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 Faisaliyah is a relatively modern district of spacious villas and tall apartment blocks with advanced architectural layouts, and the central ductwork must run through complex ceiling and wall cavities. Site-cut duct leaves uncontrolled leaks and gaps, but workshop fabrication delivers precise bends and transitions that hold system efficiency, essential for the larger projects here.
Al Faisaliyah sits in central Jeddah, a district of modern villas and apartment blocks with advanced layouts and complex internal spaces.
Most modern villas and apartment blocks in Al Faisaliyah use central AC with rectangular ductwork running through ceiling cavities.
The AC setup in Al Faisaliyah
- 1
Rectangular duct fabricated in workshop
Most modern villas and apartment blocks here use rectangular duct because it fits the spaces between ceilings and drywall walls efficiently.
- 2
Complex transitions and bends
The complex internal spaces in villas and apartment blocks require precisely fabricated takeoffs, bends and offsets.
- 3
Duct from G90 galvanized or aluminium sheet
We choose the material based on system size, pressure and environment; galvanized sheet is stronger for larger systems.

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.
Do you fabricate aluminium or galvanized duct for the modern villas here?
We fabricate both. G90 galvanized sheet is stronger and longer-lasting for large central systems, while aluminium is lightweight for installations needing flexibility.
The ceiling spaces in my villa are complex, can you fabricate duct with bends and takeoffs?
Yes, we fabricate bends, takeoffs, transitions and offsets in the workshop from site measurements or drawings to fit complex spaces exactly.
Heat in Al Faisaliyah is intense, does fabricated duct keep the system efficient?
Yes, precise fabrication eliminates air loss at joints, so duct keeps the cooled air intact with no waste, essential in this hot climate.
How do you deliver the fabricated duct to job sites in Al Faisaliyah?
We deliver duct in a covered truck, and the team lifts it directly from the vehicle to the installation space in the overhead cavities.
