C-Shaped Channel Steel

C-shaped steel is a cold-formed, thin-walled steel section with a "C" cross-section. It is formed by cold-rolling steel sheets into a fixed cross-section. It features lightweight construction and stable mechanical properties. It is widely used in load-bearing or supporting structures in construction, machinery, transportation, and other fields, offering a highly efficient alternative to traditional angle steel and channel steel.

II. Material

The core material of C-shaped steel is low-carbon steel (such as Q235 and Q345). In some applications, high-strength low-alloy steel may be used depending on strength requirements.

Q235 steel: Offers high cost-effectiveness, excellent plasticity and toughness, and is suitable for general load-bearing structures with light loads (such as purlins and brackets in lightweight factory buildings).

Q345 steel: A high-strength, low-alloy structural steel with higher yield strength, excellent impact resistance, and excellent weldability. It is suitable for applications with heavy loads and demanding structural stability (such as load-bearing frames for large buildings and load-bearing machinery brackets). In addition, to enhance corrosion resistance (e.g., in humid environments and outdoor applications), some C-shaped steel sections undergo surface treatments such as galvanizing (cold-dip galvanizing or hot-dip galvanizing) and anti-corrosion coatings to extend their service life.

III. Detailed Parameters and Structural Features

Cross-sectional Dimensions:

Common heights (waist heights) range from 50mm to 300mm, thicknesses from 1.5mm to 5mm, and flange widths (the upper and lower edges of the "C" section) from 20mm to 100mm. Specific dimensions can be customized based on engineering drawings to meet varying load-bearing requirements.

Process Details:

Using a cold-formed process, cross-sectional dimensions are highly accurate (error controllable within ±0.5mm), resulting in a smooth, burr-free surface. The flanges and web (the vertical edges of the "C") maintain perfect perpendicularity, ensuring a tight fit during connection.

Connection Design:

Some C-shaped steel sections have pre-reserved bolt holes or slots for quick connection to other components (such as purlins, braces, and supports), reducing on-site processing steps and improving construction efficiency. Length Specifications:

Common lengths range from 6m to 12m. Custom lengths can be produced based on transportation and construction requirements, eliminating material waste.

IV. Advantages

High Strength and Excellent Load-Bearing Performance:

The cold-bending process refines the steel's internal grain size, improving its mechanical properties. At the same weight, C-shaped steel exhibits superior bending and shear strength compared to traditional angles and channels. This allows it to bear greater loads with less weight, achieving "lightweight load-bearing."

High Precision and Easy Installation:

The cross-sectional dimensional tolerances are minimal, the surface is smooth, and prefabricated connection holes are available. No secondary cutting or grinding is required during on-site installation; it can be directly assembled using bolts and slots, significantly shortening the construction cycle and reducing labor costs.

Material Savings and High Cost-Effectiveness:

Cold-bending eliminates cutting waste, achieving a material utilization rate of over 95%. Compared to traditional profiles, steel consumption can be reduced by 30%-50% for the same load-bearing requirements, lowering overall material costs.
