Prolok 12" and 16" with Concealed Fastening System. The Prolok Panel with its 12 or 16 inch width shows great shadow lines to enhance the overall appearance of any building.


Determine which flashings need to be installed prior to roof panels (eave flashings).
1. Align the female edge of the first panel with the chalk line along the gable end. Allow the roof panel to overhang fascia minimum 1". The panel must be 1½" down from the ridge.
2. After the roof panel is properly aligned, screw down the roof panel on the female side; fasten down the panel at the nailing flange. Now install the gable flashings.
3. Snap the second panel at the seam. Work the seam together from the eave to the ridge. Do not work the seam from the middle to each end.
4. Fasten down the panel by screwing the flange through the slots. If the slots are not located on the strapping, screw through the flange using the slots as a guide.
5. Apply panels as shown.
6. Attach large closures at the top of the panel.
7. Fasten Z bar over the closures at the top of the panel.
Pre finished sheet steel building products, such as wall and roof cladding,liner sheet, flashing, and associated items, have experienced an enviable growth record during the past twenty years or so. Coil coated pre finished sheet steel in a variety of colours and paint systems has greatly enhanced the appearance of thousands of industrial, commercial, institutional, recreational, residential and farm buildings, providing an economical, durable and attractive alternative to traditional materials. As with all materials, a little care and maintenance pays off handsomely in terms of longevity and repair costs. The recommendations which follow have been learned at first hand and represent the collective industry experience with thin- film paint systems applied to metallic coated sheet steel by the coil coating process. In this publication the term "thin-film paint system" refers to a modified silicone polyester or a fluorocarbon type having a coating thickness about 25um.
When the guidelines listed below have been observed, thin-film paint systems have been used successfully for all types of environments other than severe industrial atmospheres which require special consideration. The guidelines are not intended for barrier coatings, laminates, and new formulations which have different characteristics than the thin-film paint systems on which these guidelines are predicated.
