We apply various plating to the very thin and wide roll steel foil to add functions according to the use. Steel foil can be used as a core material or a reinforcing material, and as a face material we can magnetize it. We have a full lineup of steel foil with various functions from a thickness of 25 μm.
In recent years there has been a growing demand for "smaller", "thinner" and "lighter" materials in various fields and for various uses because of environmental and energy concerns.
Toyo Kohan has collected its core technologies of rolling, surface treatment and lamination to produce and sell steel foil.
Steel foil is available in thicknesses of 25 μm to 100 μm (thicknesses over 100 μm can be produced as normal material) and widths up to 1,000 mm.
In addition, depending on a customer's uses (the properties required), we can treat the steel foil with galvanizing and electrolytic chromic acid.
* The sheet thickness and product width that we can provide depends on the steel type (hardness) and plating type, so please be sure to refer to the separate Available Sizes page.
Although there are many ways to use steel foil, reducing the gauge from general steel materials or using steel foil as an alternative to other metal foils can help to reduce costs.
Combining steel foil with other materials (resins, paper, etc.) can improve the rigidity and strength of core materials and reinforcing materials. In addition, it is also possible to add "magnetic" properties. As a result, steel foil is used in a wide variety of ways.
