Comparing 6m Long Decking Boards with Standard Sizes
Composite decking is commonly available in sizes like 2.4m, 3.6m, 4m, and 4.8m. Choosing 6 metre length composite decking boards offers:
Fewer cuts compared to 2.4m or 3.6m boards: Ideal for projects where large spans are needed. Shorter boards may require extra joins, which disrupt the appearance.
Better aesthetics compared to 4m boards: 6m planks reduce the number of visible seams, creating a premium finish.
More efficiency in wide-area installations than 4.8m boards: While 4.8m boards are a good compromise, 6m options cover more space with fewer boards, further cutting down installation time.
Stronger visual impact: Long planks create an uninterrupted “flow” that makes decks appear more expansive and professional.
Commercial advantage: For hotels, resorts, or public projects, 6m lengths provide the durability and look that shorter boards cannot match.
In projects that require a professional, seamless look, 6m decking is the premium choice—balancing functionality, aesthetics, and long-term value.
Materials and Finishes Available
