HDPE decking refers to decking material made from high-density polyethylene, which is a type of petroleum thermoplastic. This material is known for its durability and resistance to wear and tear, making it an ideal option for outdoor decking. It is also resistant to moisture, mold, and mildew, which makes it a low-maintenance option.

Unlike wood, HDPE decking boards do not require sealing or staining to maintain their appearance. This also makes them environmentally friendly since they do not require harmful chemicals for upkeep. Additionally, HDPE decking is resistant to fading and discoloration from exposure to sunlight, ensuring that the deck looks good for years.

China PVC decking is a type of decking material made from polyvinyl chloride, which is also a thermoplastic material. It is lightweight and durable, making it an ideal option for outdoor decking. It is also resistant to moisture, mold, and mildew, which makes it low maintenance.

Overall, both HDPE and PVC decking provide excellent options for outdoor decking that are low maintenance, durable, and resistant to environmental conditions.
