Aluminum Sheet:
It scratches easily so giving it a brushed texture can hide imperfections. As a sheet it is not very structural but when bend into curved shapes it turns incredibly strong.
Ruber Mat & Wire:
Rubermat can be a recycled material and has soft properties. It is strong but not sutrctural.
Threading wire through the mat makes it structural and bendable. Adding resin to it hardens it, but once it hardens it can not be bend anymore.
