Options of Structure or Framework materials for your Best Deck Composite Products

Underestimating the importance of the structure or framework is a costly mistake that Best Deck sees and deals with on a regular basis. When it comes to the installation of composite wood products, there is and can be nothing more important than ensuring a solid rigid construction using the very best materials available for this aspect. This will ensure the longevity of the composite products you have chosen, helping them to outlast their guarantees for that specific application.

The Cost of making the Wrong Decision when it Comes to Choosing the Correct Structure

The financial cost of not being confident that you have the very best in structure or framework options is something that one will only see after a period of time. At Best Deck, our experience has taught us always to over-engineer the framework rather than just applying the standard installation requirements. Over-engineering the framework does not mean lots of additional costs (in many cases, there are no additional costs). The small things need to be done correctly and attention paid to ensuring the structure or framework is rigid in all aspects. These will ultimately make a big difference to the long-term future of your product.

Building a Solid Foundation

The framework or structure is the foundation to whatever planking system one would install onto it. As the foundation to build on, it works on the same principle as building a house – when you build on a bad foundation, the building will ultimately fail. Install your composite planking onto a bad or incorrectly installed framework, and the same thing will happen – the product will ultimately fail.

Experience is Knowledge

At Best Deck, we have paid our school fees and we know what the best structure or framework options are for any given applications. Added to this is our expertise in the commercial application of all our Best Deck products. We are specialists in what we do.

The Best Deck Turnkey Option

When Best Deck quotes on turnkey supply-and-install options, you are absolutely assured that we have quoted on the very best of everything. If Best Deck is installing your project, we are guaranteeing all aspects of the project. We’re guaranteeing the structure or framework, and that it has been done correctly so that the lifespan of the product outlasts what it is designed and intended for.

In addition to the structure or framework, there are a few more import things to note when Best Deck are your contractor of choice:

The installation of the structure or framework is also over-engineered so that it outlasts the time frame for which it is designed and intended.

There is a right way and a wrong way to install the planking. This is only done the right way at Best Deck. One will never see any back-to-back planking in our installation. We use what Best Deck refers to as a breaker board, which aesthetically enhances the look of the layout, and can also be done in a contrasting colour (which looks beautiful). Breaker boards mean NO BACK-TO-BACK joins in a Best Deck installation.

Experience Sets us Apart From the Rest – Almost 100 years Between the Three Directors

At Best Deck, we strive for the very best end result for every project. A lot of companies fall short here. This is where, when it comes to comparing prices, it is critical that one is comparing a specialist in the industry’s price to another specialist in the industry’s price. Is the structure or framework material of the same specifications (size, thickness, and even type)?

Daily, we deal with enquiries where the potential client is comparing a timber deck structure to a galvanised steel structure. Although the galvanised steel price often is not much different to natural timber, this isn’t a wise approach to an apples-for-apples comparison.

Perfection is the End Result we will Always Strive to Achieve

The finishing off has to be given the attention that it requires. This is what everyone sees. At Best Deck, we know this. We appreciate that we could build a beautiful 500 square metre deck and that just one or two loose fascias could ruin the whole look. Until that is sorted out, our client won’t even see the beautiful deck. All they see are the two loose fascias. We get that.

If Best Deck supplies and installs your project, this would include our structure or framework and our full-time after-sales service team. We have full confidence that, if we’re called out on a maintenance issue under the Best Deck guarantee, the problem is always small and easily sorted out.

As in every industry, things can go wrong every now and then. At Best Deck, we are efficient in dealing with customer service-related issues. They are our priority.

At Best Deck, We Understand That You are the Client

The reason that all of this is relevant to our material structure page is that the end result requires all of the above. To achieve this, you have to start with the correct foundation. This is the structure or framework.

Best Deck supplies all our products to anyone who would like to purchase them. We have contractors and clients nationally and internationally.

These clients purchase the structure materials that they require for their own specific projects, in addition to supporting Best Deck by buying the composite profiles they require.

