Description
This premium glass fibre square tube provides a lightweight yet exceptionally strong solution for a wide range of structural and framing applications. Manufactured from high-quality fibreglass, it offers an excellent strength-to-weight ratio, making it an ideal alternative to traditional metal sections where reduced weight and ease of handling are important.
Designed to withstand harsh environments, the tube is inherently corrosion resistant and non-conductive, making it suitable for use in industrial, marine, construction and electrical settings. With a compact 25 x 25 mm external profile, 3 mm wall thickness and a choice of convenient standard lengths, it is easy to integrate into new builds, repairs and custom fabrications.
Product Features
- External dimensions of 25 x 25 mm for a compact, versatile square profile.
- Robust 3 mm wall thickness providing strength and rigidity for structural use.
- Available in 2500 mm lengths (supplied as 2 x 2500 mm sections) for easier handling and transport.
- Single-piece 5000 mm length option for continuous runs and larger framework builds.
- Manufactured from premium glass fibre (fibreglass) composite for high performance and durability.
- Lightweight construction for simplified installation and reduced overall structure weight.
Key Features and Benefits
- Lightweight yet strong profile helps reduce handling effort, labour time and installation costs.
- Corrosion-resistant material is ideal for use in damp, coastal or chemically aggressive environments where metals may degrade.
- Non-conductive fibreglass construction improves safety around electrical installations and equipment.
- Low maintenance requirements and long service life help minimise replacement frequency and whole-life costs.
- Easy to cut, drill and machine using standard tools, allowing straightforward custom fabrication on site or in the workshop.
- Clean, uniform square section integrates neatly with brackets, fixings and other profile types for tidy, professional assemblies.

- Non-corrosive structures in marine, coastal or outdoor locations.
- Non-conductive supports and enclosures around electrical equipment and cabling.
- Machine guarding, safety barriers and protective frameworks.
- Custom fabrications, prototypes and structural assemblies in workshops and maintenance departments.
Frequently Asked Questions
Can the glass fibre square tube be cut to shorter lengths on site?
Yes, the tube can be cut to size using standard tools suitable for composites, such as a fine-tooth saw or abrasive cutting disc. Appropriate dust extraction and personal protective equipment are recommended when cutting or machining fibreglass.
Is this glass fibre square tube suitable for outdoor use?
Yes, the corrosion-resistant glass fibre construction makes it well suited to outdoor environments, including damp and coastal locations. As with all composites, exposure to strong UV over long periods may require consideration of protective coatings depending on the application.
Can this tube be used in place of metal for load-bearing structures?
The tube offers a high strength-to-weight ratio and is suitable for many light to medium duty structural applications. However, it should not be assumed to be a direct substitute for metal in all cases. Design calculations should be carried out to confirm suitability, taking into account loading, span and fixing details.
