Pre-Engineered Metal Buildings vs Post Frame Construction

When it comes to constructing a commercial, industrial or agricultural building, two of the most popular options are pre-engineered metal buildings and post frame buildings. Both buildings are cost-effective options that are designed and manufactured to meet specific requirements, and they can be erected quickly and easily on-site. This makes them an attractive option for those who need to build a large structure in a short amount of time. The framing structure for both buildings is similar. Primary framing is provided by columns and rafters or trusses.

Both options have their own unique advantages and disadvantages, and the choice between the two depends on the specific needs and requirements of the project. In this blog, we will compare pre-engineered metal buildings and post frame buildings to help you make an informed decision.

Pre-engineered Metal Buildings

Pre-engineered metal buildings are composed of a steel frame, steel girts/purlins, and painted metal roof/wall panels.

Benefits

• Higher level of durability

  • Steel frame is able to withstand severe weather conditions and natural disasters

  • No risk of termite damage

• Larger spans and bays are available

  • Steel provides 200+ ft clear spans while wood trusses are typically limited to clear spans of 100 ft

• Incremental sizing

  • Post frame trusses are typically only manufactured in certain widths, limiting your ability to make a building the exact width needed

  • If needed, you could customize your building to be 86’ 9.5” wide

Post Frame Buildings

Post frame buildings, also known as pole barns, are constructed using treated wood posts that are driven or anchored into the ground. The posts and trusses provide the main structure of the building. Purlins and girts are composed of wood (often 2x4 or 2x6s). The roof/wall panels are the same

Benefits

• The use of wood in the roof and wall construction provides better insulation vs steel construction

• Interior build out can be easier since main structural components are made of wood, allowing use of traditional residential building components

Conclusion

When it comes to choosing between pre-engineered metal buildings and post frame buildings, it is important to consider your specific needs and requirements. If you are looking for a cost-effective and flexible option, a post frame building may be the best choice. However, if you are looking for a durable option, a pre-engineered metal building is the better choice. Ultimately, the choice between the two depends on your individual project requirements and the specific climate conditions in your area.
