Product catalog summary

Product Overview: The document details the specifications and standards for PolyVision's CeramicSteel panels, which consist of a porcelain-enameled steel face, a medium-density fiberboard core, and an aluminum back. The panels are bonded with hot melt polyurethane adhesive and feature a high-build siloxane edge treatment.

Specifications: The panel has a total thickness of 13.4 mm, with a steel face of 0.56 mm and an aluminum back of 0.4 mm. The core is 12 mm of water-resistant MDF. The panels weigh 26 kg/m² and have a density of 1.9 g/cm³.

Dimensional Tolerances: Length and width tolerances are within 0.1%, and squareness is maintained with a maximum deviation of ±3 mm on a 3000 x 1185 mm panel. Flatness is controlled to a maximum deflection of 0.15%.

Surface Properties: The gloss levels are specified at 65 ± 10 GU at 20° and 60 ± 10 GU at 60°. Color tolerance is ΔE94 ≤ 1.5, with reflectance up to 93% depending on color. The surface is free from defects that could alter appearance, with a Mohs hardness of at least 5 and scratch resistance of at least 7 N.

Durability and Resistance: The panels exhibit high wear resistance, impact resistance, and coating adhesion. They are resistant to cold and boiling acids, UV exposure, and graffiti, with no significant color or gloss change after cleaning.

Compliance and Standards: The panels conform to ISO 28722, EEA 7.13, 7.14, EN 14431, and PEI 1001 standards, ensuring high quality and durability for architectural applications.
