Metal Wall Panels

I’m not sure of the correct name but as the above subject refers I am in need of some. Not the normal mabati,these ones are thicker and stiffer,preferably not corrugated.
If you do know where I can get some I would appreciate. Price guidance would also be welcome.
Regards.

Umeamua kujenga nyumba ya mabati?

Si uweke drywall budah!

dry wall won’t survive the weather elements, this is for outside use,not internal partitions.

ingia pale jua kali ang get refferals,ama ununue kutoka kwao though itakua expe kiasi,wako na zile za kumake sanduku ya boarding,alafu zile za panels za gari, and the thick ones za 3.5mm-5mm

This might be what am looking for.
