W6x15 Beam Specifications

W6x15 is a rolled structural beam with wide flanges that is used in construction and other applications.

W6x15 Beam Size and Dimensions

The dimensions and specifications of this structural steel beam are below:

Depth	5.99 in
Width	5.99 in
Area	4.4 in2
Weight	15 lb/ft
Web Thickness	0.23 in
Flange Thickness	0.26 in
Area Moment of Inertia	28.7 in4
Elastic Section Modulus	10 in3

W6x15 Profile

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:

Depth	152 mm
Width	152 mm
Area	2860 mm2
Weight	22.5 kg/m
Web Thickness	5.8 mm
Flange Thickness	6.6 mm

W6x15 Section Properties

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.

W6x15 Properties

The properties of W6x15 beams are specified by ASTM A6 “Standard Specifications for Rolled Structural Steel Bars, Plates, Shapes and Sheet Piling”
