What are Corrugated Panels?
Corrugated metal roofing is a metal sheet that is rolled and formed into metal panels. These panels are then attached to the roof with screws. Corrugated metal is an exposed fastener panel, meaning that each fastener is visible on the panel’s surface.
2.5″ corrugated panels are a popular choice for post-frame buildings such as horse barns, riding arenas, machine storages, sheds, and most other buildings for agricultural use. Our quality steel is made in the USA and is by far the most efficient and economical choice for most low-rise building applications.
Modern corrugated metal roofing panels are usually made out of galvanized steel. For roofing applications, a minimum slope of 3:12 is recommended. Primarily, they are implemented as metal roofing or wall systems composed of corrugated panels held in place by exposed screws / fasteners color-matched to the paint color of the metal panels. Often caulking is used at the overlap in between the panels for water tightness.
Corrugated panels are available in the “⅞” Corrugated” style. It is 32” of coverage, with a 0.875” rib height

Side Lap Procedure
Please see side lap detail. Pay careful attention that the uneven rib is over lapped by the even rib as shown in the side lap detail.
End Lap Procedure
When long panels are required. Tri-State Metal Roofing Supply recommends the customer to consider lapping the panels a minimum of 16” to insure proper drainage. Two strips of butyl sealant tape should be used at the end lap and fastened on the uphill side of the strips of butyl sealant tape.
Eave Detail Procedure
Tri-State Metal Roofing Supply recommends the use of an eave flashing with butyl sealant tape above and below the closure strip (inside) which will go between the underside of the roofing panel and on the top side of the flashing to avoid water infiltration.
Ridge Detail Procedure
The appropriate ridge cap is placed on top of the solid closure strips (outside) with butyl sealant tape above and below the closure fastened through each rib at 9” on center. A vented closure strip can also be used to provide adequate air flow in and out of your attic. A longer screw (2”‐2.5”) is recommended to be used to fasten the ridge. Each section of ridge cap needs to be overlapped a minimum of 12 inches.
Metal to Wood application‐ Tuff‐Rib panels should be fastened by a minimum #9 x 1.5” wood grip. Metal to Metal application‐ Tuff‐Rib panels should be fastened by a minimum #12 x 1” Tek screw
Tuff‐Rib panels used as siding are side lapped the same as in the roofing application. It is best to start a siding sheet at a large opening (i.e. sliding door, window, door etc.) so that the panels are square. Butyl sealant tape is not required for side lap application. However, butyl sealant tape is recommended where any closures are required.
Trimming And Cutting Steel Panels
Whether cutting with the profile (length‐wise) or across the profile (width‐wise), it is best to use a steel cutting blade or an abrasive, self consuming (carboundum) blade with an electric saw, hand tin snips or a nibbler. It is very important to cut panels one at a time with the finished side or panel facing down on wood blocks. Care should be taken to ensure that the hot metal particles and filings from the cutting do not become embedded in the panel.
Filings from screw cuttings must be cleaned off the panels after screws have been applied through the panel to avoid rust marks or “bleeding” on the panels. Store only in a dry place. Stack flat on blocks or racks to protect bottom panels. Failure to comply with the above procedures relieves Tri-State Metal Roofing Supply responsibility of damage to or deterioration of the finish and voids any paint or finish warranty.
