Скачать или смотреть American Wide Flange Beam W30x108 W30x116

W30x108 steel and W30x116 h section steel are wide-flange H-section steels in the American Institute of Steel Construction (AISC) standard: W stands for "Wide Flange"; 30 stands for the nominal depth of the steel in inches, which is approximately 30 inches (762 mm); 108 and 116 stand for the weight of the steel in pounds per foot (lb/ft), i.e. W30x108 is 108 lb/ft and W30x116 is 116 lb/ft.
W30x116 is heavier than W30x108, mainly because the thickness of the flange and web is increased, resulting in a larger cross-sectional area and stronger load-bearing capacity; the moment of inertia and section modulus of W30x116 h section beam are larger, and the bending resistance and stiffness are better than W30x108 steel h column, which is suitable for higher load scenarios.
