G90 Galvanized Steel Advantages
1. Excellent corrosion resistance
One of the main advantages of G90 galvanized steel is its excellent corrosion resistance.The zinc layer acts as a barrier to effectively prevent the steel from being eroded by corrosive media in the atmosphere, water, soil and other environments, thereby extending the service life of the steel.
2. Very durable
G90 galvanized steel has both excellent corrosion resistance and high strength characteristics of steel, and can withstand various loads and stresses and maintain stable performance.
3. Good processing performance
G90 galvanized steel has good processing performance and can be processed by longitudinal shearing, cutting, bending, welding and other processing operations to meet the needs of various specifications and shapes.
4. Beautiful appearance
G90 galvanized steel has a smooth and flat surface, with good visual effects and aesthetics.
In addition, G90 galvanized steel can be pre-painted on the surface to obtain a variety of colors (Pre-painted Galvanized Steel Coil) to meet personalized needs.
Application of G90 galvanized steel
Construction field
- Structural components: G90 galvanized steel can be used for structural components such as beams, columns, purlins, etc. of buildings. The 0.9 ounces of galvanizing per square foot can provide excellent corrosion protection and extend the service life.
- Roof and wall panels: In coastal or humid areas, G90 galvanized steel is also widely used for roof and wall cladding to ensure the durability of roofs and wall panels.
Automobile manufacturing field
- Body parts: In the manufacture of body parts, g90 galvanized steel can be used in parts such as doors, roofs, and underbody guards to improve the corrosion resistance and safety of the car.
- Chassis parts: Many parts in the car that need to withstand harsh working environments, such as exhaust systems and fuel tanks, are also often made of G90 galvanized steel to ensure their durability and stability.
Agriculture field
- Agricultural machinery: Used to manufacture parts of agricultural machinery such as tractors and harvesters to withstand the harsh environment in the fields.
- Grain storage and transportation equipment: G90 galvanized steel is used to manufacture grain storage and transportation equipment, such as granaries, feed storage equipment, etc. These equipment need to withstand environmental factors such as moisture and corrosion, and G90 galvanized steel is an ideal choice.
Other fields
- Home appliance manufacturing: The outer shells of home appliances such as refrigerators, washing machines, and air conditioners, as well as internal parts such as brackets and fixings, can be improved by using G90 galvanized steel to improve corrosion resistance and aesthetics.
- Power facilities: Such as electric poles, electric towers, and electrical appliance shells, etc., the use of G90 galvanized steel can improve their corrosion resistance and ensure the safe operation of power facilities.
- Traffic facilities: Such as guardrails, bridges, road signs, etc., the use of G90 galvanized steel can extend the service life and reduce maintenance costs.
G90 VS Z275
G90 Meaning
- G90 represents the coating code in the imperial unit (oz/ft²) under the ASTM 653/653M standard.
- “G” stands for galvanized.”90″ stands for the average minimum weight of the galvanized amount measured at three points on both sides, which is 0.9 ounces.
- The larger the number, the more galvanized the amount and the thicker the zinc layer.Common coating codes: G30, G60, G90, G185, etc.
Z275 Meaning
- Z275 represents the coating code in the metric unit (g/m²) under the EN 10327 standard.
- “Z” stands for galvanized.”275″ stands for galvanized amount of 275g/㎡.
- Similarly, the larger the number, the thicker the zinc layer.Common coating codes: Z30, Z60, Z120, Z275, etc.
Comparison of galvanized amount
After understanding the meaning of G90 and Z275, which one has a higher galvanized amount? Calculated in metric units, the weight of G90 coating is equivalent to about 275g/m² of zinc coating, and the galvanizing amount of the two is basically the same. The calculation method is as follows:
1oz=0.0284kg, 0.9oz=0.02556kg=25.56g, 1ft²=0.093m².
The above results in 0.9oz/ft²=25.56g/0.093m², that is, the galvanizing amount of 0.093 square meter is 25.56g, so the galvanizing amount of 1 square meter is 274.83871g.It verifies that the galvanizing amount of G90 and Z275 is basically the same.
