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 Harazat is an industrial and commercial district with large buildings and vast internal spaces, and the factories, warehouses and retail stores here need ductwork with large diameters, long runs and robust branches. These projects are too big and complex for on-site cutting, and workshop fabrication delivers precision, strength and fast installation. Industrial dust and intense east Jeddah heat demand airtight, robust duct, and heavy-gauge galvanized and aluminium provide this with high efficiency.
Al Harazat is in east Jeddah, an industrial and commercial district of warehouses, factories and large retail stores.
Most projects here have vast open spaces needing duct of 600 to 1200 mm diameter and long runs, and workshop fabrication ensures it handles heavy loads and maintains airtight seals.
The AC setup in Al Harazat
- 1
Large-diameter duct with long runs
Factories and warehouses in Al Harazat need duct over 600 mm diameter with runs reaching tens of metres to distribute air across vast spaces.
- 2
Heavy-gauge galvanized for load bearing
Large duct needs thick, robust material to bear its weight and air pressure, and heavy-gauge galvanized delivers this with high corrosion resistance.
- 3
Robust complex branches and transitions
Large ductwork networks need multiple robust branches and complex transitions to distribute air efficiently, which the workshop fabricates with high precision.
Before the visit
Before our visit in Al Harazat
- 1
Get complete architectural drawings of the space
Complete drawings help us understand vast spaces and existing obstacles before taking large-scale on-site measurements.
- 2
Confirm lifting and transport equipment can access the site
Large duct needs heavy equipment for installation, so ensure the factory or warehouse permits safe access for lifting gear and transport vehicles.
- 3
Mark all pipe, drain and obstacle locations
Tell us where all pipes, drains, structural supports and other obstacles are so we design the duct route without clashes or field modifications.

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.
Huge warehouses and factories need very strong duct, can fabricated duct handle it?
Yes, we use heavy-gauge galvanized or robust aluminium as needed, and workshop-fabricated duct is tested before delivery to ensure it handles high loads and pressures.
Large diameters of 600 mm or more, can they be installed easily in warehouses?
Large duct needs precise installation planning, and workshop fabrication with exact lengths and shapes fits existing structures and supports without modification.
Does industrial dust and heat damage galvanized duct?
Heavy-gauge galvanizing resists dust, moisture and heat, and airtight workshop sealing of joints keeps dust out and maintains efficiency.
Drains and sewage pipes in factories and warehouses, how do they not clash with large duct?
We survey the internal spaces and foundations thoroughly before fabrication and map the duct route precisely to avoid all pipes and drains safely.
