A Comparison Between Post Frame & Steel Frame for a Pole Barn
Original Article Published May 19, 2020
When planning your next building project, choosing the right construction method is crucial. For many businesses and property owners, post frame buildings—commonly known as pole barns—and steel frame buildings are top choices. At Mansea Metal, we specialize in providing high-quality metal roofing, metal siding, and post frame materials, helping you create durable, long-lasting structures for commercial or personal use.
In this article, we'll break down the differences between post frame buildings and steel frame buildings, covering costs, design flexibility, materials, insulation, and more.
What Is a Post Frame Building?
A post frame building, or pole barn, uses large wooden posts embedded in the ground to support the structure. These posts, paired with engineered trusses and metal siding and roofing, create a durable and versatile building. Post frame buildings are widely used for commercial pole barns, agricultural storage, workshops, and other large-scale projects.
What Is a Steel Frame Building?
Steel frame buildings rely on steel columns and beams for structural support. These structures are pre-engineered for durability, energy efficiency, and code compliance. While strong, steel frame construction typically requires more materials and a reinforced concrete foundation compared to post frame buildings
Cost Comparison: Post Frame vs Steel Frame
One of the key advantages of post frame buildings is cost. Because post frame construction uses fewer specialized materials and simpler methods, it's generally more affordable than steel frame construction. Labor and installation costs are lower, and construction timelines are faster.
Steel frame buildings, while highly durable, come with higher upfront costs due to heavy materials, complex foundations, and increased labor requirements.
Design Flexibility
Post frame buildings are highly adaptable, offering a range of roof pitches and customizable layouts. This flexibility makes it easy to match or complement existing structures on your property.
Steel frame buildings, by comparison, have limited design options. Roof pitches and layouts are more constrained, which can impact the overall aesthetic or functionality of the building.
Foundation Requirements
Post frame buildings require a level site for construction—ground irregularities can easily be corrected, and no concrete foundation is mandatory. This simplicity reduces costs and construction time.
Steel frame buildings are heavier and require a reinforced concrete foundation, increasing overall project costs and complexity.
Materials Used
The primary difference between the two construction methods is materials:
- Post frame buildings: Wooden posts and trusses, combined with metal roofing and metal siding. Fewer materials per square foot make this option cost-efficient and environmentally friendly.
- Steel frame buildings: Steel panels for walls and roofing, pre-engineered for energy efficiency and strength. Steel buildings require more materials for the same building footprint.
At Mansea Metal, we supply only metal roofing and siding—no shingles—ensuring your pole barn or post frame building is durable and low-maintenance.
Remodeling and Insulation
Post frame buildings are easy to modify. Most remodeling projects require basic tools, and insulation is straightforward: wall cavities can hold up to six inches of fiberglass insulation, while attics can accommodate up to 14-inch batts.
Steel frame buildings often require welding for modifications, and insulation is compressed between roof purlins and wall girts, limiting efficiency and flexibility
Which Option Is Right for Your Project
Both post frame and steel frame buildings provide long-lasting structures, but your choice depends on your priorities:
- Post frame buildings are cost-effective, versatile, and energy-efficient. Perfect for commercial pole barns, storage, workshops, or agricultural applications.
- Steel frame buildings are ideal for projects requiring specialized engineering or compliance with stricter building codes.
