New Steel Channel Products Enhance Construction and Manufacturing Efficiency

Steel channels, a type of Long Steel with a U-shaped cross-section, are widely used in construction, machinery, and vehicle manufacturing due to their excellent welding, riveting, and mechanical properties. These carbon structural steel products, with a carbon content not exceeding 0.25%, are delivered in hot-rolled or normalized conditions, offering superior performance for industrial applications.

Classification and Specifications

Steel channels are categorized into standard and lightweight types. Hot-rolled standard channels range from #5 to #40, while lightweight channels feature narrower flanges and thinner webs, reducing weight without compromising strength. Channels are further divided into four shapes:

• Cold-formed equal-leg channels

• Cold-formed unequal-leg channels

• Cold-formed inwardly flanged channels

• Cold-formed outwardly flanged channels

Specifications are defined by height (h), flange width (b), and web thickness (d). Domestic sizes span #5–#40 (5–40 cm in height), with #18–#40 classified as large-sized and #5–#16 as medium-sized.

Applications and Advantages

Steel channels are essential in:
✔ Construction (buildings, bridges, highways)
✔ Industrial machinery (equipment frames, platforms)
✔ Transportation (vehicle manufacturing)
✔ Energy-saving structures (30–40% material reduction vs. I-Beams)

Their optimized design ensures even stress distribution, high load-bearing capacity, and cost-effective material use, making them a sustainable choice for modern engineering.

Global Trade and Standards

Imported channels adhere to international size and composition standards. Orders typically specify dimensions and steel grade (carbon or low-alloy). Delivery lengths vary:

• Domestic: 5–12m, 5–19m, or 6–19m

• Imported: 6–15m

With advancing manufacturing techniques, steel channels continue to drive innovation in infrastructure and industrial sectors, combining durability with eco-friendly benefits.
