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.

Q: What length is your standard length? Can I have the tubes/pipes cut into the length I want?

A: Our standard length is 3meter, 4meter, 5meter, 6meter. If you length is less than 3meter, we will have to run an additional processing for cutting which will bring some more costs. The minimum length is 500mm. For seamless tubes, we can make maximum to 12, 13meters.
