W18x119 FAQ

What does W18x119 mean?

W means wide flange. The first number (18) is the nominal depth in inches, and the second number (119) is the weight in pounds per foot. The actual depth of W18x119 is 19 in. How to read steel beam sizes.

How much does a W18x119 beam weigh?

W18x119 weighs 119 lb per foot (177 kg per meter). A 20 ft beam weighs about 2,380 lb. Use the calculator above for any length.

What is the metric equivalent of W18x119?

The metric (SI) designation is W460x177: 483 mm deep with a 287 mm flange and 177 kg/m.

How far can a W18x119 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.
