SECC refers to electrolytically galvanized steel sheet. The “CC” suffix in SECC, like the base material SPCC (cold rolled steel sheet) before electroplating, indicates it is a cold-rolled general-purpose material.
It features excellent workability. Additionally, due to the electroplating process, it possesses a beautiful, glossy appearance and excellent paintability, allowing for coating in various colors.
It is the most widely circulated processed steel sheet. Applications of SECC As a general-purpose steel, it does not offer high strength. Furthermore, its zinc coating is thinner than hot-dip galvanized steel, making it unsuitable for harsh environments. It is commonly used in home appliances, indoor electrical equipment, etc.
Advantages
Low cost, readily available
Aesthetically pleasing surface
Excellent workability and formability
Superior paintability
As the most common type of processed steel sheet, it is available at a low cost. Using SPCC with excellent workability as the base material, it features a thin and uniform electroplated coating, making it easy to process through methods like pressing.
SGCC is a steel sheet that has undergone hot-dip galvanization. Since it is SPCC subjected to hot-dip galvanizing, its fundamental properties are nearly identical to SPCC. It is also known as galvanized sheet. Its coating is thicker than SECC, providing superior corrosion resistance. Among SECC counterparts, it also includes alloyed hot-dip galvanized steel sheets and aluminized steel sheets. Applications of SGCC
While not a material of exceptionally high strength, SGCC excels in corrosion resistance, making it suitable for diverse applications. Beyond power transmission tower materials and guide rails, it is used in vehicle running components. Its architectural uses are extensive, including roll-up doors, window guards, and as galvanized sheet for building exteriors and roofs.
Advantages and Disadvantages of SGCC
Advantages
Long-lasting high corrosion resistance
Relatively low cost and readily available
Excellent workability
SGCC, like SECC, is based on SPCC as its parent material, sharing similar properties such as ease of processing.
Standard Dimensions for SECC and SGCC
Pre-galvanized SECC sheet thickness has standard dimensions, but the actual thickness varies with coating weight, so SECC lacks a fixed standard size. The standard dimensions for pre-galvanized SECC sheets match those of SPCC: thicknesses ranging from 0.4 mm to 3.2 mm, with multiple thickness options available.
