Component dimensions, weights, materials, and working configurations for the cuplock modular scaffolding system manufactured at our UAE facility.
The Scaffworks cuplock system is a modular scaffolding system using a top-cup / bottom-cup node mechanism that locks four blade ends in a single hammer-tap. The system is identical in concept to other cuplock systems worldwide and is fully compatible with industry-standard ledgers, transoms, and accessories.
Standards carry the vertical load down the scaffold. They are made from EN10219 cold-formed welded structural steel tube, with a node cup welded at every 500 mm (the standard cuplock node spacing).
| SKU | Description | Length | Tube OD | Wall thk. | Weight |
|---|---|---|---|---|---|
| STD-100 | Standard 1.0 m | 1000 mm | 48.3 mm | 3.2 mm | 4.64 kg |
| STD-150 | Standard 1.5 m | 1500 mm | 48.3 mm | 3.2 mm | 6.96 kg |
| STD-200 | Standard 2.0 m | 2000 mm | 48.3 mm | 3.2 mm | 9.28 kg |
| STD-250 | Standard 2.5 m | 2500 mm | 48.3 mm | 3.2 mm | 11.60 kg |
| STD-300 | Standard 3.0 m | 3000 mm | 48.3 mm | 3.2 mm | 13.92 kg |
Ledgers tie standards together horizontally and run parallel to the working face. Transoms run perpendicular and support deck planks or formwork beams.

Tube weights are calculated for 48.3 mm OD × 3.2 mm wall EN10219 steel at 7850 kg/m³ steel density, plus an allowance for end-blade and cup hardware. Actual product weights tested at our Umm Al Quwain facility fall within ±3% of the values above.
Every Scaffworks standard has a node assembly at 500 mm intervals (excluding the bottom 250 mm so the lowest node sits at a usable height when base jacks are used). The node consists of:
A single hammer tap on the top cup engages all four perpendicular members simultaneously. This is why cuplock is faster to erect than tube-and-fitting or wedge-pin systems.
For slab shoring, standards are erected on a grid pattern and topped with U-head jacks (forkheads) carrying primary beams. Grid spacing is driven by slab thickness and load, not floor height. Typical configurations:
These are indicative starting grids. The final spacing, standard sizing, and ledger layers are confirmed by a full shoring design — the same basis used by our slab shoring calculator.
For access scaffolds, standards run continuously and ledgers tie at each lift (typically 2.0 m). A working bay is 2.1 m or 2.5 m long with platform widths of 0.9 m (two-plank), 1.2 m (three-plank), or 1.5 m (four-plank).
The system geometry is consistent with the cuplock systems described in BS 1139 Part 3 (compatible scaffolding components). Steel tube conforms to EN10219 S235JR / S275JR. Connection components are forged or cast steel per relevant material specifications. See EN10219 steel tube datasheet for material details.
Scaffolds erected from Scaffworks components must be designed and inspected by a competent person under the responsible contractor's HSE management system, in line with UAE labour law and local emirate-level construction requirements.
