The depth of W6x15 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.

W6x15 Weight

Wide flange beams are designated by their depth x weight. The W6x15 designation indicates that the beam weighs 15 pounds per foot. A 10-foot section of W6x15 would weigh 150 pounds and a 50-foot section of W6x15 would weigh 750 pounds.

W6x15 Conversion to Metric

The metric equivalent to W6x15 is W150x22.5. This metric beam has the following specifications:

W6x15 Area Moment of Inertia

The area moment of inertia (or second moment area) for a W6x15 beam about the x-axis (perpendicular to the flange) can be calculated from the equation below:

The area moment of inertia of the W6x15 profile about the x-axis is approximately 28.7 in⁴.

W6x15 Section Modulus

The elastic section modulus for a W6x15 beam about the X-axis is calculated from the following equation:

The elastic section modulus for the W6x15 profile about the X-axis is approximately 10 in³.
