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.

What the fabrication covers
- Site measure or drawings
- G90 or aluminium duct

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 Zumurrud is a modern district of tall residential towers and large commercial projects, whose open design lets long central duct runs cross suspended ceilings without major architectural obstacles. On-site duct cut cannot hold the tight tolerances and complex fittings these large buildings demand, so workshop fabrication from site measurements ensures perfect alignment and no air loss at the joints.
Al Zumurrud sits in north Jeddah, a district of modern high-rise residential towers, hotels and commercial blocks with open architectural design.
Most of the residential towers and hotels here use high-capacity central duct systems that demand precise fabrication to avoid leakage.
The AC setup in Al Zumurrud
- 1
Central duct for large distribution systems
Al Zumurrud towers need high-capacity central duct to distribute air across multiple floors, and workshop fabrication achieves the precision required.
- 2
Complex offsets and elbows
Buildings with complex layouts need elbows at various angles and precise offsets that the workshop can fabricate without delay.
- 3
Smooth transitions between duct diameters
Air flow from large main duct to smaller branches requires engineered transitions, and our fabrication provides these with high precision.
Before the visit
Before our visit in Al Zumurrud
- 1
Bring engineering drawings or the site plan
If you have drawings from the engineer, bring them or send them before the visit to speed up fabrication.
- 2
Mark the planned duct routes
Ask the construction team to clearly mark the duct routes on the suspended ceilings before our site measurement.
- 3
Ensure space for loading and unloading
Prepare adequate space at the site to safely unload the long duct lengths when they arrive.

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.
Is on-site duct adequate for the tall residential towers here?
No, the towers need complex duct with precise turns and offsets that on-site fabrication cannot maintain. Workshop production ensures exact tolerances with zero leakage.
How do you deliver the fabricated duct safely to the site?
We fabricate duct in transportable lengths with protective wrapping to prevent damage during delivery and unloading at the building site.
Does coastal humidity and sun heat affect the duct metal?
We use either galvanized steel or aluminium depending on the environment and specs; galvanized resists the humidity and salt in Jeddah's coastal air.
Does duct fabrication need precise engineering drawings from the site engineer?
Engineering drawings are preferred, but we take our own site measurements if they are not available and convert them into precise duct designs in the workshop.
