The UAE's industrial base, built on oil and gas infrastructure, large-scale construction, power generation, and maritime activity, runs on fabricated metal. Tanks, pipelines, boilers, steel drums, steam generators, and structural metalwork are foundational to how that infrastructure operates. And like all physical assets, they need to be repaired. According to Mobility Foresights, the UAE metal fabrication market was valued at USD 8.65 billion in 2024 and is projected to reach USD 13.72 billion by 2031, growing at a CAGR of 6.7%.[1] The UAE's National Infrastructure Development Programme has committed USD 122 billion to transportation, energy, and urban development, with each of those projects generating metal assets that will require ongoing repair and maintenance for decades to come.[2]
Activity 3311.00 sits directly in that opportunity. It licenses the repair and maintenance of fabricated metal products, carried out through welding, platework, and component restoration, whether in a fixed workshop or on-site via mobile operations. The combined Saudi Arabia, UAE, and Qatar welding market, which underpins this type of work, was valued at USD 470.1 million in 2024 and is forecast to reach USD 673.5 million by 2030 at a CAGR of 6.3%, with oil and gas alone accounting for over half of all demand.[3] For technically capable operators, this is a license backed by one of the most capital-intensive and maintenance-dependent industrial landscapes in the world.

Who Is This Activity For?
INDUSTRIAL SERVICES
SPECIALIST TRADE
MANUFACTURING SUPPORT
Industrial Maintenance Contractors Engineering and maintenance firms serving oil and gas, power generation, and heavy industry clients who require certified repair services for pipelines, pressure vessels, boilers, and structural metalwork as part of long-term asset maintenance contracts.
Welding & Metalwork Specialists Qualified welders, platework specialists, and mobile welding operators who wish to establish a licensed entity in the UAE to offer on-site and workshop-based metal repair services to construction, marine, and industrial clients across the emirates.
Manufacturing & Workshop Operators Companies operating metal fabrication workshops that want to expand into the repair and refurbishment segment, offering services such as drum reconditioning, tank repair, and structural steel maintenance to complement their existing production capabilities.
3311.00 - Repair of Fabricated Metal Products
Activity code 3311.00 covers the repair and maintenance of fabricated metal products as classified under Division 25 of the ISIC framework. Division 25 encompasses metal products that are primarily static or structural in function (tanks, containers, pipelines, boilers, structural steelwork, and ordnance) as distinct from machinery or equipment that incorporates moving parts.
The repair activity in 3311.00 therefore deals with restoring the physical integrity, structural soundness, and operational fitness of these static metal items, through techniques such as welding, platework, pressure testing, surface restoration, and component replacement. The activity covers both workshop-based repair and on-site mobile operations, meaning licensees may operate a fixed facility, attend client locations, or both.
Repair of Metal Tanks, Reservoirs & Containers
Repair & Maintenance of Pipes and Pipelines
Mobile Welding Repair
This sub-type covers the structural and surface repair of metal tanks, reservoirs, and storage containers used across industrial, commercial, and logistical applications. Work includes inspecting and repairing weld seams, treating corrosion, sealing leaks, restoring structural panels, and recertifying containers for continued service. In the UAE, demand is particularly strong from the oil and gas, chemical storage, and water infrastructure sectors, where metal tanks form a critical part of asset inventories and must meet strict safety and compliance standards.
This sub-type covers the repair, maintenance, and integrity restoration of metal pipe systems and pipeline segments, including above-ground and in-plant pipework used in industrial facilities. Services include weld repairs, pipe section replacement, flange repair, joint integrity work, and anti-corrosion treatment. The UAE's extensive oil, gas, and water infrastructure creates consistent and well-funded demand for this service. With the UAE's National Infrastructure Development Programme committing USD 122 billion to energy and transport infrastructure, pipeline repair specialists are well-positioned to serve both government and private sector clients.
Mobile welding repair involves deploying welding technicians and equipment directly to client sites to carry out on-the-spot structural and fabrication repairs without the need to remove or transport the item to a workshop. This is particularly valuable on construction sites, industrial plants, ports, and remote facilities where components cannot easily be moved. Mobile operators typically carry arc, MIG, TIG, and oxy-fuel welding equipment, and may be called upon to repair structural steel frames, metal supports, pipework, access equipment, and fabricated components in situ. The rapid growth of construction activity in the UAE, with over 13,000 active construction projects in Dubai alone, sustains strong demand for responsive mobile repair services.
Repair of Steel Shipping Drums
Repair & Maintenance of Steam Generators, Boilers & Auxiliary Plant
Repair & Maintenance of Firearms & Ordnance
Steel shipping drums used for the transport and storage of chemicals, lubricants, industrial fluids, and food-grade products require periodic inspection, reconditioning, and repair to remain fit for purpose and compliant with transport regulations. This sub-type covers the cleaning, dent removal, weld repair, re-lining, lid replacement, and recertification of steel drums. In the UAE, the chemicals, oil and gas, and food processing industries generate consistent demand for drum reconditioning services, supported by the country's role as a major trade and re-export hub through Jebel Ali Port.
This sub-type covers the repair and ongoing maintenance of steam generators, vapour generators, and their associated auxiliary equipment, including condensers, economizers, superheaters, steam collectors, and accumulators, as well as marine and power boilers, and nuclear reactor components (excluding isotope separators). These are high-value, safety-critical assets found in power stations, desalination plants, industrial manufacturing facilities, and marine vessels. Repair work in this segment demands specialist certifications and adherence to pressure equipment regulations, and typically operates within structured maintenance contracts.
This sub-type covers the repair and maintenance of firearms and ordnance, including sporting and recreational guns, as defined under Division 25's scope for the manufacture and maintenance of weapons and ammunition. Work in this area is strictly regulated in the UAE and requires specific licensing and compliance approvals from relevant authorities beyond standard trade licensing. Eligible operators typically serve licensed shooting clubs, law enforcement procurement chains, and authorised sporting firearms dealers. This is the most narrowly scoped and compliance-intensive sub-type within 3311.00.
Activity code 3311.00 has clear boundaries around what it does not cover. The repair of central heating systems falls under a separate classification and is explicitly excluded, as is the repair of mechanical locking devices and safes. More broadly, the activity is restricted to Division 25 fabricated metal products, meaning any repair work on machinery or equipment that incorporates moving parts sits outside its scope.
In short: if the item is a fabricated metal product such as a tank, pipeline, drum, boiler, or structural metal component, and you are repairing or maintaining it, you are in. If the item is a central heating system, a locking device, or a safe, you are not.
