Timber frame shed vs steel shed: How do they compare?

When building a shed, the type of frame is something you shouldn’t overlook. It’s the structure that holds everything together and the longevity of the shed depends on the material you’d use. In most cases, the choice boils down to steel frame vs timber frame. 

This guide will break down the pros and cons of each frame type. We’ll make it easier for you to decide which is the best fit for your shed.

A timber frame shed is a structure primarily built from wood, often using timber framing and rough-sawn timber poles. These sheds offer versatility, which allows for customisations like adding shelves, windows, or lofts.

When comparing metal and wood shed materials, though, wood or timber sheds are more valued for their natural insulation, soundproofing, and resistance to rust. They’re commonly used for agricultural, workshop, and lifestyle purposes. Timber sheds can also withstand weather conditions while providing a sturdy, durable space for various needs.

What is a steel shed?

A steel shed is a structure made from rolled or structural steel frames, often galvanised for added corrosion resistance. Steel sheds are known for their durability, weather resistance, and pest-proof qualities. They’re popular for industrial or residential storage.

If you want to build a shed that lasts, steel is an excellent choice due to its durability. Its strength even offers the advantage of spanning larger distances without additional support. Steel is also non-combustible, which is a major advantage for those deciding to get barns over sheds in fire-prone areas. Another advantage is their lightweight property, which makes them easier to construct and maintain.

Steel frame vs timber frame for sheds: Which one should you choose?

When deciding on the frame to use for your shed, it’s important to look at several key factors to see which one suits your needs best. Both are popular types of sheds, but they offer distinct benefits depending on what you’re using them for. In this comparison, we’ll examine durability and how each material performs in different weather conditions.

In terms of durability

Steel frames offer excellent durability, as steel buildings are naturally resistant to rust and termites. Galvanised steel, in particular, offers protection from rust. However, it’s important to maintain it to prevent corrosion, especially when you’re building your shed in humid or coastal areas. 

If you’re seeking even stronger shed frames that will last longer, steel sheds enhanced for better durability are a great option. For instance, Easyshed uses high-tensile steel with a 0.30mm Base Metal Thickness (BMT) and 0.35mm Total Coated Thickness (TCT), while their Big Sheds range features even sturdier 0.42mm BMT and 0.47mm TCT for added strength and longevity.

Timber frames are naturally durable when properly treated, as timber helps resist rot, moisture, and pests. However, untreated wood can decay in harsh weather conditions, so protection is necessary. 

Timber frames also hold up well against physical impacts. This makes them suitable for areas where building a sturdy shed foundation is important, especially when heavy equipment is involved.

In terms of insulation

Timber naturally provides better insulation to sheds, which makes it effective at maintaining a stable temperature inside. This is ideal for workshops or other spaces where warmth is needed. Also, timber absorbs sound, so it’s quieter inside, especially during bad weather or when working with noisy tools.

Steel is a poor insulator, so steel-framed sheds often get very hot in the summer and cold in the winter. You’ll need additional insulation to maintain a comfortable temperature. Steel also amplifies noise, making it much louder during rain or hailstorms compared to a timber-framed shed.

In terms of resistance to rust and termites

Timber frames can be vulnerable to termites, which can cause severe damage if untreated. You’ll need to apply termite-resistant treatments and perform regular inspections to maintain the structure. But in terms of rust resistance, timber frames are mostly better than steel, making them ideal for areas with high moisture.

If you prefer steel frames, you won’t need to worry about pest damage. However, steel is prone to rust, particularly in coastal or humid environments. 

One way to prevent this is to opt for galvanised steel, but weak spots like screws or scratches can still rust eventually, so they’ll still require extra care.

Another solution is to look for trusted shed manufacturers like Easyshed, which uses high-tensile steel that meets industry standards. This high-tensile rating ensures that their steel sheds won’t rust under normal conditions.

In terms of the aesthetics

Timber frames offer a natural, rustic charm that complements modern garden ideas centred around warmth and character. You can either paint or stain timber, so homeowners can easily match their timber garden sheds to their home or outdoor furniture assembly. These sheds also lend a cosy, inviting feel to a space.

Steel frames bring a sleek, industrial vibe. While practical, steel garden sheds are more limited in customisation and are often chosen for their durability rather than looks. Though you can paint a steel shed, the overall design remains minimalistic, which makes it harder to incorporate personal touches like windows or decorative accents.

In terms of maintenance

Timber frames need regular maintenance, which includes inspections for pests like termites and applying weatherproof coatings to protect against rot and warping. Repainting or staining is often necessary to maintain the natural wood aesthetic. Untreated timber may suffer from shrinkage or warping if exposed to moisture over time.

Steel frames require less maintenance. They don’t require painting or staining as frequently and are immune to termites and other pests, which cuts down the need for pest control. However, rust prevention is important, especially at vulnerable points like screws and scratches in the protective coating. 

Cleaning a steel shed is also pretty straightforward. According to shed experts from Easyshed, a standard wash down using soap and water once a year would be enough to keep a metal shed looking pristine for years on end. 

In terms of cost

Timber frames typically have lower initial material costs, especially when using common woods like pine. They range from $1,250 to $1,650 per square metre. They’re easier to construct, so if you’re planning to install a garden shed or any other type, you’d spend less on specialised labour. However, timber sheds require ongoing maintenance, such as termite treatments and weatherproofing, which can add to the overall expense over time.

Steel frames, on the other hand, have higher material and construction costs due to the price of steel and the need for expertise during installation. The usual cost of a steel shed in Australia ranges from $256 to $2,849. However, they are much more cost-effective in the long run due to minimal maintenance needs.
