SECC is a stamping material, which is coated with a zinc layer on the surface of the cold-rolled sheet. Rust and corrosion-resistant
SECC electrogalvanized plates and strips are featured with good erosion-resistant, high surface quality(O5 plate surface are available) and excellent processing and coating performances. They can be used to manufacture inside an outside automotive plates , structural parts and reinforcements
The electro galvanization process is an industrial process which is used to coat base steel with the layer of zing by electroplating. The zinc coating obtained through this process protects the base steel from rust and corrosion. Moreover, the zinc coating achieved through electroplating process is highly accurate and precise if the coating thickness is considered. There are two types of electrolytes that are used for electro galvanization i.e. alkaline and acidic electrolytes.
Nominal thickness: 0.30mm~2.0mm, nominal width: 800mm~1830mm
(Note: nominal thickness of a plate/strip is sum of base plate thickness and coating thickness.)
When a material grade is specified as electro-galvanized steel, it simply refers it has been subjected to an electro galvanization process by which galvanization is performed. Through this process, a coating of zinc is applied on the surface of the steel. Zinc protects the steel from rusting and other issues. Zinc coating increases the life of base steel. Since the coating is done through electrolysis, therefore, it is said as electro-galvanized steel
- The mechanical and process performances of pure zinc coated plates/strips must comply with the stipulations of those of relevant base plates. The base plate grade is SPCC、SPCD、SPCE, and the corresponding base plate standards is Q/BQB 402-2003.
- Among the mechanical performances of Zn-Ni alloy coated plates/strips, breakage percent elongation is allowed to be lowered by 2 units against that of relevant base plates, r is allowed to be lowered by 0.2 against that of relevant base plates and other mechanical and process performances shall comply with the stipulations of those of relevant base plates
