The depth of W16x26 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.
W16x26 Weight
Wide flange beams are designated by their depth x weight. The W16x26 designation indicates that the beam weighs 26 pounds per foot. A 10-foot section of W16x26 would weigh 260 pounds and a 50-foot section of W16x26 would weigh 1,300 pounds.
W16x26 Conversion to Metric
The metric equivalent to W16x26 is W410x38.8. This metric beam has the following specifications:
| Depth | 399 mm |
| Width | 140 mm |
| Area | 4950 mm2 |
| Weight | 38.8 kg/m |
| Web Thickness | 6.4 mm |
| Flange Thickness | 8.8 mm |
W16x26 Section Properties
W16x26 Area Moment of Inertia
The area moment of inertia (or second moment area) for a W16x26 beam about the x-axis (perpendicular to the flange) can be calculated from the equation below:
The area moment of inertia of the W16x26 profile about the x-axis is approximately 294 in4.
W16x26 Section Modulus
The elastic section modulus for a W16x26 beam about the X-axis is calculated from the following equation:
The elastic section modulus for the W16x26 profile about the X-axis is approximately 37 in3.
W16x26 Properties
The properties of W16x26 beams are specified by ASTM A6 “Standard Specifications for Rolled Structural Steel Bars, Plates, Shapes and Sheet Piling”
