What scaffolding standards are required by Saudi Aramco for plant maintenance?

Saudi Aramco requires scaffolding erected and inspected in accordance with SAES-Q-001 (Criteria for Design and Construction of Concrete Structures) and the more applicable SAEP-302 scaffolding procedures, which reference BS EN 12811-1 (Temporary Works Equipment — Scaffolds) and BS EN 12810 for facade scaffolding. Key requirements include: all tubes to be 48.3mm OD hot-dip galvanised to BS EN ISO 1461, all couplers to be drop-forged steel load-tested to BS EN 74-1, scaffold design by a competent scaffold designer for structures above 4m or in confined plant areas, green scaffolding tags (inspection by a certified scaffolding inspector after erection and after any modification), and working platforms with minimum 600mm clear width with full boarding, toe boards, and double guardrails at 470mm and 950mm height. Gulf Union Ozone supplies tubes, couplers, and system scaffold components meeting these Aramco-referenced standards.

Should I use aluminium or steel mobile towers for Saudi Arabia industrial sites?

For most indoor and sheltered Saudi Arabia industrial maintenance applications — vessel internals, heat exchanger tube cleaning, motor rewinding bays, and warehouse maintenance — aluminium mobile scaffold towers to EN 1004 are preferred because they are approximately 60% lighter than equivalent steel towers, allowing one or two workers to assemble and move them without lifting equipment. Aluminium towers are also corrosion-resistant, important in coastal KSA sites near the Red Sea or Arabian Gulf. Steel mobile towers are preferred for outdoor use in high-wind areas (above Beaufort 5) where the additional mass provides greater stability, and for applications requiring deck loads above the EN 1004 aluminium tower limit of 225 kg per platform. Gulf Union Ozone stocks both aluminium EN 1004 and steel mobile towers, and can advise on the correct specification for your working height and load requirements.

Can Gulf Union Ozone supply scaffolding in bulk for EPC construction projects in KSA?

Yes. Gulf Union Ozone regularly supplies scaffolding tubes, couplers, system scaffold components, and access equipment in bulk quantities for major EPC and construction projects across Saudi Arabia including sites in Jubail, Yanbu, Riyadh, Dammam, Jizan, and NEOM. We can supply project scaffold packages — galvanised tubes, right-angle couplers, swivel couplers, sleeve couplers, base plates, base jacks, U-head jacks, and decking boards — in quantities from 100 tonnes to full project requirements. Ringlock and Cuplock modular scaffold systems for large industrial scaffolding contracts are also available.

Type 01

Scaffolding Tubes & Couplers

Scaffolding tubes in 48.3mm OD × 3.2mm wall hot-dip galvanised steel to BS EN 39 and BS EN ISO 1461 — the standard tube specification referenced by Saudi Aramco SAES-Q-001 and all major KSA EPC contractors. Available in lengths 1.0m, 1.5m, 2.0m, 2.5m, 3.0m, 3.5m, 4.0m, 4.5m, 5.0m, 6.0m, and 6.4m. Right-angle couplers (fixed couplers) to BS EN 74-1 — drop-forged steel, hot-dip galvanised, load-tested to 6.1 kN slip resistance — for connecting tubes at 90° in ledgers and transoms to standards. Swivel couplers to BS EN 74-1 for angled connections and diagonal bracing. Sleeve couplers (joint pins) for extending tube lengths end-to-end. Putlog couplers for connecting single-tube putlogs to horizontal ledgers in facade scaffolding. Base couplers for connecting ledger tubes to adjustable base jacks. All couplers drop-forged steel with bolt-type closure for positive locking.

Type 02

Base Plates, Sole Boards & Jacks

Fixed steel base plates 150mm × 150mm × 5mm with welded spigot for tube insertion — for distributing scaffolding load onto solid ground or concrete slabs. Screw adjustable base jacks in 300mm, 450mm, and 600mm extension range — 38mm or 48mm OD spindle, plate 150mm × 150mm — for levelling scaffolding on uneven ground and slopes common on Saudi Arabia construction sites and refinery grade changes. Load capacity up to 50 kN per jack. U-head (fork head) jacks for supporting horizontal beams and soldier props on shoring and falsework assemblies — 300mm and 450mm extension, 50 kN capacity. Timber sole boards (scaffold boards) 225mm wide × 38mm thick in 1.8m and 3.6m lengths for distributing base plate loads on soft or sandy ground — important for desert and coastal KSA sites where bearing capacity is limited. Castors (scaffold wheels) in 150mm and 200mm diameter, swivel and fixed types with braking lock, for mobile scaffold bases.

