Product Specification: 0.14-1.8mm x 900-1250mm

Two 1450mm hot-dip galvanizing (aluminium) production lines have the functions of annealing reduction, galvanizing, finishing, stretching and straightening, passivation, and can produce 900-1250mm steel bandwidth. 1 # galvanizing line is specially designed for galvanizing with thickness of 0.14-1.8 mm and single-sided galvanizing layer thickness of 20-140 g/. 2 # Aluminum-zinc plating line can be plated with 5%, 15%, 25% and 55% Aluminum-zinc, and the thickness of Aluminum-zinc coating can be 17-35 g/. The annual output of the two lines is 500,000 tons.

The product has excellent shape, surface quality and meets the mechanical performance requirements of users. Widely used in household appliances, construction, automobile and other fields.

Mechanical properties

(1) Tensile test:

(1) Performance indicators: Generally speaking, only galvanized sheets for structural, tensile and deep drawing applications have tensile performance requirements. Among them, galvanized sheet for structure requires yield point, tensile strength and elongation, while for stretching, only elongation is required. Specific values can be found in the relevant product standards in "8" of this section.

(2) Test method: The test method is the same as that of common thin steel plate. See the relevant standard provided by "8" and the test method standard listed in "common carbon steel sheet".

(2) Bending test:

Bending test is the main item to measure the technological performance of sheet metal, but the requirements of various national standards for galvanized sheet metal are not the same. Except for the structural level, the other American standards do not require bending and tensile tests. In Japan, bending tests are required except for structural grade, building corrugated plates and general corrugated plates.

Requirements: It is generally required that after 180 bending of galvanized sheet, no zinc layer can be detached from the outer surface and no cracks or cracks can be found on the base of the sheet.
