Welded square tube is a square cross-section steel tube formed by cold bending of steel plates or steel strips and then welding. It has the characteristics of stable structure, flexible processing and moderate cost. It is widely used in construction, machinery, transportation, furniture and other fields.

Welded Steel Pipe is a steel pipe made by welding steel plates or steel strips after curling and forming. It is widely used in industry, construction, energy, transportation and other fields.

Seamless Steel Pipe is a weldless steel pipe made by hot rolling, cold rolling or cold drawing. It is widely used in fields with strict requirements on material properties due to its uniform metal structure, high strength and high pressure resistance.

Galvanized pipe is a steel pipe with a layer of zinc (hot-dip galvanizing or electro-galvanizing) on ​​the surface of the steel pipe. It has the characteristics of corrosion resistance, long service life and moderate cost.

Angle steel is a kind of L-shaped steel, usually made by hot rolling or cold bending process. It has the characteristics of stable structure, easy installation and strong bearing capacity. It is widely used in construction, machinery, electricity, transportation and other fields.

H-shaped steel is a type of steel with a cross-sectional shape similar to the letter "H". Due to its excellent mechanical properties and efficient material utilization, it is widely used in construction, bridges, machinery manufacturing and other fields.

I-beam (also known as H-beam or I-beam) is named because its cross-sectional shape resembles the Chinese character "工". It has high bending strength and stability and is widely used in engineering fields such as construction, machinery, and bridges.

Steel is a long strip of steel with a groove-shaped cross-section. Because it has protruding flanges on both sides (commonly known as "edges"), it has good bending, torsion and load-bearing capabilities, and is widely used in construction, machinery, transportation and other fields.

Flat steel is a long strip of steel with a rectangular cross-section. It is usually thin (commonly 3~60mm) and narrow (10~200mm). It has the characteristics of flexible processing, high surface utilization, and easy connection. It is widely used in construction, machinery, hardware, decoration and other fields.

Hot-rolled coil (hot-rolled coil) is a kind of steel produced by high-temperature rolling process. It has the characteristics of high strength, good toughness and low cost. It is widely used in the fields of construction, machinery, automobiles, home appliances, etc. In construction, it is often used in steel structure beams and bridges; in machinery manufacturing, it can be used as a structural part or component base material of engineering equipment; in the automotive industry, it is mostly used for body frames and chassis parts.

Cold rolled steel coil (cold coil) is a steel product processed by cold rolling process (rolling at room temperature). It has the characteristics of smooth surface, precise size and excellent mechanical properties. It is widely used in fields with high requirements on precision, strength and surface quality.

As the "skeleton" of concrete structures, steel bars are an indispensable key material in construction projects. They are used in all kinds of civil engineering projects, from high-rise buildings to cross-sea bridges, from underground pipe galleries to nuclear power plants. Steel bars are silently playing a vital role in strengthening structures.

Patterned plates (usually metal plates with raised or sunken patterns on the surface, such as patterned steel plates, aluminum patterned plates, etc.) are used for their anti-slip, wear-resistant, decorative and other properties.

Hot rolled steel plate is a steel produced by high temperature rolling process, which has the characteristics of high strength, good toughness and excellent processing performance.

Cold rolled steel sheet is a steel produced by cold rolling process (rolling at room temperature), which has the characteristics of smooth surface, precise size, high strength and good formability.
