FBi vs Greiner Buildings: 7 Key Differences to Look For


1) Customer Service

FBi Buildings


From the initial inquiry to the final call with your Project Manager (PM), FBi ensures that you’re aware of every step involved with your post frame building.

Each customer is assigned their own Project Sales Consultant (PSC) that lives in their area.

Currently, FBi has 17 PSCs spread throughout Indiana, Illinois, Eastern Iowa, and Southern Michigan covering their designated territories. 

This arrangement allows your PSC to discuss your building needs in person, walk the property, and identify an ideal location for a new pole barn.

Once the contract is finalized, and construction is ready to start, you’ll be introduced to your Project Manager. They’ll schedule crews, review building changes, handle payments, and answer questions.

FBi’s Project Management team will outline your post frame project into four construction phases:

  • Processing: An overview of your building project from the signed purchase agreement to the down payment. FBi will go over site preparation, permitting, and give you an approximate start date.

  • Design and Permitting: FBi will follow up with you regarding your building permits and site prep updates. Your PM will review drawings and confirm the expected start date.

  • Pre-Mobilization: Your PM will verify the site prep via inspection. If approved, the construction crews and material delivery will be scheduled.

  • Construction: The final phase details the main milestones that'll happen during or after construction.

Greiner Buildings

Greiner’s customer service approach is slightly different. Instead of having an appointed PSC and PM, you’ll have one point-of-contact throughout the entire building process.

Similar to FBi, you can create your dream pole barn using their state-of-the-art 3D design tool

From there, Greiner will provide Stamped Engineer Plans (SEPs) to the customer and contractor. These drawings are often required by the International Building Code (IBC).

Moreover, they’ll submit floor plans, request quotes, hire, and manage all subcontractors needed for your post frame project. Common trades include:

This handy service takes the load off of customers’ shoulders and provides peace of mind.

Who has the best customer service?

Both companies offer assistance every step of the way but in different capacities.

FBi has assembled a larger team (e.g., sales, design, engineering, project management, and construction crews) to handle a high volume of detailed building projects. Personalization and timeliness are essential.

While one point-of-contact may sound appealing, you may run into delays as your salesperson juggles multiple roles. 

However, you cannot deny the added convenience of Greiner’s turn-key building services. It sets them apart from the competition.

2) Service Areas

Kenny Sales

FBi Buildings

FBi is a family-owned post frame construction company that started in 1958. Their corporate headquarters is located in Remington, Indiana. During their 60+ years, they’ve been known as the preferred post frame builder in the Midwest.

As mentioned above, their service area is limited to Indiana, Illinois, Eastern Iowa, and Southern Michigan.

Do you have a unique building project outside of their territory? They’ll pursue other options to see if it’s feasible for them to be your post frame builder.

Greiner Buildings

Greiner is a family-owned and operated construction company from Washington, Iowa. 

In the 1980s, founder Tom Greiner worked as a subcontractor for Lester and Wick Buildings.

Since then, Greiner has expanded to a full-fledged post frame builder serving select counties in Illinois, Iowa, and Wisconsin. 

Their corporate headquarters is located in Washington (IA) with satellite offices in Des Moines (IA), Kewanee (IL), and Minonk (IL).

Who has the best service areas?

FBi easily wins this category. With 140+ counties in four different states, their coverage can’t be beaten by Greiner Buildings.

3) Pole Barn Materials


Steel Panels_FBi BuildingsFBi Buildings

FBi’s metal panels are 29-gauge, heat-treated, full-hard, high-tensile steel with a minimum yield point of 80,000 PSI (pounds per square inch). That’s 60% to 78% higher than what’s commonly used.

A higher yield contributes to overall steel strength and improves the structural integrity of your pole barn by providing greater resistance to impact damage.

Their post frame buildings feature galvalume steel (roof and walls) coated with aluminum-zinc alloy by a continuous hot-dip process. This coating consists of 55% aluminum and 45% zinc, with a small silicon dose for fighting corrosive elements.

Depending on your pole barn colors, FBi will also use galvanized steel panels on their walls. Unlike galvalume, galvanized metal is subject to corrosion once the coating wears off.

Greiner Buildings

Greiner works with the same metal manufacturer as FBi to install 29-gauge/80,000 PSI high-tensile steel.

Who has the best steel?

Both construction companies are equal when it comes to the type of steel being used. Therefore, this section is a tie between FBi and Greiner.

FBi vs Greiner_Tie



FBi Buildings

The type of wood that FBi uses is dependent on the building design.

