Introduction
UPM ProFi® Deck is an innovative composite material combining plastic and engineered fibers, primarily sourced from surplus by-products of self-adhesive label manufacturing. It is environmentally friendly, lignin-free, and contains no harmful chemicals.

Material and Structure
The material is a hollow composite profile produced using extrusion technology. It is available in standard lengths of 4.0 meters, with custom lengths ranging from 2.0 to 6.0 meters upon request. The dimensions and weight for various components are specified, with tolerances for length, width, and thickness.

Physical and Mechanical Properties
Key properties include a density of 1.2 g/cm³, bending strength of 13 N/mm², and high impact resistance at both +23°C and -20°C. The surface hardness is 28 N/mm², and the material exhibits excellent wear resistance and slip resistance. It is classified as fire class E and is resistant to European termites. The thermal expansion coefficient is 4.0 x 10^-5 1/°C, with a heat transfer coefficient of 0.24 W/mK. Water absorption and swelling are minimal.

Environmental Impact
UPM ProFi Deck reduces landfill and waste incineration by utilizing label surplus material. The only added plastic is clean polypropylene, and production waste can be recycled. The material can be disposed of with household waste for energy conversion.

Thermal Expansion
UPM ProFi Deck expands and contracts with temperature changes. A table illustrates the expansion/shrinkage for boards of different lengths at various temperature changes. The expansion coefficient is 0.040 mm per 1°C per 1 m length.

Colour Weathering and Maintenance
Unlike conventional decks, UPM ProFi Deck is virtually lignin-free, preventing typical greying. Colors may fade slightly over time, especially in high UV areas. Regular cleaning with a hose or brush is recommended to maintain color and prevent dirt accumulation. The surface is resistant to moisture absorption and stains, with simple cleaning methods usually sufficient.

Conclusion
UPM ProFi Deck offers a sustainable, durable, and low-maintenance decking solution. For the most updated information, visit the official website.
