A painted corrugated panel for porch ceiling.
Corrugated metal is a lightweight, tough, practical, weather-resistant material. It is used primarily for roofs and sides of buildings such as barns or sheds. It can be obtained in a variety of metals---galvanized steel, stainless steel, painted steel, aluminum---and in a variety of weights (thickness of metal). There also are many styles, denoted by differences in the "bumps" of ridge tops and the overall height of the material. The most common is 2 1/2 inch by 1/2 inch, used on barns, sheds and other structures. Some manufacturers offer perforated or lattice styles, with holes in the metal.
Instructions
1. Measure the ceiling where you want to install corrugated metal and calculate the square footage: width times length. Most corrugated panels are 27 1/2 inches wide. The standard length is 8 feet, but you can buy panels 10, 12 or even 20 feet long. Panels are light but flexible and unwieldy, and longer lengths can be especially hard to handle although they can reduce the number of seams in the ceiling. When you calculate how many panels to buy, allow for overlap, generally one full ridge or about 2 1/2 inches. Some panels have tabs---one panel slides into the tab of the next---which eliminates overlaps.
