W14x26 FAQ
What does W14x26 mean?
W means wide flange. The first number (14) is the nominal depth in inches, and the second number (26) is the weight in pounds per foot. The actual depth of W14x26 is 13.9 in. How to read steel beam sizes.
How much does a W14x26 beam weigh?
W14x26 weighs 26 lb per foot (39 kg per meter). A 20 ft beam weighs about 520 lb. Use the calculator above for any length.
What is the metric equivalent of W14x26?
The metric (SI) designation is W360x39: 353 mm deep with a 128 mm flange and 39 kg/m.
How far can a W14x26 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.
