W12x14 Beam Specifications

W12x14 is a rolled structural beam with wide flanges that is used in construction and other applications.

W12x14 Beam Size and Dimensions

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

Depth11.91 in
Width3.97 in
Area4.2 in2
Weight14 lb/ft

W12x14 Profile

W12x14 beam specifications

The depth of W12x14 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.

W12x14 Weight

Wide flange beams are designated by their depth x weight. The W12x14 designation indicates that the beam weighs 14 pounds per foot. A 10-foot section of W12x14 would weigh 140 pounds and a 50-foot section of W12x14 would weigh 700 pounds.

W12x14 Conversion to Metric

The metric equivalent to W12x14 is W310x21.0. This metric beam has the following specifications:

Depth303 mm
Width101 mm
Area2680 mm2
Weight21 kg/m
Web Thickness5.1 mm
Flange Thickness5.7 mm

W12x14 Section Properties

W12x14 Area Moment of Inertia

The area moment of inertia (or second moment area) for a W12x14 beam about the x-axis (perpendicular to the flange) can be calculated from the equation below:

W12x14 area moment of inertia

The area moment of inertia of the W12x14 profile about the x-axis is approximately 86.1 in4.

W12x14 Section Modulus

The elastic section modulus for a W12x14 beam about the X-axis is calculated from the following equation:

W12x14 Section Modulus

The elastic section modulus for the W12x14 profile about the X-axis is approximately 14 in3.

W12x14 Properties

The properties of W12x14 beams are specified by ASTM A6 “Standard Specifications for Rolled Structural Steel Bars, Plates, Shapes and Sheet Piling
