DX51D ZAM Steel Coil - Galvanized Aluminum Magnesium Coated Cold Rolled

DX51D ZAM steel coil represents a revolutionary advancement in corrosion-resistant steel technology, featuring a zinc-aluminum-magnesium alloy coating that delivers superior protection compared to conventional galvanized materials. This premium-grade cold-rolled steel coil finds extensive application in construction, automotive manufacturing, and outdoor equipment industries where exceptional durability against corrosive environments is paramount. Engineered to meet stringent European EN 10346 standards, DX51D ZAM steel coil serves critical roles in coastal structures, agricultural buildings, and transportation infrastructure requiring extended service life with minimal maintenance.

What is DX51D ZAM Steel Coil?

DX51D ZAM steel coil is a cold-rolled steel substrate coated with a ternary zinc-aluminum-magnesium (Zn-Al-Mg) alloy layer through continuous hot-dip coating processes. The designation "DX51D" indicates a continuously hot-dip coated steel grade per EN 10346:2015, with the "ZAM" coating typically comprising 6% aluminum, 3% magnesium, and 91% zinc by weight. This innovative coating composition provides exceptional anti-corrosion properties through cathodic protection mechanisms, achieving corrosion resistance 3-10 times superior to traditional galvanized steel in accelerated salt spray testing per ISO 9227.

DX51D ZAM Steel Coil Technical Specifications

Our DX51D ZAM steel coil complies with EN 10346:2015 Section 6 requirements, manufactured with coating mass ranging from Z100 to Z275 (100-275 g/m² total both sides). The base steel exhibits tensile strength of 270-500 MPa with minimum yield strength of 140 MPa, meeting DX51D mechanical properties per EN 10346 Table 3. Standard dimensions include thickness from 0.20mm to 3.00mm, width from 600mm to 1500mm, and coil weight up to 25 metric tons. The ZAM coating demonstrates exceptional adhesability per EN ISO 1519 with minimum bend test performance of 0T (zero times thickness) for materials ≤1.0mm thick.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard minimum order quantity for DX51D ZAM steel coil is 10 metric tons per specification. For custom slitting or specific coating mass requirements, MOQ may be adjusted to 15-20 tons depending on dimensional parameters. We offer flexible ordering for established clients and can accommodate smaller quantities for trial orders with adjusted pricing structures.

Do you provide material test certificates?

Yes, we supply comprehensive mill test certificates (MTC) per EN 10204 Type 3.1 with every shipment, documenting chemical composition, mechanical properties, coating mass, and coating adhesion test results. Additional third-party inspection certificates from SGS, BV, or TÜV are available upon request. All documentation includes heat number traceability and complies with EN 10346:2015 certification requirements.

What is the typical delivery time?

For standard stock specifications (0.40-2.00mm thickness, Z150-Z200 coating), delivery time ranges from 7-12 working days ex-works. Custom coating mass or non-standard dimensions require 15-25 working days production lead time. Express processing is available for urgent orders with 5-7 day delivery for in-stock materials. International shipping transit time varies by destination, typically 20-35 days for sea freight to major ports.

Can you cut to custom sizes?

Our precision slitting lines accommodate custom widths from 20mm to 1500mm with tolerance of ±0.5mm, and our cut-to-length equipment handles sheets from 500mm to 6000mm length with ±2mm accuracy. We provide edge trimming, deburring, and protective film application services. Minimum processing quantity applies based on material specifications - typically 3-5 tons per custom dimension to ensure cost-effective processing.
