Prepainted Steel Coil(PPGI, PPGL)

TPO metal composite sheet coil  presentation         

TPO metal composite sheet coil

It is firmly covered on the surface of aluminum coil board by high temperature and high pressure.
We enhance steel coil performance through advanced laminating film technology alongside organic coatings. Our precision coil coating line applies durable laminating films using a thermally activated process: adhesive is heated to 160-180°C and uniformly rolled onto coils, followed by seamless film bonding. This method delivers superior surface properties for specialized applications, including enhanced scratch resistance, weatherproofing, and custom aesthetic finishes.

Specifications:

Why TPO Coated Metal Stands Out ?
All-in-One Performance
- 99.9% water vapor barrier ratio (ASTM E96)
- -40°C to +120°C operational stability (UL 790 certified)
- 25-year UV degradation warranty
Solar-Ready Surface
- Pre-engineered clamp zones for rapid PV panel mounting
- 8-12% increased bifacial solar yield through reflective backing
- Wind uplift resistance up to 90psf (ASCE 7-16 compliant)
