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.
