Description
ASTM A653/A653M G90 1.2*1000mm Mill Edge Galvanized Steel Coil For Automotive Industry
ASTM A653/A653M G90 is a specific designation within the ASTM A653/A653M standard for hot-dipped galvanized steel sheets and coils. It refers to the coating weight or amount of zinc applied to the surface of the steel.
The "G90" designation indicates a coating weight of 0.90 ounces per square foot (oz/ft²) or approximately 275 grams per square meter (g/m²). This means that for every square foot of galvanized steel, there is a coating of zinc weighing 0.90 ounces.
G90 is considered a relatively heavy coating weight, providing a high level of corrosion protection for the underlying steel. The zinc coating acts as a sacrificial barrier, preventing the steel substrate from coming into direct contact with corrosive elements in the environment. It helps to extend the lifespan of the steel and maintain its structural integrity.
It's important to note that the actual thickness of the zinc coating may vary slightly within the G90 range, but the average coating weight must meet the specified value. The coating thickness is often measured using methods such as magnetic thickness gauges or weight-based calculations.

Application
Automotive Industry: G90 galvanized steel is used in automotive manufacturing for various components, including body panels, chassis parts, and reinforcements. The corrosion resistance of G90 helps to extend the lifespan of automotive parts and improves their overall durability.
Building and Construction: G90 galvanized steel is widely used in the construction industry for roofing, siding, and structural components. It provides long-lasting protection against corrosion and helps to maintain the structural integrity of buildings.
Agricultural Equipment: G90 galvanized steel finds applications in the agricultural sector for equipment such as grain bins, silos, and farm machinery. The corrosion resistance of G90 helps to protect these structures from the exposure to agricultural chemicals and environmental conditions.
HVAC Systems: G90 galvanized steel is used in heating, ventilation, and air conditioning (HVAC) systems, including ductwork and HVAC components. It provides corrosion resistance in the high-moisture environments typically found in HVAC installations.
FAQ
Q1: Do you accept or not accept galvanized coating testing?
A1: Yes, tested for zinc coatings. We can send galvanized steel coil samples to the laboratory required by customers.
Q2: Can galvanized steel coil be oiled?
A2: Yes, it can be oiled. 8-20 grams per square meter. Oiling can prevent oxidation of galvanized sheet in a short time.
Q3: Sometimes, the galvanized coating is shinier in some places than others. Why is that?
A3: The galvanized coating appearance may either be bright and shiny resulting from the presence of an outer layer of pure zinc, or duller, matte gray as the result of the coatings intermetallic layers being exposed. Performance is not affected. Coating appearance depends on the amount of zinc in the coating.
