Differences Between H-Beam, C-Channel, and Z-Channel Steel

1. H-Beam Steel

Shaped like the letter “H,” it provides excellent load-bearing capacity and is commonly used for main factory frames, bridges, and high-rise structures.

2. C-Channel Steel

Lightweight and shaped like the letter “C,” it is often used for roof purlins and wall beams. It saves material while offering sufficient strength for secondary structures.

3. Z-Channel Steel

Shaped like the letter “Z,” it has higher strength than C-channel steel and is suitable for large-span roofs and high-load purlin systems.

4. Selection Tips

• Main load-bearing structure: H-beam steel
• Roof and wall purlins: C-channel steel
• Large-span buildings: Z-channel steel
