Metal Structures Are Not Energy Efficient

One of the most common myths regarding metal buildings is that they are not energy efficient. The reason why this myth is so persistent is that there is some truth to it.

The location is one factor that affects the price of pre engineered metal buildings. Different locations have different prices for steel structures, so if you want to save money, pick a place where the cost of construction is low.

Material Used

The type of material used is another factor that affects the price. Typically, pre-engineered steel will cost more than a standard 40 X 100 metal building. If you would like to cut down on costs, consider using a standard steel structure and customizing it yourself.

Size and Additional Features

Building Style

Another factor that affects the cost of construction is your building style. For example, if you want a flat roof, then expect to pay more than if you would like a gabled roof.

Steel Buildings vs Concrete Buildings

Concrete buildings and steel structures cost about the same. But there are other factors to consider such as:

  • Concrete is susceptible to heavy weather conditions like rain, snow, and ice (but this can be fixed with insulation). Steel on the other hand does not rust or rot. It lasts longer than concrete.
  • The size of steel buildings is not as limited compared to concrete construction. Steel offers a wider range of size and design options for customers.
  • Because concrete can be easily molded, it is often used for complicated designs such as archways and columns; steel on the other hand offers fewer design possibilities and has more limitations.
  • Concrete can be tedious and time-consuming to construct. Steel structures are relatively quick because they’re prefabricated (but this depends on the manufacturer).
  • Concrete buildings need insulation to make them energy efficient; steel buildings do not require insulation, but might if the structure is only used for business purposes.

Initial Cost vs 40 X 100 Metal Building Prices

Vertical Roof Flashing

The vertical roof flashing is the most common way to go in terms of roofing. The vertical roof flashing offers an uninterrupted look compared to other types of metal roofing where seams can be seen.

It also is the easiest to install with the least amount of hassle.

V-Clip Flashing

The v clip flashing is a metal roofing system that uses a c-shaped clip or a u-shaped clip with a v cut in it to attach panels together. The advantage of using metal roofing systems is their lightweight and ease of installation.

Seam Style

One advantage to choosing metal over asphalt shingles is the straight seams. Because it’s a metal roof, you can install one panel after another with no visible seams from underneath because it all looks like one piece of roofing. This makes for a much more pleasing appearance than having the seams visible from the ground.

Workmanship Quality

Just because a certain type of metal roofing is more expensive than another does not mean it’s of better quality. It’s important to read reviews about a certain company and ask for references from past customers who have tried that style or brand before you make your purchase.


As can be seen, there are several factors that affect steel building prices. However, if you choose standard structures and customize them yourself to fit your specific needs, then you can get a very high-quality steel building at an affordable price.
