I'm looking into cheaply making a Dawrven statue/other pieces of art, using various armor and or scrap metal. Is there a way to make these items completely static, where there is no physics applied to them?

I created a cool piece of art using scrap metal, but if you shoot it with an arrow or hit it by any means, all the pieces go flying. I know not to havock settle them so I'm wondering what other step I need to make, to make things a part of the non interactive scenery.
