Well thats a relief.....We had the same problem....
We got our alum curtainwall from China once and the tolerenceces on that where out a mile not to mention the metal was bent scratched twistedand they probably stuck us with lead paint to boot.
But mix that alum, with precise CNC machinery, and the holes where out by miles just because the metal was that bad..Not to mention we had a tone of damaged material,
and it took weeks to get it replaced.
By the time that job was done and once we figured in all the overtime, and the headaches of communcating with them
it wasn't worth it.
So we went back to Kawneer.Nice straight clean material
and quick delivery..
