Commercial grade refers to a type of decking product that is designed and manufactured to meet the specific needs of commercial applications, such as parks, hotels, and other high-traffic areas. Commercial grade composite decking typically features a more durable and heavy-duty construction than residential grade decking, with higher load capacities and greater resistance to wear and tear.

Commercial grade composite decking may be made from higher quality materials, such as thicker boards or more advanced polymer composites, and may be subject to more rigorous testing and quality control standards than residential grade products. This can result in a higher price point for commercial grade composite decking, but also a longer lifespan and lower maintenance requirements over time, making it a cost-effective choice for commercial settings.
