Galvanised key clamps are designed for building durable and corrosion-resistant tube constructions. Manufactured from high-quality steel and finished with a hot-dip galvanised coating, these fittings offer excellent protection against rust and weather exposure.

Combined with our galvanised steel tubes, key clamp fittings create strong and reliable structures for both indoor and outdoor applications.

Durable and weather-resistant fittings

Each key clamp is protected with a thick zinc layer applied through a hot-dip galvanising process. This coating prevents corrosion and allows the fittings to perform reliably even in demanding environments such as industrial sites, outdoor installations and public spaces.

The result is a low-maintenance construction system that remains strong and stable for many years.

Simple and reliable construction system

Key clamp fittings are designed for quick and straightforward installation. The integrated set screw secures the tube firmly in place without welding, threading or specialist tools.

Using a simple Allen key, you can create a secure connection that is both strong and adjustable. This modular system makes key clamps ideal for professional installations as well as DIY projects.

Applications of galvanised key clamps

Galvanised key clamps are widely used for a variety of structures, including:

Outdoor handrails and guardrails
Canopies, verandas and fencing structures
Industrial and warehouse frameworks
Outdoor furniture and benches
Temporary or permanent event structures

Precision fit for multiple tube sizes

Our key clamps are available for five tube diameters: 26.9 mm, 33.7 mm, 42.4 mm, 48.3 mm and 60.3 mm. Each fitting is designed to match the corresponding tube size, ensuring a precise and secure connection.

The internal diameter of the clamp is slightly larger than the tube diameter, allowing easy installation while still providing a strong and stable grip once the set screw is tightened.

Quality materials and tested performance

All fittings are manufactured from high-quality steel to ensure strength and durability. Selected ranges have been TÜV certified for load-bearing capacity and slip resistance, making them suitable for professional and safety-critical applications.

Fast delivery and expert support

All key clamp fittings are stocked in the UK for fast dispatch. At Keyclampshop.co.uk, we combine reliable product quality with practical advice to help you select the right fittings and tube sizes for your project.
