Metal buildings vs Modular Buildings 2020 Guide

Metal buildings vs Modular Buildings


If you’re looking to build either a modular or a metal building, you might be stuck with an essential question; what is the difference?

How can I benefit from either, and which one is best for me?

This is where Green Building Elements comes in.

In this guide, you’ll find out everything you need to know about metal and modular buildings, including what they are and the benefits to both.


Let’s go!

What’s in this guide?

Metal buildings

Metal buildings are traditionally made from prefab or ‘prefabricated’ kits which means that they are manufactured in a factory, and so they are prepared to specific needs and requirements.

This can mean that you won’t need to spend nearly as much time on building your home or commercial building, as you would if you needed to create everything on site.

Often, metal buildings will be created from flexible but strong metals like aluminium or steel, which range in price depending on the thickness and the sub-types of metal.

They are also typically much more cost-effective thanks to the versatility of metal, especially as in some cases you won’t even need professional builders to help you to put everything together.

There are many different providers of metal buildings, with each one providing specific benefits to their customers.

✔ Unique colour schemes to choose from

✔ Easily customised

✔ Might not need professional builders

✔ Expand the size of your building

✔ Door and window options

✔ Includes plans and drawings

Modular buildings

Similar to metal buildings, modular buildings are often prefab and arrive in separate parts, but unlike metal buildings, they need to be put together by builders.

Each one of these modular buildings is typically installed with a self-supporting structure, which can often be joined with another modular building.

This can mean that while you are limited to how big a single module can be, you can always expand using multiple modules like blocks.

Modular buildings are typically used in the circumstances that you have structures that need to be replicated; such as dormitories, classes in schools and storage buildings.

✔ Quick construction times

✔ Fewer costs

✔ Easy to expand

✔ Good to replicate buildings

✔ Versatile in design

✔ Mobile

The main differences

The main difference between metal buildings and modular buildings is that while each module is restricted regarding individual size, a metal building is on the whole limitless regarding size.

Certain skyrises are made with traditional metal building frames because of their versatility and strength.

Modular buildings can often stack on top of each other easily, or slot in side by side, whereas metal buildings are traditionally unique structures.

✔ Modular buildings are best for classrooms and student accommodation

✔ Metal buildings are often more suitable for commercial properties such as shops or motels for instance

How can I benefit?

There are many benefits to choosing either a modular building or a prefab metal building, so here are some of the main advantages of having a structure made out of steel.

Prefab means that a building’s parts have already been made in a factory, so when they are delivered, they can be quickly put together.

This can save you a lot of time, allow you to do specific building tasks yourself and you can rest assured that these parts have been built to specifics to fit together.

Here are some of the benefits:

✔ Faster to build

✔ More affordable

✔ Simple construction

✔ Easy to expand

✔ Customisable

✔ Adds value

Or, you can opt for a modular building system, which has its advantages which include the following:

✔ Can be easily duplicated

✔ Quick construction

✔ A temporary solution

✔ Easily customised

What are the disadvantages?

While there are many significant advantages to choosing either a steel building or perhaps a modular option, there are also some disadvantages that should be considered.

Let’s take a look at some aspects of steel buildings which should be analysed before making any solid decisions:

✗ You need to make sure steel buildings are allowed in your area

✗ Steel buildings are harder to transport than modular structures

✗ These types of buildings are more permanent than modular buildings

✗ There are funding issues to consider as steel buildings usually require loans

There are also some disadvantages to using a modular structure as well.

✗ You need to adhere to your land regulations

✗ There might be a struggle to obtain financing

✗ Modular buildings have a lower resale value

✗ There might be size restrictions


In conclusion, there are many differences and benefits to having either a metal building or one that is modular in design.
