Carbon Steel Tube Profiles
Carbon steel tube profiles including C45 sections for machinery duty
What Carbon Steel Tube Profiles Is and Who It Is For
Carbon steel tube profiles cover the structural and machinery side of the tube programme, including sections in grades such as C45 where the tube has to be hardened or carry a running surface. The section is made to your drawing, so the tube arrives with the geometry the assembly needs rather than with a round section that has to be adapted.
Key Benefits
- Machinery grades such as C45 where the tube is a working surface
- Drawing defined sections in carbon steel
- Cut to length so the fabrication shop only assembles
- Supplied alongside the stainless tube programme
| Typical grade | C45 |
|---|---|
| Materials | carbon steel |
| Shapes | D section, triangle, oval, hexagonal and drawing defined |
| Delivery | cut to the length specified on the order |
Who It Is For
- Machinery manufacturers
- Fabrication shops buying cut sections
- Cylinder and actuator builders
- Equipment OEMs standardising on one tube supplier
Problems It Solves
- Structural round tube needs brackets welded everywhere something mounts
- Low grade tube cannot be hardened where the tube is a bearing surface
- Mill lengths force the fabricator to cut and scrap offcuts
Technical Features
- Carbon steel tube profiles to drawing
- Machinery grades including C45
- Cut to length delivery
- Straightened before shipment

How It Compares
Carbon steel tube profiles cost less than stainless and suit enclosed or painted service. Where the tube is exposed to a corrosive medium the stainless programme is the right one.
Use Guide
- State the grade if the tube will be hardened or ground
- Give the cut length so bundles arrive ready for assembly
- Send the mating parts if the section has to fit inside another tube
