## W12x14 Beam Size and Dimensions

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

Depth | 11.91 in |

Width | 3.97 in |

Area | 4.2 in^{2 } |

Weight | 14 lb/ft |

Web Thickness | 0.2 in |

Flange Thickness | 0.23 in |

Area Moment of Inertia | 86.1 in^{4} |

Elastic Section Modulus | 14 in^{3} |

## W12x14 Profile

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:

Depth | 303 mm |

Width | 101 mm |

Area | 2680 mm^{2} |

Weight | 21 kg/m |

Web Thickness | 5.1 mm |

Flange Thickness | 5.7 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:

The area moment of inertia of the W12x14 profile about the x-axis is approximately 86.1 in^{4}.

### W12x14 Section Modulus

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

The elastic section modulus for the W12x14 profile about the X-axis is approximately 14 in^{3}.

## W12x14 Properties

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