Aluminum-Coated Steel Coil Price Guide: What Buyers Need to Know
Aluminum-coated steel coil — commonly known as aluzinc, galvalume, or 55% Al-Zn coil — is widely used in roofing, wall cladding, appliances, automotive parts, and construction. Its price is directly influenced by raw material costs (aluminum ingot, zinc ingot, steel base), specifications, surface treatment, and market supply-demand dynamics, which means prices can fluctuate significantly.
In this guide, we break down the key pricing factors and share practical advice for buyers sourcing aluminum-coated steel from China.
Current Price Range (September 2026)
Based on recent FOB China market data:
| Product Type | Price Range (USD/MT) | Notes |
|---|---|---|
| Aluzinc / Galvalume (55% Al-Zn) | $660 – $900 | Standard 0.5mm AZ150, mill finish |
| — Thinner gauge (0.25–0.35mm) | $780 – $980 | Higher processing cost |
| — Anti-fingerprint (AFP) | +$20 – $40 | Premium over base price |
| — Prepainted / Color-coated | +$120 – $250 | Depending on paint system |
| Pure aluminum coil (1xxx / 3xxx series) | $2,050 – $2,750 | Entirely different product category |
Note: These are reference ranges based on September 2026 market conditions. Actual prices vary daily. Always request a current quotation with your exact specifications.
Core Factors That Affect Pricing
1. Thickness & Width (规格尺寸)
Thickness and width are the biggest single price drivers for coated steel coil:
- Standard gauges (0.5–1.2mm) — Most economical, highest production volume
- Thin gauges (0.25–0.4mm) — 15–30% premium due to more rolling passes and lower yield
- Thick gauges (1.5–3.0mm) — Modest premium of 5–15%
- Non-standard widths — Custom widths outside common ranges (1000mm, 1200mm, 1250mm, 1500mm) add a surcharge
Rule of thumb: The thinner and more customized the dimensions, the higher the per-ton price.
2. Steel Mill & Quality Grade (材质与品牌)
Different steel mills command different price levels:
| Mill Tier | Examples | Price Premium | Best For |
|---|---|---|---|
| Top tier (state-owned) | Baosteel, WISCO, Ansteel, Meishan (Meigang) | +10–20% | Critical applications, strict quality requirements |
| Mid tier (large private) | Yieh Phui, Jingye, ZS Steel, Huaqiang | Base price | Most commercial applications |
| Economy tier (regional mills) | Various local mills | -5–10% | Non-critical use, budget projects |
The coating composition also matters: 55% Al-Zn (aluzinc/galvalume) is the most common, while pure aluminized (Type 1 / Type 2) is a different product with its own pricing structure.
3. Surface Treatment (表面处理)
Surface finishes and treatments add incremental cost:
| Treatment | Typical Cost Premium | Common Applications |
|---|---|---|
| Chromate passivation | Standard (included) | General purpose |
| Oiled surface | +$10–25 / MT | Storage protection |
| Anti-fingerprint (AFP) | +$20–40 / MT | Appliances, visible surfaces |
| Protective film lamination | +$15–30 / MT | Fabrication, polished surfaces |
| Pre-painted / color-coated (PPGL) | +$120–250 / MT | Roofing, cladding, facades |
4. Coating Weight (镀层重量)
The thickness of the aluminum-zinc coating affects both price and corrosion resistance:
- AZ50 (50g/m²) — Lightest, lowest cost
- AZ100 (100g/m²) — Common for interior use
- AZ150 (150g/m²) — Standard for most exterior applications
- AZ200+ (200g/m²+) — Premium, highest corrosion resistance
Each step up in coating weight adds roughly 3–8% to the base coil price.
5. Regional & Freight Factors (区域与运费)
Prices vary by production region in China:
- East China (Shanghai, Jiangsu, Zhejiang) — Most suppliers, competitive pricing, good for FOB Shanghai
- North China (Hebei, Shandong) — Lower base prices, more small mills
- South China (Guangdong) — Slightly higher prices, faster delivery to local customers
- Inland regions — Additional inland freight cost to coastal ports
For export orders, FOB terms from Shanghai or Ningbo are most common and simplify freight comparison.
Recent Market Context
Aluminum-coated steel prices have been somewhat volatile in 2026, driven mainly by:
- Aluminum ingot prices on the Shanghai Futures Exchange (SHFE), which have seen 8–12% swings quarter to quarter
- Zinc prices, which have been more range-bound but still influence aluzinc pricing
- Downstream demand from construction and home appliance sectors, which has been mixed
- Energy costs affecting steel mill production economics
In the South China market, standard AZ150 galvalume coil (0.5mm x 1200mm) has been trading around $720–760/MT FOB, while high-end Baosteel material or special thin-gauge specifications can reach $850/MT and above.
Pure Aluminum Coil vs. Aluminum-Coated Steel
Make sure you’re comparing the right products:
| Aluzinc / Galvalume | Pure Aluminum Coil | |
|---|---|---|
| Structure | Steel core + Al-Zn coating | Solid aluminum alloy |
| Price range | $660–$900 / MT | $2,050–$2,750 / MT |
| Primary use | Roofing, cladding, panels, appliances | Curtain walls, gutters, heat exchangers |
| Weight | Heavier (steel base) | Lightweight |
| Price driver | Steel + Al + Zn raw materials | Aluminum ingot (LME / SHFE) |
They are completely different product categories with entirely separate pricing dynamics.
