The sampling varieties include: anodic oxidation coloring profiles, electrophoretic painting profiles, powder coating profiles and thermal insulation profiles. According to the "aluminum alloy building profile product supervision and implementation specifications CCGF301-2008", GB5237.2 ~ .6-2004 mandatory national product standards requirements for testing, mechanical properties, room temperature longitudinal shear characteristic value (heat insulation profiles), surface properties in the composite film local thickness, pencil hardness (electricity), adhesion, coating maximum local thickness, coating indentation hardness and other test indicators. Indicators all qualified. Problems are mainly sealing quality, dimensional deviation (wall thickness), salt spray test, coating the minimum local film thickness, single piece of local film thickness, single piece of the average film thickness, alkali resistance, iron Fe, copper Cu and other items failed.
