How to Install Corrugated Metal Walls

Metal siding can be an economical and attractive option in many buildings. It is not often used in houses, but is common in barns, sheds, farm and ranch outbuildings and many industrial structures. It is durable, inexpensive to install because it comes in large panels, can be very sturdy and is resistant to rot, decay and termites. It may be more common in roofing, but also can be used for siding. Corrugated panels are made of aluminum or galvanized steel and can be obtained with permanent coatings in a variety of colors.

Step 1

Measure the wall where corrugated metal panels will be installed. Panels come in 26- or 27 1/2-inch widths, depending on the size of the corrugation, and in 8-, 10-, 12- or 16-foot lengths. Measure the wall framing where panels will be fastened. Panels are designed to be fastened at 24-inch increments. Decide whether you want corrugations to be horizontal or vertical — either works, although a wall subject to a lot of moisture will drain better with vertical installation.

Step 2

Start at the bottom and side of a wall; hold a panel in place and fasten it with galvanized sheet metal screws through the metal into the wall framing. Put screws in the bottom first, hold the panel firmly in place and add screws to the top to secure it. Then add screws into wall framing every 10-12 inches.

Step 3

Overlap the next panel by one corrugated ridge and valley. Overlap from top to bottom. Overlap the length of panels by at least 4 inches whether installing horizontally or vertically. Cover the wall completely, cutting panels where needed to fit with tin snips or a metal saw. Finish the wall by installing sheet metal flashing at the top, bent at an angle to prevent water from getting in behind the metal panel. Where two metal walls meet, screw in a metal corner to join them.
