Seamless Pipe is a durable material made from carbon steel, a steel alloy with iron and carbon. Because of its strength and ability to withstand stress, carbon steel pipe is used in a variety of heavy-duty industries like infrastructure, ships, distillers, and chemical fertilizer equipment.

Carbon steel reinforcing bars, also known as threaded steel bars or round steel bars, are special reinforcing steel materials used in concrete engineering. They enhance the overall strength of the structure by relying on the bond strength between the steel bars and concrete. The products are mainly divided into two categories: hot-rolled plain round steel bars (HPB series) and hot-rolled ribbed steel bars (HRB series). They are produced using a continuous hot rolling process, and the surface can be smooth round, spiral/herringbone/crescent-shaped ribs.

Carbon steel round bars, also known as plain round bars or round steel, are solid round bars made from carbon structural steel and high-quality carbon steel through processes such as hot rolling, cold drawing, precision drawing, and quenching and tempering. The surface finish is available in three forms: hot-rolled black skin, cold-drawn bright surface, and precision-ground mirror finish. The product materials cover ordinary carbon steel, high-quality carbon steel, and low-alloy structural steel. It boasts stable mechanical properties, excellent machinability, weldability, and forging performance, making it a fundamental and universal raw material for machining, hardware accessories, steel structures, fasteners, and mold auxiliary materials.

Carbon steel square bars, also known as square steel, are solid square-section carbon steel profiles. They are mainly manufactured using processes such as hot rolling, cold drawing, precision drawing, and precision grinding, and are available in three main surface types: hot-rolled black square bars, cold-drawn bright square bars, and precision-ground square bars. The products are manufactured using carbon structural steel, high-quality carbon steel, and low-alloy steel, resulting in regular cross-sections, excellent straightness, and stable dimensional tolerances. They also possess excellent cutting, welding, bending, forging, and heat treatment properties, making them a core raw material for machining, mold manufacturing, steel structures, hardware accessories, and equipment frames.

Carbon steel rectangular bars, also commonly known as rectangular steel, are solid rectangular cross-section carbon steel profiles produced through hot rolling, cold drawing, precision drawing, and precision grinding processes. They are mainly available in three surface finishes: hot-rolled black, cold-drawn bright, and precision ground. The products feature a flat cross-section, precise length and width dimensions, excellent straightness, and good cutting, welding, bending, stamping, and heat treatment properties. They are a common basic raw material for machining, steel structures, molds, hardware accessories, curtain wall supports, and grounding components.

Seamless carbon steel square tubes (commonly known as "carbon steel seamless square tubes") refer to hollow square cross-section steel tubes made of carbon steel (such as 20#, Q235B, Q345B, etc.) with no weld seams around the perimeter. They are formed by hot rolling, cold drawing or extrusion into seamless round tubes, combining the economy of carbon steel with the high strength and high reliability of seamless structures.

‌Carbon steel flat steel‌ is an alloy steel made of carbon as the main component. It is usually made by hot rolling or cold rolling and has specific mechanical properties and chemical composition. Its cross-section is rectangular with slightly blunt edges, the width is between 12-300mm, and the thickness is between 3-60mm‌
. Carbon steel flat bars are widely used in various structures and projects, such as bridges, buildings, automobile manufacturing, industrial pipelines, etc. In the field of construction, carbon steel flat steel is often used to make steel frames in reinforced concrete structures to improve the seismic performance and wind resistance of buildings‌

Cold-rolled carbon steel sheet is a low-carbon steel sheet with a thickness typically ≤4 mm, produced by cold rolling at room temperature (below the recrystallization temperature) from hot-rolled carbon steel coils. It features a smooth surface, high dimensional accuracy, and superior mechanical properties compared to hot-rolled sheets, and is widely used in stamping and forming applications in the automotive, home appliance, and hardware industries.
