Armstrong Steel Buildings and Metal Building Systems

Armstrong metal building systems come standard with a 50-year structural warranty. Each piece of steel is representative of our experience, know-how and cutting-edge technology. Armstrong Steel building projects are "built" on-screen by in-house detailers before the plans are approved by you.

Pre-engineered steel buildings by Armstrong Steel are AISC-MB and IAS Certified, PLUS:

PRE GALVANIZED Purlins, Girts and Door Jambs protect against red rust during and after metal building construction. Galvanization extends the life of your project and the appearance. Our cleaner, brighter product also features lower maintenance costs.

Long-Life Finishes are used on all our metal buildings panels to achieve truer, brighter color that is longer-lasting and inherently has curb appeal. Matching gutters and downspouts are an added attraction. These Long-Life Finishes carry a 40 year paint warranty.

Stainless Steel Fasteners are used on all our metal buildings. Armstrong's roof and wall fasteners are surgical stainless steel fasteners that are supplied with an assembled neoprene washer and carry a lifetime warranty against rust.

I-Beam End Wall Framing provides strength and stiffness. Easy to erect as they stand alone because they require less bracing, our stronger hot-rolled sections are easier to handle than cold-rolled.

Purlin Bearing Rib (PBR) on Roof & Walls makes for a solid side lap seal in your steel building that reduces moisture infiltration and air leaks for a stronger, weather-tight fit and reduced maintenance costs.

Guaranteed On-Time Delivery with confirmation is a feature we stand behind. We ship steel buildings efficiently and our promptness means we can schedule your crews more efficiently, saving you time and money.


Armstrong Steel Buildings has taken what was once a manual, tedious exercise and streamlined production. In doing so, we save you money and aggravation. We deliver steel buildings that are faultless, something the manual process of yesteryear could not.
