Introduction for 55% galvalume aluzinc steel coil
55% galvalume aluzinc steel coil is an important alloy material often used in daily life. Alu-zinc steel sheet is composed of an aluminum-zinc alloy structure, composed of 55% aluminum, 43% zinc, and 2% silicon solidified at a high temperature of 600 degree . Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal alloy.
55% galvalume aluzinc steel coil has many excellent properties: strong corrosion resistance, which is 3 times that of pure galvanized sheet; beautiful zinc flowers on the surface, which can be used as building exterior panels. The corrosion resistance of "galvanized steel coil" is mainly due to aluminum, which has a protective function. When zinc is worn, aluminum forms a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.
Roll up - pretreatment - passivation - initial coating - drying - cooling - fine coating - drying - cooling - roll down.
The product packaging is by the export fine packaging standards, including galvanized outer packaging, moisture-proof paper, waterproof film, paper tube or iron barrel, galvanized packing tape, desiccant, aluminum side guardrail, and wooden pallet.
