Carbon fiber profiles

Round tube

Round carbon fiber tubes have excellent mechanical and chemical properties. Being made from carbon fiber, they offer greater strength and durability than other materials. This allows them to be used in various environments, industries and sectors. It is a lightweight, safe and cost-effective material that fully meets the customer’s needs.

Carbon profiles

Information

Carbon fibre round tube for technical and industrial applications

At Polymec, we offer carbon fibre round tubes for technical applications where a tubular profile with a circular cross-section, low weight and good mechanical and chemical performance is required.

We work with this type of tube when we are looking for a lightweight, safe and cost-effective component with greater strength and durability than other materials. The current product datasheet indicates that it can be used in a wide range of environments, industries and sectors.

We offer a wide range of carbon fibre round tube references with defined dimensions, weight per metre and minimum order quantity in metres, allowing us to guide the selection according to the needs of each project.

What is a carbon fibre round tube?

A carbon fibre round tube is a hollow profile with a circular cross-section. This geometry allows us to use it in assemblies where a tubular, regular component that is easy to integrate into a technical solution is required.

Within our range of carbon fibre profiles, we recommend the round tube when the design requires a circular cross-section and when the outer and inner dimensions of the tube are relevant to the assembly.

Applications of carbon fibre round tubes

We use carbon fibre round tubes in projects where a technical profile with mechanical and chemical properties is required.

This format can be considered when we are looking for a lightweight tubular component with defined dimensions and different weight-per-metre options.

When do we recommend a carbon fibre round tube?

We recommend a carbon fibre round tube when a lightweight tubular profile with a circular cross-section and different dimensional options is required.

We also consider it when the project requires a carbon fibre component with good mechanical and chemical performance, especially when weight, geometric precision and integration with other components are relevant factors.

When there are specific requirements regarding load, stiffness, fit, tolerances, exposure, assembly or minimum order quantity, we review the case before confirming the final reference.

Related carbon fibre profiles

If the round tube does not suit the geometry required, we also offer other carbon fibre profiles that can be considered depending on the application:

  • Carbon fibre flat bar.
  • Carbon fibre half-round profile.
  • Carbon fibre round rod.
  • Carbon fibre square rod.

Frequently asked questions

What information do we need to recommend a round tube reference?

We need to know the application, approximate dimensions, operating environment, the function of the tube within the assembly and any requirements related to weight, fit, stiffness or supply.

How do we interpret the two dimensions shown for each reference?

We review the dimensions indicated in the table and confirm in the technical datasheet whether they correspond to the outer and inner diameters before using them as technical data in the project.

When do we compare a round tube with a carbon fibre round rod?

We compare both profiles when the project allows a circular cross-section but we need to choose between a hollow and a solid component. The choice depends on the assembly, weight, available space and the function the component must perform.

Why are there references with the same outer diameter but different weights?

This may be due to differences in the second dimension shown, which affect the amount of material in the tube. We review each reference before confirming which one best suits the design.

What should we review if the tube is integrated with other components?

We review the fit, available clearance, fastening system, required tolerances and expected performance within the assembly before confirming the reference.
