Electro Galvanized Steel Strip Coil - Cold Rolled, ASTM A653, Zinc Coating 60g/m²

Technical Specifications of Electro Galvanized Steel Strip Coil

Electro Galvanized Steel Strip Coil - Cold Rolled, ASTM A653, Zinc Coating 60g/m²

Electro galvanized steel strip coil represents a cost-effective solution for applications requiring moderate corrosion protection and superior surface finish. This cold-rolled product undergoes an electroplating process that deposits a uniform zinc layer, typically 60g/m² per ASTM A653 specifications, making it the preferred choice for automotive components, appliance manufacturing, and light construction applications where aesthetic appeal and formability are critical requirements.

What is Electro Galvanized Steel Strip Coil?

Electro galvanized steel strip coil is cold-rolled steel substrate coated with zinc through an electrochemical deposition process, resulting in a smooth, bright surface finish with controlled coating thickness ranging from 40-120g/m². Unlike hot-dip galvanizing, this method provides exceptional surface uniformity and superior paint adhesion characteristics for downstream fabrication processes.

Electro Galvanized Steel Strip Coil Technical Specifications

Our electro galvanized steel strip coil complies with ASTM A653/A653M-20 Section 8 for coating designation ZE50/50 to ZE75/75, featuring substrate grades from commercial quality to high-strength low-alloy (HSLA) with yield strength ranging 140-550 MPa. The zinc coating weight meets Class A requirements with minimum 40g/m² total both sides, while maintaining surface roughness Ra ≤1.5μm for optimal forming performance.

Key Advantages of Electro Galvanized Steel Strip

This material finds extensive application in precision manufacturing due to its exceptional surface quality and dimensional accuracy. The electroplating process delivers superior coating uniformity compared to hot-dip methods, with coating thickness variation maintained within ±10% across the entire coil width. The bright, spangle-free finish eliminates secondary surface preparation requirements, reducing total processing costs by 15-20% for painted applications.

Manufacturing Process & Quality Control

Our production facility employs continuous electrolytic galvanizing lines with inline thickness monitoring systems ensuring coating weight accuracy of ±5g/m². The process includes alkaline cleaning, acid pickling per ASTM B183, electroplating in zinc sulfate solution at current density 30-50 A/dm², followed by chromate passivation treatment conforming to RoHS directives for enhanced corrosion resistance and paint adhesion.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ is 25 metric tons per specification, with coil weights typically ranging 3-8 tons to optimize logistics efficiency. For trial orders or specialized gauges, we accommodate reduced quantities of 10 tons with adjusted pricing, subject to production scheduling availability and material grade requirements.

Do you provide material test certificates?

Yes, we supply EN 10204 Type 3.1 mill test certificates documenting chemical composition per ASTM E1086, mechanical properties per ASTM A370, and coating weight verification per ASTM A90. Additional testing including adhesion per ASTM D3359 and corrosion resistance per ASTM B117 is available upon request with 5-7 business days lead time.

What is the typical delivery time?

Standard specifications maintain 15-20 days delivery from order confirmation, including production scheduling, quality inspection, and export documentation preparation. Custom width slitting or special coating weights require additional 7-10 days processing time. Express production slots are available for urgent requirements with 10-12 days turnaround at premium rates.

Can you cut to custom sizes?

Our precision slitting capabilities accommodate widths from 20mm to 1,250mm with tolerance ±0.5mm, while maintaining edge quality per ASTM A1058 Class 1 requirements. We also provide cut-to-length services for sheets ranging 500-6,000mm with squareness tolerance ±2mm/m, packaged according to customer specifications for direct production line integration.
