If your BOQ says “JASCO,” you are looking at pipe from a Jeddah steel mill — not an import brand, and not the similarly-named companies this guide will help you tell apart. JASCO (Al-Jazera Factories for Steel Products) has manufactured steel pipe in Jeddah since 1988, and its ERW and galvanized pipes are a staple of fire fighting, plumbing, and HVAC packages across Saudi Arabia.
This guide covers what JASCO makes, the standards and sizes that matter for your specification, where JASCO pipe is used, and — importantly — how to make sure the “JASCO” on your submittal is the right company.
JASCO vs Jazeera Steel vs Mabani Al Jazeera: Know the Difference
Three similar names, three different companies. Getting this right matters because mill certificates, approvals, and submittals are issued in the manufacturer’s legal name:
- JASCO — Al-Jazera Factories for Steel Products Co., Jeddah, Saudi Arabia. The manufacturer. Established 1988, producing steel pipes and tubes in Jeddah with a licensed annual capacity of 260,000 metric tons of pipes, tubes, and sheets. When a Saudi BOQ says “JASCO,” this is the company it means.
- Jazeera Steel — Oman. A different company, an Omani steel producer. Not JASCO, not affiliated with JASCO.
- Mabani Al Jazeera — a trading company. Not a manufacturer. Different company entirely.
Practical rule: check the full legal name on the mill test certificate, not just the short brand on the quotation. If the certificate says Al-Jazera Factories for Steel Products, Jeddah — you have JASCO.
The Mill: Al-Jazera Factories, Jeddah
JASCO was established in 1988 in Jeddah to manufacture steel pipes and tubes for the Saudi domestic market and export, and has grown into one of the Kingdom’s main steel pipe producers. Its licensed production capacity reaches 260,000 metric tons per year across pipes, tubes, and sheets.
For Saudi buyers, a Jeddah mill means two practical advantages: short supply chains to projects in Jeddah, Makkah, and Madinah, and ex-stock availability through Riyadh stockists like Ajal Arabia for the rest of the Kingdom — without the lead times and freight exposure of imported pipe.
Why a Saudi Mill Matters for Saudi Projects
There is a quiet advantage to pipe made in the Kingdom, and it has nothing to do with patriotism. First, lead time: a Jeddah mill ships to a Jeddah or Makkah site in days, and Riyadh stockists hold JASCO pipe ex-stock for the rest of the country — compare that with the 8–12 week mill rolling cycles of imported pipe. Second, submittal familiarity: consultants across Saudi Arabia have seen JASCO mill certificates for decades, which means fewer queries and faster approvals. Third, project alignment: Saudi giga-projects and Aramco-area work increasingly favor local content and local manufacturing; sourcing pipe from a Jeddah mill keeps your procurement story clean. When your program is tight, “made in Jeddah, stocked in Riyadh” beats “on the water” every time.
What JASCO Makes: Standards & Sizes
JASCO’s core range is ERW (electric resistance welded) steel pipe and tube, in black and galvanized finishes, alongside pre-galvanized tubular products, commercial tubes, and square/rectangular hollow sections. Key facts for specifiers:
- Sizes: 1/2″ to 6″, with wall thicknesses up to 7.20 mm
- Standards: ASTM A53 (Grades A & B), BS 1387, ANSI C80.1, EN 10255 / EN 10219
- Quality system: ISO 9001
- Sectors served: oil & gas, petrochemical, water transmission, agriculture, and construction
JASCO’s company profile lists approvals including Saudi Aramco, SASO, UL, and FM. As with any listed product, approvals and listings evolve — confirm the current certificates against your project’s submittal requirements before ordering, and ask your supplier to provide them with the quotation.
JASCO Welded Pipe: Types Ajal Arabia Supplies
From the JASCO range, Ajal Arabia supplies the three welded pipe configurations Saudi MEP BOQs call for:
- Black welded pipe, plain ends — the standard for fire fighting sprinkler systems (black steel ERW Schedule 40 to NFPA 13) and closed-loop HVAC/chilled water lines
- Galvanized welded pipe, plain ends — for potable water, exposed exterior runs, and anywhere corrosion resistance matters
- Galvanized threaded pipe with couplings — ready-to-install screwed pipe for plumbing and small-bore fire protection branches
Because JASCO pipe is produced to ASTM A53, it slots directly into specifications written around that standard — no equivalency arguments, no submittal friction.
JASCO Seamless Pipe
In addition to its welded range, JASCO is among the seamless pipe brands Ajal Arabia supplies. If your line list calls for seamless pipe under the JASCO brand, share your grades, sizes, and quantities and we will confirm availability and mill certification — with EN 10204 3.1 mill test certificates to support your submittal, as with all our seamless supply.
Where JASCO Pipe Is Used on Saudi Projects
- Fire fighting systems — black ERW pipe for sprinkler mains, hydrant networks, and risers (confirm listing requirements with your specification)
- Plumbing — galvanized pipe for domestic water distribution in residential and commercial towers
- HVAC — chilled water and condenser water circuits, particularly in Jeddah and Makkah region projects served directly from the mill
- Construction and scaffolding — commercial tubes and scaffolding pipe
- Water and agriculture — galvanized and black pipe for irrigation and water transmission
Specifier’s Checklist for JASCO Pipe
- Confirm the manufacturer — mill certificate must read Al-Jazera Factories for Steel Products, Jeddah (not Jazeera Steel, not a trader).
- Nominate the standard — ASTM A53 Grade A or B for most MEP work; BS 1387 where the specification calls for it.
- Set size and wall — 1/2″ to 6″, wall up to 7.20 mm; Schedule 40 as the everyday standard for fire fighting and HVAC.
- Choose the finish — black for fire fighting and closed-loop HVAC; galvanized for potable water and exposed service; threaded with couplings where screwed joints are specified.
- Check listing requirements — where the project requires UL/FM-listed pipe, confirm the current listing certificates before ordering.
- Demand MTCs — mill test certificates with heat-number traceability, confirmed before delivery.
- Use the local advantage — Jeddah-mill origin means short lead times; confirm ex-stock availability in Riyadh for Kingdom-wide delivery.
Frequently Asked Questions
Is JASCO the same as Jazeera Steel?
No. JASCO is Al-Jazera Factories for Steel Products, a pipe manufacturer in Jeddah, Saudi Arabia, established in 1988. Jazeera Steel is a separate Omani producer, and Mabani Al Jazeera is a trading company. They are three different companies — verify the full legal name on the mill certificate.
What standards do JASCO pipes meet?
JASCO manufactures to ASTM A53 (Grades A & B), BS 1387, ANSI C80.1, and EN 10255/EN 10219, under an ISO 9001 quality system. Its company profile also lists approvals including Saudi Aramco, SASO, UL, and FM — confirm current certificates against your submittal requirements.
What sizes of pipe does JASCO produce?
JASCO produces steel pipes from 1/2″ to 6″ with wall thicknesses up to 7.20 mm, covering the sizes used across fire fighting, plumbing, HVAC, and construction applications in Saudi Arabia.
Can JASCO pipe be used for fire sprinkler systems?
Yes — black steel ERW pipe to ASTM A53 is the industry-standard choice for wet sprinkler systems to NFPA 13 across Saudi Arabia. Where your specification requires listed pipe, confirm the current UL/FM listing certificates for the sizes you are ordering before placing the order.
