W14x43 FAQ
What does W14x43 mean?
W means wide flange. The first number (14) is the nominal depth in inches, and the second number (43) is the weight in pounds per foot. The actual depth of W14x43 is 13.7 in. How to read steel beam sizes.
How much does a W14x43 beam weigh?
W14x43 weighs 43 lb per foot (64 kg per meter). A 20 ft beam weighs about 860 lb. Use the calculator above for any length.
What is the metric equivalent of W14x43?
The metric (SI) designation is W360x64: 348 mm deep with a 203 mm flange and 64 kg/m.
How far can a W14x43 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.
