ASTM A992 S355JR Q355 Wide Flange H Beams For Structure And Construction
Main Types
(1)Wide Flange Beams (W-Beams):
Flanges are wider than the web, providing better load distribution.
Commonly used in building frames and bridges.
(2)Junior Beams (S-Beams):
Narrower flanges compared to W-beams.
Used in lighter structural applications.
(3)Pile Beams (HP-Beams):
Flanges and web have similar thickness, making them ideal for deep foundation piles.
