The panel is available in multiple sizes, from 300×300 mm to 600×1500 mm, and in several surface types: high gloss, coarse texture, wood grain, brushed texture, special-shape and sound-absorbing variants. The material is formed through high-temperature de-moulding and one-piece on-line lamination, providing a scratch-resistant, washable, dimensionally stable surface.

The GFK panel composition includes glass fiber, flame-retardant resin, aluminium hydroxide and silver-containing antibacterial agents. According to the company, the panel achieves Class A2 fire-resistance rating, antibacterial rate above 99.9%, Class 1 mildew resistance, acid-alkali and oxidization resistance, and a 25-year service life. It provides both thermal and sound insulation and can reduce power consumption by 15% due to its thermal insulation performance.

Zhejiang Aobang introduced industrial GFK product technology from Germany in 2010, then developed proprietary GFK technologies through independent R&D.
