Gi Strip 585*1.2mm 585*1.6mm 585*1.8mm Grade 195 Galvanized Steel Strip
Galvanized steel strip is processed by ordinary steel strip pickling, galvanizing, packaging and other processes. It is widely used because of its good anti-corrosion performance. It is mainly used to make metal products that are cold-worked and no longer galvanized. For example: metal products such as light steel keels, peach-shaped columns for guardrails, sinks, rolling doors, bridges, etc.
Carbon Steel Details:
Common carbon steel grades: Q195, Q215, Q235, Q255, Q275, etc.
Carbon alloy steel: 1008(08F), 1010(10#), 1015(15#), 1020(20#), 1025(25#), 1040(40#), 1045(45#), 1050(50#), 15Mn, 20Mn, 30Mn, 40Mn, 45Mn, 50Mn, etc.
Carbon tool steel: T7, T8, T8Mn, T10, T11, T12, etc
Each Carbon Steel Coil is being produced with care to quality by decreasing carbon contend and giving appropriate heat treatment.
Even distribution of steel coil various grades of carbon steel coil in accordance with ASTM JIS DINEN etc.
There is large amount of spot inventory and each carbon steel coil is subjected to modern physical and chemical testing.
There are many factors affecting the size of zinc flowers. When the zinc liquid composition has the conditions for the formation of zinc flowers, the following factors will affect the size of zinc flowers:
(1) Raw material: the thicker the raw material steel plate, the smaller the surface roughness, the larger the zinc flower.
(2) Cooling rate: the faster the cooling rate, the shorter the crystal growth time, the smaller the zinc flower.
(3) Number of crystal nuclei: The size of zinc flower is closely related to the number of crystal nuclei of zinc flower. When the surface of steel base is rough or the surface cleanliness is poor, the zinc flower is relatively small. Zinc grains are formed on steel base, and the more nuclei there are, the smaller the zinc flowers will be. This principle is used in the production process of small zinc flowers.
(4) Other factors (production environment, etc.).

The application fields of cold-rolled coils are very wide, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, canned food, etc.
The product size of cold-rolled coils is accurate, the
thickness is uniform, and the thickness difference of the
coils generally does not exceed 0.01-0.03mm or less,
which can fully meet the requirements of high-precision
tolerances.
- vailable to extremely thin strips that cannot be produced by hot rolling (the thinnest can reach 0.001mm or less).
The surface quality of cold-rolled products is superior,
and there are no defects such as pits and pressed iron
oxide scales that often occur in hot-rolled coils. And
according to the requirements of users, it can produce
coils with different surface roughness (glossy surface or
hemp rough surface, etc.) to facilitate the processing of
the next process.
The mechanical properties and technological
properties of cold-rolled steel coils are very good (such
as higher strength, lower yield limit, good weight deep
drawing performance, etc.).
High-speed rolling and full continuous rolling can be
realized, with high productivity.
1. Appearance and surface quality: Cold-rolled steel coil is better in surface quality (such as Surface roughness) than hot plate because it is obtained by cold rolling and some surface finishing is carried out at the same time. Therefore, if the product after the sequence of painting, such as coating quality, there are higher requirements, the general choice of the cold plate. The hot plate is divided into the pickling plate and the unpickling plate. The surface of the pickling plate becomes the normal metal color because of pickling, but the surface of the unsold-rolled plate is not as high as that of the cold-rolled plate, or the existence of ferrosoferric oxide layer, colloquially it is fire-roasted, and if the storage environment is not good, usually with a little embroidery.
2. Properties: In general, the Mechanical Properties of hot and cold-rolled steel coil are considered to be the same in engineering, although there is a certain amount of work hardening during cold rolling, (but not rule out the case of strict mechanical performance requirements, it needs to be treated differently), cold-rolled steel coil usually than hot plate yield strength slightly higher, surface hardness is also higher, how specific need to see cold plate annealing degree. However, the strength of the annealed plate is higher than that of the hot plate.
3. Forming performance: Because the performance of cold and hot-rolled steel coil is basically not too much, so the forming performance of the influence factor depends on the difference of its surface quality, because the surface quality is the cold-rolled steel coil to be better, so generally speaking the same material steel plate, the appearance of cold plate is better than that of the hot plate.
