Plastic Film-Laminated Steel Sheets

Polyester-based plastic film-laminated steel sheets

EXUM incorporates galvanized steel sheets, stainless steel sheets, and aluminum alloy sheets as a base material. EXUM is a polyester-based plastic film-laminated steel sheet manufactured by our multi-layer extrusion technology.
This material is primarily used in interior applications due to the combination of metal strength, workability, and design qualities.


  • EXUM has a surface hardness higher than PVC film and polyolefin film.
    Many options are available including solid colors, printed patterns, high-gloss options to satisfy various design requirements.
  • This material has excellent bending properties.
  • EXUM can have a vivid appearance with the mirror finish.
  • Emboss
  • High-Gloss
