3C certified wire rod is hot-rolled round steel with a diameter of 5-22mm or special-shaped steel equivalent to this cross-section. Because they are delivered in the form of raw materials, they are collectively called raw materials. The wire cross-section circumference is very small, and the general product specification diameter is 5-13mm. According to different rolling mills, it can be divided into high-speed wire rod (high wire) and ordinary wire rod (ordinary wire).

UL wire is generally made of ordinary carbon steel and high-quality carbon steel. According to the steel distribution catalog and usage, wire rods include ordinary low carbon steel hot-rolled discs, high-quality carbon steel wire rods, carbon welding rod wire rods, adjustable threaded wire rods, steel wire rope wire rods, musical instrument wire rods, stainless steel wire rods, etc.
