1. general cold-rolled sheet SPCCSPCC refers to the continuous cold rolling of steel castings into thin steel coils or metal sheets according to the cold rolling mill. The SPCC surface has not been maintained. When exposed to gases, particularly under humid and cold conditions, it oxidizes very readily. It accelerated the rate of atmospheric oxidation, resulting in the formation of dark red rust. Throughout the entire application process, the surface shall be coated with paint, electroplated, or otherwise protected.

2. definition: the basic material of the electric welding steel plate SECCSECC of the sheet metal processing company with hot dip coating or electro-galvanized layer is the general hot rolled steel coil, which passes through deoiling, pickling passivation, electroplating process and various post-treatment processes. After undergoing the entire production process, the continuous electro-galvanizing production line yields electro-galvanized products. Suzhou automobile chassis production and processing is the core technology that sheet metal technology staff must master, and laser cutting is also the main process of producing sheet metal equipment. It not only contains the traditional laser cutting and blanking, stamping processing, bending and forming methods and process parameters, but also contains the structural characteristics and process parameters of various cold stamping dies, the basic principles and operation steps of various facilities, and its new stamping technology and new technology. SECC not only has the physical properties and processability of general hot-rolled steel plates, but also has excellent corrosion resistance and ornamental decoration appearance. In the markets for electronic devices, electrical appliances, and home goods, it boasts strong competitiveness and high substitutability. For example, SECC is commonly used in computer case enclosures.

3. definition of hot dip: SGCC hot dip hot dip galvanized steel coil with hot dip or electrogalvanized layer on the surface refers to the processing of semi-finished products after hot pickling passivation or hot rolling cleaning and quenching.
