W14x109 FAQ
What does W14x109 mean?
W means wide flange. The first number (14) is the nominal depth in inches, and the second number (109) is the weight in pounds per foot. The actual depth of W14x109 is 14.3 in. How to read steel beam sizes.
How much does a W14x109 beam weigh?
W14x109 weighs 109 lb per foot (162 kg per meter). A 20 ft beam weighs about 2,180 lb. Use the calculator above for any length.
What is the metric equivalent of W14x109?
The metric (SI) designation is W360x162: 363 mm deep with a 371 mm flange and 162 kg/m.
How far can a W14x109 beam span?
Span depends on the load, support conditions, deflection limits and local building code, so it cannot be read from a size table. A licensed structural engineer must size any beam that carries a load.
