W24x55 Profile

W24x55 beam specifications

The depth of W24x55 beams may vary by 1/8” above and below the nominal value.

The flange width may vary by 1/4” above nominal and 3/16” below nominal. Flanges may be out of square by as much as 5/16”.

The distance from the center of the web to the center of the profile may be no greater than 3/16”.

The radii of fillets and toes for W-beams are not specified. Instead, these dimensions are left up to individual manufacturers.

W24x55 Weight

Wide flange beams are designated by their depth x weight. The W24x55 designation indicates that the beam weighs 55 pounds per foot. A 10-foot section of W24x55 would weigh 550 pounds and a 50-foot section of W24x55 would weigh 2,750 pounds.

W24x55 Conversion to Metric

The metric equivalent to W24x55 is W610x82. This metric beam has the following specifications:

Depth599 mm
Width178 mm
Area10500 mm2
Weight82 kg/m
Web Thickness10 mm
Flange Thickness12.8 mm

W24x55 Section Properties

W24x55 Area Moment of Inertia

The area moment of inertia (or second moment area) for a W24x55 beam about the x-axis (perpendicular to the flange) can be calculated from the equation below:

W24x55 area moment of inertia

The area moment of inertia of the W24x55 profile about the x-axis is approximately 1324 in4.

W24x55 Section Modulus

The elastic section modulus for a W24x55 beam about the X-axis is calculated from the following equation:

W24x55 Section Modulus

The elastic section modulus for the W24x55 profile about the X-axis is approximately 112 in3.
