W16x89 FAQ
What does W16x89 mean?
W means wide flange. The first number (16) is the nominal depth in inches, and the second number (89) is the weight in pounds per foot. The actual depth of W16x89 is 16.8 in. How to read steel beam sizes.
How much does a W16x89 beam weigh?
W16x89 weighs 89 lb per foot (132 kg per meter). A 20 ft beam weighs about 1,780 lb. Use the calculator above for any length.
What is the metric equivalent of W16x89?
The metric (SI) designation is W410x132: 427 mm deep with a 264 mm flange and 132 kg/m.
How far can a W16x89 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.
