What tube size do you need?

If you're not sure, we can calculate a size based on the size of your finished part and your machining parameters.  (See GTS, below).

 

What quantity do you need?

Miminum order is 10,000 pounds (4545 kilograms), except for CEVM or polyethylene commodity products, which have a minimum order quantity of 5,000 pounds (2270 kilograms).

 

What lengths do you want?

You can order random lengths, multiples or lengths cut to your specifications.

 

Do you have certain specifications that must be met?

All our steel is made to order, so we can meet your specifications, whether they be ASTM (American Society for Testing and Materials), AMS (Aerospace Material Specifications), MILS (Military Specifications) or some other.

 

What is the finished size of the part?

The GTS is based on the part's:

 

  • maximum finished OD
  • minimum finished ID
  • maximum finished part length
  • contour length, or the length of the major OD or ID that has a significantly larger OD or smaller ID than the rest of the part

 

What is the machining sequence?

Is the part chucked on the OD or ID?  Is it chucked at one or both ends?

 

What type of cleanup of OD and ID do you want?

 

  • "Full cleanup" is the removal of all surface imperfections (seams, decarb, scale, etc.)
  • "Bright metal cleanup" is the removal of the as-supplied surface, but not necessarily the removal of all surface imperfections.
