What is DX51D AZ Steel Coil?

DX51D AZ steel coil is a continuously hot-dip coated steel product manufactured according to EN 10346:2015 standards, featuring an aluminum-zinc alloy coating (typically 55% aluminum, 43.4% zinc, and 1.6% silicon). The designation "DX51D" indicates its structural quality grade with minimum yield strength of 140-300 MPa, while "AZ" specifies the aluminum-zinc coating composition that delivers three to six times greater corrosion protection compared to conventional galvanized coatings.

DX51D AZ Steel Coil Technical Specifications

Our DX51D AZ steel coil complies with EN 10346:2015 Section 6 requirements, with base metal thickness ranging from 0.25mm to 3.0mm and coating mass between AZ100 (100 g/m²) to AZ185 (185 g/m²) per surface. The product exhibits tensile strength of 270-500 MPa per EN 10346 Table 3, with elongation values of 22% minimum for thickness ≥0.5mm, ensuring excellent deep-drawing characteristics for complex forming operations.

Perfect for Repeat Production Orders
Our 6th order - 30 tons of DX51D AZ coil (0.4mm, AZ100, 1000mm width) for electrical enclosure manufacturing. Batch-to-batch consistency has been remarkable across 180 tons total volume. Chemical composition stable: carbon 0.018-0.022%, perfect for our welding process. Their inventory of common specifications enabled 11-day delivery on this urgent order. Slitting accuracy maintains ±0.4mm on 250mm strips. Coating adhesion passes our 180° bend test without flaking. Price locked for quarterly contracts provides excellent budget predictability.

Acceptable Quality with Initial Documentation Delay
Purchased 20 tons (0.7mm thickness, AZ120 coating) for commercial roofing project. Material quality met EN 10346 requirements, coating uniformity was satisfactory. Initial shipment arrived without EN 10204 3.1 certificates, causing 4-day project delay. Supplier resolved issue promptly, express-couriered documentation and provided partial credit for inconvenience. Material itself performed adequately in roll-forming. Would consider ordering again but emphasize documentation requirements upfront. Surface finish was acceptable 2B grade with minor handling marks on outer wraps.

Reliable Material for Marine Infrastructure
Ordered 16 tons of DX51D AZ coil (0.6mm, AZ150, 1100mm width) for jetty handrail systems. Mechanical properties tested: tensile 478 MPa, yield 172 MPa, elongation 23%. Coating mass averaged 148 g/m² per EN ISO 1460 testing. Material performed well in forming operations with minimal springback. Packaging could be improved - minor moisture ingress on 1 coil during sea freight. Delivered in 31 days to Melbourne. Price point was reasonable for marine-grade specification.

Premium Corrosion Resistance for Desert Climate
Supplied 35 tons (0.5mm thickness, AZ150 coating, varying widths 800-1200mm) for pre-engineered building panels in Abu Dhabi. Coating composition verified at 55.2% aluminum, 43.1% zinc per mill certificates. After 6 months desert exposure with temperature extremes 15-48°C, coating integrity remains perfect. Compared quotes from 5 suppliers, their factory-direct pricing was most competitive. Expedited delivery completed in 29 days. Technical data sheets provided excellent fabrication guidelines for our profile rolling equipment.

Outstanding Technical Support for Material Selection
Procured 22 tons of DX51D AZ steel coil (0.8mm, AZ185 coating) for agricultural equipment manufacturing. Their application engineer recommended AZ185 instead of our initial AZ150 specification, considering our high-humidity storage conditions. Salt spray testing confirmed 720 hours to 5% red rust versus 480 hours for standard galvanized. Cut-to-length service provided 3000mm sheets with burr-free edges. Delivered in 24 days to Santos port. Material traceability documentation was comprehensive.

Good Value DX51D Coils for Industrial Ducting
Ordered 18 tons (0.7mm thickness, AZ120 coating, 1000mm width) for HVAC ducting systems. Material certificates showed yield strength at 165 MPa, within specification range. Coating adhesion passed our bend test requirements. Delivery took 33 days, slightly longer than quoted 28 days due to customs clearance. Price was 8% lower than German suppliers for comparable quality. Minor edge waviness on 2 coils but within EN 10346 tolerance. Would order again for cost-sensitive projects.
