30×120 Steel Structure Dimensions & Uses
Pre-engineered metal buildings allow businesses and private owners to construct large spaces for affordable prices – with savings to be found in materials, labor, and time. Offering over 3,600 square feet to work with, a 30’ x 120’ metal building would be the ideal structure for:
- Small-Scale Manufacturing
- Merchandise Warehousing
- Agricultural Equipment Storage
- Shipping and Logistics Center
- Home and Office/Workshop
The sky is the limit when it comes to pre-engineered metal buildings, and there are a variety of design and architectural solutions available at an affordable price. In fact, a 30’ x 120’ x 16’ pre-engineered metal building would roughly cost between $32,530.00 – $41,530.00* plus shipping as of February 2026 – only $9.04/sq. ft. to $11.54/sq. ft. – if designed for non-snow areas with light, standard wind speeds. Special conditions and code requirements may affect your price.

What Does It Cost To Insulate a 30 x 120 Metal Building?

Fiberglass blanket insulation – with its bright, white finish – is another accessory that can brighten the interior of your building while saving you money. Pre-engineered metal buildings will last for decades with minimal maintenance, and insulating your building will save you thousands over the years.
4” R-13 insulation is a favorite as it can be sandwiched between the framing and sheeting of your building during construction. The cost of insulating the roof and walls of a 30’ x 120’ x 16’ metal building with 4” R-13 is only $4,980.00 to $5,320.00 before shipping! This price even includes having the rolls custom cut for your building to aid with installation.
