Composite Decking Hollow Vs Solid

Some Solid Decking Board companies are publishing a lot of negative information regarding Hollow Decking Boards. Yes, they do use less material and are normally cheaper. However, Hollow Decking Boards are designed and engineered for their strength and durability.

A good reason for this negative publicity, it’s easier and faster to produce a solid board. Many manufacturers don’t have the skills, knowledge or latest machine technology to extrude a Hollow Decking Board. This requires a high degree of expertise and knowledge, including access to the latest composite machine technologies widely used in aerospace and car manufacturing plants.

How Strong is Hollow Decking?

Ultra-Decking’s Premier and Platinum range of WPC composite decking boards are manufactured with a circular honeycomb core, mimicking Mother Nature’s toughest structures. Indeed, many species of insects such as bees and ants use a honeycomb structure in their hives and nests. Tests have shown that a honeycomb structure can be up to 40 times stronger than a solid structure and weigh considerably less.

Unlike some solid decking boards, a hollow decking board will not warp, twist or bend. Ultra-Decking boards are made using a patented manufacturing process to produce a honeycomb circular core, achieving a stiffness and strength not found in solid composite boards. A circular honeycomb core offers an even weight distribution versus a rectangular or square core which has weak points at the centre and at each corner. For example, A metal tube can take more weight than a square one.

Ultra-Decking’s Signature and Premier range of composite decking boards have been independently inspected and tested by SGS, a leading global test and inspection organisation confirming the boards quality, strength and durability in the harshest of conditions.

Weather and Temperature Fluctuations

A composite decking board manufactured with a Hollow or Honeycomb Core is less impervious to the weather. Sudden changes in temperature and moisture fluctuations can cause solid decking boards to expand or contract over time.

These sudden temperature changes can loosen fixtures and fittings causing movement which can lead to warping.

The core of a hollow composite decking board can easily expand and contract, therefore are less impervious to rapid changes in weather and temperature which are typically associated with UK weather conditions.
