Powder coating handrails offers several advantages, including durability, aesthetic appeal, and low maintenance. It provides a protective layer against rust, corrosion, and environmental elements, ensuring long-lasting performance.
Frequently Asked Questions
What is a Key Clamp?
A Key Clamp fitting (also known as a tube clamp or pipe clamp) is a modular slip-on connector that joins metal tubing or steel pipe without welding. The fitting slides onto the tube and is tightened with a set screw using an Allen key (hex key).
- No welding, threading, or hot works required
- Provides a strong, stable, and reusable joint
- Ideal for both permanent and temporary structures
What can you build with Key Clamps?
Key Clamps are versatile and widely used in:
- Handrails and guardrails for stairs, ramps, and walkways
- Safety barriers and access control systems
- Industrial and retail shelving
- Playground equipment, sports frames, and outdoor structures
- Exhibition stands, event barriers, and temporary frameworks
- Bespoke designs such as furniture frames, canopies, and storage racks
What tube sizes are compatible with Key Clamps?
We supply Key Clamp fittings in the most common tube diameters:
- 26.9mm (Size A)
- 33.7mm (Size B)
- 42.4mm (Size C)
- 48.3mm (Size D)
- 60.3mm (Size E)
This allows everything from lightweight garment rails to heavy-duty handrail systems.
What is a galvanised finish?
Key Clamps are supplied with a hot-dip galvanised finish, providing excellent corrosion resistance and long service life. This makes them suitable for both indoor and outdoor applications, even in harsh or coastal environments.
What are powder-coated Key Clamps?
Powder-coated Key Clamps are galvanised fittings finished with a tough, coloured powder layer. This process:
- Enhances appearance with a professional finish
- Adds an extra layer of corrosion resistance
- Extends lifespan in demanding environments
Are Key Clamps easy to install?
Yes. Key Clamps are designed for fast installation with only an Allen key required to tighten the set screw. No welding, threading, or specialist training is needed, making them ideal for DIY projects and professional installations.
Can Key Clamps be used for temporary structures?
Yes. Thanks to their modular design, Key Clamps are perfect for temporary frameworks. They can be assembled, dismantled, stored, and re-used with ease.
Do you offer tubes cut to size?
Yes. We provide a cut-to-size tube service from 100mm to 6400mm, so your steel tubing is ready to install without the need for on-site cutting.
How strong are Key Clamps?
When tightened correctly, Key Clamps provide a very secure joint capable of supporting heavy axial loads. They are widely used in safety-critical applications such as handrail systems and barrier frameworks.
Are they compliant with safety standards?
Yes. Our Key Clamp fittings are manufactured to recognised international standards for malleable iron castings and galvanised finishes. They are TÜV-tested for quality and load performance, ensuring they meet strict safety and durability requirements for both commercial and industrial use.
Why use Key Clamps instead of welding?
- No welding equipment, hot work permits, or specialist skills needed
- Faster, safer installation process
- Lower labour and maintenance costs
- Easy to adapt, extend, or dismantle structures
- Long-lasting, durable, and reusable fittings
- TÜV-tested for strength and reliability
How long will delivery take?
- Stocked items: 1-2 working days (UK Mainland)
- Pre-built posts & self-closing gates: 2-4 working days
- Powder-coated fittings and tubes: 7-10 working days
Deliveries exclude weekends and bank holidays. If you have an urgent order, please contact our Sales Team to confirm availability.
Do you deliver outside of the UK Mainland?
Yes. We can arrange delivery to offshore UK locations and international addresses. Please contact us for a quotation.
Can I return or exchange items?
Yes, unused and resaleable items can be returned within 14 days of delivery. Please note: cut-to-size tube and powder-coated fittings are non-returnable due to their custom nature.
What are DDA Key Clamps?
DDA Key Clamps are specially designed fittings used to create handrail systems that comply with the Disability Discrimination Act (DDA) and current Building Regulations (Part M). These fittings ensure that handrails are smooth, continuous, and comfortable to grip, making public spaces more accessible for wheelchair users, people with reduced mobility, and the visually impaired.
What makes a handrail DDA-compliant?
- Handrails must provide a smooth, continuous run without sharp edges or obstructions
- Joints should be flush and snag-free for user comfort and safety
- Handrails must be securely fixed at the correct height (900–1000mm for ramps and stairs)
- Colour contrast options (via powder-coated finishes) help visually impaired users distinguish the handrail from the background
Where are DDA Key Clamp handrails used?
DDA-compliant handrails are commonly installed in:
- Public buildings (schools, hospitals, offices, transport hubs)
- Residential developments
- Commercial premises
- Ramps, stairways, and access routes
Do your DDA Key Clamps meet regulations?
Yes. Our DDA Key Clamp fittings are TÜV-tested and manufactured to provide safe, compliant, and durable handrail systems that meet both DDA and Part M Building Regulation requirements.
