Dedicated duct workshop
Duct fabrication in Al Nuzlah Al Sharqiyah
In Al Nuzlah Al Sharqiyah, south Jeddah, residential blocks and commercial shops are densely built, and central AC projects need standard duct with precise dimensions. Alrabih fabricates in the workshop to avoid site errors and delays.

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
- Elbows transitions and takeoffs
- Tight seams to SMACNA
- Labelled sections ready to hang
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 Nuzlah Al Sharqiyah is densely built with multi-storey residential blocks and narrow commercial passages, so central AC projects are constrained by available space and ceiling heights. Workshop fabrication lets us calculate dimensions precisely to fit the available space, and cuts waste from on-site cutting and repeated adjustments that add cost and delay.
Al Nuzlah Al Sharqiyah is in south Jeddah, a district of dense residential blocks and commercial shops in narrow passages.
Most central AC in Al Nuzlah Al Sharqiyah requires low-profile rectangular duct to run through tight ceiling spaces.
The AC setup in Al Nuzlah Al Sharqiyah
- 1
Low-profile rectangular duct
Residential blocks in Al Nuzlah Al Sharqiyah need flat duct that does not consume much of the limited ceiling space.
- 2
Branching networks across multiple floors
Multi-storey buildings need duct branches per floor with outlets in each flat, requiring precise fabrication.
- 3
Materials that are easy to route and install quickly
Fabricated duct arrives pre-finished to final dimensions, so installation is swift with no adjustments, reducing on-site time in busy buildings.
Before the visit
Before our visit in Al Nuzlah Al Sharqiyah
- 1
Obtain an architectural drawing of the building
Contact the building management or engineer and get a drawing showing the duct route and available spaces between ceilings.
- 2
Measure ceiling cavity height precisely
Before the visit, get precise measurements of the available cavity height in each area for the duct to pass through.
- 3
Inform us of outlet points and obstacles
Mark where air outlets will be in each flat and identify any pipes or columns that might obstruct the duct route.

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.
How do you handle tight ceiling spaces?
We measure the available ceiling height precisely, then fabricate flat-profile duct to exact dimensions that fit within the limit.
Can you work with AC projects in older apartment blocks with complex structures?
Yes, we work with the project engineer to understand the existing structure, and fabricate duct to fit the reality without major on-site modifications.
What duct types suit dense apartment blocks?
We use low-profile galvanized or aluminium rectangular duct for buildings with tight spaces, and sometimes flex duct where flexibility is needed.
Do you reduce material waste during fabrication?
Workshop fabrication reduces waste because we calculate dimensions precisely from the plan, unlike on-site cutting which leaves scrap pieces.
