AluZinc AZ150 is an alloy coating consisting of 55% aluminum, 43.4% zinc and 1.6% silicon, and is also known as Galvalume steel, GL steel. AZ150 refers to a coating weight of 150 g/m2 (total of both sides, i.e., average of 75 g/m2 on each side), which belongs to the high-coating quantity, super-protective grade of Aluminum-Zinc Alloy Coating. Steel.

Surface Finish
AluZinc AZ150 has a silver-white matte appearance, because it contains silicon elements that inhibit the formation of zinc crystals, so the surface does not have the “zinc spangle” texture of traditional galvanizing, and presents a uniform and delicate matte effect coating uniformity and good corrosion resistance.
Of course, to improve corrosion resistance, paintability or functionality, surface treatments can be applied to zinc-aluminized steel, including: chemical passivation, fingerprint-resistant treatment, oiling, phosphating, etc.
- Chemical passivation: prevents white rust
- Fingerprint-resistant treatment: keeps the surface clean and aesthetic.
Mechanical Properties
- Mechanical properties of AluZinc steel are determined by the grade of the substrate
- Yield strength ReH: 250-350 MPa
- Tensile strength Rm: 320-450 MPa
- Elongation A80
Performance Certifications
- Corrosion resistance: Evaluated by salt spray test (e.g. ISO 9227 NSS, ASTM B117, ISO 8565).
- Corrosion resistance to cuts: Tested by scratch salt spray test.
- Adhesion / Processability: Verified by bending test, impact test (ISO 6272), T-bend test (after color coating), etc.
- Heat reflectivity: ASTM E903, ASTM C1549.
Further Processing
- Raw Material Processing: Aluzinc steel can be curled, flattened, slit, bent, formed, stamped, welded, and the finished products are aluzinc coil, aluzinc sheet, aluzinc roofing, aluzinc embossed sheet, and ect.
- Paint Processing: Aluzinc steel Paint treatment: AZ100-AZ150 as the substrate roller coating PE/SMP/PVDF/HDP/PU and other materials, the finished product has painted aluzinc coil, painted aluzinc sheet, painted aluzinc roofing etc.
Overwhelming Advantages and Applications of AluZinc AZ150
AZ150 has overwhelming advantages in resistance to atmospheric corrosion, notch corrosion, weathering, heat reflectivity, and design life for a wide range of applications in the construction, industrial, appliance manufacturing, and energy sectors that require a long, low-maintenance service life in harsh environments, especially coastal, industrial, and high humidity environments.
Benefits
Exceptional corrosion resistance:
- 3-6 times more galvanized: AZ150 has a much longer corrosion life than pure zinc, even more than twice as long as Z275, for the same plating weight and in harsh environments (e.g. industrial, coastal, high humidity).
Superior weathering:
- The +55% aluminum content of the AZ150 coating gives it excellent UV resistance and color stability, resulting in long term aesthetics and reduced maintenance requirements.
Excellent heat resistance:
- The oxidative stability of the aluminum gives it good protection at higher temperatures (e.g. roofs in direct sunlight) than pure zinc.
Excellent cut edge protection:
- Aluzinc has a unique “self-healing” property. At scratches and cut edges, it forms a dense corrosion product that slows the spread of red rust to the interior of the steel sheet.
Excellent Heat Reflectivity:
- Aluzinc’s bright white surface has a high solar reflectivity. It reflects most of the solar radiation and effectively reduces the internal temperature of the building.
Good processing and molding properties:
- Suitable for a variety of roll forming, stamping, bending and other processing, not easy to appear plating flaking or chalking.
Adaptability to coating:
- Uniform and clean surface is the ideal color coated substrate, which can be perfectly combined with various high-performance coatings (PVDF, SMP, PE/Polyester, etc.) to form a color coated aluzinc steel (PPGL steel).
Excellent resistance to oxidation at high temperatures:
- At higher temperatures, the aluminum-zinc coating’s resistance to oxidative discoloration and peeling is superior to that of pure zinc coatings.
Economical and long-life value:
- has a service life of 25 years or more and is lightweight.
Application Scenarios
- Building Roof and Wall Systems: Large industrial plants, logistics warehouses, commercial complexes, public buildings (airports, stadiums).
- High-end civil roofing: villas, high-grade housing.
- Severe industrial environments: chemical parks, coastal facilities, internal and external components (such as purlins, wall beams, ventilation ducts) of plants with high humidity.
- Agricultural buildings: Livestock farms, greenhouses.
- Photovoltaic racking systems.
- Electrical enclosures and ventilation ducts.
