Common Specifications of Imported Channel Steel
Imported channel steel is widely used in construction, manufacturing, and infrastructure projects due to its high strength and durability. Buyers often need
to understand the standard specifications to ensure compatibility with their requirements. Below are the common specifications of imported channel steel.
1. Dimensions & Weight
Channel steel is categorized by its height (h), flange width (b), web thickness (d), and flange thickness (t). Common specifications include:
| Model (Metric) | Height (h, mm) | Flange Width (b, mm) | Web Thickness (d, mm) | Flange Thickness (t, mm) | Theoretical Weight (kg/m) |
|---|---|---|---|---|---|
| C80×40×15×2.5 | 80 | 40 | 15 | 2.5 | 6.70 |
| C100×50×20×3.0 | 100 | 50 | 20 | 3.0 | 9.30 |
| C120×60×25×3.5 | 120 | 60 | 25 | 3.5 | 12.10 |
| C150×75×30×4.0 | 150 | 75 | 30 | 4.0 | 16.20 |
(Note: Dimensions may vary slightly depending on the manufacturing standard.)
