65Tons AZ120 Aluzinc Steel Sheet to Indonesia

We signed a new export order on September 1, 2026. An Indonesian customer placed 65 tons of AZ120 aluzinc steel sheet with us, covering three cut-to-length sizes built around a 1219 mm (4 ft) width. This post lays out the buyer’s market, the exact order specifications, why the customer chose Wanzhi, and the related products we keep in stock for Southeast Asia.

1. Customer Country Background: Why Indonesia Keeps Buying Coated Steel

Indonesia is the largest economy in Southeast Asia, and steel demand there is still climbing. A few numbers explain why a distributor in Jakarta, Surabaya, or Batam would spec aluzinc sheet right now:

  • Construction drives the market. In 2025, the building sector accounted for about 78% of Indonesia’s domestic steel consumption. Roads, factories, warehouses, and the new Nusantara capital project keep pulling in structural and cladding material.
  • Imports fill the gap. Imported steel made up roughly 55% of finished steel consumption in 2025, and China supplied about 46% of those imports. Coated steel (galvanized and aluzinc) sits among the top three imported product categories, right behind billet and hot-rolled coil.
  • 2026 is still growth. SMM’s 2026 outlook puts Indonesian crude steel demand up about 4% to 20.1 million tons, with all three metrics (production, exports, imports) positive for the year.
  • The climate demands the right coating. Indonesia’s tropical marine environment brings high humidity, heavy rainfall, strong UV, and widespread coastal salt spray. Plain galvanized steel wears faster here. Aluzinc (55% Al, 43.4% Zn, 1.6% Si) resists corrosion roughly 2 to 4 times longer than an equal-thickness GI sheet and holds up better under UV, which is exactly why AZ120 is a common spec for roofs and wall panels in the region.
  • Compliance matters. Indonesia runs a mandatory SNI certification scheme and has applied anti-dumping duties on imported galvalume of up to 37%. Buyers need a supplier who can produce test reports and documentation that clear customs, not just a low quote.

That combination (a growing construction market, heavy import reliance, a corrosive climate, and strict certification) is why aluzinc sheet keeps showing up in Indonesian bills of materials.

2. Order Details

The order was signed on September 1, 2026. Total quantity is 65 tons, all in AZ120 aluzinc steel sheet, delivered cut-to-length rather than as coil.

The number of wafers can be calculated using the density formula from the three specification parameter tables (≈642/768/536 wafers).

* Sheet counts use the standard formula Weight = thickness x width x length x 7.85 (density in kg per mm/m/m) and round to whole sheets.

Why these numbers

1219 mm width. That is exactly 4 feet, the legacy imperial coil width that became a global default because so much downstream equipment was built around it. Most Indonesian roll-forming lines, panel presses, and fabrication shops are set up for 1219 mm, so the buyer avoids on-site slitting.

1.5 mm and 2.0 mm thickness. These are mid-gauge structural sheets. At 1.5 mm they suit wall panels, ducting, and appliance or electrical enclosures. At 2.0 mm they handle heavier roofing profiles, structural cladding, and load-bearing components. Both thicknesses sit inside Wanzhi’s standard GL sheet range (0.15 to 6.0 mm).

Cut-to-length 1630 / 1700 / 2438 mm. These are panel and module dimensions, not random cuts. 2438 mm is 8 feet, a common structural and cladding module. Receiving steel already cut to size saves the buyer labor and scrap at the fabrication shop.

AZ120 coating. AZ120 means a total double-side aluminum-zinc coating weight of 120 g/m². It is the mid-high tier of the AZ scale (AZ30 to AZ150), rated for high-humidity and coastal environments with a salt-spray life of 2000 to 2500 hours before red rust. For an Indonesian buyer, that is the difference between a roof that needs replacing in a decade and one that runs past twenty years.

Standards and substrate. Aluzinc sheet in this range is supplied to JIS G3321, in grade DX51D+AZ (commercial). Exact grade and zinc-coating certificate follow the mill test report for this specific batch.

3. Why Choose Wanzhi

This is the part that matters for repeat business. A single 65-ton order is easy to quote; consistent delivery is harder. Here is what we bring to an Indonesian buyer:

  • Full aluzinc range. We supply GL coil, GL sheet, PPGL (prepainted aluzinc) coil, corrugated aluzinc sheet, and slit strip, with coating from AZ30 to AZ150. One supplier covers the whole product line instead of three.
  • Certified and inspected. Our system runs on ISO 9001, with SGS, BV, and CE backing. Every batch ships with a mill test certificate, and we arrange customer-commissioned third-party inspection when required.
  • In-house processing. We cut to length, slit, corrugate, and profile in our own workshop. That is how we hit an exact size like 1.5 x 1219 x 1630 mm without sending the buyer to a second vendor.
  • Indonesia track record. We have already shipped aluzinc and PPGL volumes to Indonesia, including a 120-ton red PPGL coil order to Batam. The export paperwork, Incoterms, and SNI-aware documentation are routine for us.
  • Climate-matched specs. Our sales team recommends coating and substrate based on where the steel will sit (coastal, industrial, inland), so the buyer does not overpay for AZ150 where AZ120 is enough, or under-spec and lose years of service life.
  • Responsive. Quotes, inspection reports, and production updates turn around fast, which matters when a distributor is lining up fabrication slots.

FAQ

Q1: What is the difference between aluzinc, galvalume, and GL steel?

They are the same product family. Aluzinc and galvalume both describe the 55% aluminum, 43.4% zinc, 1.6% silicon coating; GL is the common abbreviation for galvalume steel. The bare sheet has a silver-white spangled finish.

Q2: Is AZ120 enough for coastal Indonesia?

For most coastal and high-humidity sites, yes. AZ120 is rated for high-humidity and coastal environments with a 2000 to 2500 hour salt-spray life. Sites within a few kilometers of the open sea or in heavy industrial zones may prefer AZ150.

Q3: Can Wanzhi supply exact cut-to-length sizes like 1.5 x 1219 x 1630 mm?

Yes. We cut to length, slit, and profile in-house. Widths up to 1250 mm and lengths up to 6000 mm are standard; tell us the dimensions and we quote against them.

Q4: Which standard applies to AZ120 aluzinc sheet?

Common standards are EN 10346 (Europe), ASTM A792 (US), and JIS G3321 (Japan). We supply to all three and issue the matching mill test certificate.

Conclusion

The September 1 order is a straightforward one on paper: 65 tons of AZ120 aluzinc steel sheet, three cut-to-length sizes, one Indonesian buyer. What makes it worth announcing is the pattern behind it. Indonesia’s construction market is still growing, imports cover more than half of finished steel demand, and the climate pushes buyers toward longer-life coatings like aluzinc. A 65-ton, three-size order is exactly the kind of mixed specification that tells us the buyer is servicing real downstream projects, not just stocking one SKU.

If you are sourcing aluzinc sheet for Indonesia or the wider region, the product pages above are the fastest place to start. Reach out with your sizes and coating requirement and we will quote against the actual mill test report.
