Podcast on Buying I-Beam Steel Buildings the Smart Way!

It is Different Here

Factory Steel Overstock was founded by a 35-year veteran of steel building and insulation who witnessed the industry’s pervasive unfair selling dynamics firsthand. Recognizing that the average consumer lacked the specialized knowledge or buying leverage, he changed the game, creating a business model rooted in transparency, fairness, and customer empowerment.

In an industry full of hidden fees, vague quotes, and confusing markups, he chose a different path—one guided by values. His company transparently lists prices! While many companies conceal their pricing until they’ve got you on the phone, his company believes in being upfront from the start—which builds trust.


Because of his unwavering commitment to fair pricing, Factory Steel Overstock’s growth has been fueled entirely by repeat customers, referrals, and organic search traffic—without spending a single dollar on advertising. Since 2013, the company has maintained an A+ rating with the Better Business Bureau and consistently earned 5-star reviews. This track record demonstrates that Factory Steel Overstock isn’t just offering a better way to buy insulation—it’s setting the standard for how the industry should operate.

One supplier even asked us to remove our pricing from our site. That tells you everything you need to know.
We didn’t flinch—and we won’t.
Our loyalty starts and ends with the public!” – John Barber

A Better Way to Buy Fiberglass, Reflective Insulation, and Metal Buildings

Imagine you’re in the market for fiberglass, reflective insulation, or metal buildings. The traditional way to proceed is to approach different outlets and ask for a quote. Then, you patiently wait for all your quote requests to return, hoping at least one price will excite you.

But consider this:  What if randomly requesting quotes from traditional outlets is the problem? What if the quotes that come back are higher than expected? What if the materials quoted are slightly different on each returned quote, making it difficult to compare them accurately? In such a scenario, what should one do?”

Now, could you consider choosing a different starting process? Instead of depending on traditional outlets to give you their quoted price, you calculate the wholesale delivered price online, verify the savings, and then purchase for a low flat brokerage fee.

With Factory Steel Overstock, you buy from an independent broker that has maintained an A+ BBB grade and 5-star rating since its inception. Think of it like this: Factory Steel Overstock helps you buy something for less than you can buy it on your own. You pay the certified supplier directly and pay FSO for the savings provided. It is a risk-free savings program. You pay nothing until you see the savings!

Why Don’t Traditional Companies Share Their Actual Cost?

Have you ever wondered why traditional fiberglass insulation outlets hesitate to reveal their wholesale price or let you buy online? Essentially, these sellers worry that if they disclose their wholesale price, the average buyer will request or demand a price reduction, threatening their profit margins.

Also, selling online reduces margins. It’s that simple! These sellers know the more ignorant the buyer is of the actual cost, the higher the probability of earning more from them. Moreover, offering retail prices ensures the seller a cushion for negotiations.

You’d like to know the wholesale fiberglass insulation price because…

  • You want to be empowered!
  • You don’t want to haggle!
  • You want the assurance you are not overpaying!

Did You Know?

Most of the vapor barrier, fiberglass insulation, and metal buildings sold across the U.S. originate from just a few major manufacturers. These large corporations distribute their insulation products—including moisture barrier insulation—through layers of retail outlets, including subsidiaries, regional dealers, contractors, and general resellers.

Here’s the truth:
Even if you gather 20 quotes, chances are you’re reviewing the same exact material—just sold by different outlets, each tacking on their own markup. These traditional sellers have no real incentive to offer the lowest prices on vapor barrier insulation. Their profit is often tied to how high they can price the material.

Now, we’re not saying there’s anything wrong with these companies. But their lack of price transparency makes customers feel like they need to keep shopping around. The misconception that “you get what you pay for,” touted by retail sellers, leads the majority to believe that higher prices equate to better quality. This misconception drives people to stick to the outdated practice of seeking quotes from traditional retail sources, thinking the best deals are only there.

Many need to realize that traditional outlets inherently charge retail, as there’s no incentive for them to do otherwise. The more you pay, the more they make! The public, conditioned to accept retail practices, continues to pay retail fiberglass insulation prices without considering the obvious. They will always pay retail unless they buy from a source that is not financially motivated by increased profits.

Though the majority of our sales go through only a few suppliers, we’re not limited to promoting a single brand or supplier. That independence allows us to leverage our network to access the lowest wholesale rates and pass those savings directly to you.

The motivation to reveal the actual wholesale costs

About 15 years ago, a friend suggested I use a car broker for my vehicle purchase since I was challenged to buy a particular car in my preferred price range. I went ahead with the broker despite my initial skepticism due to a $500 upfront fee. It must admit, it was pleasantly surprised. The broker presented the car with all the features I requested within a day. The best part is that it saved me thousands of dollars! This inspired me to present an even better program: Reveal an actual wholesale cost that confirms savings before expecting ANY fee payment! Since implementing the unique approach, we have received numerous compliments and have been encouraged to continue the transparency. Please feel free to give me your feedback. We are always looking for ways to improve our service to the public.
