Introduction to galvanized steel coil

Alu-zinc steel coil is an alloy material with zinc as the base and aluminum as the surface coating. Here are some key information about galvanized steel coil:
Basic composition and structure
Composition ratio: It is mainly composed of 55% aluminum, 43% zinc and 2% silicon solidified at a high temperature of 600℃ to form a dense quaternary crystalline alloy.
Microstructure: Its microstructure is composed of aluminum-iron-silicon-zinc. This special structure gives it unique properties.
Features
Excellent corrosion resistance: When the aluminum layer on the surface is worn by zinc, it can form a dense layer of aluminum oxide to prevent corrosive substances from further corroding the interior. It can effectively resist damage such as acid rain under various climatic conditions, which is 3 times that of pure galvanized sheet.
Good heat resistance: It has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is similar to the high temperature oxidation resistance of aluminum-plated steel sheets. It is often used in chimney pipes, ovens, lighting devices and fluorescent lamp covers.
High thermal reflectivity: The thermal reflectivity is very high, twice that of galvanized steel sheet, so it is often used as a heat insulation material.
Strong economic efficiency: The density of 55% AL-Zn is lower than that of Zn, so under the same weight and the same thickness of the gold-plated layer, the area of ​​​​aluminum-zinc coil is more than 3% larger than that of galvanized coil.
Easy to process and install: It can be processed by various processing methods such as hot-dip galvanizing equipment, cold rolling equipment and rolling equipment to meet the use requirements of different occasions, and the installation is simple and convenient. It can be easily and quickly installed on the surface of the building through drilling, pasting and other installation methods.
Application field
Construction field: It is widely used in building exterior walls, roofs, ceilings, garages, soundproof walls, pipelines and modular houses. Its good corrosion resistance and weathering resistance can effectively protect the surface of the building from erosion by the natural environment.
Home appliance industry: It can be used in the manufacture of home appliances such as refrigerator back panels, gas stoves, air conditioners, electronic microwave ovens, LCD frames, CRT explosion-proof belts, LED backlights, electrical cabinets, etc. Its excellent surface coating performance and anti-corrosion performance make the product more beautiful and durable.
Automotive industry: used in the manufacture of automotive parts such as mufflers, exhaust pipes, carriages, wiper accessories, fuel tanks, truck boxes, etc. High strength and corrosion resistance help improve the safety and service life of the car.
Agricultural field: plays an important role in agricultural production environments such as pig houses, chicken houses, granaries, and greenhouse pipes.
In summary, galvanized steel coils have been widely used in many fields due to their excellent performance. With the continuous expansion of market demand and the continuous advancement of industrial technology, the application prospects of galvanized steel coils will be broader.