For example, if you’re interested in a cold storage building with large clear-span trusses, then FBi will use Machine Stress-Rated (MSR) lumber. Each piece of MSR lumber is tested for stiffness and strength before installation.

Furthermore, FBi uses #1 Southern Yellow Pine (SYP) lumber for post frame projects that require smaller trusses.

Greiner Buildings

Greiner’s wood selection process is similar to FBi’s. Every Greiner post frame building features Rigidply Rafters’ Glu-Lam posts (made out of #1 SYP) and MSR lumber.


Who has the best wood?

This category results in a tie. Both construction companies use #1 SYP and MSR lumber. These wood choices are touted for their strength, durability, and adaptability.

FBi vs Greiner_Tie


FBi Buildings_Screws_vs_Nails_Post_Frame_BuildingFBi Buildings

FBi uses a stainless steel capped, self-sealing screw. The screw fasteners encapsulate the sealing washer to protect it from the elements and improve aesthetics. 

The washer maintains its seal and is more reliable than commonly used neoprene; thus, offering superior heat, cold, weather, and ozone resistance.


Greiner Buildings

Greiner uses a zinc-coated hex head screw. Unfortunately, this standard screw doesn’t include an umbrella, which protects the washer from deterioration.


Who has the best screws?

FBi is the better choice because all of their screws are stainless steel. Each screw head forms an “umbrella.” Without this extra defense layer, your pole barn is more susceptible to leaks and rust.

FBi Buildings
Trusses for Snow Load Blog-1

FBi’s trusses are manufactured by their in-house truss plant and engineered specifically for your pole barn.

Their truss plant is regularly certified by a third-party inspection service (e.g., Truss Plant Institute) to ensure the quality fabrication of all trusses.

The lumber used to build the trusses are joined with heavy-duty steel plates.

FBi’s trusses are interlocked – not just attached – to the laminated columns with structural screws. It provides the same strength as bolts, but for less money.

Moreover, FBi is the only post frame builder to screw roof purlins onto the trusses. Testing has proved that screws provide greater uplift resistance than nails.

Typically, purlins are spaced no more than 24’’ on center. The spacing and orientation depend on how far apart the trusses are spaced.


Greiner Buildings

Greiner’s trusses are manufactured by a local business with a “solid reputation in the post frame industry.” 

This business uses higher standards (i.e., lumber grade and strength of gusset plates) required by local codes. As a result, their trusses can withstand heavier snow and wind loads.


Who has the best trusses?

FBi wins this category because of their in-house truss plant and quality control. FBi trusses are gently moved and handled fewer times, resulting in greater structural integrity.

Not to mention, their screwed-on purlins are a game-changer in the post frame industry. This fastener is less likely to be uplifted by forces, reducing the chances of rolled purlins and roof failure.

Paint Comparison_FBi BuildingsFBi Buildings

FBi’s roof and wall panels are finished with the Kynar 500 paint system.

This type of paint isn’t wet-dropped or sprayed-on, but baked-on for excellent resistance to fading, chalking, or corrosion. Their panels are known to maintain their vibrant color for 40+ years.

Do you need help picking a color scheme? Check out these tips for selecting the perfect pole barn color combination.


Greiner Buildings

Greiner’s steel panels are also painted with Kynar 500.

This coating material reduces urban energy, which is trapped solar energy that radiates back into the atmosphere. It can cause loss of vegetation and higher temperatures during the summer months.

The final result is a durable structure that withstands abrasion, ultraviolet radiation, extreme weather, chemicals, and solvents.

This category results in a tie between FBi and Greiner as they both finish their steel panels with the Kynar 500 paint system.

FBi vs Greiner_Tie


FBi Buildings

There are two types of ground contact when pricing your pole barn columns: Laminated Posts and Perma-Columns.

Similar to their trusses, FBi creates their laminated posts in-house. These columns have greater longevity than solid posts. Each layer of lumber is completely permeated with wood preservative and kiln-dried. It prevents rot and termite damage.

But not all column treatments are equal. FBi uses columns that are treated with 0.80 lb./cu. ft. of Chromated Copper Arsenate (CCA) wood preservative. That’s 33% more than industry standards, which you’ll find at hardware stores and lumber yards.

Alternatively, you can opt for Perma-Columns, which are precast concrete columns sized to fit any laminated or solid post. 

This solution is guaranteed to withstand insect damage, decay, and rotting. No wood goes into the ground.

