W10x68 FAQ
What does W10x68 mean?
W means wide flange. The first number (10) is the nominal depth in inches, and the second number (68) is the weight in pounds per foot. The actual depth of W10x68 is 10.4 in. How to read steel beam sizes.
How much does a W10x68 beam weigh?
W10x68 weighs 68 lb per foot (101 kg per meter). A 20 ft beam weighs about 1,360 lb. Use the calculator above for any length.
What is the metric equivalent of W10x68?
The metric (SI) designation is W250x101: 264 mm deep with a 257 mm flange and 101 kg/m.
How far can a W10x68 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.
