CARE AND HANDLINGSAFETYEach job site presents different hazards;therefore it is the responsibility of thecontractor to determine the safest wayto install Panel-Loc Plus based on therecommended instructions contained inthis guide and provide crew members withappropriate safety measures. If you must walkon a metal roof, take great care. Metal panelscan become slippery, so always wear shoeswith non-slip soles. Avoid working on metalroofs during wet conditions, when the panelscan become extremely slippery. Walking orstanding on a metal roof which does not havea plywood or other deck beneath it is notrecommended. However, if you must do so,always walk on the purlins, never between.OSHA safety regulationscomplied with at all times.shouldbeAlways wear heavy gloves when working with steel panels to avoid cuts fromsharp edges. If power cutting or drilling steel panels, always wear safety glasses toprevent eye injury from flying metal fragments.RECEIVING MATERIALSHANDLINGWhen unloading panels, extreme cautionmust be employed. Care needs to be usedwhen unloading panels with a forklift. Paneledges and underside paint may becomedamaged if the forklift driver does not usecaution.When unbundling the panels, never dragthem across the surface of one another. Thismay cause scratches across the underneathpanels. It is recommended that the panels be“rolled” off the top of the bundle to preventscratching. Panels should only be lifted andcarried by their sides. Panel edges are verysharp, therefore, safety equipment should beworn by all workers handling the material.STORAGEAll materials should be stored in a dry place,preferably under a roof. Panels and trim aresubject to staining and premature rustingwhen water sits upon, or becomes trappedbetween them. You may stand panels on endand fan them out at the bottom to provideair circulation and moisture run off. If spacedoes not allow for this, the panels should beseparated, blocked off the ground at least12 inches to allow air flow and stored at anincline to encourage drainage. The panelsshould then be covered in a manner to stillallow airflow through the sheets. Do not usea plastic cover, as this may cause the panelsto sweat or condensation to occur. Failure toproperly store panels and trim could resultin product failure that is not covered bymanufacturers warranty.CAUTIONRemove the protective strippable filmfrom trim prior to installation. The longerstrippable is left on the material, the harder itwill be to remove.FOOT TRAFFICCare of metal panels and flashings must beexercised throughout installation. Foot trafficcan cause distortion of panel and damage tofinish. Traffic over the installed roof must bekept to an absolute minimum.If walking on the roof panels is unavoidable,walk only on the minor ribs to minimizedamage.Strippable film on Textured panels and trim must be removed within 30 days ofmanufacture date. Strippable that is left on for more than 30 days may be hard to peel offand is not a reason for a refund or replacement from the manufacturer.C E N T R A L S TAT E S M A N U FA C T U R I N G , I N C .Effective 01/2022 Information subject to changeCAUTION5
CUTTING AND DRILLINGFIELD CUTTINGCentral States recommends tin snips/handshears, electric nibblers or a profile shear tocut metal panels and trim. All product surfacesshould be free of debris at all times. Installedsurfaces should be wiped clean at the endof each work period. Never cut panels overmetal surfaces. When cutting metal panels,always wear heavy gloves to avoid cuts fromsharp edges and safety glasses to prevent eyeinjury.Central States discourages the use of a powersaw that may generate hot metal shavings.Hot shavings can stick to the painted surface.If loose shavings are not removed from thepanel surface immediately they will begin tocorrode and shorten the life of the product.One method of preventing this problem is toflip the panel over when cutting and only cutone panel at a time. This allows you to brushshavings off of the back of the panel andhelps to avoid damaging the painted finish.Make sure that stacks of panels are away fromthe cutting area so shavings do not blowonto other panels.DRILLINGAlways use a cover sheet underneath yourpanel if you are predrilling fastener holes. Donot predrill more than one panel at a time.Predrilling multiple panels can cause shavingsto become embedded in interior panels.Brush away any loose shavings immediately.CAUTION Shavings created by saw cutting or drilling may cause the panel to rust and couldresult in product failure that is not covered by manufacturers warranty.FASTENINGFastener length will be determined by thesubstrate under the panel. Use a fastener withwasher and drive it into the flats of the panelat every purlin or 9" on center, based on thefastener spacings shown on page 7.CORRECTThe fastener's washer should be compressedfirmly against the metal, but not overdrivenwhich can cause leakage. If a fastener missesa purlin, remove it and use caulk or a stitchscrew to fill the hole.TOO LOOSEOVERDRIVENOverdriven fasteners can cause the washer to fail and leak or a dimpleCAUTION in the panel which can collect water and cause rust.6C E N T R A L S TAT E S M A N U FA C T U R I N G , I N C .Effective 01/2022 Information subject to change
