Frequently Asked Questions

A2 (GB 8624 A2 / EN 13501-1 A2-s1,d0) is a nearly non-combustible grade: the mineral core contains no combustible polymer and produces minimal smoke and no flaming droplets. B1 is a flame-retardant grade: the core is formulated to resist flame spread and self-extinguish, but it remains technically combustible. High-rise facades and public buildings usually require A2 by code; B1 suits low-rise exteriors, interiors and signage.

Standard width is 1220 mm with lengths up to 5800 mm (custom lengths on request). Total thickness: 3 / 4 / 5 / 6 mm, with aluminum skin from 0.15 mm to 0.50 mm. Panels can be cut to project-specific sizes.
