Wholesale Cost | Profit/Fee |
$0 -$2,000 | $595 |
$2,001 – $10,000 | $795 |
$10,001 – $30,000 | $995 |
Two Payments (Most Popular – $200 Savings)
- At the time of order, divide the payment by paying the profit (brokerage fee) to Factory Steel Overstock and the Wholesale Cost to the supplier.
- Example: For a $9,500 wholesale cost, add $595* (brokerage fee) = $10,095 (total), of which $9,500 goes to the supplier and $595 is given to Factory Steel Overstock.
Wholesale Cost | Profit / Brokerage Fee |
$0 – $2,000 | $395 |
$2,001 – $10,000 | $595* |

Warning: A Common Practice of Steel Building Sellers
We don’t typically comment on the practices of other steel building suppliers. However, a recent experience shared by one of our insulation customers is essential enough that we feel compelled to pass it along. If there were only one article you read, it should be this one!
The customer had already purchased a steel building from a well-known seller and came to us afterward for insulation. Naturally, we asked why he hadn’t purchased insulation—and other necessary components—from the original supplier. His response was eye-opening.
He said the seller’s initial offer included only the bare-bones building—no framed openings, walk doors, windows, or essential accessories such as closures. He was told these items would be more affordable if he waited for a project coordinator to follow up after the purchase.
When the coordinator did reach out, he presented a list of add-ons—many of which are critical for any steel structure—at prices that were, frankly, outrageous. In fact, the cost of these “extras” exceeded the original price of the building.
The customer found himself in a difficult position. Having already paid a deposit and lacking the experience to source these critical components on his own, he felt pressured to move forward and pay the seller’s inflated prices.
Fortunately, after reviewing the proposal with us, he discovered that even after forfeiting his deposit, he could still purchase the necessary materials through us and come out ahead, with a net savings overall.
The takeaway?
Never purchase a steel building without first getting all, or at least most essential, components included in the initial price proposal. Do Not Wait for a Project Coordinator call! What appears to be a great deal upfront can quickly become an expensive and frustrating experience.
