Introduction
C Shape Steel Beam is a high-strength steel profile with a distinctive C-shaped cross-section, formed by cold-bending hot-rolled plates. Designed for lightweight yet durable structural applications, it balances material efficiency with load-bearing capacity and is widely used in construction, mechanical manufacturing, and other fields.

Features
- Unique C-Shaped Design
Improves load distribution, torsional resistance, and structural efficiency.
- High Cost-Efficiency
Its hollow structure reduces raw material consumption by 30%-50% compared to traditional steel profiles, lowering procurement and transportation costs (lighter weight means fewer shipping fees).
- Easy Installation
Supporting custom cutting (length 1-12 m) and hole drilling allow for fast on-site assembly (using bolts or rivets), reducing construction time by 20%-30% compared to custom-welded structures.
- Corrosion Resistance
The hot-dip galvanized layer resists rain, humidity, and industrial fumes, with an urban service life of over 20 years.
- Good Processability
Made via cold rolling or hot rolling (from hot-rolled steel coils), it retains excellent ductility and is easy to weld, bend (with tensile strength 375-550 MPa), or connect with other structural parts (e.g., U-steel, flat steel) without cracking.
Technical Specifications

Material |
Mostly carbon steel (such as Q235B, Q345B) or stainless steel (such as 316L, 2507). |
|
Composition |
Carbon steel has a relatively low carbon content (for example, the carbon content of Q235B is ≤0.22%), while stainless steel contains alloy elements such as chromium and nickel (for instance, 316L contains 16-18% chromium and 10-14% nickel). |

FAQ
Q: How is the C-shaped steel formed?
A: The production process of C-shaped steel mainly consists of three stages: material preparation, cold-bending forming, and processing equipment. The first stage is material preparation. The main raw material for C-shaped steel is cold-rolled coil, which needs to go through processes such as uncoiling, leveling, and cutting for processing.
Cold-formed steel: The C-shaped steel forming machine automatically completes the processes of feeding, leveling, forming, setting, straightening, measuring length, punching, and cutting.
Surface treatment: Including electro-galvanizing, hot-dip galvanizing (zinc coating 120-275 g/㎡, service life over 20 years), or epoxy spraying.
Processing technology services: Support for bending, punching, stamping, and other deep processing.
