W14x82 FAQ
What does W14x82 mean?
W means wide flange. The first number (14) is the nominal depth in inches, and the second number (82) is the weight in pounds per foot. The actual depth of W14x82 is 14.3 in. How to read steel beam sizes.
How much does a W14x82 beam weigh?
W14x82 weighs 82 lb per foot (122 kg per meter). A 20 ft beam weighs about 1,640 lb. Use the calculator above for any length.
What is the metric equivalent of W14x82?
The metric (SI) designation is W360x122: 363 mm deep with a 257 mm flange and 122 kg/m.
How far can a W14x82 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.
