The next roof sheet is placed on the Roof Connectors with the female rib of the sheet over the male rib of the previous sheet. A wire is used as an alignment line to ensure that the roof sheets are straight laterally, parallel to the eave purlin. The side lap is temporarily locked in position at intervals by a hand seamer. As in Step 2, S-clips are then positioned over the male rib and fastened into position with M8 nuts and bolts.
