W14x145 FAQ
What does W14x145 mean?
W means wide flange. The first number (14) is the nominal depth in inches, and the second number (145) is the weight in pounds per foot. The actual depth of W14x145 is 14.8 in. How to read steel beam sizes.
How much does a W14x145 beam weigh?
W14x145 weighs 145 lb per foot (216 kg per meter). A 20 ft beam weighs about 2,900 lb. Use the calculator above for any length.
What is the metric equivalent of W14x145?
The metric (SI) designation is W360x216: 376 mm deep with a 394 mm flange and 216 kg/m.
How far can a W14x145 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.
