Horizontal Rod
Horizontal Rod, often called Ledgers, are essential components that connect vertical standards in the Cuplock scaffolding system. They don’t just link the structure together—they shape the entire working platform, creating strong and level surfaces for workers and materials.
Engineered from high-strength steel, these bars ensure excellent stability and load distribution across the scaffold. Thanks to the clever cuplock locking mechanism, installation and dismantling are fast and secure, saving valuable time on site.
Available in a wide range of lengths, Horizontal rod can easily adapt to different project layouts, whether you’re building straight runs, corners, or irregular shapes. Their hot-dip galvanized finish provides long-lasting protection against rust and harsh weather conditions.
- Lengths available: 0.6m / 0.9m / 1.2m / 1.5m
- Finish options: Hot-dip galvanized or painted

Q
What is a Cuplock Scaffolding System?
A Cuplock scaffolding system is a modular steel scaffold structure featuring unique cup-joint connections. It allows fast, secure assembly using vertical standards, horizontal ledgers, braces, and other components.
Q
What is the load capacity of the Cuplock system?
Each vertical leg can typically support ≥ 40 kN (approximately 4 tons), depending on spacing, layout, and support conditions. All components are tested to meet EN12810 and BS1139 standards.
Q
What certifications does your scaffolding comply with?
Our Cuplock scaffolding meets international standards such as:
- EN12810 / EN12811 (Europe)
- BS1139 (UK)
- AS/NZS (Australia/New Zealand)
Q
Is Cuplock suitable for curved or irregular building designs?
Yes! Cuplock’s modular design easily adapts to curved façades, circular structures, and complex layouts by adjusting ledger and brace configurations.
Q
Can I purchase individual parts instead of a full set?
Absolutely. We sell both complete systems and individual components, helping you replace worn-out parts or expand your existing inventory.
Q
What surface treatments are available for Cuplock components?
Cuplock components typically undergo hot-dip galvanizing to provide heavy duty corrosion protection (up to 120μm thickness). Spray painting and electro-galvanizing options are also available based on specifications.
