Performance indicators: in general, only structural, tensile and deep-drawn galvanized sheet with tensile performance requirements.
(1) Tensile test:
(1) Performance indicators: in general, only structural, tensile and deep-drawn galvanized sheet with tensile performance requirements. Structural galvanized sheet requirements with yield point, tensile strength and elongation, etc.; tensile only requires elongation. Specific values in this section "8" in the relevant product standards.
② test method: the same test method with the general thin steel plate, see "8" provided by the relevant standards and "ordinary carbon steel sheet" listed in the test method standard.
(2) Bending test:
Bending test is to measure the performance of sheet metal process of the main project, but the national standards of various galvanized sheet requirements are not consistent, in addition to the U.S. standard structural grade, the rest do not require bending and tensile test. Japan, in addition to structural grade, building corrugated sheet and general corrugated sheet other than the rest are required to make the bending test.
Requirements: general requirements for galvanized sheet bending 180, the outer surface of the zinc layer shall not be detached, the plate base shall not have cracking and fracture.
