Introduction

For custom galvanized steel sheet metal parts, there are two different materials can be  chosen, one is galvanized steel sheet SECC and the other is hot dip galvanized steel sheet SGCC. They each have different characteristics:

1. Galvanized steel SECC

The substrate of SECC (Steel Electrolytically Chromated Coated) is ordinary cold-rolled steel coil. In a continuous electro-galvanizing production line, this base material undergoes a series of meticulous processes. First, degreasing is carried out to remove any contaminants and oils on the surface. Then, pickling helps to further clean and prepare the steel for electroplating. During electroplating, a thin, even layer of zinc is deposited on the steel. Various post-treatment steps follow to enhance the quality and durability of the coating. As a result, SECC not only retains the mechanical properties and workability of ordinary cold-rolled steel sheets, allowing for easy shaping and fabrication, but also offers superior corrosion resistance and an attractive decorative appearance. This makes it highly competitive and a popular choice in the markets of electronic products, home appliances, and furniture. For instance, the commonly used computer case is often made from SECC, taking advantage of its strength, corrosion resistance, and good looks.

2. Hot dip galvanized steel sheet SGCC

Hot-dip galvanized steel coil, also known as SGCC (Steel Sheet, Zinc Coated by Hot-dip Process), starts as a semi-finished product that has undergone either hot-rolled pickling or cold-rolling. The manufacturing process begins with thorough cleaning to remove surface impurities, followed by annealing to improve the material's internal structure and make it more malleable. Subsequently, the steel sheet is immersed in a molten zinc bath heated to approximately 460 °C. This high-temperature immersion ensures that a thick, adherent zinc layer coats the steel, providing robust corrosion protection. After the zinc coating, the material undergoes quenching and tempering to enhance its hardness and strength, flattening to achieve a smooth surface, and chemical treatment to further optimize its properties. Compared to SECC, SGCC is harder, with reduced ductility that makes deep drawing processes challenging. Its thicker zinc layer offers enhanced corrosion resistance, but this comes at the cost of poorer weldability, limiting its use in applications that require extensive welding.
