LHMA004 is a WPC load-bearing joist specifically developed for WPC decking systems. It offers consistent weather resistance and anti-corrosion performance. The top features precision grooved tracks that perfectly match the dedicated decking clips. During installation, it is securely connected to the ground using countersunk self-tapping screws and expansion anchors, with screw heads sitting below the joist surface to achieve concealed installation with no exposed screws. It is suitable for various high-traffic, high-load-bearing outdoor and semi-outdoor decking projects.

1. Strong Load-Bearing with Lightweight Design

The optimized cross-section design provides high load-bearing capacity and impact resistance while effectively reducing self-weight. It is suitable for load-sensitive applications such as rooftops and high-rise terraces, and is also easy to handle and install.

2. Concealed Installation, Aesthetic and Durable

The top features precision grooved tracks that perfectly match the dedicated decking clips. After installation, the screws are fully concealed inside the joist, leaving no exposed screw holes on the surface. This improves the overall appearance and prevents screw rust from affecting service life.

3. Moisture & Rot Resistant, WPC-Matching Lifespan

The material is waterproof, moisture-proof, insect-resistant, termite-resistant, and weather-resistant. It will not rot, crack, or warp, and can withstand harsh outdoor environments with moisture and alternating hot and cold temperatures, significantly reducing later maintenance costs.

4. Strong System Compatibility and Wide Application

As part of the original factory-matched system, it is perfectly compatible with series of WPC decking. It is widely used in wetland park trails, roof gardens, commercial terraces, and high-traffic public areas, making it a reliable foundation for building high-quality outdoor WPC platforms.

As a matching load-bearing joist for WPC decking systems, LHMA004 is suitable for a wide range of outdoor and semi-outdoor elevated WPC decking projects includes :

Landscape walkways: wetland park trails, garden paths, courtyard walkways, waterfront boardwalks;

Elevated platforms: roof gardens, terraces, balconies;

Commercial spaces: café terraces, restaurant outdoor seating, high-end retail outdoor areas, hotel and resort poolside areas;

Public areas: parks, plazas, pedestrian streets, high-traffic public walkways and rest areas;

Renovation projects: upgrades of old wooden decks, balconies, boardwalks, and other outdoor areas.
