Cold-Rolled Coil Steel

Here is placeholder text.

Cold Rolled Coil/Sheet (CRC) is a steel product manufactured from hot-rolled pickled coils, which undergo cold rolling at room temperature using a cold-rolling mill, followed by further processing steps such as annealing and leveling. Thanks to its unique production process, CRC boasts excellent surface quality, high dimensional accuracy, and superior mechanical properties—making it a critical foundational material for high-end manufacturing and precision processing industries. As an indispensable high-grade steel in modern industry, Cold Rolled Coil/Sheet serves as both the "face" and the "substance" of key sectors like automotive, home appliances, and electronics. Choosing the right type of CRC is a vital step in ensuring your products remain competitive in the market.

Galvanized Coiled Steel

Here is placeholder text.

Galvanized Steel Coil/Sheet refers to a steel product made from either cold-rolled or hot-rolled steel coils, where one or more layers of metallic zinc are continuously applied to the surface via a galvanizing process. This zinc coating acts as a sacrificial protective layer, effectively preventing the underlying steel substrate from corroding and rusting in natural environments, thereby significantly extending the steel’s service life.

Pickled Coiled Steel

Here is placeholder text.

Pickled Steel Coil/Sheet is produced from hot-rolled steel coils, where the surface oxide scale—primarily composed of FeO, Fe₂O₃, and Fe₃O₄—is removed using an acid-washing process. The material is then oiled and coiled, resulting in a product that serves as an intermediate between hot-rolled and cold-rolled coils, combining some of the key advantages of both. **As a substitute for hot-rolled steel:** Pickled steel offers a cleaner surface finish and more precise dimensions compared to hot-rolled sheets, addressing the limitations of hot-rolled products when used directly in exposed applications or high-quality environments. **As a substitute for cold-rolled steel:** With lower production costs than cold-rolled sheets while retaining the excellent ductility of hot-rolled materials, pickled steel emerges as a highly cost-effective choice for applications where extreme demands on surface quality or strength aren’t critical. **As a premium base material:** Pickled steel is the ideal raw material for manufacturing both cold-rolled and hot-dipped galvanized steel sheets.

Hot-rolled coil

Here is placeholder text.

Hot Rolled Coil/Sheet (HRC/HRS) is a steel product manufactured from slab stock—primarily continuous slabs—that is first heated in a furnace to temperatures above the recrystallization point (typically exceeding 1100°C). It is then rolled through a roughing mill and finishing mills, followed by laminar cooling to a specific temperature, and finally coiled into shape using a coiler.

Stainless Steel Coils

Here is placeholder text.

Stainless Steel Coil/Sheet refers to a product made from stainless steel billets, which are rolled into coils—either through hot or cold rolling processes. Its standout feature is its exceptional corrosion resistance, primarily due to the presence of at least 12% chromium (Cr) in the steel. When exposed to oxygen, chromium forms an ultra-thin, yet remarkably strong and dense chromium-rich oxide film (known as the passive layer) on the surface. This protective layer effectively prevents further oxidation and corrosion of the steel substrate. **Outstanding Corrosion Resistance:** Withstands corrosion from a wide range of media, including water, moisture, acids, alkalis, and salts. **High Strength and Hardness:** Offers superior structural integrity and excellent wear resistance. **Superior Formability:** Can be easily shaped through various processes such as cutting, bending, stamping, and stretching. **Excellent Heat Resistance:** Certain grades are capable of withstanding high-temperature oxidation, making them ideal for use in demanding, high-heat environments. **Hygienic and Aesthetic Appeal:** Features a smooth, non-porous surface that resists dirt buildup, making it easy to clean and sanitize. Additionally, its sleek, modern appearance adds a decorative touch, enhancing both functionality and visual appeal.

Profile

It refers to solid, straight bars of metal that have been shaped through plastic deformation into specific cross-sectional forms and dimensions. Profiled materials come in a wide variety of types and specifications, making them highly versatile and playing a crucial role in rolling production.

Pipe materials
