Structural Steel AZ150 Galvalume Steel Coil Anti-Finger Print
G550 high-strength Aluzinc steel strip, also known as Galvalume, is a popular material in the Australian market due to its exceptional mechanical properties and durability. This steel grade is characterised by a high tensile strength of 550 MPa, combined with the superior corrosion resistance provided by its aluminium-zinc alloy coating. This makes G550 an ideal choice for demanding applications across various industries.
1. High Strength:
- The G550 grade offers a minimum yield strength of 550 MPa, providing exceptional load-bearing capacity and structural integrity.
2. Corrosion Resistance:
- The aluminium-zinc alloy coating, typically consisting of 55% aluminium, 43.4% zinc, and 1.6% silicon, offers superior corrosion resistance compared to traditional galvanised steel. This makes it ideal for use in harsh environments.
3. Durability:
- The combination of high strength and excellent corrosion resistance ensures a long service life, reducing maintenance costs and downtime.
4. Thermal Reflectivity:
- The high aluminium content provides excellent thermal reflectivity, which can contribute to energy savings in certain applications, such as roofing and cladding.
5. Aesthetic Appeal:
- The smooth, shiny surface of Aluzinc steel is visually appealing and can be used in applications where appearance is important.
1. Construction Industry:
- Roofing and Cladding:
G550 Aluzinc steel is widely used for roofing and cladding in both residential and commercial buildings due to its strength and resistance to the elements. The material’s high strength allows for lighter and longer spans, making it cost-effective.
- Structural Components:
Its high tensile strength makes it suitable for structural components such as purlins, girts, and framing systems.
2. Automotive Industry:
- Body Panels:
G550 Aluzinc steel is used in the automotive industry for body panels and structural parts, where high strength and corrosion resistance are crucial for vehicle safety and longevity.
3. Agricultural Sector:
- Silos and Storage Tanks:
The corrosion-resistant properties of Aluzinc steel make it ideal for silos and storage tanks, which are exposed to harsh environmental conditions and corrosive substances.
- Fencing and Enclosures:
The material is also used for fencing and enclosures, providing long-lasting protection against the elements.
4. Industrial Applications:
- HVAC Systems:
In the HVAC industry, G550 Aluzinc steel is used for ducting and other components that require high strength and corrosion resistance.
- Equipment Housing:
The material’s durability makes it suitable for housing industrial equipment, protecting it from environmental damage.
5. Transport Industry:
- Trailers and Truck Bodies:
G550 Aluzinc steel is used in the manufacture of trailers and truck bodies, where high strength and resistance to road salt and weathering are essential.
1. Climate Suitability:
- The Australian climate can be harsh, with high levels of UV radiation, coastal salt spray, and extreme weather conditions. G550 Aluzinc steel’s corrosion resistance and thermal reflectivity make it well-suited to these environments.
2. Economic Benefits:
- The durability and low maintenance requirements of G550 Aluzinc steel translate to long-term cost savings, making it an economically attractive option for many industries.
3. Regulatory Compliance:
- G550 Aluzinc steel meets Australian standards for construction and manufacturing, ensuring compliance with local regulations and industry requirements.
G550 high-strength Aluzinc steel strip is a versatile and robust material widely used across various industries in Australia. Its superior strength, corrosion resistance, and thermal reflectivity make it an ideal choice for applications in construction, automotive, agriculture, industrial, and transport sectors. The material’s suitability to the Australian climate and its economic benefits further enhance its appeal in the market.

| SURFACE TREATMENT | DESCRIPTION OF USE |
| CHROMATE PASSIVATION(C) | Surface treatment for high-strength steel plates after hot-dip plating to reduce white rust during transport and storage |
| Chrome-free passivation(C5) | Surface treatments that require limiting the amount of hexavalent chromium, etc. in passivation solutions that are harmful to the environment and humans |
| Anti-finger print(N) | Surface treatment after the passivation process, which acts as a lubricant during processing, prevents fingerprints from staining during operation, and prevents premature blackening of the surface during use. |
| Chrome-free and fingerprint resistant(N5) | Surface treatment after the passivation process, in the process of lubrication, to prevent the operation of the fingerprint staining, to prevent the use of the surface of the process of premature blackening, and at the same time, the requirement to limit the fingerprint-resistant film harmful to the environment and human body, such as hexavalent chromium content |
| Oiled(O) | Surface treatment added after the passivation process to further reduce rusting during long-distance transport and long-term storage |
