s235 Cold Rolled zinc Steel Sheet steel coil

Cold-rolled steel coils are made of hot-rolled coils and rolled at room temperature below the recrystallization temperature. Cold-rolled steel has good performance. That is, cold-rolled steel can be thinner and more precise.

It is an emerging galvanized and galvalume steel, tinplate sheet, PPGI Cold Rolled Ss340 Steel Material Metal Galvanized Steel Coil,hot and cold rolled sheet, ppgi ppgl company integrating production, supply, sales and export. After years of development and improvement, has become the large international steel companies. It is a large-scale PPGI,Galvanized steel ,Carbon steel industry group integrating smelting, processing, domestic trade, import and export.

Cold Rolled zinc Steel Sheet steel coil Galvanized Steel Sheet is defined as a carbon steel sheet coated with zinc on both sides.

It is produced through a process of metal coating which involves passing cold rolled coils through a zinc pot. The process ensures the adherence of zinc to the surface of steel sheet.The zinc layer provides excellent corrosion resistance so that it can prolong the service life
of the product.

Ral7016 Dx51d PPGI Gi cold rolled Steel Coil is produced through a process of metal coating which involves passing cold rolled coils through a zinc pot. The process ensures the adherence of zinc to the surface of steel sheet.The zinc layer provides excellent corrosion resistance so that it can prolong the service life of the product.

Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristics.

Cold rolled galvanized steel coil
It is cold-rolled or hot-rolled, long and narrow long steel plate is coated with a layer of raw materials called (zinc, aluminum) to varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized strip steel matrix undergoes a complex physical and chemical reaction with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a compact structure. The alloy layer is integrated with the pure zinc layer and the strip steel matrix. Therefore, its corrosion resistance is strong.

Coils are divided into chilled coils and cold rolled coils. The difference between the two is that in appearance, the general chilled coil is slightly black; the surface quality, structure, and dimensional accuracy of the cold-rolled sheet are better than that of the chilled coil; in terms of performance, because the hot-rolled coil goes through the cold rolling process The directly obtained chilled coils undergo work hardening during cold rolling, resulting in an increase in yield strength and some residual internal stress, and the external performance is relatively “hard”, so it is called chilled coils.

Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides.Galvanized steel coils are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 30 – 275 grams per squaremeter

ASTM Cold Rolled Dipped GI Galvanized Steel Coil GI Strip Coil is hot-rolled steel that has been cleaned of iron oxide scale (pickled) and reduced to a specific thickness through a series of rolling stands (tandem mill) or passed back and forth through a reversing rolling mill. The steel can be heated to controlled temperatures (annealing) depending on mechanical property requirements, and final rolled to the desired thickness.

Cold-rolled galvanized sheet is a kind of galvanized steel sheet. Steel sheets are classified into two types: hot-rolled and cold-rolled. Cold-rolled sheet is flat, rectangular, and can be directly rolled. Cold rolling is a steel sheet in which the steel sheet is further thinned to a target thickness at room temperature.

Cold-rolled is processed from hot-rolled sheets at room temperature. Although the temperature of the steel sheet will be heated during the processing, it is still called cold-rolled. Due to the continuous cold deformation of hot rolling, the mechanical properties are relatively poor and the hardness is too high. It must be annealed to restore its mechanical properties, and those without annealing are called hard rolled coils. Hard-rolled coils are generally used to make products that do not require bending or stretching, and those with a thickness of less than 1.0 are rolled on both sides or four sides with good luck.

Cold coil is made of hot rolled coil at room temperature and below the recrystallization temperature, including plate and coil, of which the sheet delivered is called steel plate, also known as box plate or plate; the long length and delivered in coil is called steel strip, also known as coil plate.

Galvanized steel cold rolled coil has a wide range of uses, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans, etc., industrial panels, roofing and siding for painting, etc.

The material composition of the product is mainly iron carbon alloy, generally containing a small amount of silicon,manganese, sulfur and phosphorus. Different brands correspond to different hardness, thermoplastic, plasticity and weldability. If you don’t understand, you can tell us your requirements.

Cold rolled coil could supply better control of thickness, shape, width, surface finish, and other special quality features that compliment the emerging need for highly engineered end uses. Take construction projets for example: steel sheds, industrial buildings, and garages.
