ASTM A653M Galvanized Steel Sheet In Coil
ASTM A653M is a specification standard for hot dip galvanized steel coil, mainly used for thin sheets coated with hot-dip galvanizing.
When it comes to high-quality steel products, hot dip Gl coil ASTM A653M is a standout choice for industries that demand exceptional performance and longevity.
ASTM A653M is a standard developed by the American Society for Testing and Materials (ASTM) for zinc-coated sheets in coils and cut-to-length produced by hot-dip galvanizing.
ASTM A653M is a specification that outlines the requirements for steel sheets coated with zinc (galvanized) through the hot-dip process. This standard ensures that the steel coils provide consistent mechanical properties and coating quality, making them suitable for demanding environments and applications.
| Types of galvanized layers | Hot-dip pure zinc coating (Z) |
|---|---|
| Thickness of the galvanized layer | G30, G90, G235, etc. |
| Chemical composition | C ≤ 0.10%, Mn ≤ 0.60%, P ≤ 0.035%, S ≤ 0.035%, etc. |
Production process
The process of hot dip Gl steel coil is not complicated and can be divided into three parts: pre-treatment, hot-dip galvanizing and post-treatment. The main process flow includes: degreasing (if necessary) → pickling → reduction → water washing → plating aid → drying → hot-dip galvanizing → water cooling → passivation → inspection and packaging → warehousing.
Application
Construction industry
Hot dip Gl steel sheet in coil A653M is used to manufacture building materials such as light steel structures, metal roof tiles, corrugated sheets, sandwich panels, etc., with excellent corrosion resistance and structural strength; hot dipped galvanized coil a653m is used in pipeline system linings, culvert pipes, door and window reinforcement profiles and metal components of building insulation systems.
Automobile manufacturing
Hot dipped galvanized steel coil a653m is used as a raw material for internal and external parts of the car body, including body repair parts for public transportation vehicles (such as buses and trams); hot dipped Gl steel coil a653m is often used in the production of high-strength automotive steel coils to meet the automotive industry's requirements for surface quality and forming performance.
Mechanical manufacturing and home appliances
Hot dipped Gl steel sheet In Coil a653m is made into protective structures for electrical equipment housings, household appliance components (such as washing machines, refrigerators) and metering devices; it can be used to produce high-strength galvanized substrates for daily necessities such as tableware and containers.
Industrial extended applications
Prime hot dipped galvanized steel coil a653m is used as a substrate for secondary processing materials such as color coated steel plates, expanding the scope of application of coating processes.
