Steel tubes for key clamp systems

Looking for strong and reliable steel tubes for your next project? At Keyclampshop.co.uk we supply high-quality galvanised tubes designed for use with key clamp fittings. These tubes are widely used for building handrails, guardrails, safety barriers, frames and industrial structures.

All tubes are available cut to size, allowing you to order the exact length required for your project. Combined with our modular key clamp system, you can create strong tubular constructions without welding.

Steel tubes for key clamp systems

Our galvanised steel tubes form the foundation of many tubular constructions. When combined with key clamp fittings, they allow you to quickly build strong and modular structures that can easily be adjusted or expanded.

Because the fittings clamp directly onto the tube, no welding is required. This makes installation faster, safer and more flexible compared to traditional welded structures.

Galvanised tubes for indoor and outdoor use

All tubes in our range are galvanised steel tubes, providing excellent corrosion resistance. This makes them suitable for both indoor and outdoor applications such as handrails, safety barriers and structural frames.

The galvanised coating protects the steel from rust and ensures long-term durability even in demanding environments such as warehouses, factories or outdoor installations.

Tube diameters and length options

We supply five standard tube diameters: 26.9 mm, 33.7 mm, 42.4 mm, 48.3 mm and 60.3 mm. Each diameter corresponds with compatible key clamp fittings, allowing you to create both light-duty and heavy-duty constructions.

Smaller diameters are often used for furniture or lightweight frames, while larger tubes are typically chosen for handrails, guardrails and structural safety barriers.

Tubes can be ordered in almost any length up to approximately 640 cm. To keep shipping efficient and economical, we recommend keeping tube lengths below 300 cm. Cutting to size is free of charge.

Common applications for steel tubes

Our galvanised tubes are used in many different construction and DIY projects, including:

• Safety handrails and guardrail systems
• Industrial barriers and warehouse protection
• Tables, benches and shelving structures
• Outdoor frames and structural supports
• Retail displays and exhibition frameworks

Frequently asked questions about tubes

Which tube diameter should I choose?
For smaller constructions such as furniture or lightweight frames, 26.9 mm and 33.7 mm tubes are commonly used. For handrails or safety structures, 42.4 mm or 48.3 mm tubes are usually recommended. The 60.3 mm tube is mainly used for heavy-duty or large structural projects.

Are the tubes suitable for outdoor use?
Yes. All our tubes are galvanised steel tubes, which means they are protected against corrosion and suitable for outdoor installations.

Do I need special tools to assemble tubes and fittings?
No welding or specialist equipment is required. Key clamp fittings are tightened with a simple Allen key, making installation quick and straightforward.
