We provide a wide lineup of sheet thicknesses from 50 μm to 1.2 mm with functionality such as beautiful surface finishes, scratch-resistance, workability, paintability, solderability and conductivity.
Surface-treated steel sheet is used for many different purposes. Of the various types electrogalvanized steel sheet has the highest market share. Galvanized steel sheet can be divided into hot-dip galvanized steel sheet and electrogalvanized steel sheet (JIS G3313 EG). Toyo Kohan's "Silver Top" has been the leader in the electrogalvanized steel sheet field. As Silver Top has many superior properties that are not available in other products, ever since production started in 1967 it has been used for a wide range of uses and has an excellent reputation.
For example, it is available in a beautiful golden color that changes the image of ordinary galvanized steel sheet, so that it is used for various design purposes such as different types of cases, covers and panels. In addition, our advanced rolling technology makes it possible for us to produce ultra-thin 50 μm sheets (SF) which is unprecedented in galvanized steel sheets. This is helping our customers to reduce costs by replacing copper foil, albata and phosphor bronze foil. Scratch-resistant steel sheet makes stamping of small parts possible and we have helped customers improve their yields by supplying steel sheet with mechanical properties suitable for machining. Due to these factors, Silver Top has been used in many different fields for years.
The increased price of nickel in recent years has led to the increase in the price of stainless steel. Therefore, we have developed "High-strength Silver Top" to replace stainless steel. High-strength Silver Top is much stronger than regular cold-rolled steel sheet, has added elasticity, can be drawn and has various types of galvanizing. It is being used as a new material in electrical and electronic components to reduce costs.
