Aluminum Zinc Color Coated Steel Sheet - Mill Direct

Aluminum zinc color coated steel sheet stands as one of the most versatile and durable coated steel products available in today's construction and manufacturing markets. Combining the structural integrity of a high-strength steel substrate with a precisely engineered aluminum-zinc alloy coating and a polymer-based color finish, this material delivers outstanding anti-corrosion properties, superior weather resistance, and long-term aesthetic appeal. It finds extensive application in roofing panels, wall cladding systems, home appliances, automotive components, and industrial enclosures. With a base coating typically composed of 55% aluminum, 43.4% zinc, and 1.6% silicon by mass, the alloy layer provides a self-healing barrier that significantly outperforms conventional galvanized coatings. The additional color coating layer — available in polyester (PE), silicon-modified polyester (SMP), or polyvinylidene fluoride (PVDF) finishes — further enhances UV resistance and surface durability, making aluminum zinc color coated steel sheet a preferred choice for architects, engineers, and procurement specialists worldwide seeking mill-direct pricing and reliable supply chains.

What is Aluminum Zinc Color Coated Steel Sheet?

Aluminum zinc color coated steel sheet is a composite flat-rolled steel product manufactured by applying an aluminum-zinc alloy coating (commonly known as Galvalume or AZ coating) onto a cold-rolled steel substrate, followed by a chromate passivation layer, a primer coat, and a topcoat of colored organic polymer. The result is a product that combines metallic corrosion protection with decorative surface functionality, serving critical roles in both structural and aesthetic building applications.

Aluminum Zinc Color Coated Steel Sheet Manufacturing Process

Production begins with cold-rolled steel coils fed through a continuous hot-dip coating line, where the strip is immersed in a molten aluminum-zinc bath at approximately 600°C to achieve AZ coating weights ranging from AZ50 to AZ150 g/m². After cooling and surface treatment, the coated strip passes through a continuous coil coating line where primer and topcoat layers are applied via precision roll coaters and cured in high-temperature ovens at 220–250°C peak metal temperature, ensuring consistent film thickness of 15–25 µm.

Aluminum Zinc Color Coated Steel Sheet Technical Specifications

Standard offerings conform to ASTM A755, EN 10169, and GB/T 12754 specifications. Typical parameters include: base steel yield strength of 250–550 MPa; total coil thickness of 0.30–1.20 mm; coil width of 600–1,250 mm; AZ coating weight of 75–150 g/m² (double-side); topcoat dry film thickness of 15–25 µm (PE) or 25–35 µm (PVDF); pencil hardness of 2H minimum; T-bend flexibility of 0T–2T; and salt spray resistance exceeding 1,000 hours per ASTM B117. Color options span RAL and custom palettes with gloss levels from 10 to 80 GU at 60°.

Initial coil edge quality issue — resolved satisfactorily after follow-up
Ordered 25 MT of 0.70 mm × 1,050 mm AZ120 SMP for a school building cladding project. Upon inspection, approximately 8% of coils showed minor edge wave beyond our flatness tolerance, which risked issues during rollforming. Raised this immediately with the supplier. To their credit, the technical team responded within 12 hours, arranged a third-party inspection, confirmed the non-conformance, and arranged replacement coils shipped within 10 days at no additional cost. Final product met EN 10169 requirements fully. The resolution process was professional. Willing to trial again, but will request pre-shipment flatness inspection going forward.

Competitive pricing for AZ100 PE — solid for our warehouse projects
Sourced 50 MT of 0.45 mm AZ100 PE-coated sheet in RAL 5015 for industrial warehouse cladding across two sites in Dubai. Price per MT was roughly 9% below our previous Gulf supplier for comparable ASTM A755 grade material. Coating adhesion and gloss uniformity (35 GU at 60°) met our project specs. Deducting one star because the color sample provided was slightly lighter than the production batch — within tolerance but noticeable side-by-side. Team acknowledged this and offered an adjusted sample process for future orders. Technical documentation was thorough and customs clearance was smooth.

Good value on AZ150 PVDF — minor lead time variance
Ordered 35 MT of 0.55 mm × 1,200 mm AZ150 PVDF for a coastal Florida roofing application where corrosion resistance is critical. Product quality was solid — salt spray performance and PVDF film thickness at 30 µm checked out against ASTM B117 and ASTM A755 standards. Price was competitive for this spec. Only minor issue: actual shipment departed four days later than the initially quoted schedule, which caused a small delay on-site. Supplier communicated proactively about the delay, which we appreciate. Overall good value; would order again with a slightly padded schedule buffer.

Fourth repeat order — quality and service remain consistent
This is our fourth purchase of 0.35 mm × 914 mm AZ75 PE-coated coils for rollforming into residential roofing profiles. Total volume across all orders now exceeds 200 MT. What keeps us returning is the consistency: coil weight tolerances, coating adhesion, and color matching to our approved RAL 3009 standard have been reliable every time. ASTM A755 test reports accompany each shipment. Customer support resolves any documentation queries within hours. Pricing for repeat clients is fair. Highly recommended for importers needing dependable mill-direct supply to Australia.

Rigorous EN 10169 compliance — ideal for our wall panel production
As a wall panel manufacturer supplying the German market, EN 10169 compliance is non-negotiable. Ordered 60 MT of 0.80 mm SMP-coated AZ120 in RAL 9002. Third-party lab verification of gloss level (42 GU at 60°) and dry film thickness (22 µm) matched mill data sheets precisely. Corrosion resistance performance in our accelerated cyclic tests was strong. The technical consultation prior to order — covering substrate yield strength selection at 350 MPa — was genuinely helpful and saved us from an over-specification. Lead time of 25 days CIF Hamburg was acceptable.

Mill-direct pricing makes a real difference on large contracts
Purchased 80 MT of 0.60 mm AZ150 PVDF in a custom blue shade for a hotel facade project in Texas. Pricing was noticeably competitive — eliminating the distributor layer genuinely showed in the quote. Delivery to Houston port took 28 days, which fit our project timeline. The 24-hour quotation turnaround was accurate; we had a detailed breakdown including coating weight, film thickness specs, and ASTM A755 compliance documentation before close of business. Free sample coils helped our client approve the color before committing. Reordering for Phase 2 shortly.

Consistent AZ100 quality across three consecutive shipments
We've sourced 0.40 mm × 1,000 mm AZ100 PE-coated sheets conforming to GB/T 12754 for our agricultural shed roofing line. Mechanical properties — yield strength averaging 310 MPa — match the mill certificates exactly. T-bend flexibility tested at 1T with zero cracking. This is our third order totalling approximately 120 MT over six months; quality variance between coils has been negligible. Pencil hardness consistently 2H or better. Response to our technical queries regarding primer adhesion was detailed and professional.

Excellent PVDF finish — exceeded our EN 10169 expectations
Ordered 45 MT of 0.50 mm AZ150 with PVDF topcoat in RAL 7016 for a commercial cladding project in Manchester. Salt spray results internally confirmed exceeded 1,200 hours, well beyond the 1,000-hour ASTM B117 threshold stated. Film thickness measured consistently at 28–31 µm across the full coil width of 1,250 mm. Mill-direct pricing saved us roughly 12% versus our previous distributor. Lead time was 22 days to UK port — right on schedule. Technical team answered coating adhesion queries promptly. Will specify this supplier on our next tender.
