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.
Key Characteristics
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.
Uses of Slit Aluminized Zinc-Coated Steel Strips
Slit aluminized zinc-coated steel strips, also known as Galvalume strips, are widely used in various industries due to their excellent corrosion resistance, heat reflectivity, and aesthetic appearance. Some of the key applications include:
1. Construction Industry:
- Roofing and Cladding: These strips are commonly used in roofing panels, siding, and wall cladding due to their durability and resistance to weathering.
