W33x263 h shaped steel
Model meaning: W represents wide flange H-shaped steel, 33 is the nominal height (inches), and 263 represents the unit weight of approximately 263 pounds per foot (390kg/m).
Sectional dimensions (reference similar W33 series):
Height (H): 838mm (33 inches)
Flange width (B): ~400mm
Web thickness (t1): ~26mm
Flange thickness (t2): ~43mm
Weight per meter: about 363kg/m (subject to actual production data).
W33x291 h beam structure
The model naming logic is consistent with W33x263, 291 means the unit weight is about 291 pounds/foot (432kg/m).
Sectional dimensions: slightly thicker than W33x263, suitable for higher load-bearing requirements.
Weight per meter: about 432kg/m (need to be combined with supplier technical parameters).
Application of W33x263 W33x291h type beam
Wind power engineering: used for key structures such as towers and load-bearing brackets.
Heavy construction: support beams for bridges, high-rise buildings, and industrial plants.
Machinery manufacturing: large equipment bases, port crane rails.
Marine engineering: offshore platforms, ship reinforcement structures.
W33x263 W33x291 structural h beam production and standards
American standard: ASTM A36/A36M19
Other optional materials: A572 Gr50 (higher strength), A992 (for construction).
