As a fundamental form of steel product, coil sheet steel—also known as steel coil or coiled sheet—has become the backbone of global manufacturing and infrastructure. Defined as thin, flat steel rolled into continuous coils for efficient storage, transportation, and processing, it is primarily composed of iron (≥97%) and carbon (0.02-1.5%), with optional alloying elements (manganese, […]

As a key structural steel product, the hot rolled H-beam has become indispensable in modern construction and industrial engineering due to its unique cross-sectional design and superior mechanical properties. Characterized by an H-shaped profile—comprising two parallel flanges connected by a central web—this beam is primarily manufactured from carbon steel (Fe ≥ 98%, C 0.12-0.22%) with

As one of the most widely used basic industrial materials, hot rolled carbon steel coil (HRCSC) plays an irreplaceable role in global manufacturing and infrastructure development. Composed primarily of iron (≥98%) and carbon (0.05-1.65%), with trace amounts of manganese, silicon, and phosphorus, this coil balances mechanical performance, cost-effectiveness, and processability. Its production process—conducted at high

As a premium grade alloy structural steel, 4340 steel bar has established itself as a cornerstone material in high-performance engineering sectors. Characterized by its balanced composition of iron, carbon, and key alloying elements—nickel (1.65-2.00%), chromium (0.70-0.90%), and molybdenum (0.20-0.30%)—this steel bar delivers exceptional tensile strength, toughness, and fatigue resistance. Its ability to withstand extreme mechanical

As one of the most widely used piping materials globally, carbon steel tube has become a cornerstone of industrial production and infrastructure construction. Composed primarily of iron and carbon, with trace amounts of other elements, this tube combines cost-effectiveness, mechanical strength, and adaptability, making it indispensable in fields ranging from energy transmission to mechanical manufacturing.

In the modern industrial system, the performance and stability of materials directly determine the quality and service life of end products. As a metal material integrating high strength, corrosion resistance, and easy processability, cold rolled galvanized steel coil has become an indispensable core component in automotive manufacturing, construction engineering, home appliance production, and many other

Galvanized steel coil, as a key steel product in modern industry and construction, continues to expand its application scope and steadily increase market demand. Galvanized steel coil undergoes a special treatment process, resulting in excellent rust and corrosion resistance. It is widely used in industries such as automotive manufacturing, home appliances, construction, and machinery. In

As one of the pillars of the national economy, the iron and steel industry has attracted much attention. In recent years, the steel industry has ushered in a series of important changes and opportunities, both in terms of market performance and domestic industrial policy direction. The steel industry is undergoing significant transformations driven by technological

Angle steel, also known as angle iron, is a long steel bar with an L-shaped cross-section. It is composed of two mutually perpendicular steel strips. It has both structural support and assembly flexibility. It is one of the most basic profiles in machinery manufacturing, construction engineering, and infrastructure construction. Angle steel, also known as angle

From the steel structure of skyscrapers to the precision components of automobile bodies, from home appliance casings to food packaging, steel coils have penetrated into every corner of production and life with various forms and properties. Steel coil, as one of the most representative forms of steel, is a cylindrical coil formed by rolling a
