Stainless steel pipe: core material for transportation and support under corrosion-resistant tubular structure

Stainless steel pipe is a tubular product made from iron, containing 10.5% or more chromium and alloying elements such as nickel and molybdenum, and manufactured through forming, welding, or seamless processing. It inherits stainless steel's core properties of corrosion resistance, sanitation, non-toxicity, and high strength, while also utilizing its tubular structure to provide fluid transport and structural support. It has become a key alternative to carbon steel pipe in industries requiring high corrosion resistance, such as food, medicine, chemical energy, and architectural decoration.

Copper coil: the core carrier for batch application of copper materials in coil form

Copper coil is a coiled product made from pure copper or copper alloys, directly coiled after smelting, continuous rolling, and heat treatment. It inherits copper's core properties of high electrical and thermal conductivity, excellent ductility, corrosion resistance, and aesthetics. Its coiled structure offers the industrial advantages of continuous processing, efficient transportation, and flexible cutting. It has become a key material in mass production applications such as electronics, architectural decoration, and precision manufacturing, effectively addressing the challenges of low processing efficiency and high costs associated with single-sheet copper coils.

Copper sheet: a high-performance metal sheet that combines functionality and aesthetics

Copper sheet is a sheet product made from pure copper or copper alloys through smelting, rolling, and heat treatment. Copper's unique high electrical and thermal conductivity, excellent ductility, and distinctive metallic luster make it a specialized metal sheet that combines both functionality and aesthetics in applications such as electronics, architectural decoration, industrial heat dissipation, and precision manufacturing. It cannot be fully replaced by materials like steel and aluminum.

Color coated coil: the core carrier for batch application of color coating in coil form

Color-coated coil (also known as color-coated steel coil) is a composite coil product made from a metal coil (such as cold-rolled coil, galvanized coil, or stainless steel coil). After surface pretreatment (degreasing, phosphating, and passivation), continuous roll-coating of an organic coating (such as polyester or fluorocarbon), and high-temperature curing, it is directly wound into a finished product. It combines the combined advantages of color-coated materials—metal strength and a weather-resistant, aesthetically pleasing coating—with the advantages of a roll-shaped structure that allows for continuous processing, efficient transportation, and flexible cutting. This makes it a key material for industrial mass production in sectors such as construction, home appliances, and transportation. I. Definition and Classification of Color-Coated Coil

Color-coated sheet: Multifunctional metal sheet empowered by coating

Color-coated steel sheets (also known as color-coated steel sheets) are composite sheets made from a metal substrate (such as cold-rolled steel, galvanized steel, or stainless steel). After surface pretreatment (degreasing, phosphating, and passivation), they are coated with one or more layers of organic coatings (such as polyester or fluorocarbon) and then cured by baking. They combine the strength of the metal substrate with the weather resistance and aesthetics of the coating, meeting the dual demands of "beauty and performance" in applications such as architecture, home appliances, furniture, and transportation, making them a highly effective alternative to traditional painted steel sheets.
