Solid M-type WPC Decking 140×23mm

Co-extrusion WPC Deking is the second generation of WPC decking, which is uniformly and firmly covered with protective layer of polymer material around. The protective layer and core layer are successfully extruded under high temperature without adhesive. The inner material is made of high density polyethylene (HDPE) and good quality wood fiber, which is more durable and recyclable. This solid 140mm*23mm board features an arch-shaped groove design, providing exceptional slip resistance and a striking visual appeal. The protective layer adopts advanced macromolecular engineering materials with advanced technology, unique formula and durability.

What is WPC Solid Decking M-Type?

WPC Solid Decking M-Type is a premium category of Co-Extrusion Decking designed for outdoor environments that require high durability, slip resistance, and long-term stability. Compared with traditional wood decking, WPC (Wood Plastic Composite) decking combines natural wood fibers with high-density polyethylene to create a material that is both environmentally friendly and highly resistant to weathering.

The U-timber WPC Solid Decking M-Type adopts advanced co-extrusion technology, which forms a protective polymer layer around the entire board. This outer layer protects the core material from moisture, UV exposure, stains, and daily wear. As a result, the decking maintains its appearance and structural integrity even after years of outdoor use.

With its 140×23 mm solid profile, this board provides higher load-bearing capacity and excellent structural stability, making it suitable for residential and commercial outdoor flooring projects.

Key Advantages of U-timber WPC Solid Decking M-Type

1. Superior Durability

The solid structure of WPC Solid Decking M-Type provides exceptional strength and resistance to cracking, warping, and deformation. The protective co-extrusion layer further enhances durability by preventing water penetration and UV damage.

2. Excellent Slip Resistance

The unique M-type arch groove design improves friction on the surface, offering enhanced safety in wet outdoor environments such as pool decks, terraces, and garden walkways.

3. Weather and UV Resistance

As a high-performance Co-Extrusion Decking, the outer polymer layer effectively protects the board from fading, stains, mold, and mildew caused by sunlight and rain.

4. Eco-Friendly Material

The U-timber WPC Solid Decking M-Type is manufactured using recyclable materials including wood fiber and HDPE plastic, helping reduce deforestation and promoting sustainable construction practices.

5. Low Maintenance

Unlike traditional timber decking, WPC Solid Decking M-Type does not require painting, sealing, or oiling. Regular cleaning with water is sufficient to keep the deck looking new.

Applications of WPC Solid Decking M-Type

Due to its excellent performance and elegant appearance, WPC Solid Decking M-Type is widely used in various outdoor spaces, including:

  • Residential gardens and courtyards

  • Outdoor terraces and patios

  • Balconies and rooftop decks
