Wood Plastic Composite (WPC) is a popular choice for timber decking fans. Not only that it looks natural with all the grains on the surface, it is also maintenance free relative to solid wood decking. But all these advantages would not count for anything without a strong and stable support foundation, which will be discussed in details in this blog.

So what is the reason behind such reliable strength that makes WPC decking safe and convenient? It is the solid foundation underneath that is normally invisible once the installation is complete. WPC planks are attached to each other by small clips that are screwed onto the perpendicular runners beneath.

For easier screwing process, aluminium square hollow section would be recommended for the runners.

Most WPC decks are installed with an aluminium support structure run perpendicular underneath, typically at an interval of 400 mm to 450 mm. These aluminium runners usually come in 2 inch size length with 1 or 2 mm thickness.

Aluminium does not rust either, contributing to its excellent durability for your decking support. Even in rainy season, you would not need to spend a single second worrying about the rusting of your decking support. In short, aluminium runners are among the favorite runners picked by timber lovers.
