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.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ for electrolytic galvanized steel strip is 5 metric tons per specification. For high-volume contracts exceeding 50 tons monthly, we offer flexible scheduling and consignment inventory programs. Mixed-specification orders are accommodated with 10-ton minimum combined weight.

Do you provide material test certificates?

Yes, every shipment includes EN 10204 Type 3.1 mill test certificates signed by both manufacturer and independent inspection agency. Documentation details chemical composition per heat analysis, tensile properties, coating weight verification, and dimensional measurements. Additional third-party testing through SGS or Bureau Veritas can be arranged upon request.

What is the typical delivery time?

Standard lead time for in-stock specifications ranges 7-10 business days from order confirmation to departure from our warehouse. Custom thickness or width requirements necessitate 4-6 weeks for mill production scheduling. Expedited processing is available for urgent requirements, with partial shipments released as production completes.

Can you cut to custom sizes?

Our precision slitting capabilities accommodate width tolerances of ±0.5mm for strips 25mm to 1,220mm wide. Coil ID options include 508mm and 610mm to match your decoiling equipment. Cut-to-length services provide sheets from 500mm to 6,000mm with squareness tolerance within 2mm per meter. Edge conditioning options include deburred, rounded, or square-cut profiles.

Premium Strip for Precision Stamping Operations

Supplied 9 tons of 0.4mm ultra-thin electrolytic galvanized strip for automotive sensor housings. Thickness tolerance held to ±0.02mm across entire 25-ton coil weight. Z100 coating provided 7.2 microns per side verified by our X-ray fluorescence testing. Carbon content at 0.08% delivered exceptional deep-draw characteristics through our 150-ton progressive dies. Custom slit to 380mm width with deburred edges - no tool damage after 50,000 stamping cycles. Technical support provided FEA recommendations for our complex forming geometry.

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.
