Our hard stiffness grey board is a heavy-duty, dimensionally stable rigid paperboard engineered for applications that demand superior load-bearing capacity and long-term shape retention. With a thickness range of 1.2mm to 4.3mm, this uncoated grey chipboard (also known as rigid grey paperboard, heavy-duty chipboard, or packaging board) is specially formulated to deliver exceptional bending resistance and anti-warping performance, making it the ideal substrate for high-quality paper hangers, heavy-duty packaging, and structural applications. Manufactured from recycled mixed pulp, our grey board combines eco-friendly production with uncompromising rigidity, trusted by garment industry suppliers, premium packaging producers, and retail product manufacturers for consistent, reliable performance in high-volume production. Every batch undergoes rigorous stiffness testing to ensure it meets the strict load requirements of paper hanger and heavy packaging applications, with no sagging or deformation under sustained weight.

Designed for cost-sensitive, mid-tier production, our A Grade grey board offers standard stiffness and a basic kraft finish, suitable for low to mid-weight paper hangers and domestic bulk packaging applications with moderate load requirements.
Our mid-to-high tier AA Grade hard stiffness grey board features a smooth double-sided grey finish, enhanced bending resistance, and consistent dimensional stability. It is optimized for mid-weight paper hangers, rigid folding cartons, and retail display applications that demand reliable rigidity and a clean finish.
For heavy-duty, high-performance applications, our top-tier AAA Grade high stiffness grey paperboard delivers industry-leading hardness, exceptional load-bearing capacity, and a bright grey ultra-smooth surface. It is purpose-built for heavy-duty paper hangers, luxury rigid packaging, puzzle bases, and other applications that require maximum anti-deformation performance and long-term structural integrity.
Our core specialty is manufacturing the ideal substrate for heavy-duty paper hangers for the garment and retail industry, but our rigid grey board excels across a wide range of professional structural applications:
Garment & Retail: High-load paper hangers, retail display stands, and point-of-sale (POS) displays
Premium & Industrial Packaging: Luxury gift boxes, wine and spirit rigid packaging, heavy-duty folding cartons, and product shipping inserts
Art & Framing: Artwork mounting boards, poster backing, and framed print support boards
Craft & Manufacturing: Board game and puzzle bases, scale model making, and DIY structural projects requiring superior rigidity
