What are advantages of galvanized steel?
Because it is produced through applying Zn coat on both faces by hot dip process. It enjoys both the physical protective feature and the electrochemical protective property of Zn.
>>Machinability: It can satisfy the processing requirements of rolling, coiling and others processes alike.
>>Thermal resistance: Common HDG steel plate normally works under 230℃, and has its color changed at 250℃, however, Galvanized steel plate can sustain the environment at 315℃ for long time.
>>High reflectivity: Reflection ability of heat and light is twice as much as those of hot-dip zinc steel sheet, and its reflectivity is more than 0.70, which is an ideal construction materials of saving energy.

 

1, normal zinc flower coating: galvanized coil zinc layer in the normal process of condensation, zinc crystals grow up at will with significant zinc flower crystal phase of the coating.

2, small zinc flower coating: zinc layer in the whole process of condensation, zinc crystal is limited by human factors, produce as fine as possible zinc flower coating.

3, zinc free flower coating: according to the adjustment of the composition of the bath obtained, do not have visible zinc flower crystal phase, uniform surface coating.
4, zinc nonferrous metal coating: according to the hot dip galvanized steel chain for conditioning treatment after bath, make all plating into zinc and iron aluminum alloy layer, the coating appearance show dark dark gray, no metal texture, easy to take off a layer in the strong forming process, applicable in addition to the general cleaning, no further solution can go up lacquer coating.

5, difference thickness coating: on both sides of galvanized steel plate, provisions have different zinc layer net weight coating.

6, finishing: finishing is for the following one or dozens of purposes, and the development of a fine shape variable cold stamping production and processing of galvanized steel plate. Improve the surface shape of galvanized steel plate or suitable for decorative design coating; The finished products can not see the load line caused by the production and processing should be reduced to less.

Galvanized coil is the main use of what

Galvanized coil means that the cold rolled sheet is infiltrated into the melted zinc tank, so that the surface of the cold rolled sheet is bonded with a layer of zinc. Galvanized coil can be divided into hot galvanized sheet coil and cold galvanized hot galvanized sheet coil, at this stage, the key choice of continuous hot galvanized processing technology manufacturing, that is, the plate of thick steel plate continuous dip in the melt zinc plating tank made of galvanized steel plate. Because galvanized coil has high surface cost performance, is conducive to production and processing, high cost performance characteristics, so it is widely used as engineering construction, household appliances, cars, utensils, transportation and ancestral industries. Very steel structure engineering, automotive industry, steel warehouse production and manufacturing industries.
