PaperShell introduces Wood Metal® Sinus – a bio-based alternative to corrugated steel for large-scale architecture applications
PaperShell announces the launch of Wood Metal® Sinus, a trademarked biobased composite material developed as a high-performance alternative to corrugated metal in architecture and construction. Wood Metal® Sinus is made from 100% fossil-carbon-free content, and its record low carbon fooprint delivers an order-of-magnitude improvement on CO2e redcution over traditional facade materials.
Compared to a corrugated steel facade produced in Europe carrying up to 6–10 kg CO₂e per square meter, WoodMetal® Sinus delivers a radically lower footprint without compromising performance. The high-strength, fiber-based composite panel is pressed into a sinus profile that delivers mechanical efficiency while offering a warm, natural aesthetic suitable for both interior and exterior applications.
PaperShell will begin supplying Wood Metal® Sinus to early customers in 2026, with targeted applications in facades, wall systems and structural components. The material is engineered for scalable deployment in mid- and large-scale projects across globally.
“The corrugated profile is one of the most recognisable shapes in industrial history,” says Anders Breitholtz, CEO of PaperShell. “It built railways, factories, harbours — it industrialised continents. Two centuries later, we honour one of the industrial revolution’s most iconic inventions.”
To meet growing demand for fossil-free materials in construction and beyond, PaperShell is preparing a major expansion of its Tibro-based manufacturing site. The facility will host automated, modular composite production lines for components used in construction, transport, consumer goods, electronics and defence. The expansion, suported by a €83.2 million planned investment under the EU Innovation Fund (IF24), will scale PaperShell’s factory to an annual capacity of approximately 23,000 tonnes by 2030, enabling the company to deliver verified climate benefits at large industrial scale.
