WPC Decking Joist

WPC Decking Joist – Strong & Durable Support for Composite Decking

The base of your deck is just as important as the top if you want it to last. Everdur New Material Technology Co., Ltd.'s WPC Decking Joist provides commercial-grade structure support that is designed to last for a long time outside. We guarantee a steady supply for your projects with more than 50 production lines and a capacity of more than 1,500 containers per year. Our joists are made of a wood-plastic hybrid material that is very resistant to wetness and insects. Everdur's WPC joists are trusted by more than 225 clients around the world and have been exported to more than 60 countries. They are the solid foundation your decking system needs, and they come with 15–20 year warranties and standards such as ISO 9001, CE, FSC, and REACH compliance.

What Makes Our WPC Joists Different?

You should have a strong base that won't fail you. Second-generation co-extrusion technology is used to make our WPC Decking Joist goods. This means that they will last longer and be less affected by weather than standard wooden supports.

Strong load-bearing ability keeps your deck steady even when a lot of people walk on it and use outdoor furniture. These joists can hold the weight of both a small patio for a home and a large pier for a business.

The great thing about wood-plastic hybrid materials is that they don't get damaged by water, decay, or bugs. You won't have to worry about rot, cracking, or pest damage that come with real wood. The dimensions of our joists stay stable even when temperatures change a lot.

Because they are stable in UV light and keep their color, they work year after year without fading or breaking down. The best part is that it doesn't need much care. It doesn't need to be painted, stained, or sealed. At any time.

We use Grade A reclaimed HDPE mixed with natural wood fiber and chemicals that make it work better. This recipe is good for the environment and supports green building practices while still providing professional-level results.

Performance Features You Can Count On

The weather will be rough for your outdoor projects. The supports we use are made to handle them.

Construction that is waterproof and weather-resistant means that it won't swell or break down in the rain, snow, or heat. Not even after years of being outside, it hasn't cracked, warped, or split.

Mold, mildew, and insects can't hurt these boards, so they stay strong where wood would fail. They stay the same in all kinds of weather, from freezing winters to hot summers.

It is easy to install because it works with normal decking boards and fence systems. The lightweight design speeds up your project timeline without losing strength, and the pre-cut standard lengths make it easy to handle.

Based on how much weight you need to carry, you can choose between empty or solid constructions. Both choices work perfectly with clips, screws, and modular methods for putting things together.
