What is Ductwork?

ductworkFleetwood Sheet Metal can offer a full production cycle from design (by external design engineers) to manufacture, installation and testing. We enjoy an excellent reputation across the North West UK working for many high profile contractors.

We operate out of purpose built factory with our professional experienced workforce. Our projects cover many sectors from chemical plant work to standard office ventilation, local government buildings, leisure and public buildings. We can offer standard galvanised ventilation systems, fire rated, stainless steel bespoke systems, plastic, etc this includes the supply and installation of all plant, grilles, diffusers and other ancillary equipment.

This is backed up by our experienced team of project management engineers, CAD/CNC designers, manufacturing and installation specialists to ensure the project is completed to our exacting standards within your timescale.

ductworkWhat is Ductwork? – An Overview

Ductwork is used in heating, ventilation, and air conditioning (HVAC) to provide and extract air. These airflows include, supply air, return air, and exhaust air. Ductwork is one method of ensuring acceptable indoor air quality as well as heating or cooling requirements.

Main Ductwork materials

The main ducting materials used to construct rectangular, round, or oval cross-sectional shapes are:

Galvanised steel

Galvanised steel can easily be cut and bent to form ductwork so is the most commonly used material. It can be wrapped or lined with thermal insulation, both to reduce heat loss or gain through the duct walls and water vapour from condensing on the exterior of the duct when the duct is carrying cooled air. Insulation, particularly duct liner, also reduces duct-borne noise. Both types of insulation reduce ‘breakout’ noise through the ducts’ sidewalls.

Polyurethane duct board

More rectangular ductwork is being manufactured from “duct board”, thanks to the fact that custom or special shapes and sizes of ducts can easily be shop or field fabricated. The ductwork construction starts with the plotting of the single pieces on the panel. The pieces are then, bent and closed through an operation of gluing, pressing and taping. Having obtained the various ductwork sections, they can easily be installed by using an invisible aluminium flange system.

Fibreglass duct board

Fibreglass panels provide built-in thermal insulation and the interior surface absorbs sound, helping to provide quiet operation of the HVAC system.

Flexible tubing

Flexible ducts, known as flex, have a variety of configurations, but for HVAC applications, they are typically flexible plastic over a metal wire coil to make round, flexible duct. Flexible duct is very convenient for attaching supply air outlets to the rigid ductwork but pressure loss is higher than for most other types of ducts.

Ductwork system components

Complete ducting systems contain many other components:

  • > Vibration isolators
  • > Terminal units
  • > Air terminals
  • > Take-offs
  • > Stacks, boots, and heads
  • > Dampers

Fleetwood Sheet Metal can provide the full system and advise on the best application for your environment, please contact us for more details.

Capabilities

Metal Fabrication Capabilities

Fleetwood Sheet Metal have the facilities to manufacture almost any products using Mild Steel, Galvanised Steel, Stainless Steel, Aluminium, Copper and Brass. Covering 12000sq feet with a 10 tonne capacity crane. Fleetwood Sheet Metal’s fabrication workshops can meet the demands and requirements of all its customers needs.

Welding

All our fabricator welders are certificated to B.S EN 287 covering a wide range of steels such as carbon and alloy steels, nickel alloys and non ferrous materials.

Employing OXY/ACT, MMA, MIG/MAG and TIG welding processes and adopting the correct pre-heats, inter pass temperature and post-heat requirements within the procedure, Fleetwood Sheet Metal can meet the stringent demands of most applications.

Quality Contol

We have full quality control testing available for all products on site and having a machining function alongside our fabrication facilities, we offer the customer an important option when sub-contracting work.
