Grooved vs Ungrooved Composite Decking

in WPC Decking Tips 2021-10-13

When you consider buying composite decking, you may find that there are two different types: Grooved and Ungrooved. The major difference between them is whether there is a groove on the side of the board. This difference will not affect the overall appearance of the floor, but there will be significant differences in installation.

Ungrooved Composite Decking, like the traditional wood floor, all sides are flat and without grooves. These nonslotted boards cannot be installed with hidden fixing accessories. To fix the board onto the joist, screws or nails need to be drilled into the boards, so after installation, you will see screws or nails on the surface of the boards.

How should I choose?

Grooved Composite Decking changes the installation method to the traditional wooden floor, and the screws will not damage the board surface. You don’t have to worry about the screws become loose after a long time. Generally speaking, Grooved Decking requires higher manufacturing technics, and not all manufacturers can produce it. On the other hand, the use of concealed fasteners can regulate the spacing between the boards, and the suitable spacing is more conducive to drainage and ventilation, so as to improve the service life of the decking. We recommend you choose Grooved Composite Decking.
