Electrogalvanized Steel

Cascadia Metals offers Electrogalvanized Steel in a variety of sizes. Electrogalvanized (electroplated) Steel is cold-rolled carbon steel with a metallic coating composed of 99.99% zinc which is uniformly applied throughout the coil by electro-deposition. The steel sheet is fed through a series of washes and rinses then into a zinc plating bath. The coating develops as positively charged zinc ions in the solution are electrically reduced to zinc metal and deposited on the positively charged sheet steel. The result is a smooth, tight-knit zinc coating on the steel that is highly ductile. The zinc coating protects the base metal by providing a barrier to corrosive elements and also by the sacrificial nature of the coating.

Compared to galvanized steel, Electrogalvanized Steel offers similar performance with lower coating thickness and a brighter, more aesthetically appealing surface. Electrogalvanized Steel offers superior surface quality, excellent corrosion resistance, and outstanding formability and paintability.

Benefits

Formability – well suited for simple bends to deep drawing applications

Appearance – no visible spangle means more uniform surface appearance

Paintability – readily paintable, commonly used for surface critical painted applications

Cost Savings – the initial cost is typically less compared to other hot-dipped steels

Our Electrogalvanized Steel meets ASTM A879 requirements.

So you can rest assured our product will meet all standard specifications per ASTM.

Options

Chemical Treatment

A chemical surface treatment is available which consists of a thin, invisible, corrosion inhibiting, inorganic, chemical film applied on both sides of the metallic coated surface. This film is applied at the metallic coating line by dipping the steel strip into a solution of corrosion inhibiting chemicals. The chemically treated surface is much more resistant to rust which can occur in humid conditions during storage or transportation.

RoHS Compliance

Due to the types of products manufactured using Electrogalvanized Steel, RoHS compliant surface treatments are many times required. RoHS (Restriction of Hazardous Substances) is a European Union regulation that bans the use of certain substances, over specified concentrations, in electronic equipment. All Electrogalvanized Steel products supplied by Cascadia Metals will be RoHS compliant.

End-Use Applications

Typical uses for Electrogalvanized Steel include agricultural equipment, appliance parts, architectural equipment, automotive parts, electrical  equipment, trailers, fencing, ceiling grids and door applications as well as hardware and smaller components.
