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
Al Yusr is a modern residential area of spacious villas and mid-rise blocks with adequate outdoor space, where central AC systems need complex ducting that runs through interior walls and horizontal passages. Workshop-fabricated ductwork ensures precise measurements and joints, cuts on-site installation time, and handles the multiple bends and takeoffs needed to serve several zoned areas.
Al Yusr, in north Jeddah, is a modern residential zone mixing spacious villas with planned apartment buildings.
Complex central AC systems here typically need ductwork with multiple bends and diameter changes across floors and separate zones.
The AC setup in Al Yusr
- 1
Complex rectangular duct with multiple bends
Villas here need irregular duct runs through rooms of different sizes, so we fabricate rectangular sections with bends and transitions to match the architect's drawings.
- 2
Multiple air branches and divisions
The central unit needs duct branches that divide air among the villa's different wings, each made to the right diameter for that zone's size.
- 3
Tight-jointed duct with no air loss
Workshop-made duct arrives with calibrated joints and tight seals, so no cold air is lost at the connections.
Before the visit
Before our visit in Al Yusr
- 1
Gather the site or villa floor plan
Send us architectural drawings or a clear photo of the villa plan before the visit so we can calculate duct length and bend requirements.
- 2
Mark where the indoor and outdoor units will sit
Tell us where the indoor and outdoor units will be mounted (usually on the roof or villa garden) so we calculate duct runs from the main trunk.
- 3
Confirm access to wall cavities and ceiling spaces
Check that wall cavities and suspended ceiling spaces are accessible during installation, and tell us about any obstacles like electrical wiring or water pipes.

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.
Our villas have complex layouts, does fabricated duct suit them?
Yes, we take your site drawings or villa plan and fabricate the duct to fit your exact internal pathways. It arrives complete with all the bends and takeoffs your layout needs.
The street is wide, but the space between walls indoors is tight, can you still fit the duct?
Pre-fabricated duct is narrower than a cut-piece, so it slides easily between walls and suspended ceilings. We take exact measurements on site and make it to fit the available space.
Heat is intense on the villa's external walls, does a central system cope?
Yes, correctly distributed ducting throughout the villa ensures even cold air spread, and precise fabrication minimises cold air loss over long runs.
Duct fabrication needs water drainage for condensation, are you familiar with drainage here?
The ductwork itself is metal and requires no drainage, but the central unit itself needs a condensate line. We install this as part of the overall system plan.
