Carbon steel coils can be divided into hot-rolled coils and cold-rolled coils according to the production process. Cold-rolled coils are made of hot-rolled coils and rolled below the recrystallization temperature. Common grades are: SPCC, SPCD, SPCE, ST12-15, DC01-06.

Common materials are Q235B, Q345B, SPHC, 510L, Q345A, Q345E, etc.

The difference between hot rolled coil and hot rolled sheet

Hot-rolled coils, also known as hot-rolled coils, are strips made of slabs (mainly continuous casting slabs) as raw materials, which are heated by rough rolling mills and finishing mills. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to a set temperature by laminar flow, and is rolled into a steel strip coil by a coiler.

Hot-rolled sheet, also known as hot-rolled sheet, is made of cooled steel strip coils. According to the different needs of users, through different finishing lines (leveling, straightening, cross-cutting or slitting, inspection and weighing, packaging and signs, etc.) to be processed into steel plates, flat rolls and slit steel strip products.

Hot-rolled coil is a development of the varieties of steel the current markei demand many concentraced in the automobile industry,compressor industry,machinery manufacfuring,processing and distribution industry,fan industry,motorcycle industry,steel furniture,hardware accessories,electrical cabinets and shelves of various shapes,such as stamping parts. As technology advances,hot-rolled pickling coil has been related to household appliances,containers,electrical control cabinet and other industrise,including the use of pickling hot-rolled coil instead of cold plate in some industry development is rapid.