Using 10,000 PSI precast concrete, Perma-Columns are 3x stronger than standard concrete. Then, the columns are reinforced with 60,000 PSI rebar welded to a ¼’’ steel bracket.

Furthermore, Perma-Columns include microfibers to add shock resistance and durability. Microsilica enhances compressive strength and erosion resistance. 

The corrosion inhibitor protects the rebar reinforcement and brackets from rusting. A final admixture is added for freeze and thaw protection.


Greiner Buildings

Glu-Lam LumberGreiner uses Glu-Lam posts made out of #1 SYP lumber. The columns are finger-jointed and won’t separate like its adhesive or nailed counterparts. 

Standard Glu-Lam posts are treated with 0.60 lb./cu. ft. CCA and kiln-dried before lamination. Again, these treatments minimize decay and warping, respectively.

Additionally, Greiner offers Post Saver Sleeves with Notch Design. This thermoplastic barrier protects columns from insect and moisture damage.

The laminated posts are double layer wrapped in Bitumen and Polyethylene with a factory applied heat seal.

Bitumen is a wood coating that’s been used for 1,200+ years. Polyethylene is a waterproof membrane that’s been used for 50+ years.

Each column has uplift restraint notches on end. This system, when used with concrete, resists post-withdrawal caused by high winds.

Post Saver Sleeves with Notch Design are non-toxic and environmentally-friendly.


Who has the best columns?

While both construction companies use laminated posts, FBi’s Perma-Columns is a more sustainable option than Greiner’s Post Saver Sleeve with Notch Design.

The Post Saver Notch Design’s uplift capacity doesn’t compare to the Perma-Column’s steel anchor. FBi’s concrete column is much heavier, further resisting uplift loads. In fact, Perma-Columns add 15% to 30% more deadweight (depending on the building size).

The 10,000 PSI concrete and steel reinforcements have a greater capacity than wood in terms of resisting bending forces at ground level. This area happens to be one of the highest wind pressure points within a post frame building. Added stress on a standard post causes fatigue, affecting building longevity.

In freezing weather, Bitumen becomes brittle and will most likely crack. The black material is an active ingredient in asphalt. Paved roads tend to crumble during the winter freeze and thaw cycle. 

This scenario can be applied to Post Saver Sleeves. Their decay zone is the same as the frost zone in Midwestern winters.

Lastly, smooth concrete is more aesthetically pleasing than tarred columns. It blends in well with a concrete or gravel floor. Whereas, some customers may view Post Saver Sleeves as an eyesore.

Sliding Doors

Step_Saver_LatchFBi’s EasyMotion sliding door was introduced to the market in 2010. One of the perks included with this door option is the StepSaver Latch, which will save you time and energy.

No more running around to the walk-in door to disengage cam latches and snugger chains. You can get inside your building in less time. Just turn the key and grab the handle. It’s that simple!

The EasyMotion door features the Posi-Guide Track. It’s an exclusive weatherproof system that ensures your sliding door opens and closes smoothly all year round.

The guide doesn’t collect rain, ice, snow, or debris (i.e., birds’ nest and leaves). A unique low-friction polymer roller is protected behind and underneath the track. This interlocking system keeps the door snug to the building.

FBi offers the following center guide options for your sliding door:

  • Wood center door stub
  • Concrete center door stub (wet or dry)
  • Concrete apron approach (wet or dry)
Overhead Doors

Overhead doors aren’t a standard feature with FBi pole barns. If you want to install an overhead door, FBi will work directly with their preferred vendors to get the style and size needed.

FBi’s engineers will carefully evaluate the entire building system and specify the necessary foundation, column, and header sizes needed to carry out the anticipated loads for each door.


Greiner Buildings
Sliding Doors

Greiner’s sliding doors use a metal roller and track system. They utilize a unique powder-coated framing system. Often, Greiner uses steel girts for heavy-duty doors that can slide straight with less friction.

Sliding doors can be single or split units. They’ve placed doors up to 40’ wide and 20’ tall.

Overhead Doors

Greiner installs insulated or non-insulated overhead doors for commercial businesses and residential dwellings. They offer a wide variety of colors, features, and sizes.

The maximum door width is approximately 32’ (depending on the overhead model). They require at least 2’ headroom to operate, which could be considered a drawback.

For farm shops, you can opt to install a hydraulic door. Greiner uses the same insulation in the door as your pole barn interior – no R-value loss! A tight seal lowers heat conduction. No additional headroom is needed. Widths up to 60’ can be installed.

