Cold-rolled steel generally smaller

Cold-rolled coil refers to a steel strip that is directly rolled into a certain thickness with a roll at room temperature and rolled into a whole coil with a coiler. Compared with hot-rolled coils, cold-rolled coils have a brighter surface and higher finish, but will generate more internal stress and are often annealed after cold-rolling.

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.

Galvanized steel coil has a wide range of applications, and its advantage is that it has a long anti-corrosion period. It is mainly used for home appliances, office panels, roof sheets, automotive panels, construction and substrate of prepainted steel coils.

The cold plate is a hot-rolled steel strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Due to rolling at room temperature, no scale is produced, therefore, the cold plate has good surface quality and high dimensional accuracy, coupled with annealing treatment, its mechanical properties and process properties are better than hot-rolled steel sheets, in many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled sheet steel

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.

Cold rolled steel coil is a type of steel coil product developed from hot rolled steel coil and sheet, surface quality and dimension precision are quite low after hot rolling process, it can’t be used where surface quality and dimensions are required. Until now, cold rolled coils have been available and successfully used for a variety of applications.

Galvalume Coil composition by weight ratio of 55% aluminum,43.4% zinc,1.6% silicon, at high temperature 600 high temperature solidification and aluminized zinc plate surface is a unique smooth flat gorgeous star flower, the base color is silver white special coating structure makes it has excellent corrosion resistance

We have a large stock, so we have competitive prices and short delivery times. We support sample orders for customer, and can timely adjust product problems. We export to more than 20 countries in the world, we know the market, the quality and the price.

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

Galvanized steel coil, also known as galvanized coil, is a galvanized coil product. Galvanized coil, a steel material coated with zinc. The galvanized coil is the predecessor of the galvanized sheet. The galvanized coil is cut into sheets by equipment. The galvanized coil is placed on the shelf with a forklift or aerial crane, and then transferred, flattened and cut by the equipment.
