Class A anodized aluminum sandwich panel is made up of two layers of aluminum plate and mineral filler. Its fireproof class is in compliance with EN13501-1:2007+A1:2009 and GB8624 - 2012 standard. Compared with aluminum plate, the class A anodized aluminum sandwich panel has a richer surface selectivity and the construction and processing performance is as same as the common aluminum sandwich panels. So that architects have more possibilities to innovate.
