Electro-galvanized Steel Sheet (Silver Top)

Product System

Supporting with a variety of functions beyond common sense for electro-galvanized steel sheets.

Non Coated Silver Top

Characteristics like a beautiful metallic appearance, corrosion resistance, abrasion resistance, paper skidding, fingerprint proof adhesion resistance have been highly regarded for many years among non coated galvanized steel sheets.

Coated Silver Top

A high grade coating finish for superb coating material adhesion and electro-galvanization combined with our company's own thin product compatibility up to 0.11 mm and high processibility of substrates has been well received since it first went to market.

Solderable Silver Top

Lead free solderable steel sheets have a proven track record over more than 10 years. Lead free solder and non active flux are also fully equipped with characteristics demanded for electronic components such as wettability, whisker proofing and high shielding for high surface conductivity.

Black Color Silver Top

Our company's proprietary manufacturing method provides a rapidly improved black color appearance and characteristics common to non coated Silver Top, while the heat radiation characteristics of black color sheets possess ample characteristics required as a substitute material for coated steel sheets.

Composite Laminated Materials

Composite laminated materials using our company's base film laminate technology can be supplied. Ask us about Silver Top as a substrate as well as compatibility with aluminum and other materials.

Steel Foil (SF)

A 50 to 100 µm ultra thin galvanized steel sheet taking advantage of our company's ultra thin rolling technology typified by shadow mask materials. More than 110 µm is acceptable as normal Silver Top.

Silver Top-ECO

In addition to conventional chrome containing type Silver Top, each series can supply eco-friendly chrome free type Silver Top.
