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
Dhahban is a coastal area in far north Jeddah featuring luxury villas, hotels and resorts near the sea. The harsh coastal environment with high humidity and sea salt demands duct made from corrosion-resistant materials with extra protection. Central systems here are complex and distributed across many floors, so ductwork must be workshop-fabricated with high precision using special protective materials and coatings.
Dhahban sits in far north coastal Jeddah, an area of luxury villas and hotels directly near the sea.
Projects here use central ductwork in corrosion-treated aluminium or galvanised steel with additional protective coatings against sea corrosion.
The AC setup in Dhahban
- 1
Central ductwork in protected aluminium or galvanised steel
Beachfront hotels and resorts use central ductwork treated against sea corrosion, with extra protective coating and thick thermal insulation.
- 2
Fully insulated duct to prevent condensation and corrosion
High coastal humidity requires thick external thermal insulation around all duct sections to prevent moisture condensation and corrosion.
- 3
Duct with condensate drainage for heavy humidity
Beachfront villas and hotels may need additional condensate drain systems to handle water from high humidity levels.
Before the visit
Before our visit in Dhahban

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.
Sea salt can corrode duct fast, how do you protect it?
We use pure aluminium or heavily rust-treated G90 galvanised steel. We add extra protective coating and external thermal insulation for double protection in the coastal environment.
High humidity causes heavy condensation, how do you solve it?
Duct is wrapped with thick external thermal insulation to prevent moisture condensation. We also recommend an additional condensate drain system for heavy condensation.
Does the duct withstand strong winds on exposed roofs?
Yes, aluminium and galvanised steel are robust, but exposed roofs need strong fixing and extra insulation. We recommend periodic checks to monitor fastening and coating condition.
Coastal projects can take time, can you speed up fabrication?
Yes, if you provide complete drawings and measurements upfront, we can fabricate quickly and deliver to the project schedule.
