W12x14 W12x16 W12x19 A36/A572GR50/A992 h beam steel structure
The W12 series H-shaped steel increases the load-bearing capacity by increasing the thickness of the web and flange. The W12×19 has the best performance, while the W12×14 focuses on lightweight economy. The W12×14 (20.8kg/m) of the A36 h beam steel structure is suitable for light structures, and the W12×19 (28.3kg/m) of the A992 h shaped iron beam has better shear resistance and is very suitable for heavy load scenarios.
Web and flange thickness: W12×19 has the thickest web (7.7mm) and the thickest flange (11.1mm), and has the strongest shear and bending resistance; W12×14 has thinner web and flange (6.6mm/8.9mm) and is lighter.
Section height and flange width: W12×19 has the largest height (313mm) and the widest flange (133mm), and its stability is better than W12×14 and W12×16.
