7/8 Exposed Fastener Corrugate Panel

About this product

The 7/8″ corrugated panel uses the same repeating rounded wave as classic corrugated metal, but with a deeper corrugation. That extra depth makes the sheet stiffer than 1/2″ corrugated, so it is a common pick for roofs and walls on barns, equipment buildings, garages, commercial siding and residential accent work where the corrugated look is wanted on a larger scale.

Like every exposed fastener system, it goes on without clips. Sheets lap at the sides and ends, and screws with sealing washers pass through the panel face into the purlins, framing or deck. That keeps installation quick and the accessory list short: no clip layout, no seaming, and fewer special tools than a standing seam roof.

The trade-off is that every screw is a penetration. Roof slope matters, because water on a low-pitch roof stays in contact with the washers longer. Check the panel maker’s minimum slope and screw pattern for the profile before you lay out the job, set washers snug rather than crushed, and plan to re-check screws during roof maintenance.

For a weathertight job, run Butyl Tape in the laps, close the eave and ridge, and seal flashings with Geocel 2300 or Geocel Phantom. Trim can be bent from Steel Coil on a Van Mark brake, and Malco aviation snips handle field cuts. Tell us the color, gauge and cut lengths you need and we will confirm what can be supplied.
