20×40 Metal Building Prices: Counting Up the Total Cost

Whether you want to build a Metal Building garage, living area, cafeteria, storage hall or any other building occupying a space of 800 square feet, this kit of 20×40 can be convenient for you. 
On average, the kit will cost you anywhere from $8160 to $8800 (around $10.20 to $11.00 per square foot).

Note: Please be aware that the quoted price (above) is for the prefabricated kit. 

But when it comes to the complete erection of a metal building, there are specific costs that need to be taken into consideration, like:

  • Based on the quality of the wall and roof panels you go for, it is estimated that the construction cost for a 20×40 metal building will range between $5 and $10. 
  • In addition, make sure you add on the labour cost as it proportionally influences the construction cost.
  • Changes in the dimensions of 20×40 metal buildings can impact the calculation of the cost in various ways:
  • For example, increasing the width or height will augment the metal building cost as more compression members, tension members, combined force members, bending members, and connections will be required.
  • Metal building’s overall price is also affected by the gauge of the steel.
  • A gauge of steel specifies how thick a metal sheet is; if the sheet is thick, it will provide more strength (which will alter the cost) and vice versa.
  • Metal building insulation minimizes the structure’s condensation and heat transfer problems.
  • The quality of insulation, namely the U-Value, Vapour Retarders & R-Value, can significantly impact the metal structure price quotes.  
  • Furthermore, the purpose of building installation also decides the need and levels for insulation, altering the overall costs in the final quote.
  • Door sizes also alter the metal building prices.
  • The broader and more the opening, the more gear (equipment) will have to be installed for the power to be achieved appropriately, which could result in a higher quote (price).

Other walks and garage doors increase the prices of steel structures due to higher manufacturing costs and operating equipment demands.

  • Metal buildings must have solid and stable foundations that can endure even the most extreme and unpredictable weather conditions.
  • That being said, when it comes to concrete foundation costs, they range between $4 to $8 per sq. ft. Moreover, other foundation options for the metal building include slab foundation, piers and perimeter walls. Depending on the usage and type of building, Steel and Stud expert will help you decide the best foundation types.

The most common concrete foundation costs around $0.50 to $1.50 per square foot, and other options may vary between $4 to $8 per square foot. 

  • Steel and Stud metal building experts can help you make the right decisions regarding the planning and construction of a 20×40 metal building to ensure they are adequately ventilated and built to last. 
  • Moreover, there is also the option of customisation, where owners can specify a certain number of openings and windows (which will enhance the structure cost) according to the type of niche (business or personal) they are operating in.

Note- Prices on this website may change without any notice and should be read in conjunction with the terms & conditions published on this website. Also, we do not include the cost of concrete, insulation, and installation in our pricing.

Finance For 20×40 Metal Building

Metal Building may cost a considerable amount, and there are two ways to finance it-

Finance it by Yourself

 If you have planned for the cost of metal building and are ready to bear the entire cost yourself, this is the most cost-saving method. Financing metal building yourself will eliminate any interest or penalty costs, thereby helps saving money in the long run.

Opt for a Bank or Credit Union

Another option to get your loans is through a financial institution. Opt for loans from banks or credit unions you’re already a part of, as they have all the records from your transactional history and may help pitch a competitive price for the loan.

I ordered a pre-made 20x40 Metal building kit from Steel and Stud and got it delivered and installed in a matter of days. The pre-engineered metal building had high-quality galvanized steel frames, making them very sturdy. There are many pre-made building kits available, including barns, residential homerooms, commercial buildings, industrial warehouses, and garages. I recommend Steel and Stud for their professional and continuous support.
