Description
This premium heavy duty HDPE square tube is a robust, versatile engineering plastic profile designed for demanding construction, framing and protection tasks. Supplied in a convenient 50 m pack, comprising 10 straight 5 m lengths, it provides a durable and consistent solution for building rigid frames, guards, covers and enclosures.
Manufactured from high density polyethylene in a solid black finish, this square tube offers excellent impact resistance, weatherability and chemical resistance. Its 50 x 50 mm external dimensions and 4 mm wall thickness make it ideal for both indoor and outdoor use in workshops, production areas, agriculture, transport and general engineering applications.
Product Features
- External square profile of 50 x 50 mm for strong, balanced framing and support structures.
- Heavy duty 4 mm wall thickness for enhanced rigidity and long-term durability.
- Manufactured from high density polyethylene (HDPE) for excellent impact and wear resistance.
- Supplied in black for a smart, uniform appearance and improved UV resistance.
- Total length of 50 m per pack, supplied as 10 x 5 m straight lengths for easier handling and cutting.
- Suitable for machining, drilling and cutting with standard workshop tools.
- Consistent dimensional tolerances for reliable fit with brackets, fixings and mating components.
Key Features and Benefits
- Provides a strong yet lightweight alternative to metal tubing, helping to reduce overall structure weight and ease installation.
- Resistant to corrosion, moisture and many common chemicals, minimising maintenance requirements in harsh environments.
- Non-conductive material improves safety where electrical insulation or reduced heat transfer is required.
- Weather and UV resistant black HDPE is suitable for long-term outdoor use without significant degradation.
- Supplied in standard 5 m lengths, making it straightforward to cut to size for bespoke frames, guards and covers.
- Smooth, easy-to-clean surface supports good hygiene in food, agricultural and workshop settings.

Frequently Asked Questions
Can this HDPE square tube be cut and drilled with standard tools?
Yes, the HDPE tube can be cut with common woodworking or metalworking saws and drilled using standard drill bits. Using sharp tools and appropriate clamping will help achieve clean, accurate cuts and holes.
Is the black HDPE square tube suitable for outdoor use?
Yes, the black HDPE material offers good resistance to weathering and UV exposure, making it suitable for long-term use outdoors in frames, guards and covers.
Can this tube be used as a direct replacement for metal box section?
It can be used as an alternative to metal box section in many light to medium duty applications, offering advantages such as corrosion resistance and lighter weight. However, it does not have the same load-bearing capacity as metal, so suitability should be checked against the specific mechanical requirements of your project.
