FAQ

Q: Can you do polished finish for the tubes/pipes?

A: Yes, for welded tubes/pipes, we can do mirror polishing, 600# polishing, 500# polishing, 320# polishing, 240# polishing and so on, brushed finish is also available. For seamless tubes/pipes, normally the surface is pickled finish, while brushed finish is also doable.

Q: What’s your standard package?

A: Our standard package is waterproof plastic bags with wraps. For advanced packing, we can provide round paper tube for each tube, and wooden/metal case for exterior packing.

Q: Where’s your main market?

A: South America, Mid-east, South-east Asia, Europe and so on.

Q: Do you also have the accessories for the tubes?

A: Yes we can provide the accessories too.
