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 Rehab is a central district with mid-range apartment blocks, hotels, clinics and shopping centers, whose conventional modern construction allows moderately complex central AC systems with limited-bend duct and distribution vents across several floors. The central location and moderate construction means workshop-fabricated duct with high craftsmanship delivers reliable performance for many years, avoiding on-site cutting and assembly problems.
Al Rehab sits in central Jeddah, a balanced residential and commercial district with mid-rise buildings and diverse urban services.
Central ductwork systems in Al Rehab need moderate complexity with limited bends and efficient distribution across several floors.
The AC setup in Al Rehab
- 1
Central duct at moderate complexity level
Al Rehab projects need duct with limited bends and effective distribution vents across several floors to cover residential towers and hotels efficiently.
- 2
Mix of rectangular and circular sections by available space
Duct combines rectangular sections in suspended ceilings with circular pipes in main trunks to balance efficiency and available space.
- 3
Precise joints and calculated offsets
Every offset and bend is fabricated precisely to ensure no air leakage and efficient distribution to all vents.

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.
Our mid-range project, is workshop-fabricated duct worth the cost compared to site cutting?
Yes, fabricated duct maintains precise dimensions and greatly reduces air leakage, delivering better efficiency and performance for many years, and the extra cost is offset by long-term system efficiency.
Al Rehab is central, is aluminium or galvanized better here?
Both suit well; galvanized is stronger, more economical and more common, whilst aluminium is lighter if there are weight constraints.
Can you fabricate duct from engineer drawings or from site measurements?
Yes, we accept complete engineering drawings or take full site measurements and fabricate duct based on what you provide.
How long does fabrication and site delivery take?
Time depends on project scope and duct complexity; share drawings or measurements with us on WhatsApp for an accurate estimate.