If you like the idea of hydraulics, but you’re on a budget, Greiner can put in a bi-fold door.


Who has the best doors?

For sliding doors, FBi separates themselves apart from Greiner with their Posi-Guide Track.

Again, this system sits off the ground, eliminating door jambs caused by debris. The door track is rounded and self-cleaning (no oil needed). It’ll operate smoothly year after year.

Conversely, Greiner uses standard sliding door metal rollers. This component can rust or become weak. Their door track is exposed, which can collect debris and cause damage. As a result, you may run into issues with opening and closing your sliding door.

If you prefer to use overhead doors, both companies can find the style and size needed. Greiner gets a nod for performing their own installation.

4) Delivery


FBi Buildings


On the first day of construction, your building materials will be delivered on-site. FBi doesn’t prefer to deliver materials beforehand and have them sit out in the elements until construction crews show up.

The building size will determine the type of equipment needed. Usually, FBi brings the following machinery to a job-site:

  • A semi for material and delivery
  • Gradall telehandler
  • Crew truck and trailer
  • Skid steer (if applicable)
  • Crane (if applicable)

Company-employed drivers deliver materials straight from their own lumber yard.


Greiner Buildings

Similar to FBi, Greiner delivers their building materials to the job-site.


Who has the best delivery?

This category comes out to a tie as both companies will deliver your building components to the construction site.

5) Construction


FBi Buildings


FBi’s average crewmen have been employed for over 13 years. Experienced men make fewer mistakes, giving you a higher quality post frame building. 

FBi has a Crew Management team of construction veterans who oversee/support foremen and their workers.

They also have rigorous SafeStart safety training and Core 54 (apprentice carpenter training) programs that all crews have to complete. 

In fact, FBi’s safety program has won the NFBA’s Gold and Platinum Level Achievement, as well as the Gail Miller Distinguished Safety Award. They’ve also won multiple NFBA Crew Foreman of the Year awards.


Greiner Buildings

Similar to FBi, Greiner’s construction crews are company-employed. They hire experienced workers and continually support them through training seminars on industry standards.

Their safety program has won the NFBA’s Gold and Platinum Level Achievement Award for “improving job-site safety through the development, implementation, and enforcement of a safety program.”


Who has the best construction?

Both post frame companies invest in their own construction crews, but the advantage goes to FBi. 

They have tenure experience between their field workers and Crew Management teams. Their resources, coupled with direct accountability, is the best way to ensure quality performance.

6) Warranty


FBi Buildings

Pole_Barn_Warranty_Columns_Roof_StructureA pole barn warranty is a written promise to stand behind a certain product or service. All warranties are limited, and there isn’t a standard one in the post frame industry. With that being said, you don’t want to skim through them.

The following components are covered under FBi’s warranty:

  • Columns (Lifetime)
  • Roof Structure (20 years)
  • Red Rust (15 years)
  • Paint (40 years)
  • Gloss Loss (5 years)
  • Roof Leaks (5 years)
  • Sliding Doors (Lifetime)

Greiner Buildings

After researching Greiner’s website, the only listed warranties cover paint (40 years) and craftsmanship (lifetime). For more information, you’ll need to call or email their office.


Who has the best warranty?

FBi wins this category for having a more comprehensive list of warrantied features made available to the public.

7) Cost


FBi Buildings

Horse Barns_FBi BuildingsFBi is well aware that they aren’t the cheapest post frame builder in the industry, but they’re not the most expensive.

A standard pole barn shell can cost anywhere from $15 to $45 per square foot. Now, you’re probably asking yourself, “Why is there such a big difference in price per square foot?” Here’s why…

The following factors will determine if your pole barn is leaning towards the low/high side of the cost spectrum:

  • Total square feet
  • Type of features (e.g., overhangs, windows, walk-in doors, steel liner packages, etc.)
  • Current nature of the commodities market (e.g., the price of lumber and steel)

For example, adding a porch, cupolas, and numerous doors will push you closer to the $45 per square foot. If you want a basic 30’ x 40’ without the bells and whistles, you’ll pay closer to the $15 per square foot.


Greiner Buildings

Greiner prides themselves on fast and free estimates. They calculate pole barn cost on location, square footage, and finishing features.


Who has the best cost?

Typically, Greiner Buildings is cheaper than FBi in terms of raw cost. Again, multiple factors go into pricing a pole barn. However, if you’re interested in turn-key construction, Greiner may be the better (albeit more expensive) option.
