For architects, specifiers, and serious contractors, knowing the exact specifications of a PVC wall panel is essential. This article provides the complete technical profile of WITOP's UV Marble Sheet and UV panel product lines. All data is derived from internal testing following ASTM, ISO, or GB/T standards. Use this information for project specifications, code compliance, and material comparisons.
WITOP manufactures three series of UV sheets for different applications:
Series | Thickness Range | Typical Use | Key Feature |
|---|---|---|---|
WITOP Classic | 2.5mm, 4mm | Residential walls, light commercial | Standard UV coating, 2H hardness |
WITOP Premium | 4mm, 5mm, 6mm | Hospitality, retail, high-traffic | Enhanced UV coating, 3H hardness, anti-fingerprint option |
WITOP FR | 4mm, 5mm, 6mm | Public buildings, healthcare, schools | UL 94 V-0 flame rating, low smoke |
All series are available in UV Marble Sheet designs, solid colors, and wood grains.

Production date and shift code
Access to online test report (scan QR code on packaging)
We maintain samples from every batch for 10 years.
For your project documentation, use this specification language:
“PVC wall panels shall be WITOP Series [Classic/Premium/FR] UV Marble Sheet or approved equal. Panels shall have genuine UV-cured topcoat with minimum 2H pencil hardness (Classic) or 3H (Premium). Printed marble pattern shall be 1440 dpi digital with non-repeating veining. Gloss level shall be 85-95 GU unless specified otherwise. Panels shall meet UL 94 V-2 (Classic) or V-0 (FR) flammability rating. All panels shall be from single production run to ensure color match.”
WITOP provides complete transparency for every PVC wall panel, UV Marble Sheet, UV panel, and UV sheet we manufacture.
