Mechanical Properties Of Galvanized Steel Sheet

(1) Tensile test:
① Performance indicators: Generally speaking, only structural, drawing and deep drawing galvanized sheets have tensile performance requirements. The structural galvanized sheet requires yield point, tensile strength and elongation, etc. Only elongation is required for stretching. For specific values, see the relevant product standards in "8" of this section;
(2) Test method: The same as the general sheet steel test method, see the relevant standards provided by "8" and the test method standards listed in "ordinary carbon steel sheet steel".
(2) Bending test:
Bending test is the main project to measure the process performance of sheet metal, but the national standards for various galvanized sheet requirements are not consistent, the United States standard in addition to the structural level, the rest do not require bending and tensile test. In Japan, bending tests are required except for structural grade, building corrugated plate and general corrugated plate.
Requirements: Generally, after the galvanized sheet is bent for 180 years, the outer surface shall not be separated from the zinc layer, and the plate base shall not be cracked and broken.
