Differences Between Pole Barns Vs. Steel Span Barns

Design

• Pole barns are distinguished by a frame constructed of vertical posts connected to the roof trusses. In addition, pole barns have additional structural elements including wall girts, wall headers, and roof purlins to support the roof and siding. Many of the primary elements of pole barns are constructed of wood. In comparison, while steel barns have a similar construction in the connection of the walls to the roof, there are no supportive posts in the center of the structure. In addition, steel span barns are comprised entirely of steel including the siding and roof.

Cost

• Due to the easy construction and the use of wood as a primary material, pole barns are considered to be one of the cheapest barns to erect. When considering a smaller structure, pole barns are more cost effective than steel span barns. However, in the long-term steel span barns offer more economical considerations than their wooden counterparts. Unlike wood pole barns which will warp and be vulnerable to termite infestation or fire, steel span barns have more longevity. In addition, steel span barns will sometimes qualify property owner for savings on insurance as compared to the wooden pole barn.

Durability

• In relation to structural design, both pole and steel span barns are equal in terms of durability. However, due to the materials commonly used in construction of the barns steel-span barns last longer and hold up to the elements better than pole barns. Fire, termites, and inclement weather can all destroy a pole barn but the steel span barn is designed to withstand such assaults with minimal repair and maintenance.

Intended Use and Location

• When constructing a barn, the intended use for the structure plays a major role in choosing between the pole and steel span designs. For uses which need additional floor space as well as height clearance, steel span barns are better suited. On the other hand, pole barns are suitable for smaller structures such as those for storing materials and housing a small number of animals. Location is equally important. If the space where the barn is to be constructed has a smaller area, pole barns offer an economical choice. However, farms located in regions with termite problems may wish to choose a steel span barn to avoid early replacement and additional maintenance or repair costs.
