How the Current Lumber Crisis is Impacting Our Business

What Do I Need To Know About Post-Frame Buildings?

You may be thinking about constructing a new post-frame building yourself or with the help of a contractor, but there are a few things you need to know before you start the building process. 

Post-frame buildings use a load-bearing post which is designed to support the roof system, it’s not like the traditional 2x stud framing like you would find used on a house. You can design and construct your post-frame structure in many different ways, but there are some dos and don’ts that you should keep in mind. 

The Difference Between A Post-Frame Building & A Pole Barn

The term “Pole Barn” can often be used in place of “Post Frame”, but there is a distinction between the two that some mistake. Post-Frame buildings are often built where “Pole Barns” are not permitted or the area isn’t zoned for it. Post Frame buildings usually use square or rectangular posts, larger treated lumber, or laminated columns, whereas Pole Barns use round poles.

What Are Some Additional Items I May Need?

Lumber is the most important item, but pressure-treated lumber is the best to use. It’s primarily used for skirt boards and posts. It’s important to remember that any lumber within 18” from the ground should be treated with common preservatives like Alkaline Copper Quarternary, Chromated Copper Arsenate, or Copper Azole.

You’ll also need to invest in some fasteners, especially ones that are corrosive resistant. Stainless steel or hot-dipped zinc-coated galvanized steel fasteners are often used with treated lumber as they’re more durable and resistant. It’s best to use the same type of metal for fasteners as the metal siding and trim, keep in mind that aluminum fasteners should not be used with copper-based treated lumber.

One of the most important parts of a building is treated and solid posts or nail-laminated column. Post sizes are often 4×6, 6×6, 8×8, or as required by design, and our Burrow’s team can help you determine what size of a post you need. Treated wood cleats may be nailed at the bottom of the post, concrete collars, rebar rods, or other anchors to provide uplift resistance and help with stability. A post may also have embedded precast concrete piers or specially designed wood to concrete steel brackets as an alternative to installing the wood post.

Another important factor in your post-frame building is having the right trusses, and having them spaced right and attached directly to the post. The trusses can be spaced the same as the post and directly to it, or they can be spaced differently and attached to a truss carrier beam that is between the post. It’s all based on preference and what is right for the building. If you’re opting for your trusses to be attached to a carrier or top girt, there is some other important information to take into consideration. The girt acts as a beam when in a weight-bearing case. The truss carrier is the highest girt from ground level.

At Burrow’s, we offer a variety of colors and ribbed patterns for siding. You have two choices for siding, corrugated galvanized steel(unpainted) or sheathing(OSB or plywood) and there are benefits for both. Corrugated galvanized steel is an eco-friendly choice, however, it’s not as durable as painted metals. Sheathing can be applied over the girts and other sidings like vinyl, stucco, stone veneer, lap, panel, wood, etc. Painted ribbed steel roofing is the most common covering for commercial and industrial buildings.
