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
Tabah is an emerging residential district with mid-rise apartment blocks, hotels and clinics, most of whose modern projects are designed with complex central AC systems needing duct with multiple direction changes and distribution vents across many floors. Site-cut duct cannot meet the required precision or produce complex fittings, so workshop fabrication from G90 galvanized or aluminium sheet delivers high quality and strict dimensional compliance.
Tabah sits in new north Jeddah, a modern building area with residential towers, hotels and advanced commercial projects.
Central AC systems in modern Tabah projects need complex ductwork with multiple bends and distribution vents across many floors.
The AC setup in Tabah
- 1
Complex central duct with bends and distribution vents
Modern Tabah projects require complex duct with multiple bends and distribution vents across many floors to serve residential towers and hotels.
- 2
Direction changes and offsets to avoid architectural obstacles
Duct requires precise offsets to avoid columns, beams and other pipes running through the upper floors.
- 3
Round and rectangular sections by distribution layout
Main trunk lines are typically round for efficiency, with branches distributing via flatter rectangular ducts that fit into suspended ceilings.

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 workshop-fabricated duct differ from site-cut duct?
Yes, workshop-fabricated duct to precise measurements holds strict dimensions and produces complex fittings accurately, whereas site-cut duct cannot achieve this precision and causes air leakage.
Our hotel project needs duct with many bends, how long does fabrication take?
Time depends on the number of vents, bends and total duct length. Share the drawings or site measurements with us on WhatsApp for an accurate estimate.
Site dust and debris can foul the duct during installation, how do you protect it?
Pre-fabricated duct is transported in protective wrapping and sealed at the ends until final installation to keep dust out.
Do you favour aluminium or G90 galvanized sheet for modern projects?
Both are available to suit project requirements and budget. G90 galvanized is stronger and more economical, whilst aluminium is lighter and easier to install at height.
