How do I work out the load bearing capacity of a steel flat beam (30x3 mm x 2m)?

Posted: 2/17/2013 9:09:50 PM


Please be kind as I have done pretty close to zero work in engineering, maths and physics. Basically, I want to know how to calculate the load bearing capacity of a steel flat beam of certain dimensions (lets say 30x3 mm x 2m in length). I want to make a bedframe (similar to the urano floating bed) and need to know what dimensions of steel to order.


If the urano bed was constructed of a solid steel plate it would be unbelievably heavy. It's likely it's constructed of a series of thin C-shaped or tubular steel elements, and covered with plywood or plastic veneer. I'm don't really understand what you're trying to describe with the dimensions you provide. Are you talking about a flat steel plate of 3mm thickness?

In an case a person couldn't even begin to try to calculate the load-bearing requirements without knowing *exactly* how the bed is constructed.
