Benefits
- Excellent flatness: Because of its continuous laminating process, GRAPHIC-ALTM LT is a flat panel without buckles, edge waves and overall warping.
- Continuous color: GRAPHIC-ALTM LT has a paint finish with consistent color produced in our continuous coil coating line.
- High rigidity: GRAPHIC-ALTM LT offers high rigidity in a lightweight material. It is equivalent to 2.2mm thick aluminum sheets and 6.3mm thick acrylic sheets in rigidity.
- Lightweight: GRAPHIC-ALTM LT 3mm is only 0.76psf which is equivalent to 1.4mm aluminum sheets and 3.1mm acrylic sheets.
- Workability: GRAPHIC-ALTM HP is easy to cut, groove, bend and assemble with regular machines and tools widely used in the sign industry.
Material Composition
GRAPHIC-ALTM LT is composed of two skins of 0.010" thick aluminum and polyethylene core. Both top and back surfaces are polyester coatings produced in our continuous coil coating line. Both sides are covered with transparent protective film.