Type 03

Aluminium Mobile Scaffold Towers

Single-width aluminium mobile scaffold towers complying with EN 1004-1 Class 3 — platform dimensions 0.75m × 1.8m, available in working heights from 2m to 8m in 2m bay increments. Double-width towers with 1.35m × 1.8m platform for heavier duty maintenance and inspection, working heights from 2m to 12m. Stairway access towers (stair-climbing ladder inside tower bay) for sites where vertical ladder climbing is prohibited by the project HSE plan — increasingly specified on Aramco and SABIC shutdowns. All towers assembled with snap-lock (Snap-Fit) or rung-slot frame design without loose fittings — quick assembly, no separate pins or bolts to lose on site. Platform decks are aluminium with anti-slip mesh surface, trapdoor access, and integrated guardrail posts and outriggers. Maximum platform load: 225 kg (personnel + tools). Outriggers (stabilisers) supplied for heights above 3.2m as required by EN 1004. Complete tower kits supplied in stackable aluminium frames for ease of transport and storage on KSA project sites.

Type 04

Steel System Scaffolding (Ringlock & Cuplock)

Ringlock (rosette) modular system scaffolding — the preferred system scaffold for large-area industrial scaffolding in Saudi Arabia oil and gas facilities. Standards (verticals) in 48.3mm OD galvanised steel with pre-welded 8-hole rosette plate at 500mm vertical intervals — compatible with leading European scaffold system manufacturers. Ledgers with pressed-steel wedge-head ends that lock into rosette without tools and with a single hammer blow. Transoms for platform support. Diagonal braces for lateral stability. Working load class 4 (3.0 kN/m² platform load) and class 5 (4.5 kN/m²) for heavy-duty heat exchanger bundle pulling and equipment maintenance platforms. Cuplock (cup-and-blade) system scaffolding — widely specified and stocked for KSA turnaround scaffolding work. Top cup and bottom cup (spigot cup) in hot-dip galvanised steel for fast assembly and dismantling during tight shutdown windows. Ringlock and Cuplock components compatible with standard 48.3mm tube-and-coupler accessories.

Type 05

D-rung aluminium extending ladders for general site access and maintenance. Fibreglass (GRP) ladders for electrical work around live panels, switchgear, and overhead lines — non-conductive rails to EN 131 for dielectric safety, available in 3m to 9m standing heights. Step platforms (mobile work platforms) in aluminium with anti-slip treads, handrails on both sides, and four-castored base — working heights 0.5m to 2.0m for access in warehouses, process plant ground-floor areas, and equipment loading bays. Platform ladders (A-frame step ladders) in 4-step to 12-step aluminium with integral platform top for light maintenance. Podium steps (podium safety steps) in aluminium — fully enclosed platform with guardrails on all sides and locking gate, load 250 kg, available at 1.0m and 1.5m platform heights for electrical and instrument panel access without a full mobile scaffold tower.

Type 06

Safety Nets, Debris Chutes & Edge Protection

Scaffold safety nets (personnel protection nets) to EN 1263-1 Type S — knotted and knotless high-tenacity polyethylene mesh nets in 5m × 10m and 6m × 10m panels for catching falling persons and tools from scaffolding. Safety nets to EN 1263-1 Type U (debris nets) for light debris and dust containment on exterior facade scaffolding on Saudi Arabia buildings and process vessels. Debris chutes in HDPE interlocking panels — 45° elbow and straight sections — for channelling construction waste from scaffold working platforms to ground-level skips safely without throwing debris. Scaffold toe boards in 150mm × 25mm pressure-treated timber or aluminium toe board clips and boards, for preventing tools and materials falling from scaffold platform edges. Handrail posts (guardrail posts) in 48.3mm galvanised steel tube, push-fit or clip-on type for attachment to scaffold ledgers — guardrail at 950mm and mid-rail at 470mm above platform.
