W14x90 FAQ
What does W14x90 mean?
W means wide flange. The first number (14) is the nominal depth in inches, and the second number (90) is the weight in pounds per foot. The actual depth of W14x90 is 14 in. How to read steel beam sizes.
How much does a W14x90 beam weigh?
W14x90 weighs 90 lb per foot (134 kg per meter). A 20 ft beam weighs about 1,800 lb. Use the calculator above for any length.
What is the metric equivalent of W14x90?
The metric (SI) designation is W360x134: 356 mm deep with a 368 mm flange and 134 kg/m.
How far can a W14x90 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.
