Galvanized galvalume Aluminized zinc steel coil

Short Description:

It is suitable for computer case, household appliances peripheral equipment, satellite dish, color coated substrate, drain pipe, roll door, automobile parts, galvanized welded pipe, structural pipe, water pipe, etc.
Aluminum – zinc – coated steel coil is an important alloy material which is often used in daily life. Aluminized zinc steel coil is aluminum zinc alloy structure, composed of 55% aluminum, 43% zinc and 2% silicon solidified at 600℃ and its entire structure is composed of aluminum – iron – silicon – zinc, forming a dense quaternary junction crystal of an alloy.

Aluminized zinc steel coil has many excellent characteristics: strong corrosion resistance, is 3 times of pure galvanized coil; The surface has beautiful zinc flowers, which can be used as exterior panels of the building.

Corrosion resistance
The corrosion resistance of "aluminized zinc steel coil" is mainly due to aluminum, aluminum's protective function. When the zinc wears down, the aluminum forms a dense layer of aluminum oxide, preventing the resistance from further corroding the interior.

Heat resistance
Aluminum zinc alloy steel coil has good heat resistance, can withstand the high temperature of 300 degrees Celsius, and aluminum plated steel plate high temperature oxidation resistance is very similar, often used in chimney tubes, ovens, illuminators and daylight lampshades.

Thermal reflectivity
Aluminized zinc steel coil has a high thermal reflectivity, twice that of galvanized steel, and is often used as insulation material.

Because the density of 55%AL-Zn is less than that of Zn, the area of the aluminum-zinc coil is more than 3% larger than that of the steel coil, given the same weight and the same thickness of the gold coating.


Buildings: roofs, walls, garages, sound walls, pipes, combined houses and other.
Cars: mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes and other.
