What Is Cold Rolled Steel Strip?

Cold rolled steel strip is a popular steel material produced by HR steel and has been pickled. It is famous because of its high quality, material saving, easy processing, and high dimensional accuracy. According to the edge state of the cold rolled steel strip, it is divided into two types: cut edge and uncut edge. Moreover, the cold rolled strip mainly produces steel pipes, hardware products, home appliances, building materials, steel sheets, etc. For further details, please keep reading.

Note: 1. German standard: DIN1614 specifies a width ≥600mm for a wide steel strip.

2. Chinese standard: there is no clear provision, but in the industry with a wide 400-900mm, called medium wide steel strips; width ＞900mm is a wide steel strip

What Is Cold Rolled Steel Strip Used For?

Cold rolled steel strip refers to the conveyor belt made of hot-bonded steel as the raw material for the traction and support components of the belt conveyor, and can also be used for kwanza goods. It can meet the industrial production needs of various metal or mechanical products in different industrial sectors. The cold rolled steel strip is mainly supplied in rolls, with good surface quality, easy processing, wide application, and high precision. Due to its special features, cold rolled steel strips are suitable for the production of household electrical appliances, food cans, precision instruments, steel pipes, etc. In addition, automobile manufacturing, the construction industry, and some durable products require a large amount of cold-rolled steel strips.

Cold Rolled Steel Strip Manufacturing Process

Cold rolling is an important metal processing technology, mainly used in producing and processing steel. The production process of cold rolled steel strips mainly includes steel coil unwinding, degreasing washing, dust removal and rust removal, steel strip pretreatment, rolling cold coil, cutting size, oil removal, inspection, packaging, etc.

Cold Rolled Strip Package

Cold-rolled steel strip packaging forms are generally divided into bare packaging, simple packaging, and fine packaging three kinds. We can pack according to your requirements. To ensure the packaging reliability of the cold rolled steel strip packaging process, we will consider the product characteristics and actual needs for you to choose the appropriate packaging materials. Common packaging materials include wooden pallets, plastic packaging belts, and cartons. The wooden pallet has a high bearing capacity and service life, which can effectively protect the cold rolled steel strip. The strength and toughness of the plastic packaging belt are better, which can ensure that the cold-rolled steel belt will not be loosened by vibration during transportation. Carton boxes provide the protection needed for cold-rolled steel strips and can be easily handled and stored. We generally recommend our customers use wooden pallet packing.

4 Tips For Cold Rolled Strip Storage

Although there is dual protection of anti-rust oil and gas phase anti-rust paper on the surface of the steel plate, if it is in a humid environment for a long time, the water on the surface will gradually cause corrosion on the surface of the steel strip, so it is necessary to pay attention to:

1. Do not be soaked by water, store indoors, and avoid open stacking.

2. If the steel coil is exposed to rain or condensation, it should be unpacked immediately and dried quickly to remove moisture, and used as soon as possible.

3. The steel coil should be stored in the factory condition as far as possible and should not be stacked in multiple layers to avoid deformation of the steel coil.

4. The mechanical properties of steel coil or steel plate are generally guaranteed for six months, and the aging caused by long-term storage of steel coil makes the mechanical properties change, so it should be used as soon as possible. The principle of “first purchase, first use” when used, especially in coastal and industrial environments, should shorten the storage period.
