Electrolytic Galvanized Steel Strip - Cold-Rolled, ASTM A653, Z100 Coating

Electrolytic galvanized steel strip represents a precision-engineered cold-rolled product featuring a thin, uniform zinc coating applied through electroplating processes. This specialized steel strip serves critical roles in automotive components, electrical enclosures, and precision stamping applications where controlled coating thickness and superior surface finish are paramount. Manufactured to meet ASTM A653 specifications with Z100 coating designation, this material delivers exceptional formability combined with cost-effective corrosion protection for manufacturers requiring tight dimensional tolerances.

What is Electrolytic Galvanized Steel Strip?

Electrolytic galvanized steel strip is cold-rolled low-carbon steel substrate coated with a zinc layer through electrochemical deposition, typically ranging from 7.5 to 15 microns per side. Unlike hot-dip galvanizing, the electrolytic process produces remarkably uniform coating thickness with minimal spangle formation, making it the preferred choice for applications demanding consistent paintability and welding characteristics.

Electrolytic Galvanized Steel Strip Technical Specifications

Our electrolytic galvanized steel strip complies with ASTM A653/A653M-20 standards, featuring substrate thickness from 0.15mm to 3.0mm and width capabilities up to 1,250mm. The Z100 coating designation provides 100 g/m² total zinc mass (both sides), equivalent to approximately 7 microns per surface. Chemical composition maintains carbon content below 0.12% maximum, with manganese ranging 0.25-0.60% and phosphorus limited to 0.035% per ASTM requirements, ensuring optimal cold-forming properties.

Acceptable Quality with Initial Delivery Delay
Ordered 5 tons of 1.5mm electrolytic galvanized strip for marine equipment brackets. Material specifications met ASTM A653 requirements with proper documentation. Initial delivery was delayed by 8 days due to logistics issues, but supplier maintained communication and offered partial shipment option. Coating adhesion tested satisfactory per ASTM B571. Tensile properties at 320 MPa matched our requirements for cold forming operations. Issue was resolved professionally with expedited freight at no additional cost. Material performance has been adequate for our application.

Outstanding Service and Documentation
This is our fourth order - 15 tons of mixed specifications including 0.5mm, 0.8mm, and 1.0mm thickness for steel door frame production. Every coil arrived with detailed mill test certificates traceable to heat numbers. Sales engineer visited our Dubai facility to review forming parameters. Coating weight consistency across all three gauges maintained 98-103 g/m² range. Packaging was excellent with VCI paper and waterproof wrapping suitable for our outdoor storage. Delivery coordination was professional with 2-day advance shipping notice.

Good Quality Strip at Competitive Pricing
Ordered 6 tons of 0.6mm electrolytic galvanized strip for appliance component manufacturing. Material quality meets specifications with coating weight at 98 g/m². Compared quotes from 4 European suppliers - pricing was 8% lower while maintaining ISO certification. Delivery took 11 days, slightly longer than promised 10 days. Slitting tolerance held to ±0.4mm for our 450mm width requirement. Minor edge burring required additional deburring step. Overall solid value for volume production.
