Bhaskar,

It is not simply answered question, the variables are:

Gauge thickness of steel in question.

type of steel-high carbon, low carbon, stainless etc.

Total length of steel to be used for desired application.

The steel manufacturer will have standard weight tables for the various products per foot of material or per meter etc. it offers in its catalog of products and if they do not do not buy anything from them!!!!!!

You may just want to buy your own thick flat stock a certain width and weld the pieces together to make square tube for your screens. ■
