SECE is a specific designation for electro-galvanized steel, commonly used in the industry.SECE is a designation used for electro-galvanized steel in accordance with the Japanese Industrial Standard (JIS G 3313). It specifies the requirements for electrolytic zinc-coated cold-rolled steel sheets and coils.SECE electro-galvanized steel products have a thin layer of zinc coating applied through the electroplating process. The zinc coating provides corrosion resistance to the underlying steel substrate.The zinc coating in SECE electro-galvanized steel acts as a sacrificial layer, protecting the steel from rust and other forms of corrosion. It enhances the durability and lifespan of the steel.
SECE electro-galvanized plates and strips are featured with good erosion-resistant, high surface quality(O5 plate surfaces are available), and excellent processing and coating performances. They can be used to manufacture inside and outside automotive plates, structural parts, and reinforcements.

Electro galvanized steel benefits
- Formability – well suited for simple bends to deep drawing applications
- Appearance – no visible spangle means more uniform surface appearance
- Paint ability – readily paintable, commonly used for surface critical painted applications
- Cost Savings – the initial cost is typically less compared to other hot-dipped steels
specific uses and application of SECE electro-galvanised steel
SECE Electro-Galvanised Steel is widely used for interior applications due to its superior performance within unexposed environments. It has a more suitable grey/silver appearance, which makes it a match for applications required to fit a specific presentational criteria. These attributes are very attractive to consumers, which has led to increasing demand for SECE Electro-Galvanised Steel.
Electrolytic versions also have a uniform coating that is ideal for electrical appliances. This coating can even resist the most trivial markings like fingerprints. There is a significantly lower possibility of structure deformation or distortion with this product. Our SECE Electro-Galvanised Steel product range is ideal for manufacturing applications and exhibit excellent formability. Typical applications of SECE Electro-Galvanised Steel include:
- Exposed painted panels
- Non-exposed automotive panels
- Washing machines
- Acoustic ceiling tiles
- Door frames
- Switchboards
- Commercial refrigerators and freezers
