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
Abhur Al Shamaliyah is a modern district with large villas, apartment blocks and hotels, all relying on central AC with complex duct runs through roofs and storeys. On-site hand fabrication cannot hold the precision needed for complex transitions and offsets, but the workshop delivers accurate measurement and uniform manufacture, so duct arrives leak-free and ready to install.
Abhur Al Shamaliyah is in northern Jeddah, a modern district of residential and hotel buildings with complex central systems.
Most residential and hotel projects here use rectangular ductwork with multiple bends and complex transitions between storeys.
The AC setup in Abhur Al Shamaliyah
- 1
Rectangular ductwork for central systems
Residential and hotel projects in Abhur use complex rectangular ductwork with multiple bends and transitions to distribute air across different storeys and sections.
- 2
Round ductwork for branch runs and takeoffs
Branches from the main duct to indoor units in flats and hotel suites are often round section for easier installation and maintenance.
- 3
Complex transitions and bends between storeys
Modern projects require duct with precise angles and transitions to prevent leaks and noise, fabricated on workshop machinery to high tolerance.
Before the visit
Before our visit in Abhur Al Shamaliyah
- 1
Obtain system drawings or site measurements
Provide engineering drawings for the system or planned duct runs, or arrange for our team to take precise measurements before fabrication begins.
- 2
Confirm site access for delivery
Fabricated duct is long and needs adequate wide access to reach the roof or storeys, confirm that the site allows the truck to deliver and unload safely.
- 3
Coordinate with the installation contractor or site supervisor
Inform the contractor or site supervisor of the delivery date and expected quantities, to prepare the site and provide labour for unloading and hanging on the same day.

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.
Why is workshop duct fabrication better than cutting on site?
Hand cutting on site cannot maintain precise dimensions or produce fittings that match complex bends. The workshop delivers uniform measurement and precise fabrication, so duct arrives with sealed joints and no air loss.
How do you transport duct to the site in Abhur Al Shamaliyah?
Finished duct is loaded on a flat-bed truck and delivered complete to the site, with no need for extra cutting or assembly on the roof or between storeys.
Hotel projects here need precise dimensions, how do you ensure that?
We take site measurements or work from engineering drawings, and machine each section in the workshop to spec, so duct fits precisely with the planned layout.
Do fabricated ducts need thermal insulation after installation?
That depends on the system design and which areas the duct passes through, and a site visit confirms whether and what type of insulation is needed.