FASTENER SPACINGFollow the suggested fastener patterns below for interior or panel termination.Screws may be placed in either the flat or the rib. In the overlap condition, avoid usingfasteners in the major rib as this may damage the siphon groove.Fastener pattern at panel termination (Eave, endlap, valley)9"9"Fastener pattern at interior of panel9"9"SIPHON GROOVEPanel-Loc Plus has two vertical edges,the overlap and the sidelap. The sidelapedge has a specific bend in the lastmajor rib, called a siphon groove. Whenthe overlap edge is installed on top ofthe sidelap edge, it creates an air gapthat prevents water from wicking underthe panel. Panels should be installedwith the overlap facing away from theprevailing wind.Do not damage thesiphon groove by using astitch screw on top of themajor rib or clog it withbutyl tape.SIPHON GROOVEOVERLAPSIDELAPPREVAILINGWINDSOVERLAPSIDELAPC E N T R A L S TAT E S M A N U FA C T U R I N G , I N C .Effective 01/2022 Information subject to change7
ROOF PREPARATIONPanel-Loc Plus can be installed over existing shingles,over solid decking or over purlins/open framing.It is the responsibility of the contractor to ensure asuitable substrate prior to the application of PanelLoc Plus. Substructures should be designed to meetall necessary code requirements. Green lumber isnot recommended as moisture can damage themetal panels and cause fasteners to back out.Distortion in the panel caused by an unevensubstrate, ripples, or laps in the vapor barrier,debris, protruding nails and staples, button capnails, etc., are not defects in the materials and arenot the responsibility of Central States. To minimizedistortions from an uneven substrate, use Retroeaseor 1x4 furring strips.2'EXISTING SHINGLES1. Make sure any existing decking is smooth, level and in good condition.Remove any damaged shingles or debris that might interfere with installation.2. Apply 30 lb. felt or synthetic underlayment using nails or staples.3. Apply 1x4 furring strips or Retroease horizontally, every 2' on center.These strips will act as purlin framing that you will fasten panels to.4. Check for roof squareness. Follow guidelines on page 10.5. Begin installation of trim and panels following guidelines on pages 12-13.CAUTION8Check local codes when installing metal roofing over existing shingles. It is notrecommended to install over more than 2 layers of shingles. Shingles may rotbetween layers due to trapped moisture, or substructure may fail due to weightof shingles and metal roof.C E N T R A L S TAT E S M A N U FA C T U R I N G , I N C .Effective 01/2022 Information subject to change
ROOF PREPARATIONSOLID DECKING1. Make sure decking is smooth, level and in good condition. Remove anydebris that might interfere with installation.2. Apply 30 lb. felt or synthetic underlayment using nails or staples.3. Check for roof squareness. Follow guidelines on page 10.4. Begin installation of trim and panels following guidelines on pages 12-13.OPEN FRAMINGPanel-Loc Plus can be install directly over purlins/wood framing. Maximum purlinspacing is 2'. This method should only be used for heated spaces if adequateprotection against condensation is used. Without this protection, the underside ofthe panel may collect condensation and drip into structure.1. Check for roof squareness. Follow guidelines on page 10.2. Begin installation of trim and panels following guidelines on pages 12-13.C E N T R A L S TAT E S M A N U FA C T U R I N G , I N C .Effective 01/2022 Information subject to change9
SUBSTRUCTURE SQUARENESSThe installer should check the roof deck forsquareness before installation. Panel distortionmay occur if not applied over properly aligned anduniform substructure. Several methods can beused to verify squareness of the structure for properinstallation of the panels.CAUTIONIf the structure is out of square, you can use the 3-4-5triangle method to create an alignment line to startyour first run of panels.Correct any squareness issues as early in the installation as possible. It might notappear to be a problem at the beginning, but if left uncorrected it will be verynoticeable in the end.RIDGEOVERVIEWThe main goal is to create a trianglewith sides that are 3', 4' and 5'. Whenthis is accomplished you know youhave a right angle at the eave torake and can create an alignmentline that is square.5'RAKE4'3'EAVERIDGESTEP 11.
