Engineered to conform with strict international structural standards and heavy industrial requirements.
An authoritative overview of our diversified engineering research, global footprint, and manufacturing capabilities.
In the globalized industrial landscape, modern logistics facilities, heavy-duty workshops, and commercial storage hubs rely heavily on the integrity of pre-engineered building (PEB) solutions. Zhuozhan Group stands at the forefront of this industrial sector, operating as a highly diversified and innovative enterprise that seamlessly integrates scientific research, design engineering, manufacturing, and international trade operations. Backed by key corporate subsidiaries including Laoting Zhuozhan International Trade Co., Ltd. and Hebei Shuangyang Metal Structure Co., Ltd., the group provides advanced, cost-effective structural systems to engineering contractors and enterprise developers worldwide.
Our primary manufacturing node, Hebei Shuangyang Metal Structure Co., Ltd. (established in 2014), operates a massive production compound. Spanning an expansive area of 13,132.68 square meters, featuring specialized production facilities covering 7,124.58 square meters, the company relies on over 500 highly trained technicians and steel fabrication experts. Driven by advanced engineering standards, Hebei Shuangyang operates more than 150 sets of heavy-duty machinery, robotic welding interfaces, and precise dimensional milling tools. This capacity guarantees a stable supply of key materials required for structural warehouse frameworks, modern industrial support scaffolding, structural pipe configurations, and heavy shoring systems.
Detailed mechanical parameters, chemical composition options, and compliance standards for modern steel structures.
By employing premium structural steel (Q355B/Q235), the single-point vertical load-bearing capacity of our structural frame components reaches up to 10 tons—which is 1.5 times stronger than conventional carbon steel alternatives. This allows developers to reduce total column weight while maintaining structural safety.
We implement a strict hot-dip galvanization process that meets international ISO 1461 specifications. Our structural steel elements achieve a zinc coating thickness that ensures an average operational lifespan of 15 to 20 years, even when exposed to harsh maritime or industrial environments.
Using computerized CNC machining centers and robotic cutting setups, our manufacturing lines enforce structural component tolerances within a strict ±1mm range. This degree of accuracy prevents installation discrepancies, structural misalignments, and on-site welding modifications.
| Steel Grade Designation | Yield Strength (Fy - Min) | Tensile Strength (Fu) | Standard Equivalents | Primary Industrial Applications |
|---|---|---|---|---|
| Q235B | 235 MPa | 370 - 500 MPa | ASTM A36 / BS EN S235JR | Secondary structural members, bracing configurations, platforms, and scaffold components. |
| Q355B (formerly Q345B) | 355 MPa | 470 - 630 MPa | ASTM A572 Gr 50 / BS EN S355JR | Primary structural portals, load-bearing portal columns, main warehouse rafters, and heavy crane runways. |
| Q420B | 420 MPa | 520 - 680 MPa | ASTM A572 Gr 60 / BS EN S420JR | Super high-span structural configurations, heavy machinery support grids, and specialized offshore modules. |
Why leading global corporations source their pre-engineered structural frames from Hebei Shuangyang.
Our strategic manufacturing location in Hebei provides direct, immediate access to three major shipping hubs: Jingtang Port, Caofeidian Port, and Tianjin Port. This logistical configuration minimizes domestic overland freight times, lowers port handling fees, and offers highly competitive international sea shipping rates.
Our manufacturing and assembly systems operate under strict compliance with internationally recognized certifications, including EN 12810/12811 for scaffolding structures and ISO 9001 quality management systems. Our structural steel members undergo thorough magnetic particle, ultrasonic, and load-bearing testing.
Our scaling capabilities are backed by an annual production volume of 300,000 tons of structural steel pipes, 1,000,000 tons of system scaffolding, and 400,000 tons of adjustable steel shoring props. This scale allows us to fulfill large-scale orders without delaying concurrent project phases.
Transparent tracing of vertical and horizontal structural framing production steps under ISO environmental compliance guidelines.

Pre-engineered steel warehouse frames applied across diverse industrial zones and heavy infrastructural environments.
Our heavy-duty steel buildings are designed to accommodate large bridge cranes (5-ton to 50-ton capacities), multi-tier mezzanine decks, and complex overhead piping layouts. A key example includes our steel framework supply for the Bosch NEV R&D and Workshop Expansion project in Suzhou (2024–2025).
Large clear-span configurations (up to 60 meters without internal support columns) provide optimal clearance for distribution equipment and automatic storage systems. We also supply custom finishing machinery, such as laser screeds, for projects like high-load airport runways.
Our custom-engineered steel structures for barns offer tailored solutions with steel members ranging from 6mm to 32mm in thickness. These structures resist snow and wind loads while protecting livestock, large machinery, and feed inventories.

Procuring raw pre-engineered steel frames requires reliable global supply chains. Through Laoting Zhuozhan International Trade Co., Ltd., we offer direct support to global clients, handling local import customs, arranging shipping documents, and managing final delivery details. Our distribution network serves projects in the United States, Canada, China, Hong Kong SAR, Malaysia, Thailand, and Indonesia, helping developers secure the materials they need to keep their projects on schedule.
By coordinating the production of structural warehouse frames with temporary support systems (scaffolding and shoring), we help clients purchase complete, compatible structural packages directly from a single manufacturer.
Our in-house design team collaborates with engineering teams to modify structural drawings, adjust steel thickness configurations (from 6mm up to 32mm), and select optimal paint and hot-dip galvanized coatings to meet local regulatory codes.
