Precision engineered scaffolding systems, formwork accessories, and safety props for large scale industrial and civil engineering projects.
In modern industrial and civil construction, safety, modular versatility, and load-bearing efficiency dictate project profitability. The Scaffolding Ring Lock System has emerged as the definitive standard for modular shoring and scaffolding worldwide. Featuring a rosette node configuration that allows up to eight connections at multiple geometric angles, the ringlock mechanism distributes loads along axial vectors with exceptional rigidity. Unlike conventional tube-and-clamp setups or outdated cuplock designs, the wedge-lock connection minimizes structural play and virtually eliminates connection slippage under massive dynamic load sequences.
As engineering demands scale alongside high-rise developments, offshore marine infrastructure, and heavy industrial facilities, global procurement officers are prioritizing manufacturers who offer comprehensive OEM and ODM capabilities. Chinese manufacturers, supported by advanced automated metal fabrication hubs and regional raw material clusters, now lead the international market in delivering ringlock systems that comply with rigid safety guidelines, including EN 12810/12811 and OSHA standards.

Founded in 2014, Hebei Shuangyang Metal Structure Co., Ltd. is a pivotal subsidiary that has rapidly advanced to the forefront of the industry. The company operates within a total area of 13,132.68 square meters, featuring a modern construction area of 7,124.58 square meters. Equipped with over 150 sets of advanced machinery—including fully automated robotic welding arms, high-precision punching presses, and digital dimensional inspection arrays—Shuangyang processes raw carbon steel into highly precise structural assets. The company's annual output features 300,000 tons of steel pipes, 1,000,000 tons of high-grade scaffolding, and 400,000 tons of adjustable steel supports, making it a critical supply chain partner to both domestic and international markets.
Our ring lock scaffolding systems conform to rigorous international benchmarks, including European EN 12810/12811, American OSHA standards, and ISO 9001 quality management guidelines. By employing high-strength Q355B and Q235 carbon steel treated via hot-dip galvanization (HDG), we ensure extreme corrosion resistance and structural lifespans exceeding 15 to 20 years in harsh outdoor marine environments.
Supported by our portfolio of 15 national utility patents, our dedicated engineering team operates continuously to optimize the structural weight-to-performance ratio of our ringlock systems. Through finite element analysis (FEA), we design custom configurations that maximize safety while reducing overall tonnage requirements for multi-story shoring and suspended work zones.
Laoting Zhuozhan International Trade division facilitates seamless logistics integration, custom clearance, and multi-port shipping setups. Operating close to three major deep-water ports (Jingtang, Tianjin, and Caofeidian), we guarantee low lead times, competitive freight costs, and continuous supply lines to projects in North America, Europe, the Middle East, and Asia.
How localized raw material ecosystems and automated technology drive cost efficiency and quality control.
Operating a dedicated 40,000 square meter factory footprint with 14 automated manufacturing lines, Zhuozhan maintains an annual output capacity exceeding 1,000,000 tons of scaffolding structures. This scale allows us to buffer sudden supply chain spikes and fulfill large-scale EPC contractor requirements without scheduling bottlenecks.
Our production facilities are strategically located near Jingtang Port, Tianjin Port, and Caofeidian Port. This structural proximity to major international shipping routes reduces domestic transit costs, mitigates weather-related inland logistics delays, and ensures that containerized shipments reach regional transshipment ports efficiently.
We work closely with major state-owned and central enterprises, such as the China Construction Eighth Engineering Division and China Construction Fourth Engineering Division. These demanding relationships serve as proof of our system reliability and structural compliance across massive domestic infrastructure programs.
Detailed engineering characteristics that outperform traditional cup-lock and frame scaffolding setups.
Fabricated using Q355B high-strength structural carbon steel, our vertical standards support an ultimate individual load-bearing capacity of up to 10 tons. This is 1.5 times the structural rating of standard Q235 scaffold tubes, enabling engineers to design shoring towers with fewer vertical uprights.
The self-locking wedge connection streamlines operations. A single scaffolding technician can erect 150 to 300 square meters of ringlock structure per day—a performance level 3 to 5 times faster than traditional scaffold tube couplings. This directly translates to significant reductions in on-site labor budgets.
With a rosette design that supports up to 8 independent connections at precise geometric angles, our ringlock system adapts to curved industrial boilers, spherical gas tanks, complex aircraft hulls, shipbuilding scaffolds, and high-rise irregular facades with minimal component customization.
Under equivalent structural load-bearing parameters, the ringlock scaffolding system reduces total raw steel consumption by up to 50% compared to tube-and-clamp setups. The overall deadweight of the structure is reduced by 1/2 to 1/3, decreasing crane cycles and shipping costs.
By employing a heavy-duty hot-dip galvanization (HDG) coating process, our components maintain a protective zinc alloy layer averaging over 80 microns. This yields an operational lifespan of 15 to 20 years under normal handling, and over 10 years in corrosive environments.
Utilizing high-precision automated manufacturing equipment, the dimensional variance across our standards, ledgers, and diagonal braces is held within a strict ±1mm range. This tight calibration ensures smooth lockup during assembly and prevents structural wobble.
How raw metal tubes are processed into certified structural components under environmental and quality assurance protocols.
The vertical standard holds the axial weight of the entire scaffold tower. Precise welding of the rosette plate is critical to prevent structural eccentricity.
Raw steel pipes are cut to exact lengths. Continuous monitoring controls physical noise (N) and solid scrap steel waste (S).
Advanced hydraulic presses punch hole locations for locking pins. Controlled processing maintains dimensional accuracy.
Automated CO2 gas shielded welding aligns and welds the steel pipe with the structural disc black parts. Dust extraction systems handle emissions.
Welded components are transferred to specialized hot-dip galvanizing lines, forming a robust zinc-iron alloy coating.
Galvanized standards are verified for dimensional accuracy, weight tolerances, and weld penetration before structural certification packaging.
The horizontal ledger acts as the tension-compression beam stabilizing the vertical columns and supporting the work decks.
Raw steel pipes are cut to size using automated circular cold saws to ensure clean edges.
Tube ends are profile-punched or pressed to receive cast steel ledger endings.
The end connections are welded to the tube using specialized robotic positioning arms for uniform strength.
Ledgers are hot-dip galvanized to protect all weld seams and internal surfaces against moisture ingress.
Cast steel insert wedges are riveted to the ledger ends, completing the self-locking system for direct site deployment.
How modular ringlock systems meet complex engineering challenges across diverse operating sectors.
For large highway viaducts and complex concrete bridge shoring, our ringlock scaffolding provides robust support. Incorporating Q355B standards allows for high load carrying capacities, which reduces the number of horizontal braces required and keeps construction paths clear.
Operating in coastal marine environments requires high resistance to salinity and ambient humidity. Zhuozhan's hot-dip galvanized coating stands up to sea spray, extending component service life and reducing maintenance requirements during offshore drilling and vessel maintenance.
Petrochemical refits require rapid erection and dismantling to keep outages brief. The wedge lock connection allows scaffolding crews to quickly assemble maintenance decks around boilers, pipes, and fractionating towers without loose couplings that can drop from heights.
Our structural assets undergo rigorous laboratory testing to verify load limits and performance consistency.
