Description
This premium glass fibre square tube provides a strong, lightweight alternative to traditional metal box section, ideal for a wide range of structural and framing applications. Manufactured from high‑quality glass fibre reinforced material, it offers excellent rigidity, dimensional stability, and long-term durability in demanding environments.
Available in a choice of external dimensions from 25 x 25 mm up to 60 x 60 mm, with wall thicknesses from 3 mm to 6.35 mm and lengths up to 5000 mm, these square tubes are well suited for frameworks, supports, enclosures, platforms, and general structural fabrication in industrial, commercial, and outdoor settings.
Product Features
- Range of external dimensions: 25 x 25 mm, 38 x 38 mm, 50 x 50 mm, 50.8 x 50.8 mm, and 60 x 60 mm to suit light to heavy-duty constructions.
- Multiple wall thickness options including 3 mm, 4.5 mm, 5 mm, and 6.35 mm for tailored strength and weight performance.
- Supplied in convenient 2500 mm lengths (2 x 2500 mm pack option) and longer 5000 mm lengths for larger builds and reduced joints.
- Glass fibre reinforced construction for high strength-to-weight ratio and excellent structural rigidity.
- Corrosion-resistant material suitable for use in wet, humid, or chemically aggressive environments.
- Electrically insulating properties compared with metal box section, ideal where non-conductive structures are required.
- Clean, uniform square profile for easy cutting, drilling, and integration into fabricated frameworks.
Key Features and Benefits
- Lightweight yet strong, making handling, transport, and installation easier while still providing robust load-bearing performance.
- Resistant to corrosion and degradation, helping to maintain structural integrity and appearance over time with minimal maintenance.
- Non-conductive material enhances safety in electrical or communication installations where metal profiles may not be suitable.
- Wide choice of sizes and wall thicknesses allows you to optimise strength, weight, and cost for each project.
- Easy to machine with standard tools, enabling straightforward cutting, drilling, and fixing on site or in the workshop.
- Suitable for indoor and outdoor use, supporting applications from industrial plant and marine environments to commercial and public spaces.

Frequently Asked Questions
Can the glass fibre square tube be cut and drilled with standard tools?
Yes, the tube can be cut and drilled using common tools such as fine-tooth saws and carbide or high-speed steel drill bits. It is recommended to use appropriate dust extraction and personal protective equipment when machining glass fibre materials.
Is this glass fibre square tube suitable for outdoor and marine environments?
Yes, the material offers good resistance to moisture and corrosion, making it suitable for outdoor and marine-related applications. However, as with all composites, service life will depend on the specific environment and loading conditions, so correct sizing and installation are important.
How do I choose the right size and wall thickness for my project?
Select the external dimension and wall thickness based on the required load-bearing capacity, span, and installation conditions. Smaller sizes and thinner walls suit lighter-duty frames, while larger dimensions and thicker walls are better for higher loads or longer unsupported spans. If in doubt, consult a structural engineer for guidance.
