Cuplock scaffolding is a modular system scaffold widely used in construction, infrastructure, and industrial projects. It adopts a unique cup-and-lock joint connection, which allows quick fastening of ledgers and braces to the vertical standards without the need for bolts or loose fittings. This simple locking mechanism ensures fast installation, high strength, and excellent stability.
The system is designed with standardized modular components including verticals, ledgers, diagonal braces, base jacks, U-head jacks, steel planks, guardrails, and toe boards. The 500mm interval cup joints on the standards provide flexible height adjustment and versatile combinations for different structures.

Description |
| Vertical (Standard) | 500 / 1000 / 1500 / 2000 / 2500 / 3000 | #48.3 × 3.2 / 3.25 | With top and bottom cup joints, spacing every 500mm |
| Ledger (Horizontal) | 500 / 1000 / 1250 / 1500 / 2000 / 2500 | #48.3 × 3.0 / 3.25 | Both ends with forged blade, locked into cup joint |
| Diagonal Brace | 1500 / 2000 / 2500 / 3000 / 4000 | #48.3 × 3.0 | With swivel blade at both ends for bracing |
| Adjustable Base Jack | 500 / 600 | #38 / #48 threaded screw | For height adjustment at the bottom of verticals |
| Adjustable U-Head Jack | 600 / 750 | #38 / #48 threaded screw | For supporting beams or formwork at the top |
| Steel Plank | 210×45×1000/1500/2000/3000 | Steel sheet 1.2-1.5mm | With anti-slip holes and hooks |
Our cuplock scaffolding features high-strength vertical standards with cup joints every 500mm for flexible assembly; horizontal ledgers with precision forged blade ends for quick connection; and diagonal braces for strong structural support. Adjustable base jacks allow easy height leveling, while U-head jacks support beams and formwork.
Quick and Easy Assembly: Simple cup-and-lock joint design allows fast erection and dismantling without bolts, saving labor and time.
High Load Capacity: Each vertical can carry 40-60kN, suitable for high-rise buildings and heavy-duty projects.
Durable Surface: Hot-dip galvanized surfaces ensure long service life with minimal maintenance.
Frame scaffolding involves raw material preparation, cutting, forming, welding, surface treatment, inspection, and packaging. Q345B or Q235B steel is cut and formed into components, welded precisely, then hot-dip galvanized or coated for corrosion protection. After quality checks on dimensions, welds, and load capacity, parts are bundled for shipment.
