Technical Specifications of Electro Galvanized Steel Coil

Electro Galvanized Steel Coil Manufacturer - ISO-Certified OEM/ODM Supplier

Electro galvanized steel coil manufacturer operations deliver precision-coated steel products through advanced electroplating technology, serving automotive, construction, and appliance industries worldwide. As a specialized producer, we provide zinc-coated steel coils with coating weights ranging from 20-120 g/m² per side, meeting ASTM A879/A879M and EN 10152 specifications. Our manufacturing facility processes cold-rolled steel substrates with thickness tolerances of ±0.02mm, ensuring consistent surface quality for stamping, roll-forming, and deep-drawing applications across diverse industrial sectors.

What is Electro Galvanized Steel Coil?

Electro galvanized steel coil represents cold-rolled steel substrate electroplated with zinc coating through electrochemical deposition process, producing uniform metallic layer with thickness precision of ±2 micrometers. This manufacturing method deposits pure zinc onto steel surface at controlled current density of 20-60 A/dm², creating corrosion-resistant barrier with superior paint adhesion compared to hot-dip galvanizing alternatives.

Electro Galvanized Steel Coil Technical Specifications

Our electro galvanized steel coil production adheres to ASTM A879/A879M-17 Grade A requirements, featuring zinc coating mass of 50-120 g/m² (Z50-Z120 designation), base metal thickness range of 0.15-3.0mm, and coil width capabilities up to 1,850mm. Material exhibits minimum yield strength of 140-550 MPa depending on substrate grade, with surface roughness maintained below Ra 1.2μm for optimal coating uniformity. Chromate passivation treatment per ASTM B201 provides additional corrosion resistance, achieving 96-hour neutral salt spray test performance according to ASTM B117 standards.

Why Choose Our Electro Galvanized Steel Coil Manufacturing

Our ISO 9001:2015 certified production facility operates six electroplating lines with annual capacity of 800,000 metric tons, maintaining zinc coating uniformity within ±5% across coil width. We utilize inline thickness gauges with 0.1-micron resolution and automated surface inspection systems detecting defects as small as 0.3mm diameter. Mill-direct pricing structure eliminates intermediary markups while maintaining IATF 16949 automotive quality standards, supported by full material traceability and third-party test certification for every production lot.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Standard MOQ stands at 25 metric tons per specification for stock dimensions, with flexibility for 10-ton trial orders on commonly produced grades. Custom width or coating weight specifications require 50-ton minimum to justify slitting line setup and electroplating parameter adjustments.

Do you provide material test certificates?

We supply EN 10204 Type 3.1 mill test certificates with every shipment, documenting chemical composition per ASTM E415 optical emission spectrometry, mechanical properties per ASTM E8 tensile testing, and coating weight verification through ASTM A90 triple-spot test methodology. Additional third-party certification available upon request.

What is the typical delivery time?

Stock specifications ship within 7-10 working days ex-works, while custom orders require 25-30 days including substrate procurement, electroplating processing, and quality inspection protocols. Express production available for urgent requirements with 15-day lead time at premium pricing.

Can you cut to custom sizes?

Our precision slitting capabilities accommodate widths from 20mm to 1,850mm with tolerance of ±0.5mm, while cut-to-length processing handles sheets from 500mm to 6,000mm length. Blanking services available for complex shapes using CNC cutting equipment maintaining dimensional accuracy within ±0.3mm across all edges.
