Section steel is a kind of strip steel with certain section shape and size. 
According to the section shape, the section steel is divided into simple section steel and complex section steel .
The former refers to Square steel, Round steel, Flat steel, Angle steel, Hexagonal steel, etc;
The latter refers to I-beam, Channel steel, Rail steel, Window frame steel, Bending section steel, etc.

H-section steel is a revolutionary and economically savvy choice, renowned for its precisely optimized cross-sectional area and outstanding strength-to-weight ratio. Its iconic name is inspired by its resemblance to the letter 'H', which is not just a shape but a symbol of strength. The unique right-angle configuration of its components grants it exceptional bending resistance, straightforward construction, and significant cost efficiency, all while reducing the overall weight of structures. These remarkable attributes have propelled its widespread application across a multitude of industries and sectors.

Carbon Steel Flat Rectangle Bar General Introduction:
Flat steel includes the common hot rolled flat bar and cold drawn flat steel bar. Its width is 12-200mm, the thickness is 3-30mm and the length is 3m-12m or as per the client's request. MS rectangle bar is mainly used in the form various stress components according to the different needs of the structure, and it can also be used as a connection between components. Mild steel flat bar is widely used in the various construction structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves etc.

Carbon steel bar is a solid long product with carbon content below 2%. Available in round, square, flat and hexagonal shapes, it offers excellent machinability and weldability. Widely used in construction, machinery and automotive industries, common grades include A36, 1045, and Q235. Provides good strength-to-cost ratio for structural applications.

ST37 Carbon Steel Bar is a common structural steel grade (DIN standard) with good weldability and machinability. Featuring low carbon content (≈0.17%) and tensile strength of 370MPa, it's widely used in construction, machinery and general engineering. Equivalent to Q235 (GB) and S235JR (EN).

SGCC Carbon Steel Bar is a high-quality carbon steel product, typically with low-medium carbon content (0.05-0.25%). Offering excellent strength, machinability and weldability, it's commonly supplied as round/flat/square bars for construction, machinery and fastener applications. Comparable to Q235 or A36 steel, it provides reliable performance for structural uses.

Square Steel is a versatile and strong steel product with a square-shaped cross-sectionIt is widely used in construction, manufacturing, and structural applications. SquareSteel offers excellent strength, durability, and load-bearing capacity. It is commonlyused for framework, support structures, and various fabrication projects

10# Carbon Steel Pipe is a low-carbon steel pipe (0.07-0.13% C) with excellent plasticity and weldability. Commonly used in low-pressure fluid delivery, structural applications, and machinery parts. Complies with GB/T 8163 standard, offering good cold-working performance. Typical applications include water/gas systems and mechanical components. Equivalent to ASTM A53 Grade A.

Q195 carbon steel pipe is a low-carbon steel pipe with a low carbon content (approximately 0.06%-0.12%), featuring a yield strength ≥195 MPa. It exhibits good plasticity, weldability, and workability, and is typically manufactured as straight seam welded pipe or hot-rolled seamless pipe. Commonly used for low-pressure fluid conveyance (water, air) and simple support structures, it offers low cost and suits civil and light industrial applications with minimal strength requirements.
