Hi @alijalil,

@alijalil

So what I wanted to ask was that is the " I beam of 14kg/m " considered lightest commercial I beam throughout the world or just for particular countries?

I’m only familiar with the sizes made in Australia. I presume that other sizes are made around the world.

@alijalil

Secondly as I told you that the fabricators in pakistan make the I beam according to their own sizes as I have shown you that the thickness of 2.5 mm has been used. So is this a bad practice? I mean would it have any negative side effects?

I-beam dimensions are optimised to have a high strength-to-weight ratio. If you specify your own I-beam dimensions you may find that it’s performance is not optimal. For example. If the web is made too thin it may fail in buckling before it reaches it tensile capacity (as demonstrated in this video https://youtu.be/cM1mVXSFnq0)
