About the decking lengths

Some different features of different decking lengths are added here.

Weight: Longer boards mean heavier weight.

Installation: Longer boards will be harder to fix and more troublesome to install.

Temperature changes: WPC decking will expand and contract slightly when faced with temperature changes, and in this regard, shorter boards are fewer significantly than longer boards.

The 3.6m composite decking boards have better aesthetics than other lengths. Therefore, it has a better installation effect.

About the deck width

The choice of deck width is more flexible. It depends on your aesthetic preference and the width options the manufacturer can offer. If you are not sure at the moment, you can contact the manufacturer for a sample to easily see the actual visual effect.

About the deck thickness

The deck should provide a solid surface that holds the weight of the people and furniture on the surface. If the deck is too thin, there will be a bouncy feeling when you walk on it. When choosing the thickness of the deck, the spacing between the joists and the weight distribution should be taken into account. Ensure that the areas that are not touching the joists are also solid enough.
