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:
