As Southeast Asia's largest economy, Indonesia is undergoing an unprecedented infrastructure boom. Mega-projects such as the construction of the new capital city IKN Nusantara in East Kalimantan, the Trans-Sumatra Toll Road, extensive mineral downstreaming smelter complexes in Morowali and Halmahera, and key energy refineries operated by Pertamina require highly robust, temporary access and support solutions.
Historically, local engineering projects relied on traditional frame structures, steel pipes with couplers, or even bamboo. However, the Indonesian Ministry of Manpower (Kementerian Ketenagakerjaan) and the Ministry of PUPR have strict enforcement strategies regarding on-site health and safety (K3 guidelines). Standardized ringlock scaffolding systems are rapidly replacing old solutions because of their unparalleled stability, resistance to environmental loading, and quick structural self-locking capabilities.
Industrial scaffolding used in wet tropical zones must meet extreme anti-corrosion benchmarks. The extreme relative humidity (often exceeding 80%) along with coastal salt sprays around Java, Sumatra, and Kalimantan creates a severe corrosivity environment (C4 to C5 categories). This requires structural steel components to have heavy hot-dip galvanization to avoid premature oxidation and sudden structural failure.
A unified manufacturing and global trading powerhouse leading the advanced metal structure industry.
Zhuozhan Group stands as an innovative, highly integrated industrial enterprise combining scientific research, high-precision manufacturing, and reliable worldwide logistics. Our operations are driven by two main subsidiaries: Laoting Zhuozhan International Trade Co., Ltd. (global trade facilitation and regional supply chains) and Hebei Shuangyang Metal Structure Co., Ltd. (manufacturing base).
Our manufacturing subsidiary, Hebei Shuangyang Metal Structure Co., Ltd., was established in 2014. Spanning a modern manufacturing footprint of 13,132.68 square meters (with 7,124.58 square meters of specialized covered workshops), it houses more than 150 advanced production machines. Operating with a workforce of 500+ professionals and a dedicated engineering design team, we utilize 15 national patents to manufacture superior quality scaffolding systems certified to EN 12810/12811 and ISO 9001 quality controls.
We work closely with major international developers and Chinese state-owned construction contractors (e.g., China Construction Eighth Engineering Division, China Construction Fourth Engineering Division) on complex infrastructure and energy projects throughout Southeast Asia.

Why procurement teams from Jakarta, Surabaya, and Balikpapan source directly from our automated Chinese facility.
Our standards are built from heavy-duty Q355B low-alloy steel. Offering a yield strength of ≥355 MPa, it delivers 1.5 times the structural load capacity of traditional Q235 frame tubes. We can reach a vertical safe load rating of up to 10 tons per standard leg.
All structural parts undergo hot-dip galvanization (HDG) strictly in line with EN ISO 1461 standards. The zinc coating thickness averages over 60-80 microns. This ensures a service life of 15 to 20 years, even when exposed to high humidity and salty marine environments.
The rosettes are welded to standards using high-precision, automatic robotic welding lines. This keeps structural dimensional errors within ±1mm. Every weld undergoes testing to ensure the rosettes resist impact and prevent tear-offs under load.
Our plant is strategically positioned in Tangshan, Hebei, near Jingtang Port, Caofeidian Port, and Tianjin Port. This offers flexible sea transport routes to key Indonesian ports like Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), and Balikpapan.
Our dedicated design team of over 20 engineers uses AutoCAD and specialized software to create custom shoring layouts. We calculate exact loads, optimize component configurations, and design specialized systems to match challenging layouts.
We assign project managers to handle the entire export process, from production tracking to custom clearance documents. They offer technical answers within 24 hours to match the fast pace of major global infrastructure projects.

A step-by-step overview of how Hebei Shuangyang manufactures high-durability vertical standards and horizontal ledgers.
Steel tubes are cut to exact lengths. Generates localized noise (N) and solid scrap (S).
Rosette node positions are punched onto the standard. Generates noise (N) and scrap (S).
Rosette nodes are welded using robot lines. Generates controlled gas (G) and noise (N).
Components are dipped in molten zinc at 450°C. Protects against harsh tropical climates.
Strict tolerances are checked, and parts are packaged for shipment to Indonesia.
Pipes are cut to size using CNC machines. Generates noise (N) and steel waste (S).
Both ledger ends are pressed to fit wedge connectors. Generates mechanical noise (N).
Cast steel ledger ends are welded to standard tubes using robotic welding lines.
Cleaned components are hot-dip galvanized to ensure optimal anti-corrosion properties.
Wedge pins are riveted into ledger ends. Prepares units for structural installation.
Tailored temporary access and heavy shoring systems designed for local terrain and safety demands.
Refinery expansions (such as Pertamina's Balikpapan RDMP and Cilacap operations) require spark-free, highly stable access platforms. Our EN 12811 certified ringlock systems provide safe, multi-level platforms around tall distillation columns and process boilers.
Heavy mineral operations in Morowali, Weda Bay, and Southeast Sulawesi rely on heavy shoring systems. Our ringlock platforms support high-temperature furnaces, ore conveyors, and storage silos during construction and maintenance.
Infrastructure projects like the Jakarta LRT/MRT and Sumatra toll bridges require strong support. Our ODM Multiprop systems and heavy-duty ringlock towers support wet concrete loads of up to 10 tons per column, preventing frame deflection.
Our scaffolding systems are engineered, tested, and certified to meet global building codes.
