SECD

SECD 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.

SECD electrogalvanized automotive plates sizes:
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.)

SECD electrogalvanized automotive plates mechanical and process performances:

  1. 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.
  2. 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.
