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.
| Component | Common Sizes (mm) | Tube Diameter & Thickness (mm) | 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 thick | With anti-slip holes and hooks, loading ≥250kg/m² |
Cuplock scaffolding features a quick and easy assembly with its simple cup-and-lock joint design, allowing fast erection and dismantling without the need for bolts or loose fittings, saving both labor and time. It offers high load-bearing capacity, with each vertical able to carry 40-60kN, making it suitable for high-rise buildings, bridges, and heavy-duty infrastructure projects.
The system provides strong stability and enhanced safety, as rigid connections between standards and ledgers reduce movement. Its modular design allows flexible height adjustment, while its versatility makes it ideal for shoring, access scaffolding, suspended scaffolding, and formwork support.
Manufacturing involves raw material preparation, precision cutting, forming, welding, and surface treatment. We use high-grade steel (Q345B or Q235B) which is hot-dip galvanized for superior corrosion protection. Our products meet international standards including EN12810/EN12811, AS/NZS 1576, and ISO 9001. Third-party inspections from SGS, TÜV, and BV are available to ensure compliance with global construction requirements.
