PRODUCT DESCRIPTION

Cold-rolled steel coils is the abbreviation of ordinary carbon structural steel cold-rolled sheet, also known as cold-rolled sheet, commonly known as cold plate, and sometimes it is mistakenly written as cold-rolled sheet. The cold plate is made of ordinary carbon structural steel hot-rolled steel strip, which is further cold-rolled into a steel plate having a thickness of less than 4 mm. Since rolling at normal temperature does not produce iron oxide scale, the surface quality of the cold plate is good, the dimensional accuracy is high, and the annealing process is superior to the hot-rolled steel sheet in mechanical properties and process performance, in many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheets.

Cold Rolled Full Hard Coil (CRFH) is a high-strength steel product widely used across various industries due to its superior mechanical properties, dimensional accuracy, and clean surface finish. As one of Steelhighsen’s core offerings, CRFH Coil is engineered to meet the needs of demanding applications where hardness and strength are essential.

What is CRFH Coil?

CRFH Coil, short for Cold Rolled Full Hard Coil, is produced by cold-rolling hot-rolled pickled coils without annealing. This results in a product with high hardness, increased yield strength, and limited formability. Despite its limited elongation, CRFH Coil offers excellent flatness, smooth surfaces, and consistent thickness, making it suitable for further processing such as galvanizing or painting.

In the steel industry, Cold Rolled Steel Coil Full Hard is recognized as an ideal base material for manufacturing galvanized steel, galvalume, and pre-painted steel, especially when cost-efficiency and dimensional stability are required.
