The reason why you cannot post a "live" link is that it requires 5 posts made.
Regarding the metal border - it requires very precise work in close zoom-in.
For the start I'd use the real rivet (or other metal element) photos to see how the light reflects on the surface and edges. After scaling down a rivet photo, I would work on its sharpness and strengthen the light effects.
As for the metal pattern - try to find a photo of a metal surface (http://www.cgtextures.com/ -> Metal) and use it as your background. Adding light and dark lines in Multiply or Screen blending mode will let you create this 3-dimensional effect.
