The core advantage of our GLL Construction Ringlock Scaffold Zinc Plate comes from the galvanized steel plate substrate it uses. Through the hot-dip galvanizing process, a dense zinc-iron alloy layer is formed on the surface of the steel plate, giving the product the following characteristics:
Super corrosion resistance: In the salt spray test, GLL Ringlock Scaffold corrosion rate of the galvanized layer is only 1/20 of that of ordinary carbon steel, which can resist coastal high salt spray, industrial acid and alkali environment and humid climate erosion.
Optimized Strength-Toughness Synergy: GLL employs Q345 low-alloy high-strength steel, achieving a yield strength of 345MPa and tensile strength exceeding 470MPa while preserving an elongation rate greater than 22%. This dual-performance balance ensures exceptional structural integrity under static loads and robust resistance to dynamic impacts, enabling reliable performance across demanding engineering applications.
Environmentally friendly surface treatment: The galvanizing process complies with the EU RoHS standard, there is no heavy metal pollution in the production process, and the zinc layer can be 100% recycled, which is in line with the global green building trend.
The revolutionary design of our GLL Construction Ringlock Scaffold Zinc Plate is concentrated in the ring lock connection system:
Three-dimensional connection technology: Each vertical pole is equipped with an eight-way rose joint every 0.5 meters, which can simultaneously connect the crossbar, diagonal brace and working platform to achieve the rapid construction of the spatial grid structure. Actual measurements show that the average daily construction volume of a 4-person team can reach 150 cubic meters, which is 40% more efficient than the bowl-lock scaffold.
Self-locking wedge pin: Gravity self-locking design is adopted, and the pin automatically bites after insertion, and the anti-slip force reaches 8kN, far exceeding the OSHA standard requirements. With the double insurance anti-drop device, the risk of accidental loosening is reduced to less than 0.03%.
Modular compatible design: The standard parts have a universal matching rate of 98%, which can be used interchangeably with the mainstream brand ring lock system to reduce the customer’s spare parts inventory cost.
GLL scaffolding has passed a number of extreme tests to verify its excellent performance:
Load test: Under the condition of 4.0m span, the deformation is only 12mm when the uniform load reaches 8.5kN/m², which is better than the EN 12810 standard requirements.
Fatigue test: After 5000 cycles of loading, the node stiffness retention rate is still 92%, meeting the long-term construction needs of large public buildings.
Fireproof performance: The galvanized layer still maintains structural integrity at a high temperature of 650℃, providing key safety guarantees for fire evacuation in high-rise buildings.
