Use And Care Manual
Screwing of Steel Panels
Roof Sheets -Use 2" Wood Grip screws on rib top or 1" screws in the at.
Peak & Eave of roof sheets -Use 1" Wood Grip screws installed in the at surface
Wall sheets -Use 1" Wood Grip screws installed in the at surface
Note: Screw lengths may need to be adjusted.
Note: If an alternative fastening method is used, then the material list may have to be altered for
proper fastener lengths.
Fastener Specications:
Roof: Screws can be installed on top of the rib or in the at surface of the panel between the ribs.
Wall: Screws can be installed on top of the rib or in the at surface between ribs.
Installing Roof Steel
Note: Install optional Eave Trim before roof steel is installed.
Note: Install optional inside closure strips before placing each
roof panel. Be careful not to stretch the closure strips.
Nail a temporary 2×4 block on the outside of each end truss
extending 4" to 6" beyond the heel of the truss on both ends.
The length that you extend the 2×4 will determine the
overhang length.
Run a mason line the full length of the building between these
blocks. This mason line determines the length of the eave.
Cut the rst rib off leaving ¼" of rib on the rst roof sheet
of roof steel. Lay down the rst roof steel panel, squaring it with
the mason line. The roof panels are installed similar to the wall
panels in layout.
At the top and bottom of the panels use 1½” fasteners on both
sides of each rib, for the length of the building.
All intermediate fasteners can be put on the rib or in the
at when using screws.
Tape and lap sealants are required on lap joints when the roof
slope is less than 3/12 as per IBC 1507.4
