30×40 Metal Building: Popular Options + Cost Guide

gray metal building with two garage doors

A 30×40 metal building is the perfect size for large garages, workshops, storage sheds, and more. Since steel is a durable and weather-resistant material, these structures require very little upkeep. Our 30×40 metal building prices are the lowest you’ll find and include installation.

Customizable Features

Design your 30×40 metal building to fit your needs. The following are available features:

  • Roof style
  • Color of roof, trim, siding, and doors
  • Garage doors
  • Walk-in doors
  • Windows
  • Insulation
  • Lean-to additions

How Much Is a 30×40 Metal Building?

The average 30×40 metal building cost starts around $11,000, though prices will vary depending on the roof style and height.

For example, a 30×40 steel building with a vertical roof, 9-foot legs, and a 9×8 garage door starts at $11,005, while a structure with 12-foot legs and two 10×10 garage doors would start at $13,325. Additional garage doors will increase the price, as well as taller sides.

We also offer a wide range of add-on features and accessories, such as windows and walk-in doors, for our metal buildings that will add to the total price.

Concrete Slab Cost

The average cost of concrete slab is $8 per square feet. For a 30×40 concrete slab, which is 1,200 square feet, the approximate cost  will be $9,600. Local prices of concrete vary depending on the cost of labor in your area. You can use our concrete pad size calculator to determine the best size for your needs.

*Please note that we do not provide concrete work with our metal building kits. You will need to hire a local contractor for your foundation.

Color Options

While traditional metal buildings were generally one gray color, modern versions have more options. Ours come in a  variety of colors, where you can change the look of the roof, trim, siding, and garage door.

Uses for Metal Buildings

The greatest thing about a metal building is its versatile use. New metal buildings can function as a garage and easily add value to your home. They also make great workshops, storage buildings, and barns. Our metal 30×40 garage kits are custom-made to fit your specifications and available in 16 different colors.

Installation

After ordering a metal building kit from us, we’ll deliver it to your home and install it for free. Installation can take anywhere from a half-day to a full day, depending on the size of the building. 

It’s important to prepare and level the ground beforehand to ensure proper installation. There should also be at least 3 feet of space around the desired area for workers to have room to install the building.

Frequently Asked Questions

Is a metal building better than wood? 

When comparing metal to wood, you’ll find that metal is a much more durable material. Unlike wood, metal does not crack or chip under extreme temperatures. It is also fire-resistant and less likely to dent or become otherwise damaged. Best of all, metal is low-maintenance, and its siding can last up to 40 years before needing a repaint. 

Is it cheaper to buy a metal garage or build one?

It depends. The average cost to build a garage is $28,000, though you can buy a metal garage kit for half the price. The total costs of both, however, will vary by size, style, customizations, and other factors. 

Are metal buildings cheaper than stick-built?

Yes. More often than not, metal buildings are half the cost of those made of wood. Since metal is more affordable than lumber, the material is a great investment for a large-scale, permanent building.
