Environmental friendly products

Wood-Plastic-Composite (WPC) is made of both wood powder and plastic. It uses recycled materials, turns wastes into goods. It saves forests while still offering consumers the appearance and texture of real wood.


Durable and Maintenance-free

WPC is very strong and durable. It is highly resistant to damages from water, UV, termite and rodent. It does not need to be painted and will not rot.

A wide selection of profiles

We have a wide selection of profiles and will help you to choose the most suitable designs. In addition, we can produce customized profiles for your project.
