Round tube

Fiberglass round tube for technical and industrial applications

At Polymec, we offer fiberglass round tubes for technical applications where a tubular profile with a circular section, mechanical properties and chemical properties is required.

We use this type of profile when we need a lightweight, safe and cost-effective component for solutions used in different environments, industries and sectors. The round geometry allows us to consider this product in assemblies where a fiberglass tube with defined dimensions and different weights per metre is required.

We offer a wide range of fiberglass round tube references, including standard options and references identified as reinforced, allowing the selection to be adapted to the needs of each project.

What is a fiberglass round tube?

A fiberglass round tube is a hollow profile with a circular section. This geometry allows it to be used in applications where a tubular, regular component that is easy to integrate into different types of assembly is required.

Within our range of fiberglass profiles, we recommend the round tube when the project requires a circular section and when the profile's external and internal dimensions are relevant to the final design.

Applications of the fiberglass round tube

We use fiberglass round tubes in projects where a technical profile with good mechanical and chemical properties is required. The current product sheet indicates that this product can be used in various environments, industries and sectors.

Mechanical and chemical properties of the profile

The fiberglass round tube has mechanical and chemical properties, according to the current product sheet. These properties help us assess the product when not only the tube's circular shape matters, but also the material's performance within the application.

When do we recommend a fiberglass round tube?

We recommend a fiberglass round tube when a tubular profile with a circular section is required and a lightweight solution is being considered for a technical project.

We also consider it when the design requires a round component, a specific dimensional reference or an alternative within the range of fiberglass profiles.

When there are specific requirements regarding assembly, load, operating environment, tolerances or supply, we review the case before confirming the final reference.

Related fiberglass profiles

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

• Fiberglass square tube.
• Fiberglass rectangular tube.
• Fiberglass U profile.
• Fiberglass Z profile.
• Fiberglass angle profile.
• Fiberglass flat bar.
• Fiberglass round rod.
• Fiberglass square rod.
• Fiberglass corner profile.
• Fiberglass half-round profile.

Frequently asked questions

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

We interpret the first measurement as the tube's external dimension and the second as the internal dimension indicated in the table. If the project requires a specific tolerance, we confirm this point against the technical data sheet.

Why are there several references with the same outside diameter?

There may be references with the same outside diameter and different internal dimensions. This allows us to compare options according to the available internal space, weight per metre and the function the tube must perform.

What information should be provided to choose a reference?

It is advisable to indicate the application, required dimensions, operating environment, the reference being considered, the type of assembly and any technical requirements related to weight, fit or tolerances.

When do we compare a round tube with a square or rectangular tube?

We compare them when the project allows for several geometries. We assess the round, square or rectangular format according to the available space, type of fastening and the function the profile must perform.
