A deck can be the perfect place to entertain guests and chill outside!

But the most important thing about installing a new timber deck involves deciding on the kind of deck support. In this regard, two main types of decking support are timber and steel deck framing. Both have advantages and disadvantages, so choosing the right one for your project is essential.

And in the following sections, we will help you do just that.

Why Choose Timber?

Timber is entirely natural and can be used to make the base for decking. It can contract, expand and move depending on the different weather conditions.

Also, when using timber joists with a timber base, the entire deck structure reacts to changing weather similarly. This reduces the stress that is put on the boards, ensuring longevity.

Timber screens can work perfectly to provide shade while you sit back and relax outdoors. It will keep intruding neighbours away and prevent them from being able to spy on you.

And that is not all; this material comes in different subtle shades to match the deck with your garden decor or the pool fences without repainting it. The natural colour of timber will always stand out.

What Are The Recommended Timber Substrates?

Types Timber Substructures

1. F7

When you see the letter “F,” you should know that it refers to the strength of the timber. A higher number will mean the timber is stronger, and you should not settle for anything less than F7.

F7 and treated pine work well for outdoor deck, large gazebos, and pergolas.

2. H4

H” refers to hazards and indicates the timber’s resistance to environmental hazards, including insects, decay, and other organisms. H4 timber will be very resistant to decay and can be used for outdoor projects. Besides, it can be used for in-ground installations without being affected by moisture and is a great option to pick.

3. H3

If you need timber for above-ground projects, then the H3 rating should work well. H3-treated pine is resistant to decay and insects and can remain in place for a long time.

Why Choose Steel?

You have guessed it right- the primary advantages of steel include high strength and durability. Not only that, but the material is also adaptable, meaning it can accommodate curves and turns without causing any trouble. And you don’t need a lot of time to install steel decking.

Steel is known for its compatibility with other materials. Hence, you can always use it in parts to strengthen the decking boards, especially for large steel decks needing additional support.

To do this, you can use steel bearers with timber joists and then attach them to the base of the deck. This will help you use the strength of steel without compromising on the decking.

Comparing Steel With Timber

Timber is a natural material that is less likely to cause issues with expansion and contraction. However, it is more vulnerable to rotting and pests, so it may not be suitable for all applications, especially if the area sees a lot of rainfall.

Another point to consider is that steel is much stronger than timber, so if you have a large or elevated deck, it may be the better option. However, steel can corrode over time, so it’s important to protect it from the elements properly.

Timber With Steel — Is It A Good Idea?

Some people do opt for steel joists along with timber boards. But you must know that steel is less sensitive to the environment than timber. So, it contracts and expands at a different rate compared to timber. This can put more pressure on the fasteners and the decking and may even cause the timber boards on top to split or warp over time.

Outdoor Raised Timber Deck

In short, using steel joists with timber boards is not a good idea, especially if the climate changes often. The steel will not change its shape while the timber will expand, leading to disastrous results and putting a hefty strain on your pocket for the repairs.

Another thing to consider is aesthetics. Timber will give you a classic look and go well with wooden houses. On the other hand, steel decking supports will be modern and streamlined.

What Decking Supports Are Right For You?

With that, it is time for you to enhance the aesthetics of your house with a beautiful deck using the right material according to your needs.

We will always suggest getting professional help for the purpose. The installation process of the frame, bearers, and joists may become extremely taxing without expertise. Besides, you may waste the material and weaken the deck’s foundation. And fixing it can burn a hole in your pocket.
