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 Rahmah contains specialist clinics, dental surgeries and a small health centre, all requiring strict control of air quality and temperature for health reasons. Duct fabricated to very high precision with sealed joints is essential to minimise contaminated-air leakage and ensure uniform, clean air distribution. In Al Rahmah's hot, humid climate, internally protected duct prevents moisture and dust ingress that could compromise patient safety and medical equipment.
Al Rahmah lies in south Jeddah, a district of specialist clinics and small health centres with high standards for air-quality monitoring.
Medical facilities in Al Rahmah require duct to very high specifications and tight joints to ensure no contaminants enter sensitive areas.
The AC setup in Al Rahmah
- 1
Sealed duct to medical specifications
The duct is fabricated with very tight joints and an internal protective layer to ensure no contaminated air leaks into sensitive areas.
- 2
Medium diameters with precise distribution
Clinics do not need large diameters but require precise distribution of clean air across treatment and reception rooms.
- 3
Metal with moisture-resistant protective layer
We use metals with a special internal protective layer that prevents moisture and mould accumulation in the hot, humid climate.

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.
My clinic needs uniform clean air, does fabricated duct provide this?
Yes, duct fabricated to very high precision with tight joints minimises contaminated-air leakage and ensures uniform clean air distribution across all clinic rooms.
The clinic's entrance is narrow, can you deliver the duct easily?
We fabricate the duct in assembly-ready sections so it fits through the narrow entrance, then assemble it on site to exact specifications with no air loss.
Humidity and heat affect patient safety, does the duct protect against this?
We use metal duct with tight joints and an internal protective layer that prevents moisture and dust entry, maintaining the required air quality and temperature.
My hospital is being upgraded, how do you handle interim drawings?
We work from interim drawings and visit the site to verify final measurements. If changes occur, we fabricate additional duct easily without delaying the project.
