galvanized sheet mechanical properties


1. Tensile test:
Aluminized aluminum zinc sheet index (unit: g / m2)
JISC3302 Code Z12 Z18 Z22 Z25 Z27 Z35 Z43 Z50 Z60
Amount of galvanized 120 180 220 250 270 350 430 500 600
ASTMA525 Code A40 A60 G60 G90 G115 G140 G165 G185 G210
Amount of galvanized 122 183 183 275 351 427 503 564 640

① performance indicators: In general, only the structure with, with the deep drawing with the use of galvanized sheet tensile performance requirements. The structure of the galvanized sheet with a yield point, tensile strength and elongation, etc .; stretch with only the required elongation.
② Test method: the same as the general test method of thin steel plate, see "8" provided by the relevant standards and "ordinary carbon steel sheet" listed in the test method standards.

2. Bending test:
Bending test is a major project to measure the performance of sheet metal, but the national standards for a variety of galvanized sheet requirements are not consistent, the US standard in addition to the structural level, the rest are not required bending and tensile test. While Japan, in addition to structural level, architectural corrugated board and the general corrugated board other than the rest are required for bending test.
Requirements: the general requirements of galvanized sheet bending 180, the outer surface shall not have zinc layer separation, the board must not have cracks and cracks.
