Location, Location, Location

The geographical location of your building project will affect the overall design and price of your 30 x 40 metal building. Depending on the weather in your project’s area our engineers will need to design your building with wind speeds and snow loads in mind. Maverick Steel Buildings‘ expert engineers will design your metal building to meet the code requirements of your area.

Don’t Forget The Slab

You must ensure that other costs, such as labor and materials for your building’s concrete slab installation, are properly accounted for. Concrete slabs generally cost between $4 and $8 per square foot including labor. A typical 30×40 concrete slab at 6 inches deep could cost around $7,200 depending on a number of factors including your building’s location.

Electricity, Plumbing, & All The Trimmings

Keep in mind that when you purchase a 30×40 metal building kit from Maverick Steel Buildings this does not include interior walls, electrical wiring, plumbing, ventilation, or HVAC systems. These components are purchased separately and you must account for the material and labor costs you will accrue while finishing your building project.


In addition to keeping the ambient temperature at a more comfortable level, insulation works to prevent condensation from forming on the steel panel walls of your building kit. A buildup on condensation can cause corrosion of the metal which could affect the stability as well as the look of your building. The cost of properly insulating a 30×40 metal building should be around $2,400-$2,800, depending on the height of the walls (12ft to 16 ft).
