Hollow vs Solid decking

Some solid decking board competitors 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 the negative publicity: it’s easier and faster to produce a solid board. Many manufacturers don’t have the skills or knowledge to extrude a hollow decking board as it requires a high degree of expertise and knowledge, including access to the latest composite machine technologies widely used in the logistics, packaging and aerospace industries.

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. This can loosen fixtures and fittings causing movement which can lead to warping. A hollow decking board core can easily expand and contract due to their honeycomb circular core, therefore are less impervious to rapid changes in weather and temperature typically associated with the UK weather.

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 nest. 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 uses 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 have weak points at the centre and each corner. For example: A metal tube can take more weight than a square one.

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