Practical Procurement Tips
1. Get Multiple Quotes with Exact Specs
Always request quotes from at least 2–3 suppliers with identical specifications to make valid comparisons. Provide:
- Exact thickness and width
- Coating type and weight (e.g., AZ150 galvalume)
- Surface treatment (passivated, oiled, AFP, prepainted)
- Standard / tolerance requirements (GB, ASTM, JIS)
- Quantity and delivery timeline
2. Monitor Raw Material Futures
Track the SHFE Aluminum and SHFE Zinc futures prices. Raw material costs typically pass through to finished coil prices within 1–3 weeks. If you see a sustained downtrend in aluminum futures, it may be worth waiting a bit before placing a large order.
Conversely, if raw materials are rallying, locking in current pricing sooner rather than later can save money.
3. Clarify the Pricing Formula
Many mills quote using a “base price + processing fee” model. Always confirm:
- Is the quote EXW, FOB, or CIF?
- Are packaging costs included?
- Is the price per metric ton (MT) or per square meter?
- What’s the tolerance on weight / thickness?
- Are inspection and MTC documents included?
- What are the payment terms (T/T, L/C, etc.)?
4. Standardize Where Possible
If your application allows, choosing standard sizes and coatings can significantly reduce cost:
- Standard widths: 1000mm, 1200mm, 1219mm, 1250mm, 1500mm
- Standard thicknesses: 0.4mm, 0.5mm, 0.6mm, 0.8mm, 1.0mm, 1.2mm
- Standard coatings: AZ100, AZ150 with chromate passivation
5. Build Long-Term Supplier Relationships
Working consistently with 1–2 reliable suppliers gives you:
- Better pricing as your volume grows
- Priority allocation during tight supply periods
- More flexible payment terms over time
- Faster response on quotations and technical questions

Frequently Asked Questions
What is the current price of aluminum-coated steel coil?
As of September 2026, aluminum-coated steel coil (55% Al-Zn / galvalume) generally ranges from approximately $660–$900 per metric ton (FOB China), depending on thickness, width, coating weight, surface treatment, and steel mill. Thinner gauges and special treatments are at the higher end, while standard thicker gauges are at the lower end. Prices move with aluminum and zinc raw material costs, so check current market conditions before purchasing.
What's the difference between aluzinc (galvalume) and pure aluminum coil?
Aluzinc (also called galvalume or 55% Al-Zn) is steel sheet coated with an alloy of 55% aluminum, 43.5% zinc, and 1.5% silicon. It combines the corrosion resistance of aluminum with the galvanic protection of zinc, and is significantly cheaper than pure aluminum. Pure aluminum coil is solid aluminum alloy (no steel core), costs 2–3x more, and is used for different applications such as curtain walls, gutter systems, and heat exchangers. They are entirely different product categories.
How does thickness affect aluminum-coated steel pricing?
Thickness is one of the biggest price factors. Thinner gauges (0.25–0.4mm) cost more per ton because they require more rolling passes and produce less yield from the same base material. Standard thicknesses (0.5–1.2mm) are usually the most economical. Thicker gauges (1.5mm+) are also somewhat higher in per-ton cost due to additional processing. Special or non-standard widths also add a premium.
Which steel mills produce the best aluminum-coated steel?
Top Chinese producers of aluzinc / galvalume coil include Baosteel, Meishan Iron & Steel (Meigang), Yieh Phui, Wuhan Iron & Steel (WISCO), and Ansteel. These state-owned or large mills command a price premium of 8–15% over smaller private mills due to tighter quality control, more consistent coating, and full mill test certificates. For non-critical applications, well-established private mills can offer good value at lower cost.
What surface treatments add cost to aluzinc coil?
Common surface treatments that add cost include: chromate passivation (standard but some premium oils add cost), anti-fingerprint (AFP) coating (+$20–40/ton), oiled finish (+$10–25/ton), color coating / pre-painted (+$120–250/ton depending on paint system and number of coats), and protective film lamination (+$15–30/ton). The exact premium depends on the treatment type, supplier, and order volume.
How can I get the best price on aluminum-coated steel coil?
To get the best pricing: 1) Get quotes from 2–3 suppliers and compare on the same specs, 2) Order in full coil quantities rather than cut-to-length where possible, 3) Monitor Shanghai Futures Exchange aluminum and zinc prices to time your purchases during dips, 4) Clarify whether the quote includes packaging, freight, and taxes, 5) Consider standard sizes and coatings rather than custom specs, and 6) Build a relationship with a reliable supplier for better pricing over time.
How often do aluminum-coated steel prices change?
Aluminum-coated steel prices are closely tied to aluminum and zinc raw material prices, which can change daily on futures markets. However, most steel mills and distributors update their selling prices weekly or bi-weekly. Major price moves tend to happen over weeks or months rather than single days. For long-term contracts, pricing may be formula-based, adjusting periodically with raw material indices.
