Necessary for making sheet metal! Detailed explanation of hot dip galvanized steel characteristics

Product Name: hot dip galvanized steel plate

Code: SPGC

Hardness: hRb1 / 2H = 74 ~ 89 1 / 4H = 65 ~ 80 1 / 8h = 50 ~ 71 H = above 89

Tensile strength: above 40 ~ 55kgf / mm2.

Material thickness: 0.4 ~ 3.2mm. Materials above 3.2mm are difficult to buy and are generally replaced by electroplated white zinc.

Material width: the maximum width is 5 ‘(1524mm), generally 4’, i.e. 1219mm or 1250mm. Any size less than 1524mm can be cut as required.

Material length: any size can be cut as required. Generally 8 ‘, i.e. 2438 mm or 2500 mm.

Material characteristics: 1. The metal has white luster and patterns, and the surface is not easy to rust, but white rust spots will be produced due to corrosion.

Generally, no surface treatment is required.
Can not do electroplating (colorful zinc plating, white zinc plating, nickel plating, tin plating…).
Suitable for refrigeration, air conditioning, heavy motor and roof structural parts. Specific gravity: 8.25 weight calculation: length (m) × Width (m) × Thickness (mm) × Specific gravity = kilogram (kg), e.g. spgc2 0 ×1220 × 2440 weight: 2.0 × 1.22 ×2.44 × 8.25 = 49.1kg, another example: spgc1 0 × one thousand × 2000 weight: 1 × one × two × 8.25=16.5kg

Note: 1. The general tolerance of material thickness is + 0, – 0.08, that is, the plate thickness is 2.0mm, and the actual measurement may be only 1.92mm.

A micrometer shall be used to measure the material thickness, and a cursor caliper shall not be used.
If bending is required, pay attention to whether the zinc layer on the surface falls off, and remove the zinc powder of the lower mold in time.
