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
Madinat Al Sultan mixes small and medium industries with distribution warehouses, and cooling needs vary by site due to different activities and floor areas. Some sites may need simple straight duct, others need complex branches and sharp bends. On-site cutting is inefficient with this variety, but workshop fabrication gives flexibility and precise fit to each factory or warehouse's needs.
Madinat Al Sultan in south Jeddah is a mixed industrial zone with diverse small and medium factories and distribution warehouses.
Industries in Madinat Al Sultan are diverse, so cooling systems range from small to medium central units with ductwork tailored to each case.
The AC setup in Madinat Al Sultan
- 1
Small to medium central duct systems
Small and medium industries here need central cooling from simple to moderately complex, with duct sized to the site.
- 2
Flexible branches to match each site's needs
Each site may need different branches to match production or storage layout, and we fabricate them precisely to your specific needs.
- 3
Flat duct for low ceilings and tight spaces
Many warehouses in the area have low ceilings or tight spaces, so we assess each case and fabricate duct that fits the site constraints.
Before the visit

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 factory is small, do you fabricate economical duct for small spaces?
Yes, we fabricate duct systems for any size, from small to large, to suit your needs and budget, without compromising quality or precision.
Our warehouse is divided into different sections, how do you cool each section?
We fabricate separate branches for each section as you need, allowing independent airflow control to each area if required.
Space is tight and ceilings might be low in places, does this affect the duct?
We fabricate flat or rectangular duct that adapts to low ceilings and tight spaces, maintaining reliable cooling performance.
Can you modify the duct later if we expand operations?
Pre-fabrication makes future additions or changes easy, so we can add new branches or expand the duct to match your growth without rebuilding.
