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 Rawasi is an eastern district with medical facilities, clinics and laboratories alongside modern mid-rise residential buildings, where healthcare buildings especially demand leak-free AC systems at high cleanliness standards because any air escape can lead to indoor contamination. On-site duct fabrication exposes the work to uncontrolled conditions and risks seal quality, whereas workshop manufacture provides a controlled environment ensuring every joint is tight and gap-free.
Al Rawasi sits in Jeddah's eastern sector, a district of medical facilities and clinics mixed with modern residential buildings.
Medical buildings in Al Rawasi typically use round aluminium or rectangular galvanised steel duct for central AC and air purification systems.
The AC setup in Al Rawasi
- 1
Clean round duct for clinics and laboratories
Medical buildings in Al Rawasi typically use round duct for air purification systems, as the circular profile reduces turbulence and maintains cleanliness better than rectangular designs.
- 2
Rectangular with no weak joints for large facilities
Larger hospitals and medical centres choose rectangular duct with extremely tight joints, since even minute leakage can affect indoor air purity.
- 3
Galvanised steel resistant to humidity and mould
Al Rawasi is relatively humid due to its proximity to the coast, so we use galvanised steel which resists corrosion and mould better than aluminium.
Before the visit
Before our visit in Al Rawasi
- 1
Get approval from the medical building management
Ensure the clinic or hospital management is informed of the visit time and grants access to engineering routes without disrupting patients.
- 2
Assess the condition of engineering routes and suspended ceilings
Inspect the passages and suspended ceilings before our visit to ensure they are safe and able to support the weight of new ductwork.
- 3
Prepare safe access point for the team
Designate a safe route outside clinical corridors or treatment areas so our team can access easily without interfering with medical operations.

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.
Does fabricated duct meet cleanliness requirements for clinics and hospitals?
Yes, we fabricate in a clean workshop with tight sealed joints that prevent air leakage, stopping contaminant and mould intrusion, which is exactly what medical standards demand.
Medical buildings are crowded with equipment, how do you access the service routes?
We coordinate with the medical building management before the visit to gain authorised access to passages and suspended ceilings without disturbing patients and staff.
Humidity and airborne mould affect duct, how do you address this?
We select mould-resistant materials and slope the duct slightly for drainage, while tight joints block external humidity entry that would feed mould growth.
Do refrigerant lines and drain pipes cross or interfere with the ductwork?
We fabricate the duct with pre-made openings for refrigerant lines and drain pipes to pass through, keeping joints sealed tight around these apertures to stop any air escape.
