What’s the difference between standard and heavy duty deck boards?
Standard composite deck boards are suitable for most commercial and domestic applications. They are made from wood fibres and recycled plastic, offering high levels of durability, practicality, and quality. Ecodek composite boards have a solid core, making them a reliable choice for most decking projects.
Heavy-duty composite deck boards are made in the same way but have a deeper profile. This provides the strength needed to withstand high levels of foot traffic, making them ideal for demanding commercial spaces.
