Engineered to international quality benchmarks, including EN 12810, EN 12811, and ISO 9001 certifications.
In the modern global construction paradigm, safety, structural efficiency, and speed of assembly have transitioned from project targets to non-negotiable operational requirements. As high-rise, commercial, infrastructure, and heavy industrial sectors expand, legacy scaffolding configurations are rapidly being replaced by modular systems. Foremost among these technologies is the Ringlock Scaffolding System. Characterized by its unique rosette design, wedge connections, and structural versatility, Ringlock represents a critical milestone in load-bearing efficiency and worker safety.
Zhuozhan Group operates as a diversified and innovative enterprise that seamlessly integrates scientific research, manufacturing, and international trade sales. With a robust portfolio of specialized subsidiaries, including Laoting Zhuozhan International Trade Co., Ltd. and Hebei Shuangyang Metal Structure Co., Ltd., Zhuozhan Group has established itself as an authoritative global player in structural engineering solutions.
Founded in 2014, Hebei Shuangyang Metal Structure Co., Ltd. is the manufacturing backbone of the group. Occupying a total area of 13,132.68 square meters, with a built-up factory space of 7,124.58 square meters, the facility employs over 500 highly skilled personnel operating more than 150 sets of advanced metal processing machinery. Through dedicated research and development, Shuangyang has secured 15 national patents, reflecting its technical capability and focus on continuous design improvement.
The global construction market is experiencing a significant shift away from legacy frame and cuplock systems to Ringlock configurations. This transition is motivated by rigorous regional safety standards (such as OSHA in North America and EN regulations across Europe). The structural design of Ringlock—consisting of vertical standards with fixed circular rings (rosettes) positioned every 500mm, alongside horizontal ledgers and diagonal braces—allows for rapid, secure locking. By eliminating loose fittings and minimizing the need for manual leveling tools, users can expect to lower construction risk while improving bottom-line efficiency.
China's dominance in structural steel fabrication is supported by integrated supply chains, automated production lines, and high-quality raw materials. As a direct source factory, Hebei Shuangyang Metal Structure Co., Ltd. features an annual output capacity of 300,000 tons of steel pipes, 1,000,000 tons of high-grade scaffolding systems, and 400,000 tons of adjustable steel supports. This massive capacity helps stabilize lead times and protect global supply contracts from market volatility.
Our source factory features an expanded footprint of 40,000 square meters with an annual industrial output exceeding 200,000 tons of specialized components, ensuring consistent volume delivery for large-scale operations.
Our manufacturing base is strategically located near three of China's most active maritime hubs: Jingtang Port, Tianjin Port, and Caofeidian Port. This geographical placement reduces inland transport costs and shortens sea transit times.
Tested under rigorous conditions, our systems carry formal European compliance stamps including EN 12810/12811 and ISO 9001 certification, confirming their suitability for highly regulated worksites.
The primary advantage of Zhuozhan Group's Ringlock system lies in the use of high-strength structural steel combined with precise fabrication standards. Below are the core mechanical and physical performance advantages that set our systems apart from standard scaffolding on the market:
Manufactured from premium Q355B structural steel, a single standard standard can support up to 10 tons of vertical load. This is approximately 1.5 times the load-bearing capacity of typical carbon steel (Q235) systems, which reduces the total number of components required for complex structural shoring designs.
The pre-spaced modular connections permit assembly rates of 150 to 300 square meters per worker, per day. This speed is 3 to 5 times faster than traditional tube-and-clamp setups, lowering labor costs and helping to keep projects on schedule.
Every component undergoes a comprehensive Hot-Dip Galvanizing (HDG) treatment. With a zinc coating thickness designed for challenging climates, our scaffolding offers an average service life of over 10 years, reaching 15 to 20 years under standard storage and maintenance conditions.
Because Q355B steel offers superior load-bearing capacity, our designs can reduce overall scaffolding weight by 1/2 to 1/3 compared to traditional setups for the same load. This weight reduction simplifies shipping, handling, and storage logistics.
By using automated punching and robotic welding stations, our production lines maintain a tight dimensional tolerance of ±1mm across all standards, ledgers, and braces. This precision ensures seamless compatibility and structural alignment on the worksite.
In accordance with ISO 9001 and environmental regulations, the production processes for both Vertical Standards (Rods) and Horizontal Ledgers (Rods) are monitored to maintain consistency and trace material quality.
High-grade Q355B steel pipes are cut to design lengths using automatic sawing machines.
Noise (N) & Solid Waste (S) MonitoredPrecision hydraulic machines punch structural holes and slot spacing targets on the pipe walls.
Solid Waste (S) RecycledMulti-point robotic welding systems attach the black steel rosettes and sleeve joints to the standards.
Fume Filtration (G) & Solid Waste (S) MonitoredThe welded standard undergoes acid pickling and is hot-dip galvanized in accordance with BS EN ISO 1461 standards.
Galvanized Coat InspectionStandards are measured for dimensional tolerance, alignment, and thread quality before packaging.
Raw steel tubes are cut to length for ledgers based on the selected grid configuration.
Noise Control ActiveThe tube ends are flattened and punched to receive the cast-steel ledger ends.
Steel Scraps RecycledLedger ends are automatically aligned and welded to the tube bodies, forming a strong joint.
Gas & Dust Filtration ActiveLedgers are hot-dip galvanized to ensure complete protection against corrosion inside and out.
Wedge pins are riveted into the casting head assemblies to complete the self-locking system.
Mechanical Testing PerformedFinished ledgers are bundled, labeled with batch details, and stored for delivery.

Purchasing structural scaffolding equipment requires careful technical evaluation. Below are answers to the most common questions asked by procurement departments and engineering leads:
Q355B is a low-alloy, high-strength structural steel with a yield strength of 355 MPa. In comparison, Q235 carbon steel has a yield strength of 235 MPa. By using Q355B, our Ringlock scaffolding achieves a single-column load capacity of up to 10 tons. This high capacity allows engineers to design structures with wider spacing, reducing the total amount of scaffolding required for a project by up to 30% compared to standard systems.
Our components are treated with hot-dip galvanizing, which creates a thick, durable zinc-iron alloy coating over the steel. This treatment provides excellent protection against humidity, rain, and corrosive industrial environments. As a result, our scaffolding lasts an average of 10 to 20 years, compared to just 2 to 5 years for painted or electro-galvanized alternatives.
Zhuozhan scaffolding is manufactured to meet EN 12810 and EN 12811 European standards. These regulations govern temporary work equipment, structural design, and load capacity. Our production facility is certified under the ISO 9001 quality management system, ensuring batch traceability and material testing for all shipments.
