A pole barn is a structure that includes a roof supported by poles which run the perimeter of the structure. Walls are not needed to support the roof, so many of these structures are open-air designs. They can be used to house livestock, store heavy machinery, or even act as a garage or storage unit. If walls are necessary for added protection, pole barn siding can be used. This siding is generally inexpensive and lightweight, and it can be made from metal, wood, plastic, or other composite materials. Pole barn siding usually comes in sheets that are attached quickly and easily to the poles.
Metal pole barn siding is common because it is inexpensive and durable. Aluminum pole barn siding is lightweight and easy to install, though it is not always the most attractive option. Such siding will resist rust and corrosion, though it is not as resistant to impact as steel. Steel can be used as well, as long as it is galvanized to resist rust and corrosion. This will generally cost more than aluminum, though if it is impacted, the steel can be hammered back into shape fairly easily, while aluminum will have a tendency to crack.
Wood can also be used as pole barn siding, though this option tends to be quite a bit more expensive. Wood is perhaps the most attractive option, so if aesthetics are important, wood should be used. Any wood that is used as pole barn siding should be resistant to moisture damage as well as bug infestation; pressure-treated wood is commonly used, as are naturally weather-resistant woods such as cedar. Pine can also be used, but this wood is especially susceptible to moisture and bug damage, so maintenance will be required on a regular basis. Pine can also warp as it dries, and it is especially susceptible to cracking and splitting.
Plastic sheets of pole barn siding are also commonly used. These sheets are on par with metal in terms of price, and plastic is exceptionally resistant to water damage and bug infestation. Some lower-quality plastics can warp after constant exposure to sunlight, and the color of the plastic can fade after time as well, though some higher-end plastics are resistant to such damage. Plastic can crack if it is not installed correctly as well. Some types of plastic are also exceptionally resistant to damage from impacts.
