Expanded Screen Strength

[dkgpune]

Dear All,

Here is the scenario:

There is an expanded metal screen (steel G550) with diamond shaped openings. An example is at

http://www.dexmet.com/Expanded-Metals.html

I know the basic dimensions of such as screen LWD, SWD, SWO, LWO, thickness etc..

The question is if a given expanded screen can work for 1.2kN/sq.m pressure?

Effective span = 1.25 m, height is 1 m.

How to find this screen strength? Any formula, reference, calculator shall be very helpful.

Thanks,
