C-shaped steel is a commonly used cold-bent thin-walled steel, named for its "C"-shaped cross-section.

1. Basic characteristics

Cross-section shape: C-shaped, with excellent cross-section performance, high strength and light weight.

Processing method: Mainly automatically processed and formed by C-shaped steel forming machine, made by hot coil cold bending process.

Material: Usually ordinary carbon steel, low alloy steel or stainless steel, etc. According to different uses and environmental requirements, surface treatments such as galvanizing and painting can be performed to improve its corrosion resistance and aesthetics.

2. Specifications and classifications

Specifications: C-shaped steel has a variety of specifications, such as C50, C100, C150, etc. The number represents the width of the C-shaped steel section (in millimeters). At the same time, according to different heights, C-shaped steel purlins are divided into five specifications: 80, 100, 120, 140, and 160.

Classification: including galvanized C-shaped steel, hot-dip galvanized cable tray C-shaped steel, glass slot C-shaped steel, glass curtain wall C-shaped steel, wiring trough C-shaped steel and other types, each type has its specific application occasions.

3. Advantages

Excellent mechanical properties: C-shaped steel has high strength, high hardness, good toughness, and can withstand large weight and pressure.

Simple structure and convenient installation: the cross-sectional shape is simple, the structure is stable, and the length can be cut and processed as needed, which is convenient for processing and assembly at the construction site.

Strong durability: after hot-dip galvanizing treatment, it has strong corrosion resistance and oxidation resistance, and long service life.

Wide range of application: widely used in construction, machinery manufacturing, petrochemical, electric power, aerospace and other fields.

4. Application field

Construction field: used to make steel structure frames, roof trusses, wall frames, beams, columns and other components, and can also be used to make decorative components such as door and window frames, curtain wall frames, partitions, etc.

Machinery manufacturing field: used to make machine tool beds, workbenches, shelves, conveyor lines and other components.

Petrochemical industry: used to make storage tanks, pipelines, brackets and other components.

Power industry: used to make transmission towers, poles, cable trays and other components.

Aerospace industry: used to make aircraft structural parts, rocket engine shells and other components.

5. Processing process

The processing process of C-shaped steel mainly includes unloading, leveling, forming, shaping, straightening, length measurement, punching of tie rod round holes, punching of elliptical connection holes, forming and cutting. With the advancement of technology, fully automatic C-shaped steel forming equipment and fully automatic CZ-shaped steel integrated machine came into being, greatly improving production efficiency and product quality.
