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 Mustaqbal is a growing modern district with mid- and high-rise apartment blocks, a large shopping mall and light industrial space, and projects here are usually new with layouts allowing for orderly and complex duct design. Workshop fabrication benefits these major projects by cutting site time, ensuring higher quality and better adherence to engineering drawings, with duct arriving ready and no air loss.
Al Mustaqbal, in south Jeddah, is a growing modern district with tall residential blocks, a major mall and commercial zones.
Modern projects in Al Mustaqbal typically need large-diameter duct with unified systems covering multiple floors or wings from several outdoor units.
The AC setup in Al Mustaqbal
- 1
Unified multi-floor system
Modern projects in Al Mustaqbal need unified duct systems linking multiple outdoor units across many floors, all made to the same precise standards.
- 2
Variable diameters by distribution zones
Main duct is large-diameter splitting into smaller branches by zone or floor, each section made to exact size.
- 3
Tight joints with no leakage
Joints between duct sections are tightly sealed in the shop with no leakage, maintaining system efficiency over its lifetime.
Before the visit
Before our visit in Al Mustaqbal
- 1
Provide engineering drawings and the contractor details
Before the visit, send complete project drawings and contractor and engineer contact details so we can coordinate directly on routes and timeline.
- 2
Precisely mark unit and outlet locations
Confirm the exact location of each outdoor unit and every indoor outlet on the drawings, since this defines duct length and branch count.
- 3
Check vertical and horizontal routes for obstructions
Inspect passages, ceilings and walls where duct will run to ensure no electrical conduits or other pipes conflict with the duct route.

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 handle large mall and apartment projects in Al Mustaqbal?
Yes, we fabricate complete duct systems for major projects, malls, high-rise blocks and commercial complexes, every system made in the workshop from full engineering drawings.
Large duct sections are heavy, how do you transport them to site?
We make duct in transportable sections using appropriate vehicles for safe delivery, and the installation team raises them to ceilings with safe lifting equipment.
Does the fabricated duct match the project's engineering drawings?
Absolutely, we measure precisely from your engineering drawings and fabricate every section to match, and before installation we confirm each section matches the plan.
What if design changes happen during construction?
We can adapt the design and duct quickly if changes occur, measure the new space and fabricate what is needed in the shop without long delays.
