1. The disadvantage of aluminum plate is its insufficient deformation resistance; Poor waterproof and sealing performance; The thermal conductivity is very high, and the thermal insulation performance is poor. The price is high, and it is very troublesome to process semi-finished products in the factory and transport them to the construction site.

2. The disadvantage of aluminum-plastic board is that the curtain wall system has poor deformation resistance, low strength and poor heat resistance, and the overall strength and safety of the processed aluminum-plastic board cannot be guaranteed.

The unique performance of aluminum-plastic composite board determines its wide application. It can be used for building exterior walls, curtain wall panels, old building renovation, indoor wall and ceiling decoration, advertising signs, display racks, and dust purification projects. Belonging to a novel building decoration material.
