Ringlock Rosette Double Shear Test: Exceeding EN 12811 Standards | FormScaffold

Inside the Lab: Why We Perform the Double Shear Test on Ringlock Scaffolding Rosettes

At FormScaffold, we believe that safety is not just a promise—it is a measurable science.

For construction companies and project managers, the reliability of the Ringlock Scaffolding System hinges on one critical component: the Rosette Node. This small connector bears the weight of the entire structure, workers, and materials.

Today, we are sharing exclusive footage from our R&D Quality Control Lab to demonstrate the Double Shear Strength Test of our scaffolding connection plates.

What is a Double Shear Test?

The Double Shear Test simulates the vertical forces applied to the ledger-to-rosette connection in real-world scenarios. By applying downward pressure on both sides of the rosette simultaneously, we measure:

1. Slip Resistance: At what force does the connection start to deform?

2. Ultimate Failure Load: What is the maximum weight the joint can hold before breaking?

Why This Matters for Your Project

Many suppliers claim “high quality,” but few provide the data to back it up. Our testing protocol ensures compliance with EN 12811 (European Standard) and ANSI/SSFI (American Standard).

The Results: In this specific test, our Ringlock Rosette demonstrated a failure load significantly higher than the industry requirement. This means:

• Higher Safety Factor: Your workers are safer, even under heavy loads.

• Structural Integrity: Reduced risk of scaffolding collapse or deformation.

• Durability: Our high-precision welding and Q355 steel withstand rigorous use.
