彩钢卷经热压和冷压成卷。为了便于储存、运输和加工，分为热轧卷和冷轧卷。彩钢卷主要销往大客户，一般用户没有开卷设备或使用受到限制。彩钢卷，又称钢卷。钢是通过热压和冷压轧制的。为便于储运，便于各种加工（如加工成钢板、钢带等）

成型线圈主要有热轧卷和冷轧卷。热轧钢卷是钢坯再结晶前加工的产品。冷轧钢卷是热轧钢卷的后续加工。彩钢卷一般重量在15-30t左右，今年我国热轧产能继续扩大，现有数十条热轧生产线，部分项目即将建成或投产。彩钢卷的销售主要针对大客户，一般用户没有开卷设备或使用量有限。

彩钢卷的后续加工将是一个很有前途的产业。当然，目前大型钢厂都有自己的开卷整平工程。加热后，带钢由粗轧机和精轧机制成。最后一台精轧机生产的热轧带钢经层流冷却至设定温度，再经卷取机轧制成带钢。冷却后的带钢卷，根据用户的不同需要，采用不同的精整线（调平、矫直、横切或纵切、检验、称重、包装、标识）加工成钢板、扁卷和纵切带钢产品。
热轧钢板具有强度高、韧性好、易加工、焊接性好等优良性能，广泛应用于造船、汽车、桥梁、建筑、机械、压力容器等制造业。随着控制热轧尺寸精度、形状和表面质量的新技术的发展，以及新产品的出现，热轧板带产品得到了越来越广泛的应用，市场竞争也越来越激烈。
热轧钢板产品包括钢带（卷）及其剪切钢板。钢带（卷）可分为直发卷和精轧卷（分卷、平卷和纵剪卷）。主要产品：热连轧按材质和性能可分为普通碳素结构钢、低合金钢和合金钢。按用途不同，可分为：冷成型钢、结构钢、汽车结构钢、耐腐蚀结构钢、机械结构钢、焊接气瓶及压力容器钢、管线钢等
Color steel coil is formed into coils by hot pressing and cold pressing. In order to facilitate storage, transportation and processing, it is divided into hot-rolled coil and cold-rolled coil. Color steel coil is mainly sold to large customers, and general users do not have uncoiler equipment or use is limited. Color steel coil, also known as coil steel. The steel is rolled by hot pressing and cold pressing. In order to facilitate storage and transportation, and facilitate various processing (such as processing into steel plate, steel strip, etc.).
Forming coil is mainly hot-rolled coil and cold-rolled coil. Hot rolled coil is a product processed before recrystallization of billet. Cold rolled coil is the follow-up processing of hot rolled coil. The general weight of color steel coil is about 15-30t. This year, China's hot rolling production capacity continues to expand, there are dozens of hot rolling production lines, and some projects are about to be built or put into production. The sales of color steel coils are mainly aimed at large customers, and the general users do not have uncoiler equipment or use a limited amount.
The follow-up processing of color steel coil will be a promising industry. Of course, at present, large steel mills have their own uncoiling and leveling projects. After heating, the strip is made from roughing mill and finishing mill. The hot steel strip from the last finishing mill is cooled to the set temperature by laminar flow, and then rolled into steel strip by coiler. The cooled steel strip coil is processed into steel plate, flat coil and longitudinal cut steel strip products by different finishing lines (leveling, straightening, cross cutting or longitudinal cutting, inspection, weighing, packaging and marking) according to different needs of users.
Due to its high strength, good toughness, easy processing, good weldability and other excellent properties, hot rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries. With the development of new technologies for controlling the size accuracy, shape and surface quality of hot rolling as well as the appearance of new products, hot rolling steel plate and strip products have been more and more widely used and become more and more competitive in the market.
Hot rolling steel plate products include steel strip (roll) and steel plate with its shear. The steel strip (roll) can be divided into straight hair roll and finishing roll (divided roll, flat roll and longitudinal cut roll). Main products: hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their material and performance. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder and pressure vessel steel, pipeline steel, etc.
