W14x30 FAQ
What does W14x30 mean?
W means wide flange. The first number (14) is the nominal depth in inches, and the second number (30) is the weight in pounds per foot. The actual depth of W14x30 is 13.8 in. How to read steel beam sizes.
How much does a W14x30 beam weigh?
W14x30 weighs 30 lb per foot (44 kg per meter). A 20 ft beam weighs about 600 lb. Use the calculator above for any length.
What is the metric equivalent of W14x30?
The metric (SI) designation is W360x44: 351 mm deep with a 171 mm flange and 44 kg/m.
How far can a W14x30 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.
