JISCO AZ80 Hot-Dip Aluminum-Zinc Coil, SGLCC Aluminized Zinc Sheet – In-Stock Steel for Electrical Enclosure Cabinets

Galvalume Coil (Aluminized Zinc) Product Details

1. Product Overview

Hot-dip Al-Zn coated coil, also known as Aluminized Zinc Steel Coil or GL Al-Zn sheet, is a premium anti-corrosion coated steel produced by continuous hot-dip coating on cold-rolled base metal. It features an alloy coating composed of 55% aluminum, 43.4% zinc, and 1.6% silicon. Offering 3–4 times the corrosion resistance of standard galvanized sheets, it combines heat resistance, reflectivity, and self-healing properties, making it the leading anti-corrosion substrate for construction, appliances, solar energy, and automotive industries.

Shanghai Biying International Trade Co., Ltd. maintains long-term stock of hot-dip aluminum-zinc coils from major domestic mills including Baosteel, JISCO, Angang, Jingye, Tianjie, Pangang, and Shougang. Our mainstream grades cover DX51D+AZ, DX53D+AZ, SGLCC, and G550+AZ. Zinc coating specifications are fully available in AZ80 (80g), AZ120 (120g), AZ150 (150g), and AZ180 (180g). Located in Shanghai, we offer slit-to-width processing, film lamination, and fingerprint-resistant treatment. We support retail sales, bulk wholesale, and export supply.

2. Performance and Application Scenarios of Mainstream Grades

DX51D+AZ (General Molding Grade)

Most popular commercial aluminized zinc coil with excellent bendability and stamping performance. Ideal for factory roofs, perimeter walls, electrical cabinets, and air conditioner outdoor units. Available in AZ80, AZ120, and AZ150 zinc coating options. Mainstream grades from Baosteel, JISCO, and Angang—the most widely purchased hot-dip aluminized zinc sheet on the market.

DX53D+AZ (Deep Drawing/Stretching Grade)

Super deep-drawing performance with crack-free stretching. Ideal for refrigerator back panels, oven casings, and small appliance housings. Optional fingerprint-resistant surface finish available. Full zinc coating from 8g to 18g. Designed for long-term procurement by home appliance manufacturers.

SGLCC (Japanese Standard Galvalume)

Meets JIS G3321 standards; compatible with color-coated base metals, light steel framing, and small equipment enclosures. Available in stock from original manufacturers Baosteel, Shougang, and Pangang. Features high flatness and strong paint adhesion.

G550+AZ (High-Strength Structural Grade)

Yield Strength 550MPa High-Hardness Aluminized Zinc-Coiled Steel: Resists bending and deformation. Designed for PV mounting structures, light steel villas, warehouse purlins, and outdoor load-bearing components. AZ150, AZ180 high-zinc layers for coastal high-corrosion environments.

III. Specifications for Hot-Dip Galvanized Coating

AZ80 (80g/m²): Economical aluzinc coating; ideal for indoor dry environments, temporary structures, and simple equipment enclosures. High cost-performance ratio.

AZ20 (120 g/m²): Standard zinc coating; the top choice for most buildings and appliances under normal operating conditions, offering balanced corrosion resistance and the highest market availability.

AZ150 (150g/m²): Enhanced anti-corrosion coating for outdoor industrial facilities, solar mounting structures, and coastal or inland applications; offers extended weathering durability.

AZ180 (18 0g/m²): Heavy-galvanized corrosion protection for coastal facilities, chemical equipment, and marine applications with significantly enhanced salt spray resistance.

IV. Core Product Advantages

Direct from multiple steel mills: stable quality

Partnered with seven leading steel mills: Baosteel, JISCO, Angang, Jingye, Tianjie, Pangang, and Shougang. Each coil comes with an original mill certificate guaranteeing quality compliance, zero defects, and third-party inspection support. Full customs documentation and material certificates available for export orders.

Ultra-long anti-corrosion service life

55% Al-Zn alloy coating delivers dual-layer protection: the aluminum layer blocks air to prevent oxidation, while the zinc layer acts as a sacrificial anode to repair scratches. This extends outdoor service life far beyond standard galvanized steel and reduces long-term maintenance and repainting costs.

Excellent high-temperature resistance

Withstands temperatures up to 300°C indefinitely. Designed for ovens, heat exchangers, and exhaust systems; resists peeling and flaking in high-heat environments. Outperforms galvanized steel.

One-stop processing solutions

Shanghai-based in-house processing workshop offering customized flat-cutting, slitting into narrow strips, film lamination with fingerprint-resistant coating, shearing, and bending. No need to outsource to external processors—saving procurement and communication costs.

VI. Common Procurement FAQs

Q1: What is the difference between Aluzinc and galvanized steel?

The aluzinc coating contains 55% aluminum, offering corrosion and heat resistance 1–2 times that of galvanized steel. For outdoor and coastal projects, prioritize DX51D+AZ/G550+AZ hot-dip aluzinc coils.

Q2: Can you cut galvalume sheets in small batches with zero minimum order quantity in Shanghai?

Shanghai Biying International Trade supports slit cutting, slitting, and leveling. We supply small samples and trial orders from smaller manufacturers with no minimum order requirement.

Q3: Is Baosteel DX51D+AZ AZ150 in stock?

Baosteel, JISCO, and Ansteel: Full grade and zinc-coating range in year-round stock. DX51D+AZ, DX53D+AZ, G550+AZ available for immediate pickup.

Q4: Can aluminum-zinc coated steel undergo anti-fingerprint treatment?

Offers fingerprint-resistant passivation and oil coating. Ideal for home appliance housings to resist fingerprints and enhance appearance.
