40×80 Metal Building Design & Engineering
Pre-engineered metal buildings are versatile structures that can be designed with your business or recreational use in mind. Whether you need mezzanines for offices, large cranes for manufacturing, or smaller hoists for workshops and barns, your 40’ x 80’ metal building will offer 3,200 square feet of space that has been custom-made for any of the following:
Engineers will design your building as efficiently as possible, giving you a structure that is strong yet economically priced. Coming in at only $11.00/sq. ft. to $13.50/sq. ft. – your 40’ x 80’ pre-engineered metal building would only cost between $35,210.00 – $43,210.00* before shipping as of February 2026. Please keep in mind that this price assumes erection in a non-snow area with standard, light wind speeds. Your price may vary depending on local code requirements and special design needs.

Designed for Affordability
The next step in ensuring your pre-engineered metal building meets your needs is the selection of the appropriate accessories. A wide variety of steel access doors, overhead doors, and canopies are available to make sure the various entry points in your building will accommodate your activities; and there are also various ventilation options, windows, and aesthetic elements to choose from.
Your standard steel access door – also called an entry or man door – can be made with or without windows, automatic closers, panic/egress hardware. If there are ADA requirements, they can be accommodated with electrical kits, kick plates, and special thresholds. Finally, your steel access doors can also be made with special foam cores that offer insulation values or fire ratings to fit your needs!


What Does It Cost To Insulate a 40 x 80 Metal Building?
Of course, if you are considering insulation for your doors and windows, then you will likely be interested in doing the same with the rest of your building. Fiberglass blanket insulation is likely the most straightforward product for this purpose, as it is easily installed between your framing and panel during the construction of your pre-engineered metal building.
Due to ease of installation and value, 4” R-13 blanket insulation is the popular standard. For only $4,200.00 to $4,500.00 – before shipping – you could insulate the entire envelope of your 40’ x 80’ metal building with 4” R-13!
