Titanium-zinc plate is a new type of high-grade aluminum-plastic plate building material made of titanium-zinc alloy plate as the panel, 3003H26 (H24) aluminum plate as the back plate, high-pressure low-density polyethylene (LDPE) as the core material, and thermally compounded. Combining the characteristics of the titanium-zinc plate (metal texture, surface self-repairing function, long service life, good plasticity, etc.) with the advantages of flatness and high bending resistance of the composite plate, it is a model of the combination of classical art and modern technology.
