Mechanical Properties

U channel steel and C channel steel each have their own advantages in mechanical properties. The former can effectively disperse stress when subjected to vertical or lateral loads and is widely used in application fields such as Bridges and high-rise buildings. The latter achieves weight reduction while ensuring strength by optimizing the cross-sectional design, and has good torsional resistance.

Yield Strength

235-355 MPa

Tensile Strength

360-630 MPa

Melting Point

carbon steel: 1420-1530℃
galvanized channel steel：419℃

Hardness

120-160 HBW

Steel Channel Features

Unique section shape

Channel steel section is C-shaped or U-shaped groove structure, the two sides of the flange extend outward, the middle is the web. This design results in excellent load-bearing and flexural performance, especially for lateral loads.

Excellent mechanical properties

Using Q235, Q355 and other carbon or low alloy steel rolling, tensile strength up to 420-540MPa, yield strength ≥235MPa, suitable for heavy structural support.

Variety of specifications

Specifications cover 5# to 40# (waist height 50mm-400mm), thickness 5mm-100mm, length 6-6.5 meters, support customized production to meet different engineering needs.

Good machining performance

Steel metal channel can be processed by cutting, welding, drilling and other ways to adapt to complex structure assembly. In addition, surface galvanization, spray paint and other anti-corrosion treatments can extend its service life, suitable for wet or corrosive environment.

Why Choose IBC Group

IBC Group is a professional steel metal channel supplier, capable of offering a wide range of specifications, high-quality steel profiles, as well as meticulous pre-sale and after-sale services to our customers.

Uncompromising Metallurgical Quality & Certification Precision

Specific Quality Metrics:
1. Chemical Consistency:
Channels comply with ASTM A36/A572 Gr. 50, EN 10025 S355JR, and JIS G3101 SS400.
Carbon content controlled to ±0.02% of target (e.g., A36: max 0.26% C, actual 0.24–0.25%).
Phosphorus/sulfur impurities capped at ≤0.025% (vs. standard 0.04%), reducing brittleness.
2. Mechanical Superiority:
Yield strength variance <±15 MPa (e.g., S355JR guaranteed 355–375 MPa vs. standard 355 MPa min).
Charpy V-notch impact tested at -20°C (exceeds standard 0°C for S355JR), absorbing ≥40 Joules.
3. Certification Rigor:
Mill Test Certificates (MTCs) include heat number traceability, third-party lab validation (SGS/BV), and full-dimension inspection reports.