At Best Deck, we will go out of our way to ensure that our clients always get the Best Deck service, which includes (amongst a lot of other good stuff) being given the correct information to ensure you are purchasing the correct materials for what you need. We ask that, when enquiring or ordering a product, you provide the correct information relating to your request. This is important so that both parties are on the same page.


There is nothing more important than the supporting structure or framework for a specific product and profile. One must ensure the materials used for this application will handle the environment for which they are designed and subjected. It is not uncommon for there to be a combination of materials for different applications where structural material is required and engineers are possibly involved.

Galvanised steel

Lightweight Galvanised Steel – C Channel – 1.2mm thick – 1.2mm wall

Galvanised Steel Structures and Framework – For Inland Projects

On inland projects, Best Deck does not use timber in a normal application as the supporting material (there are exceptions). In regions where the air is dry, with very hot and then very cold conditions, rain and moisture (like the Highveld, Gauteng), timber does not generally work well. Trying to maintain timber structures or frameworks in these conditions becomes overwhelming and impractical. In some cases, you have limited access to what you can see and maintain. In these cases, a galvanised steel frame makes much more sense.

Timber is a natural product. So, it has a limited life span. Without constant nourishment from wood preservatives, the lifespan of a timber product decreases very quickly and dramatically. It only makes sense to use a durable material. The best material we currently have available in our industry is galvanised steel. So, all of Best Deck’s inland projects are done only using galvanised steel or our solid plastic or composite wood profiles.

This 1.2mm wall thick x  65mm x 35mm x 15mm(as it a C Channel) x 6000m Long Light  galvanised steel is suitable for any and most residential projects and can also be used in commercial projects, Best Deck use it all the time

Galvanised Light weight C channel is a standard stock item.

Solid Composite Wood Joists

This is an amazing profile that lasts for a very long time. It is also 100% maintenance-free, and is rot- and termite-resistant. While there are various other applications for this profile, this is possibly the best profile available for the structure or framework for your composite wood installation and application. For this reason, it costs more than all the other structure options.

This solid composite wood profile can be machined like timber. It can be reduced in size or thinned out to accommodate installations where the space is limited. For example, if a door needs to open over the deck, the plank thickness can be reduced so that it fits comfortably between the existing floor and the bottom of the door.

This profile can have a small void between the ground and this joist, unlike the recycled plastic joist.  It is very strong when it is supported at 350mm spacing and gives an even better result than galvanised steel.

If you are going to apply this installation application, please ensure you use an expert to avoid very costly mistakes.

solid plastic joist

Solid Recycled Plastic Joist

Being 100% maintenance-free and resistant to rot and termites, this is the perfect profile to use, provided it is on an installation application that is on something level and solid (like a level concrete or tiled surface).

These recycled plastic battens /joists/ spacer profiles work well when there is no void (gap) between the joist and the solid surface. They like to sit flush onto a solid foundation and are ideal for conditions where one does not require a raised structure. All composite profiles require support or a spacer and cannot be fitted directly to a surface.

This installation application requires an expert.

CCA Pressure treated timber

Timber Structures and Framework – For Coastal Projects

For structures and frameworks that are erected or installed at the coast, close to the sea, or where there is a high salt content in the air, timber is the way to go.  But, the correct timber and the correct timber type are essential.

In our industry, CCA treated pine is usually the timber of choice. BUT, CCA pine and pressure-treated CCA pine are very different. Pressure-treated timber undergoes different treatments and is treated to different H Factors. H1 is the lowest and H5 is the highest. H4 or H5 pressure-treatment timber is optimal. In addition to this, a Waksol / carbolineum or bitumen treatment must and should be done to the timber too.

On a timber structure or framework, it is always better to go a bit chunkier on the material. Going thicker on the timber sections often does not add a lot to the bottom line, but will make a big difference to the longevity of the timber structure. A heavier, chunkier piece of timber means a longer lifespan.
