Best Types of Dock Decking Material

Dock Decking Material - Rope and Cleat on Dock


Aluminum is a great choice for dock decking because it is maintenance-free and very durable. Aluminum is light-weight, and it will not rust or warp over time like other dock material options. This durable decking option can come in a wide array of different colors and can be powder coated or left raw. If you are looking to reduce the amount of work you put into maintaining your current dock, aluminum is a great choice of material to consider for your dock. The cons to aluminum decking are that it can be expensive and is typical used in commercial and industrial dock settings.

Pressure-treated Wood Decking

Pressure-treated wood decking is a common material for dock decking. Pressure-treated wood is strong and can weather the elements and is a more cost-efficient material than other boat dock deck options. Wood is a beautiful and timeless traditional dock decking material that can last for 25+ years with annual maintenance and care. The cons to pressure-treated wood are that it needs to be maintained and older docks can cause splinters. Pressure-treated woods are more resilient to root than other wood decking alternatives but can warp and bend easily and is susceptible to insect attacks.

Composite Decking

Composite decking is one of the most used decking for boat docks because it is an environmentally friendly lumber substitute. Composite Decking is weather-resistant, stain-resistant, and can come in an array of colors. Composite Decking is lightweight which makes for an easier installation process than other materials. This dock decking material does not splinter or rot like wood and it is a low maintenance option. The cons of composite decking are that they do not look as nice as other options and they can be slippery when wet. Composite decking tends to bend and sag more than other options, but it is low maintenance and a cost-efficient solution to your dock decking needs.


Plastic decking is a lightweight, maintenance-free dock deck material that does not get overly hot in direct sunlight. Plastic docks are easy to assemble and are generally UV resistant, so they look new longer than other dock deck options. They can come in any color with a variety of patterns that makes plastic docks a great non-slip option. The cons of plastic decking are they will start to look worn and old over time and they are not the most eco-friendly option there is.
