The recommended standard thickness, length and width of galvanized sheet and its allowable deviation are listed in the relevant product standards. In general, the thicker the galvanized sheet allows the greater the error, rather than fixed 0.02-0.04 mm, the thickness of the deviation according to the yield, tensile coefficient and other different and have different requirements, the length and width deviation is generally in 5mm, the thickness of the sheet is generally between 0.4-3.2.

DX51D Galvanized Surface

(1) the surface state: galvanized sheet due to different treatment methods in the plating process, the surface state is also different, such as ordinary zinc flower, fine zinc flower, flat zinc flower, no zinc flower and phosphating treatment of the surface. The German standard also provides for surface grades.

(2) galvanized sheet should have a good appearance, no harmful defects to the use of the product, such as no plating, holes, rupture and scum, more than plating thickness, abrasion, chromic acid dirt, white rust, etc. Foreign standards are not very clear on the specific appearance defects. When ordering, the specific defects should be specified in the contract.

DX51D Galvanized Mass of Zn coat

Galvanization standard value: Galvanization is a widely used effective method to indicate the thickness of zinc layer of galvanized sheet. The unit of galvanizing quantity is g/m2. Japan, the United States and Germany standards on galvanized sheet steel galvanized provisions detailed as follows.

Mechanical Property

(1) tensile test:

Performance indicators: in general, only structural, tensile and deep drawing galvanized sheet has tensile performance requirements. The structural galvanized sheet requires yield point, tensile strength and elongation, etc. For stretching only the elongation is required. See product standards in Section 8 for specific values;

Test method: The test method is the same as the general thin steel sheet test method, see the relevant standard provided by "8" and the test method standard listed in "ordinary carbon steel sheet".

(2) Bending test:

Bending test is the main item to measure the process performance of sheet metal, but the requirements of all kinds of galvanized sheet are not consistent in the national standards, the American standards do not require bending and tensile test except for the structure grade. In Japan, bending tests are required except for structural level, building corrugated plates and general corrugated plates.

Requirements: general requirements galvanized sheet bending 180, the outer surface shall not be separated from the zinc layer, the substrate shall not be cracked and fracture.

Chemical Component

The requirements of the chemical composition of galvanized sheet substrate, national standards are different, the national standard is generally the detection of carbon, manganese, phosphorus, sulfur, silicon content.

Packaging

It is divided into two kinds: galvanized sheet cut into fixed length and galvanized sheet packing with coil. Generally packed in iron sheet, lined with moisture-proof paper, tied on the bracket with iron kidneys. Strapping should be firm in order to prevent the inner galvanized sheet from rubbing against each other.
