Which Building Materials Are Included in Your Pole Barn Kit?

When investing in a pole barn kit, it's essential to know exactly what building materials are included. 

The building materials in your kit, from the lumber grade to the type of metal and trusses, play a crucial role in the durability and functionality of your new structure.

Let’s look at what you can expect to find in a typical 30’ x 48’ x 12’ pole barn kit.

1) Floor Plan

Pole Barn Kits_30x48x12Our in-house structural engineering team has carefully designed each floor plan to ensure proper building strength.

This blueprint shows optimal locations for overhead doors, walk doors, and windows. Of course, the walk doors and windows can be rearranged to better serve your needs.

However, the placement of overhead doors (on the end or side wall) must adhere to design specifications. The door headers are precisely engineered to support the load of the opening, which can vary depending on the location.

2) Laminated Columns

BG Supply Laminated ColumnsThe term “laminated column” refers to two or more layers of dimensional lumber that have been mechanically laminated with nails. This type of post is strong, stress-rated, and pressure-treated.

Laminated columns are highly resistant to bending, twisting, and warping. Furthermore, they have greater longevity than solid 6x6 posts. Each layer of lumber is permeated with wood preservatives and kiln-dried, which prevents rot. While solid 6x6 posts are partially treated, they’re prone to rotting from the inside out.

Our in-house truss plant manufactures 3-ply 2x6 laminated columns for post-frame material packages.

3) Fasteners

BG Supply Screw Fastener-1Next, your pole barn kit will include #10-15 WoodMAC HiLo Metal to Wood Fasteners, engineered for precision and durability. 

Featuring a 304 stainless steel capped hex washer head, this screw is resistant to red rust. The high hex washer design offers excellent driving stability, while the Type 17 milled point allows for quick and easy installation. Each screw has an assembled EPDM sealing washer, enhancing its weatherproofing power.

Backed by a lifetime warranty, the #10-15 WoodMAC™ HiLo Metal to Wood Fastener is guaranteed to provide long-term effectiveness.

4) Steel

BG Supply SteelBG Supply proudly partners with McElroy Metal to provide a Max-Rib II Galvalume Substrate with a Silicone Modified Polyester (SMP) paint system.

This metal panel is a 29-gauge, heat-treated, full-hard, and high-tensile with a minimum yield point of 80,000 pounds per square inch (psi).

Galvalume steel is glazed with aluminum and zinc coating using a continuous hot dip process.

The alloy mixture comprises 45% zinc and 55% aluminum for a stronger substrate. Galvalume outranks galvanized steel in terms of protection against corrosion.

Moreover, an SMP paint system combines polyester and silicone polymers. SMPs contain 30% or less silicone, enhancing chalk performance and retaining gloss.

McElroy Metal offers a 50-year warranty for galvalume substrates and a 30-year warranty for its SMP paint system. These product guarantees are unparalleled in the post-frame construction industry!

Editor’s Note: All metal panels, including the gable ends, are stacked in sequence (left to right), so customers do not waste time re-stacking on the job site.

5) Trusses

BG Supply Pole Barn Kit TrussEach pole barn truss is specially designed, engineered, and manufactured by our in-house team in Remington, Indiana. We utilize advanced computer-aided design and simulation software to ensure your roof system is robust and structurally sound according to ASCE 7 Standards.

Additionally, our pole barn trusses are made out of Southern Yellow Pine. This lumber species is durable and dense, making it an excellent choice for agricultural, commercial, and residential post-frame buildings. Nails and screws fasten and hold very well.

Generally, we use SYP #1 for truss webs and SYP MSR2400 for door headers and truss chords.

Editor’s Note: Our in-house truss manufacturing plant is regularly certified by a third-party inspection service to ensure quality fabrication.

6) Walk Doors

Steel walk doors are available in four styles and protect against the elements.

We recommend installing thermally broken walk doors. This built-in thermal barrier cuts heat gain in the summer and heat loss in the winter. 

With a thermal break and proper weather sealing, the advertised R-value of the walk door has more meaning.

7) Windows

BG Supply WindowsLastly, windows promote energy efficiency within your post-frame building by allowing natural light and producing passive solar heating.

BG Supply works with vendors to offer various window styles and sizes, including horizontal sliders and single-hung (grids or no grids). We recommend Low-E glass with Argon gas, which effectively controls temperature during the summer and winter.

Installing quality windows can add architectural detail and positive benefits to your new pole barn.

How Much Does a 30' x 48' x 12' Pole Barn Kit Cost?

BG Supply 30 x 48 x 12 Pole Barn Kit

Pole barn kit prices vary based on location, size, and customization options. A 30’ x 48’ x 12’ post-frame material package starts at $16,452.79 with potential increases for additional features and current building material costs.

When shopping around, you'll quickly notice that pole barn kit prices can vary widely. Not all post-frame material packages offer the same value, so how do you choose the right one? A smart approach is to start by understanding these three key cost factors when pricing a pole barn kit.

1) Quality of Building Materials

As mentioned above, product quality impacts the overall price of a post-frame material package. 

For instance, which lumber grade is being used? Which sheet metal gauge is included? Are you receiving laminated columns or solid posts? When asking yourself these questions, it's crucial to ensure you're comparing apples to apples and not apples to oranges.

Paying more upfront for premium building materials can save you money in the long run by avoiding costly pole barn repairs.

2) Pole Barn Size

Is a 30’ x 48’ x 12’ pole barn sufficient for your future needs? Will you need to adjust the height or size in five to ten years? 

Remember, increasing the dimensions of your post-frame building will result in a higher cost.

3) Location of the Post-Frame Building

The price of your pole barn kit also depends on your location. 

If you’re close to our retail locations, you can save money on freight costs by picking up your post-frame material package. Conversely, if your pole barn kit needs to be delivered, freight charges will be based on your location.
