METAL BUILDINGS WALL SHEETING INSTALLATION (Con't.)
STEP 3
Begin sheeting the steel buildings sidewalls first. Plan the lap
so that it is not visible from the front of the steel building.
Start first sheet at corners with center of high rib in line with
edge of steel buildings line as shown. See next page for center
line starting point for first sheet.
It is very important that you use a level to plumb the wall
sheets while holding them in place by hand. When plumb run the first
two screws through the girt to hold the sheet in place.
