Dedicated duct workshop
Duct fabrication in Radwa
In Radwa, north-east Jeddah, modern residential villas and apartment blocks need centrally ducted AC systems fabricated to precise standards. Alrabih fabricates rectangular and round duct in the workshop from galvanized or aluminium sheet, measured from site or plans, so it arrives ready to hang with no air leakage.

Who needs workshop-fabricated duct?
- 1
A contractor with project-specific sizes
Your project has non-standard sizes or volumes too large for site cutting. We fabricate rectangular and round sections from your drawings at exact dimensions, labelled and ready to hang when they reach the site.
- 2
Fittings too awkward to cut on site
Elbows, transitions, offsets and takeoffs come out distorted when cut by hand on site, leaking air and creating noise in the line. We make them in the workshop at the right dimensions with tight seams.
- 3
Extending or renovating an existing duct network
You need new branches, a damaged section replaced or a fitting that matches an old duct size. We measure the existing network on site and fabricate the pieces to match what is already there.
Who it's for
Building a facility that needs non-standard duct sizes
We read your project drawings and fabricate all sections and fittings at exact dimensions from G90 or aluminium sheet, labelled and ready to hang the moment they reach your site.
Ask on WhatsAppRenovating home AC and need fittings to match old duct
We measure the existing ductwork in your home and fabricate the branches, transitions and elbows needed to match the original duct without replacing the whole network.

How we work
How we work
- 1
Take measurements
A technician visits the site or you send us the drawings; we list every duct section needed, its size and the correct sheet thickness for that section.
- 2
Fabricate sections and fittings
We cut, form and lock the sheet in the workshop, including all elbows, transitions, offsets and takeoffs, and each section comes out at its exact dimension.
- 3
Label and prepare for delivery
We number every section and fitting against the assembly plan so the installation crew knows exactly where each piece goes, with no guessing on site.
- 4
Deliver to site
We deliver the duct to your Jeddah site protected and ready to hang. If you need an installation crew, we can arrange that as a separate step.
Workshop fabrication or site cutting?
| Alrabih | The usual way | |
|---|---|---|
| Dimensional accuracy | Workshop machines, tight dims | Hand variation on site |
| Complex fittings | Correct elbows and transitions | Distorted, leaking air |
| Seam quality | Tight lock, low leakage | Gaps weaken pressure |
| Site schedule | Arrives ready to hang | Extra time and site noise |
| Salt and humidity | Aluminium where site demands | One sheet regardless |

What sets this district apart
Radwa is a relatively modern area with spacious villas, multi-storey apartment blocks and some commercial complexes, and adequate spacing between buildings allows for central ductwork runs. However, new projects in Radwa require duct fabricated to tight tolerances to fit suspended ceilings and internal passages, and rough on-site cutting loses the precision needed for proper fittings and transitions. Pre-fabricated duct from the workshop ensures correct alignment, faster installation and better cooling efficiency.
Radwa lies in north-east Jeddah, a relatively new area of spacious villas and large residential buildings.
Most modern villas and apartment blocks in Radwa use a central duct system requiring precise measurements and complex transitions and bends.
The AC setup in Radwa
- 1
Rectangular duct for spacious apartment blocks and villas
Most modern residential projects in Radwa use rectangular duct to fit suspended ceilings and wider internal passages.
- 2
Round duct for branches and secondary outlets
Secondary outlets and smaller branches in modern villas and flats often use lighter round duct.
- 3
Precise transitions and bends in the workshop
Every bend, transition and takeoff is cut in the workshop to plan, leaving no room for on-site error.
Before the visit
Before our visit in Radwa
- 1
Provide drawings or site measurements
Send project drawings or site photos with passage and ceiling dimensions so we can fabricate duct accurately.
- 2
Confirm the locations of main distribution and outlets
Make sure you know the number of outlets and their locations before the visit, so we fabricate the right number of transitions.
- 3
Tell us about the site's architectural constraints
Any architectural constraints like ceiling height, narrow passages or suspended beams affect duct fabrication, so mention them beforehand.

FAQ
Questions about Duct fabrication
Can you fabricate from drawings without visiting the site?
Yes, when the drawings are clear and carry the actual as-built dimensions. If a dimension is uncertain or a field change has been made, we prefer a site visit to avoid a fabricated piece that does not fit. We discuss the better approach with you before starting work.
What is the difference between galvanized and aluminium sheet for duct?
G90 galvanized sheet is the standard choice for interior duct: strong and suited to a range of pressures. Aluminium is lighter and handles Jeddah's coastal humidity and salt air better, making it right for some exposed applications or where structural load is a limiting factor. The correct choice depends on the site.
Can you make elbows and transitions to match an existing duct network?
Yes. We measure the existing network on site to match sizes precisely, whether you need a new branch added, a damaged fitting replaced or an extension tied into the original ductwork. The right approach is confirmed after the site visit.
How do you choose sheet thickness for each section?
Thickness follows section size: a large duct needs heavier sheet to hold its shape under pressure, a small one can use lighter material. We apply the SMACNA requirements to each section in the project individually, not a single thickness across the whole job.
Does Jeddah's humidity and salt air affect which sheet material to use?
Yes, particularly for sections exposed to outdoor air or installed near fresh-air intakes. G90 galvanized sheet performs well inside the building, but aluminium is the better choice where duct is in continuous contact with Jeddah's humid, salt-laden air. The site survey determines the right material for each section.
Do you cut duct on-site or fabricate it in the workshop first?
We fabricate the entire duct in the workshop from galvanized or aluminium sheet to your site measurements or plans, with precise transitions and bends, arriving ready to hang with no air loss.
Radwa villas need duct that fits suspended ceilings, can you manage that?
Yes, we coordinate to your ceiling height and internal passages, and fabricate rectangular or round duct custom-made to your drawings or site measurements.
New projects in Radwa need complex transitions and takeoffs, how do you keep them accurate?
We cut and bend the sheet accurately in the workshop to your plans and measurements, rather than improvising on-site, which loses alignment and fit.
Does fabricated duct need special preparation before hanging in modern villas?
The duct arrives clean and ready to hang, and we coordinate with the site team to ensure proper alignment with the distribution points and outlets.
