Dedicated duct workshop
Duct fabrication in Al Sabeel
In Al Sabeel in central Jeddah, modern and mid-rise buildings use extensive central AC ductwork, yet site-cut duct loses the dimensions and detail these systems need. We fabricate rectangular and round duct with precision in our workshop, so it arrives ready to install quickly and with no air loss.

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 Sabeel features a mix of mid-rise residential blocks, offices and smaller hotels, mostly built in recent decades with wider interior spaces than old-town districts, yet central ductwork here is complex, spanning multiple floors and different sections. Workshop fabrication saves time and ensures precision, as sections arrive ready for immediate installation and reduce the risk of poor joints and air leaks that harm cooling efficiency.
Al Sabeel sits in central Jeddah between Al Balad and the northern districts, a zone of mid-rise residential blocks, offices and smaller hotels.
Al Sabeel's networks blend rectangular duct in passages and concealed ceilings with smaller round duct in branch runs.
The AC setup in Al Sabeel
- 1
Rectangular duct in concealed ceilings
Most hotels and offices in Al Sabeel use suspended ceilings, so we fabricate rectangular duct that fits the limited height precisely.
- 2
Round branches for air distribution
Secondary branches reaching rooms and offices are round for ease of installation and quick connection.
- 3
Transition pieces from rectangular to round
We fabricate transition pieces connecting the main rectangular duct to round branches, keeping the network uniform and air loss minimal.

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.
We have a small hotel with AC ductwork spanning multiple floors, can you handle that?
Yes, we fabricate complex multi-floor ductwork in our workshop to drawings or full survey, so each section arrives ready to connect easily on every floor.
The hotel needs duct hidden in the suspended ceiling, does that affect fabrication?
No, we measure the suspended ceiling and available space before fabrication and section the duct to fit precisely within the limited ceiling height.
The air in Al Sabeel carries dust from busy roads, does that affect duct metals?
Dust affects outlet maintenance rather than the metals themselves, but we use G90 galvanized steel and aluminium to protect duct from corrosion over time.
Our building has old and new sections, how do you run duct between them?
We measure each section separately and fabricate transition pieces that connect them smoothly, so no on-site adjustments are needed.
