Looking for aluminum trim

So I've got a customer that want an aluminum trim around his mural. I hate the idea, but he is paying for. I've tried to find a good solution and the only model I've found is a technical drawing. But no information on where I could get them.

If possible, I would like to have a source in Canada (Montreal area). I'm open to all suggestions also.

Thanks.

 

I've found some pictures on the net of how it should look like.

 

Yes. I've even called them to be sure. They only have trims like J-shaped or U-shaped for thick material.

 

What is the mural made of= general formulation 226 (6mil vinyl)
What's the finished size of the mural= 241in wide X 95in high
What size trim do you desire= something around 2in X 1/4 thick, anodized aluminum color
How is the mural being fastened to the wall= the mural is stick on the wall (vinyl)

 

no luck. They said they can not help me with this.
