Choosing Doors for your Post Frame Building


Tips to help pick the perfect doors
Every post frame building needs at least one door to make it functional. In reality, most buildings require two or more to make it the most useable for you. But how do you choose the doors that would work best for your operation? After all, this is one of the most critical decisions when designing a building.

  • Key points to consider when choosing doors for your building:
  • What will you be using the doors for? Moving animals or equipment?
  • What’s the largest piece of equipment you would bring in?
  • How many different types of doors will you need?
  • What purpose will each serve? Where is the most logical flow of traffic to help direct where you would place the door(s)?
  • Do you need to drive your equipment straight through the building? If so, would you consider having doors on both ends?
  • Is the building insulated or cold storage? Will you potentially insulate it in the future?
  • What’s your budget?

Here’s a quick primer on the pros and cons of doors available for post frame buildings.

Walk-in Doors

Application
We suggest adding a smaller service door (walk-in) beside larger doors so that the large door does not have to be opened for routine activities.

Next Steps

1. Take measurements
The increasing size of today’s farm equipment requires increasingly larger door openings. Avoid unpleasant surprises by taking measurements of your equipment and carefully verify your needs.

2. Choose the characteristics you need
We’ve looked at the general characteristics of the different types of doors and where to best use them. Now it’s time to decide which characteristics will work best with your needs

3. Decide on placement of doors
We recommend placing large doors in the end walls of your post frame building for a couple of reasons:

  • snow doesn’t fall directly in front of them making it easier for you to enter and exit your building during the winter
  • ensures your building is structurally sound.

See how the design of the post frame machine shed at Prairie Rock Farms and placement of an overhead door on each end of the building has made moving large air seeders a breeze.

4. Ask for advice
While this is my last bullet, it really should be your starting point. We have designed and built hundreds of post frame buildings for a variety of uses. We’re more than happy to help customize your building with the best doors for your needs from the start.
