Have you decided to build a pole barn on your property for storage? Then you want one that stands up to the elements and lasts as long as possible. So what is the best siding for pole barns? The two most common types are galvanized steel and Galvalume.
What Is Galvalume?
Galvalume is an alloy of 45 percent zinc and 55 percent aluminum. It looks similar to galvanized steel. However, its crystals are smaller and closer together, so it looks smoother.
How Galvalume Resists Damage
Galvalume has barrier corrosion resistance and heat resistance similar to aluminized material. It also has good bare edge galvanic protection and forming qualities like galvanized materials. As a result, it can resist damage from rust, the elements and fire.
Galvalume resists corrosion better than galvanized steel. However, it does not protect scratches and cut edges as well.
Coatings and Warranties
Manufacturers can add a polyvinylidene fluoride coating to Galvalume for stain and chemical resistance. This coating has a major effect on the length of the warranty. Most Galvalume and galvanized steel have a coating. Even so, Galvalume can also perform well without one.
Comparing the Best Siding for Pole Barns
Galvalume and galvanized steel both weigh 100 to 150 pounds per 100 square feet. Also, both contain about 35 percent recycled materials, and both cost about the same.
Use Around Concrete and Mortar
Concrete and mortar are highly alkaline. So do not use Galvalume on, in or around them, because that can lead to rapid corrosion. Instead, galvanized steel is a better choice around concrete and mortar.
Use Around Animals and Crops
Galvalume corrodes quickly around animal confinement areas and agricultural products. However, it can resist corrosion from industrial and marine environments. In addition, Galvalume offers excellent heat reflectivity. That can improve interior comfort and reduce energy needs.
Other Siding Options
In some cases, more conventional materials like aluminum or vinyl siding might also be the best siding for pole barns in your situation.
