W8x35 FAQ
What does W8x35 mean?
W means wide flange. The first number (8) is the nominal depth in inches, and the second number (35) is the weight in pounds per foot. The actual depth of W8x35 is 8.12 in. How to read steel beam sizes.
How much does a W8x35 beam weigh?
W8x35 weighs 35 lb per foot (52 kg per meter). A 20 ft beam weighs about 700 lb. Use the calculator above for any length.
What is the metric equivalent of W8x35?
The metric (SI) designation is W200x52: 206 mm deep with a 204 mm flange and 52 kg/m.
How far can a W8x35 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.
