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
Harat Al Yemen is among Jeddah's oldest quarters, marked by tightly built blocks, relatively low ceilings and very narrow passages between shops and flats. Pre-fabricated duct is invaluable here because spaces are severely tight with little room for on-site work; the duct arrives precisely measured to actual voids. This cuts mess, delays and field changes that could damage the old structure.
Harat Al Yemen lies at the heart of historic downtown Jeddah, an old residential-commercial district of tightly built blocks and low ceilings.
Most available duct spaces in Harat Al Yemen are very tight, requiring small standard sections or slim-profile round duct.
The AC setup in Harat Al Yemen
- 1
Slim-wall round duct for tight spaces
Most duct runs in Harat Al Yemen use slim-profile round duct to fit the constrained voids between buildings and under low ceilings.
- 2
Small standard duct sections
Fabricated sections are small and standard for easy transport and assembly through narrow hallways and inside flats and shops.
- 3
Strong metal joints with no losses
Couplings between sections are robust metal fittings sealed tight to ensure no air loss at confined joints.
Before the visit
Before our visit in Harat Al Yemen
- 1
Precise measurement of available voids
Before the visit, ensure ceiling and wall voids are accessible, and tell us of any structural obstacles limiting the duct route.
- 2
Coordinate with flat or shop occupant
Inform the flat or shop owner of the visit time and ensure ceiling and internal corridor access without disturbing neighbours.
- 3
Check ceiling and wall condition
Old buildings may have structural weaknesses; ensure ceilings and walls can safely bear the duct and metal supports before installation.

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.
The buildings here are old and very tight; can you fabricate duct for small voids?
Yes, we fabricate small standard sections and slim-wall round duct fitting the tight voids in old buildings.
The ceilings are low; how do you route duct through narrow halls and rooms?
We map the available voids precisely on the site visit, then fabricate duct sections fitting the space exactly, avoiding field rework.
Old downtown humidity affects aged metal ductwork; does it affect new duct?
New galvanised sheet resists rust better than aged metal, but high humidity and salt from the nearby sea may accelerate oxidation; we recommend periodic maintenance.
Does workshop duct suit the deteriorating ceilings in old homes?
Yes, but we recommend inspecting the building's ceiling and structure before installation, and coordinating with the owner on any ceiling repairs needed before hanging the duct.
