TYPES OF CORRUGATED ROOFING SHEETS

There are several different shapes and sizes of corrugated metal. The design on your roof will determine the type to choose. Today a St. Charles Basement Finishing expert will help us understand some types. These are some of the commonly used sizes and shapes of corrugated roofing materials.

Type B Wide Rib

The shape of Wide Ribe or Type B corrugated metal is a strong choice because it has the capacity to carry load. This is why it is the most widely chosen style for industrial metal roofing. It can be made of galvanized steel, aluminum, painted steel or stainless steel. 36″ is the standard sheet width. It is especially good in cases where rigid insulation is needed on top of the roof deck because the wide rib of type B allows for a narrow top opening. Always remember to allow for overlaps at the support points when figuring out coverage for type B wide rib.

Type F Intermediate Rib

This is known as an Intermediate Rib due to its spacing that is not as wide as that of Type B. Intermediate rib is an older type of corrugated metal but it’s still used in specific applications. It is particularly serviceable for roofs that needs nest with an existing Type F roof. This type can also be found in painted or galvanized steel, aluminum or stainless steel and the width of a standard sheet is 36″.

Type F corrugated metal

2 1/2″ Rib or type F is much more advanced than the older type of 24GA 2 1/2 inches Corrugated metal. Type F has an improved carrying capabilities than the older type. It is often found in 30″ sheets.

N DECK CORRUGATED METAL

Also known as Thermal wall panels, they are firm and have a great load-carrying capability. It is best used when you are not using rigid insulation. N DECK can be found in aluminum, stainless steel, fiberglass and coated steel varieties. They are in wide flute profile and this makes it as attractive as a siding product for a roofing panel.

4″ Rib or THERMAL WALL CORRUGATED

They are readily available and easily recognizable but they are mostly used for siding. Thermal wall corrugated is not usually recommended for roofing applications.

R Panel or SEVEN EIGHTHS PANEL

R panel has a wide and deep profile that is very strong. It can be found as R panels in both roofing and siding applications.
