Quick steel question

[Hereonce]

When you are told that you are using 350W steel, what does the 350 represent? What does the W represent?

Its a study question, but just wanted to run it by you guys so i know i am correct.

W represents that the steel is weldable

350 describes the nominal depth(feel like i am wrong on this one?!)



Thanks in advance.

350 is Fy in MPa. I am not looking now for the W meaning in the spec since I don't practice in Canada, but I may have the info somewhere and say if no other explains before.

W means it's weldable...

Grade 350W is weldable steel with a yield stress of 350 MPa.
A W350x## section is a wide flange beam with a depth of 350 mm.

Thanks Trundle for making that more clear.
