W12x106 W12x120 Wide Flange H Beam Section
W12x106 h-shaped iron beam: "W" represents wide flange H-shaped steel; "12" represents the nominal height of the steel is 12 inches (about 304.8mm); "106" represents the weight of the steel per foot length is 106 pounds (about 48.1kg/m).
W12x120 h-section steel beam: "W" represents wide flange H-shaped steel; "12" represents the nominal height is 12 inches (about 304.8mm); "120" represents the weight of the steel per foot length is 120 pounds (about 54.4kg/m).
W12x106 h-shaped beam: flange width is about 12.2 inches (about 309.9mm), flange thickness is about 0.68 inches (about 17.3mm), web thickness is about 0.42 inches (about 10.7mm), and cross-sectional area is about 31.1 square inches (about 199.9cm²).
Moment of inertia (Ix) is about 2910 inches⁴ (about 1210.7cm⁴), moment of inertia (Iy) is about 541 inches⁴ (about 225.3cm⁴).
Section modulus (Sx) is about 485 inches³ (about 7947.6cm³), and section modulus (Sy) is about 88.7 inches³ (about 1453.5cm³).
W12x120 h beam steel structure: flange width is about 12.3 inches (about 312.4mm), flange thickness is about 0.79 inches (about 20.1mm), web thickness is about 0.46 inches (about 11.7mm), and cross-sectional area is about 35.3 square inches (about 227.7cm²).
Moment of inertia (Ix) is about 3400 inches⁴ (about 1414.2cm⁴), moment of inertia (Iy) is about 633 inches⁴ (about 263.5cm⁴).
Section modulus (Sx) is about 567 inches³ (about 9290.4cm³), and section modulus (Sy) is about 102 inches³ (about 1671.6cm³).
These two types of steel are usually made of high-strength structural steel and have good strength and toughness.
The yield strength is generally not less than 50ksi (about 345MPa), and the tensile strength is about 65-80ksi (about 448-552MPa); it has a high elastic modulus of about 29000ksi (about 200GPa), and can maintain good elastic deformation ability when bearing load.
