9 Key Reasons to Buy a Factory Steel Overstock Steel Building

1. Building Manufacturer is IAS Certified

What separates fabricators is the ability to prove that their fabrication methods meet or exceed a rigorous independent inspection. Getting IAS (International Accreditation Service) accredited involves evaluating the fabricators’ management and quality control systems as well as verifying that the on-site inspections have met the requirements of industry standards and IAS accreditation criteria. Factory Steel Overstock I-beam steel buildings come from an IAS Certified fabrication plant.

When a system is IAS-approved you can rest assured, adequate fabrication steps have been met! This benefits the customer tremendously in the field. No one wants to be burdened with unnecessary additional labor costs because columns have been miscut or hole placements are inaccurate. Maintaining the accreditation requires periodic assessments as required by the building code. 

2. Buildings Backed with a 50 Year Structural Warranty

The key feature of a rigid-frame steel building is the I-beam mainframes. The material used is 50,000 p.s.i. yield strength (Some manufacturers use only 34,000 p.s.i. yield strength material). 

Factory Steel Overstock frames are single-bead, continuous submerged arc welded by automatic welding machines to help ensure quality. Factory-applied rust-inhibiting primer is used to help protect the mainframes and secondary material during the erection process. Specifications

Beware of companies selling 2” tube steel or back-to-back C purlins as their mainframes, for these are far inferior designs.

3. The Highest Quality Sheeting Materials

Factory Steel Overstock offers standard PBR panels for roofs and walls, which have a larger overlap than R panels.  Some firms utilize an R panel for their roof sheets (picture on right).  Most pole barns and tube buildings use a lighter 29-gauge sheeting thickness; however, Factory Steel Overstock utilizes a 24 or 26-gauge – 1 1/4″ profile, 80,000 p.s.i. tensile strength, PBR sheeting (Purlin bearing Rib).  For more information regarding building materials read Specifications.

4. Fully Flashed Framed Openings

One of the 1st things noticed when viewing a steel structure is the trim appearance, for it highlights the structure.  Factory Steel Overstock offers a fully flashed opening as a standard feature for all large openings. Industry standards only offer a simple trim at these locations – which shows the unfinished red iron. Why Buy from Us

5. 40-Year Paint Finish Warranty

Nothing enhances a building more or takes away from its appearance than the quality of the paint utilized. Industry standards are a 20 to 25-year color finish warranty. However, with Factory Steel Overstock there is peace of mind knowing the color warranty extends to 40 years. Remember, the industry-standard warranty is based on an allowable degree of fading before the 20 years have elapsed. Meaning, you will see some fading before the 20th year with industry standards!

6. Ordered Canopies & Purlin Extensions have SOFFITS

With Factory Steel Overstock, requested canopies and purlin extensions have soffits as a standard feature. 

Canopies- are on the sidewall. Purlin Extensions- are on the end wall. These are the most common items added to orders, simply because they enhance the appearance and performance of the building. The additional cost is minimal – with purlin extensions less costly than canopies. Our extensions are 1’ to 5’ and a soffit is a standard feature. 

Factory Steel Overstock’s standard practice is to soffit (sheet) purlin extensions and canopies up to 5′.

7. Transparent Pricing Program, and Guaranteed Savings

Let’s keep it simple: It is about getting the highest quality materials and services at the lowest possible prices. Factory Steel Overstock is the only outlet that informs the general public of the actual wholesale cost, reveals the profit amount, and guarantees savings. For example:

Jack Smith from Nashville, Tennessee Is looking to build a garage that is 40′ x 60′ x 16′ in size. For his building accessories, he wants:

  • Two 14’x 14′ insulated roll up doors -$3,140 ($1,570 per item)

  • One 3′ x 7′ insulated walk door-$361
  • R-Value 22 roof & wall insulation- $2,188
  • Two 9″ x 10′-0″ White Ridge Vents- $886 ($443 per item)

First, Jack found wholesale building costs for his specific state in our Pricing Glossary on the Building prices page (Found above). For Tennessee, Jack’s estimated delivered price for the base building is $26,408. To find the cost of the accessories he wants, Jack visited our Accessory Resource Guide, and our Insulation Prices page to locate the cost of his desired add-ons. Then, Jack added the cost of accessories to his base building price for an estimated subtotal of $33,583.
