HEA450 wf steel beam
Due to its narrow flange width, it is suitable for application scenarios with limited space requirements.
Commonly used in the manufacture of various mechanical parts and components, such as crane arms, excavator buckets, and other occasions that require efficient use of space.

HEB450 wide flange beam
With a wider flange width, it provides a larger cross-sectional area and a higher section modulus, suitable for occasions with large bending moments and shear forces.
Widely used in large building structures and bridge projects as beams, columns and other key supporting components, especially in structures that require higher load-bearing capacity and stability.
