Zhuozhan Group stands as a diversified and innovative industrial leader, seamlessly blending state-of-the-art scientific research, advanced manufacturing, and seamless international sales operations. Through our specialized subsidiaries—including Laoting Zhuozhan International Trade Co., Ltd. and Hebei Shuangyang Metal Structure Co., Ltd.—we provide heavy industries, municipal constructors, and oil & gas facilities with certified modular support architectures.
Founded in 2014, Hebei Shuangyang Metal Structure Co., Ltd. serves as our primary manufacturing powerhouse. Occupying a sprawling 13,132.68 square meters (with 7,124.58 square meters of specialized covered workshops), our operations are supported by over 500 highly skilled welders, engineers, and supply chain specialists. Equipped with over 150 sets of automatic processing machinery, our current annual production benchmarks include 300,000 tons of high-grade steel pipes, 1 million tons of scaffolding, and 400,000 tons of heavy-duty adjustable steel supports.
Key metrics that validate our supply chain capabilities and manufacturing output.
Understanding the strict technical definitions of EN 12810 and EN 12811 for temporary access equipment.
Specifies structural design requirements, performance criteria, and verification methods for modular system scaffolds. Covers key parameters such as loading classes, protective guardrails, and connection node integrity under high wind conditions.
Defines performance criteria and structural design requirements for temporary access equipment, including work platforms, access stairs, and shoring systems. Mandates standard loading parameters from Class 1 (0.75 kN/m²) up to Class 6 (6.00 kN/m²).
Constructed utilizing Q355B low-alloy, high-strength structural steel. Delivers a yield strength of ≥355 MPa and a tensile strength of up to 630 MPa, allowing for lighter configurations and structural material savings of up to 50% over conventional scaffolding.
At the core of the EN12810/12811 certified ringlock system is the modular rosette node interface. Unlike traditional scaffolding that utilizes loose couplings and friction-locked fittings, ringlock scaffolding secures vertical standards and horizontal ledgers using high-precision cast steel rosettes with up to 8 connection points. Once the wedge pin is driven into the rosette, it establishes a mathematically rigid, self-locking union.
This geometry generates exceptional structural resistance against dynamic horizontal forces. By utilizing vertical standards with a wall thickness of 3.25mm or 4.0mm, a single vertical tower assembled using our components can safely handle vertical axial loads of up to 10 metric tons per leg—1.5 times the capacity of conventional tube-and-clamp setups.
How global construction sites configure our scaffolding products to meet regional safety codes and specialized engineering demands.
Projects in Germany, France, and the UK demand rigorous certification adhering to local construction safety laws (such as the UK Work at Height Regulations). Scaffolding systems are configured using precise metric dimensions (e.g., bay widths of 0.73m, 1.09m, 1.40m, 2.57m, and 3.07m).
Key Configuration: Hot-Dip Galvanized standards with 3.2m / 3.25mm thickness, paired with integrated safety-lock steel decks.
Industrial sites in the United States and Canada must adhere to OSHA 1926 Subpart L and CSA S269 standards. Ledgers, diagonal braces, and accessories are adapted to both Imperial (e.g., 7-foot, 10-foot ledger spans) and metric system increments to interface with existing regional rental fleets.
Key Configuration: Heavy-duty spigot connections with safety pin retention locks, and robust screw jacks with cast iron collars.
Projects in UAE, Saudi Arabia, and Qatar focus heavily on high-rise building facades, civil flyovers, and major LNG infrastructure plants. Scaffolding must support extensive structural shoring and concrete formwork loads in high-temperature, coastal environments.
Key Configuration: Anti-corrosive Hot-Dip Galvanization (>80 microns thick) to resist coastal salt spray degradation.
