Description

On the surface of the steel plate, you can see a crystal pattern, that is large spangle galvanized. The structure of zinc-flowered crystal shows that only located on the surface of steel plate that can form hexagonal star or snowflake. If the arm is not in the plate plane, the shape of the hexagonal star changes.

Spangle usually refers to the appearance of the grains formed after the hot galvanized sheet is pulled out of the zinc pot and the layer is cooled and solidified. The size, brightness and surface morphology of zinc flowers depend on a series of factors, but mainly relates to the composition of zinc layer and cooling method. Zinc flowers are produced by reducing the solidification temperature of the liquid zinc. Our product has beautiful zinc flowers on its surface, which is one of its distinguishing features from other plating plates.


Features

The surface of the plate is beautiful, with flower shape zinc crystal pattern.

The galvanization layer is firm, have excellent air corrosion-resistant performance.

Good welding and cold forming properties.

More Info

Zinc flowers larger than 3mm in diameter can be identified by the naked eye as large zinc flowers, also known as normal or natural zinc flowers. (The internationally recognized best size is 8~12mm.)

(1)Influence of alloy elements.The size of zinc flower is related to the amount of addition. The larger the content of zinc flower, the larger the content of zinc flower, and the smaller the content of zinc flower.

(2)Impact of the original plate. The thicker the original plate, the smaller the roughness, the larger the zinc flowers.

(3)The effect of cooling rate. The slower the cooling rate, the longer the crystals grow, and the larger the zinc bloom.

(4)Effect of crystallization center. During the solidification process of the galvanizing layer, the size of the zinc flowers is determined by the number of crystal nuclei: the more the crystal nuclei, the smaller the zinc flowers, and the less the crystal nuclei.

(5)Influence of zinc thickness. The thicker the zinc layer, the longer the solidification, so the larger the zinc bloom.


Application:

It is widely used in construction, packaging, railway vehicles, agricultural machinery manufacturing and daily supplies.
