General Questions

Who is RAINBODECK?

• RAINBODECK is a leading composite materials brand and the pioneer in the HPC (High-Performance Composite) industry. 
  

What is RAINBODECK HPC made of?

• HPC (High-Performance Composite) is made from recycled single-polymer HDPE and recycled wood, creating a sustainable, safe, healthy, and high-quality material specifically engineered for outdoor applications.
  

What is CoShield™ technology?

• CoShield™ is an enhanced HPC variant featuring a co-extrusion process. This adds a wood-free, moisture-proof, and stain-resistant layer to the HPC core. The layer is neither decorative paper nor coating, but integrated via a glue-free, non-laminating extrusion method. As a bonded part of HPC, it will not delaminate or separate.
  

• CoShield™’s TCT (Twin-Color Technology) enables two optional colors per board, with vivid mixed hues and 3D wood-grain embossing for authentic natural wood aesthetics.
  

• Additionally, its industry-leading Class C & R11 anti-slip surface meets strict commercial safety standards.
