SECIF steel plate 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.
SECIF steel 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.)
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.)
SECIF steel 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 DC05(BSC2), and the corresponding base plate standards is Q/BQB 403-2003.
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.

SECIF steel coating bending test:
1. Steel plates and strips for drawing purpose are subject to coating bending test. No coating strips on the outside surface of a sample( at the spot over 7mm away from two edges of the sample), which is bended by 180 degrees in any direction with bending center diameter of 0a, when its two surfaces are met.
2. Steel plates and strips for cold forming purposes are subject to coating bending test. There are no coating strips on the outside surface of a sample( at the spot over 7mm away from two edges of the sample), which is bended by 180 degrees in any direction. Refer to provisions of relevant base plates for bending center diameter and take 0a as the bending center diameter in case of no requirements by the base plates for it.
