W12x35 Beam Specifications

W12x35 is a rolled structural beam with wide flanges that is used in construction and other applications.

W12x35 Beam Size and Dimensions

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

Depth12.5 in
Width6.56 in
Area10.3 in2
Weight35 lb/ft

W12x35 Profile

W12x35 beam specifications

The depth of W12x35 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.

W12x35 Weight

Wide flange beams are designated by their depth x weight. The W12x35 designation indicates that the beam weighs 35 pounds per foot. A 10-foot section of W12x35 would weigh 350 pounds and a 50-foot section of W12x35 would weigh 1,750 pounds.

W12x35 Conversion to Metric

The metric equivalent to W12x35 is W310x52. This metric beam has the following specifications:

Depth317 mm
Width167 mm
Area6650 mm2
Weight52 kg/m
Web Thickness7.6 mm
Flange Thickness13.2 mm

W12x35 Section Properties

W12x35 Area Moment of Inertia

The area moment of inertia (or second moment area) for a W12x35 beam about the x-axis (perpendicular to the flange) can be calculated from the equation below:

W12x35 area moment of inertia

The area moment of inertia of the W12x35 profile about the x-axis is approximately 283 in4.

W12x35 Section Modulus

The elastic section modulus for a W12x35 beam about the X-axis is calculated from the following equation:

W12x35 Section Modulus

The elastic section modulus for the W12x35 profile about the X-axis is approximately 45 in3.

W12x35 Properties

The properties of W12x35 beams are specified by ASTM A6 “Standard Specifications for Rolled Structural Steel Bars, Plates, Shapes and Sheet Piling
