Documentation & Knowledge Base

Cuplock is a modular scaffolding system that uses a top-cup / bottom-cup node mechanism welded to vertical standards at fixed 500 mm intervals. A single hammer-tap engages all four perpendicular members (ledgers or transoms) at once, making it faster to erect than tube-and-fitting or wedge-pin systems. SCAFFWORKS manufactures cuplock components from EN10219 cold-formed welded structural steel at our UAE facility. See the cuplock system datasheet for full component dimensions.

Our standards and ledgers use EN10219 cold-formed welded structural steel tube, grade S235JR or S275JR. Outside diameter is 48.3 mm with 3.2 mm wall thickness (3.0 mm available on request). S355JR is available for high-load applications. See the EN10219 datasheet for full material properties.

Rental is typically priced per tonne of scaffolding per month, with separate handling for erection and dismantling labour. Pricing varies with project duration, site complexity, transport distance from our Umm Al Quwain facility, and whether the package is supply-only or includes erection.

Yes. Our in-house engineering team prepares site-specific scaffolding and shoring designs, load calculations, and method statements for UAE construction projects. We work to BS 1139, BS 5975, and EN 12810/12811 where applicable. Contact us with your project drawings and we will provide a design proposal.

We supply, rent, and deliver scaffolding and formwork across Dubai, Sharjah, Ajman, Umm Al Quwain, and Ras Al Khaimah. Manufacturing and the main yard are based in Umm Al Quwain. Projects in Abu Dhabi and Al Ain are reviewed on a project-by-project basis depending on transport logistics.

Ask for three things: (1) the mill certificate (EN 10204 type 3.1 or 3.2) showing chemical and mechanical properties for the heat number on your delivery; (2) traceable heat-number marking on individual tubes; (3) any recent independent test reports confirming load capacity. Spot-check incoming tube wall thickness with a digital caliper — this is the most common place commodity scaffolding fails to match its claim. See the EN10219 datasheet for the full verification checklist.

Yes, significantly. A scaffold leg's allowable load is limited by buckling, not by steel yield strength. Doubling jack extension roughly halves capacity. A fully retracted leg may carry ~45 kN, but at 600 mm of total extension (base + U-head) capacity drops to ~11 kN. Keep total extension under 300 mm where possible. See the jack load tables for the full capacity curve.
