A new invention but no completed

[Thinkingmachine]

I am doing business with a Japanese partner to help japanese people to remain safe during earthquakes which require building a small metallic shelter in their homes, it should stand the destruction during an earthquake.
My question, what metal is the right choice?
It must have unique cohesive properties
1. Strong to stand even if the roof fall apart
2. Light
3. Affordable
Kindly help me with the latest tech in the market as our project is meeting a deadline

This is way too big/serious of a project for PF to be capable of providing the help for you that you need. Asking for and utilizing help from here is dangerous. You need a qualified engineering team working on the project, employed by your/their company.
