政泰彩石金屬瓦是由鍍鋁鋅鋼板作為基材、彩色砂粒、底漆和丙烯酸樹脂構(gòu)成。其中鍍鋁鋅鋼板基材是由55%鋁，43.4%鋅和1.6%硅組成的電鍍液經(jīng)電鍍而成的，其加工性、涂裝性與鍍鋅鋼板基本相同。彩色砂粒是金屬瓦的裝飾層及基層保護層，它是由一定粒徑的顆粒經(jīng)高科技著色工藝和高溫烤制而成的。具有十多種顏色，可耐紫外線照射，能減輕雨水給金屬瓦造成的噪音，使彩色鋼板瓦色彩豐富莊重，裝飾性更好，這是一般彩色壓型鋼板所不具備，也是不能比的。底漆作為瓦的特殊材料，它是使鍍鋁鋅鋼板與彩色砂粒進行良好粘結(jié)的材料，作用大。而丙烯酸樹脂作為表面的保護層，防止細部雨水滲漏，能延長砂粒色彩的壽命。
