper seal. (see diagram)Recommended drill speed is2000rpm. Improper setting ofdrill speed can lead to snappingof screw heads.Pre drilling of screw holes maybe necessary with heavy gaugemetals.2
