There are grooved and ungrooved composite decking because there are two methods of installing composite decks.

Grooved composite decks are good for hidden fasteners, while ungrooved composite decks are good for surface fasteners.

Composite decking triumphed over wood decks because of the fact that they served as an alternative to wood decking.

To start with, composite decking can be made to look exactly like a wood deck. This is because some folk still prefer the wood finish of the wood decking. 

With the wood grain finish added to composite decks after it has been molded, composite decks can retain that popular woody appearance.

Another thing about composite decking is that they last longer than wood decking when they are installed.

This is because composite decking can withstand any kind of conditions.

With composite decking, you can mix colours when installing the boards to provide a gorgeous surface.

  Aside from colour mixing and a gorgeous finish, composite decking are stronger and more durable than timber decking.

This means that when you installed them in your residence, they will persist for as long as you want them to. 

Composite decking will not fade or break like the wood decks, and they will not absorb liquid.

Over the years, composite decking installation methods have been improved. One way of installing composite decking is by using screws or nails. 

The screw and nail method created a problem – the nail and screw surface appear on the deck finish distorting the look at times.

Producers of synthesized decking have made it practical to utilize unseen fasteners to clamp the deck to the frame.

This gives rise to different types of composite decking – grooved and ungrooved.

What Are Ungrooved Plastic-Wood Decking?

An ungrooved composite is a board that has smooth or square sides. The best way to identify an ungrooved composite deck is by looking at the sides.

You should look for composite decking and check the sides to see if they have hollows or channels running from one edge to the other. 

Why Are There Grooved and Ungrooved Composite Decking?

If there are no hollows at the side, then it is an ungrooved composite decking.

This type of composite deck was the first to be made and can be installed using screws or nails.

What this implies is that you have to utilize nails or drive screws down the ungrooved composite board to put it to the structure.

Using nails to install your composite decking will leave the head of the nail exposed to the surface.

Also, nails can be pushed up by the deck when you use them for a long time. When this happens, it is possible to trip and fall if your shoe should hook the nail. 

An alternative to installing composite decking with nails is using screws, and they are better than nails.

While screws can be coloured so that they blend with the finish of the composite decking, folks still prefer not to use them at all.

This is because they don’t want anything to appear on the surface of their decking. 

What Are Grooved Plastic-Wood Decks?

A grooved composite decking is a board that has furrow or channel at its sides.

It is because of this furrow or channel that it is called a grooved deck.

To identify a grooved deck, get a deck, and use your fingers to feel the side of the board. If there are hollows at the sides, then it is a grooved deck. 

The grooved deck made it possible to install composite decks without using nails.

It means that hidden fasteners are utilized when fixing grooved decking to the frame. This delivers a remedy to the issue of the nail and screws top appearing on the composite decking surface. 

When hidden fasteners are utilized in installing composite decking, the decking will have a smooth finish.

Using grooved decking also help with safety because you won’t have to deal with nails pushing out of the decks after prolonged use. 

Why Are Grooved and Ungrooved Decking Used?

Grooved and ungrooved decks have their various uses today. Ungrooved decks are better for installing double-story decking.

This is because they don’t have much space in between them, so water will be able to run smoothly without falling to the deck below.

Grooved decking, on the other hand, is preferred because of the good finish that they give when they are used. 


Grooved and ungrooved composite decking boards are used to make composite decking because of the benefits they offered.
