Spiral Tube Colour Ducting – Custom RAL Finish

Overview

A client required high-quality spiral tube ducting that would remain fully visible within the finished space. Because the services formed part of the interior design, the ductwork needed to match specific brand and architectural colours rather than standard galvanised metal.

Our brief was simple:

• Supply spiral duct
• Apply a durable decorative finish
• Match any RAL colour
• Deliver on programme

The Challenge

Exposed HVAC systems are increasingly a design feature. Standard silver galvanised duct can conflict with:

• Brand colour schemes
• Ceiling palettes
• Wayfinding concepts
• Retail or leisure aesthetics

The client needed a consistent, repeatable finish across all duct sections and fittings, with no delays to installation.

Our Solution

We supplied factory-finished spiral tube ducting, powder-coated to the client’s nominated RAL colour references.

What we delivered:

• Spiral tube in the required diameters
• Matching bends, reducers, tees, and fittings
• Uniform powder-coat coverage across all components
• Protective wrapping for transport and site handling
• Sequenced delivery aligned with the installation programme

Because coating was completed before dispatch, contractors were able to install immediately, with no painting or finishing required on site.

The Result

• Perfect colour consistency
• Faster installation
• No mess or follow-on trades
• A clean, architectural finish
• Reduced project risk

The exposed ductwork became a design asset rather than something to hide.

What We Offer

We manufacture and supply:

• Spiral tube duct
• Full range of fittings
• Protective transport packaging
• Powder coating to ANY RAL colour

Whether the requirement is bold and vibrant or subtle and industrial, we can match the finish to suit the project.

Structural Duct Support Installation – Smurfit Westrock

A couple of months back, Alpha Tube Co – Ductwork & Ventilation Specialists undertook a major structural support project for one of our long-standing customers, Martyn Tomlinson Building, at the Smurfit Westrock facility.

We manufactured seven universal cantilever arms, each standing 4.5 metres tall, designed to support a 1320 mm diameter duct. The system was engineered to safely carry the full load of a 20-metre-long duct section.

Scope of Works

• Manufacture of seven bespoke cantilever support arms
• Design to support a 1320 mm diameter duct system
• Powder-coating preparation using our in-house coating booth
• Structural installation and controlled lift on site

Engineering & Installation Approach

To ensure durability and long-term corrosion resistance, we set up our own powder-coating booth and applied a protective undercoat to each beam prior to installation.

The complete system was designed to take the full weight of the duct and lift it 700 mm in a single operation. Detailed planning and precise fabrication allowed the lift to be completed safely and efficiently in one morning.

Outcome

The installation was completed smoothly and on schedule. The cantilever system now provides a robust, long-term structural solution for the ductwork, meeting both performance and safety requirements for the site.

Major Ventilation Upgrade at Salford Royal Hospital

Our team successfully completed the replacement of three large-scale extraction fans at Salford Royal Hospital as part of a wider initiative to improve air quality and ventilation efficiency throughout the facility. These critical systems help maintain safe, hygienic airflow in clinical environments, making the upgrade essential to hospital operations.

Client: Salford Royal Hospital (Northern Care Alliance NHS Foundation Trust)

Scope of Works

• Removal of three end-of-life extraction fans
• Installation of three new high-capacity units
• Testing, commissioning, and integration into the existing ventilation network
• Completed within a live hospital environment with strict safety controls

Key Challenges

1. Restricted Access to Plant Area
Access was limited to a small hatch, barely large enough to manoeuvre each fan through. Precise measurement and specialist lifting solutions were required to avoid building fabric damage.

2. Heavy Lifting in a Sensitive Environment
All work was carried out on a plant roof above active clinical areas. A detailed lifting plan, strict noise and vibration controls, and full coordination with the hospital estates team ensured zero disruption.

Solutions & Approach

• Specialist Rigging & Lifting Strategy using compact lifting frames suitable for tight spaces.
• Phased Removal & Installation, breaking down and reassembling each fan in situ.
• Daily Collaboration with Hospital Teams to maintain clinical continuity.
• Quality-Focused Commissioning to balance and optimise airflow performance.

Outcome

The project was delivered safely, on schedule, and without any operational disruption. The new installation significantly improves extraction performance, supports compliance with HTM requirements, and future-proofs air delivery across key hospital areas.

Client Benefits

• Improved ventilation performance across the hospital
• Lower risk of breakdown thanks to modern, reliable equipment
• Enhanced control and balancing of extraction systems
• Future-proofed airflow for clinical and plant areas

Spray Booth Installation – Franklin Products

We’re proud to announce our first major spray booth project! We recently supplied two 3-metre booths and one 4-metre booth for Franklin Products in Milton Keynes. One unit is ducted externally, while the other two are recirculating booths equipped with advanced filter systems.

All booths were fabricated, assembled, and delivered complete with fans, filters, and lighting. We also carried out the external ducting on one booth, ensuring a durable, weather-sealed connection to the corrugated roof.

This project marks an exciting step forward for us as we continue expanding our capabilities in custom spray booth design and installation.

Extraction Hood and Local Ducting Systems

We installed a large extraction hood and ducting system (11 metres long by 4 metres wide) as a local extract system for a work area, helping create a safer and cleaner environment.

How It Works

• The extraction hood pulls contaminated air into the ducting system.
• The air is removed safely from the building.
• The system is efficient, quiet, and long-lasting.
• Constructed from durable, corrosion-resistant materials.
• Easy to maintain and built for long service life.

The project was completed on time with excellent results and improved air quality for workers.

Stainless Steel Canopies

We manufacture and install high-quality stainless steel canopies, paired with full ventilation systems including baffle filters, ducting, and extraction fans.
