Pros of steel-framed tiny homes

There are many exciting benefits of using steel frames for your tiny house project.

While steel is lightweight and way better than wood, it has other brilliant advantages as a framing material.

Here, check them out

Highly durable

In terms of durability, steel is way better than wood and other materials used for tiny house projects.

Unlike wood, steel does not expand or warp.

Because steel is flexible and can bend without cracking, it can withstand hurricanes and earthquakes.

Steel is estimated to last almost 150 years, regardless of how it is exposed.

Fire resistant

Thanks to being fire-resistant, steel will prevent fire spreads.

Despite its inflammability, steel loses strength when exposed to temperatures above 500 degrees Fahrenheit.

Considering that residential house fires can reach a whooping 1000+ degrees Fahrenheit, it means steel frames will only retain 50% of their actual strength in case of fire emergencies.

Steel is moisture resistant

Unlike wood which succumbs to mold, steel has proved to be highly resistant to mold.

To this end, it can withstand water damage without taking a beating.

Also, galvanised steel and zinc coating treatment tend to increase steel frame performance and make it resistant to rust.

Steel saves time

When building steel frames for tiny homes, you don’t need to deploy heavy equipment.

And yes, steel frames can be premade and transported easily to your desired location.

Also, assembling steel frames is not as challenging as you imagine.

Many times, steel frames for tiny homes come with pre-made holes, making the entire process easy for you.


One thing we love about steel frames for tiny homes is that they are easy to customise.

This makes it easy to bring your ideas to life.

And thanks to being easily customisable, you can seamlessly add cladding options such as vinyl, cement and more to make your home look stunning.

Environmentally friendly

Steel frames are environmentally friendly.

And the reason is that they are not made from harmful chemicals.

And yes, steel doesn’t require any chemical processing before it can be reused.

Another thing we love about steel is that it is 100% recyclable, which is a big deal.

Cons of steel frames

Though steel framing has many exciting benefits, it isn’t without a few drawbacks.

Here is what we don’t like about steel framing for tiny homes.

Insulation is challenging

One of the biggest letdowns with steel frames is their poor insulation.

Also, it suffers from low energy efficiency.

And the reason is that steel tends to conduct more heat, especially when compared to wood.

Because of thermal bridging, steel loses 60% of its insulating properties.

To fix these problems, most tiny house owners spend extra, wrapping insulation boards around steel beams.

Also, some people prefer to use hybrid steel/wood frames.

Whatever the solution, you’ll still have to spend more.

Design drawback

Even though steel-framed tiny homes are durable, they have quite some limitations, especially when it comes to design.

Unlike wooden roofs that can be tweaked, metal-framed roofs cannot be easily tweaked.

That said, you can add a wooden frame for the roof to solve the design limitations of steel-framed homes.


Despite being immune to damage, rust is the biggest issue confronting steel frames.

Once exposed to leaks for prolonged periods, your frame may succumb to rust damage, ultimately affecting the stability of your home.

It may even lead to a costly repair.

Thankfully, you can deploy coatings and paints to prevent rust.
