Explore our high-performance structural steel and custom profiles, built to support complex engineering frameworks and scaffolding assemblies globally.
The demand for safe, lightweight, and versatile height access structures is rising rapidly across international commercial markets. Historically, traditional construction relied heavily on heavy carbon steel tube systems. However, modern safety mandates, structural efficiency standards, and localized labor costs have accelerated the structural shift toward Aluminium Scaffolding With Wheels. These dynamic mobile platforms, engineered primarily using high-tensile 6061-T6 or 6082-T6 structural aluminum alloys, offer an exceptional strength-to-weight ratio that optimizes load capabilities while dramatically reducing setup times.
In Western Europe and North America, strict occupational health and safety regulations (such as EN 1004 and OSHA Title 29) penalize heavy manual lifting. This has made mobile aluminum tower systems with safety wheels standard requirements for indoor maintenance, mechanical installations, and architectural restoration.
Although aluminum scaffolding presents a higher initial capital expenditure than galvanized steel structures, its long-term cost benefits are compelling. The lighter weight of aluminum lowers shipping costs, minimizes crew requirements, eliminates rust remediation expenses, and reduces set-up times by up to 50%.
Aluminum is 100% recyclable, aligning with modern green building standards like LEED and BREEAM. Leading manufacturers in China are adopting carbon-neutral extrusion lines and solar-powered manufacturing plants to align with global environmental mandates.
Established in 1998, Tianjin Minjie Steel Co., Ltd. has grown to become a cornerstone of structural steel and scaffolding manufacturing in North China. Spanning an expansive production footprint of more than 70,000 square meters, our facilities are located just 40 kilometers from XinGang Port (Tianjin), the largest seaport in Northern China. This strategic location facilitates rapid logistics and efficient global container shipping.
As a professional manufacturer and exporter, we integrate advanced metallurgic engineering with structural design. Our comprehensive manufacturing matrix comprises:
All our manufacturing processes align with international standards, including GB, ASTM, DIN, and JIS, and are governed by our rigorous ISO 9001 quality management certification.
Our focus on product safety and durability drives our technical innovation. We engineering-tested and received 3 proprietary patents for structural modifications: Groove Pipes, Shoulder Pipes, and Victaulic Pipes.
Our mobile scaffolding towers with wheels are engineered to comply with the European EN 1004 standard (Mobile access and working towers made of prefabricated elements). This standard governs wind load tolerances, guardrail height requirements, and safety deck loading capacities.
Utilizing specialized structural aluminum extrusions, the platform supports up to 272 kg/m² load ratings. Key connection nodes are reinforced with precision-welded gussets, and locking mechanisms feature double-action snap locks to prevent accidental disengagement.
Industrial-grade castor wheels are critical for mobile towers. Our scaffolding towers use 8-inch polyurethane-coated wheels with integrated screw jacks. These jacks offer up to 300mm of vertical adjustment, allowing leveling on uneven surfaces, while dual foot-pedal brakes lock both the wheel and rotation.
Our certifications ensure our manufacturing processes, environmental footprints, and health and safety management protocols align with international expectations.
Tianjin Minjie’s products are exported to markets worldwide. Through deep collaboration and high-quality fabrication services, we have built long-term relationships across Asia, Australia, and the Middle East.
In September 2019, our team visited structural clients in Singapore, solidifying project contracts for key commercial high-rise projects.
In 2019, a South Korean client visited our factory to collaborate on a new structural design, resulting in a successful manufacturing partnership.
An established Australian client visited us in November 2018 to review quality control systems for their construction distribution business.
In 2019, an Indian procurement group visited multiple factories and signed an ongoing container volume agreement with Tianjin Minjie.
A distributor from Lebanon visited our facility in June 2017 and ordered 1,000 tons of structural steel products.
First established at the Canton Fair in 2018, our partnership with a Saudi contractor has grown to support petrochemical facility maintenance.
Our company participates in the Canton Fair and international metal construction events annually. Meeting global procurement agents in person helps establish trust, and over 80% of our prospective clients choose to visit our manufacturing facilities in Tianjin for detailed quality evaluations.
We continue to expand our services by introducing automated welding lines and CNC laser tube processing to meet the specifications of commercial and industrial contracts.
Our mobile scaffolding systems are used across multiple sectors globally. We supply engineered access packages tailored to regional site conditions and compliance requirements.
In hangar facilities, our aluminum platforms provide lightweight access for aircraft maintenance. Non-marking polyurethane wheels protect floor coatings, while structural stabilizers ensure a rigid work area for maintenance technicians.
For curtain wall installations and building restoration, these mobile towers can be moved along building perimeters, reducing the need for heavy stationary scaffolding.
Combined with our hot-dip galvanized scaffolding tubes, our mobile platforms perform reliably in petrochemical environments. The specialized aluminum alloys offer resistance to industrial gases and marine corrosion.
As structural steel specialists, we supply key raw materials and finished products to construction markets worldwide.
Our structural materials are used in international civil infrastructure projects, power transmission towers, and industrial warehouses.
Safety standards in height-access systems are evolving toward lightweight materials and modular connectivity. As part of our product roadmap, Tianjin Minjie is investing in automated robotic welding cells to improve the reliability and strength of structural connections. We are also collaborating with metallurgical research centers to evaluate new high-ductility aluminum-magnesium-silicon alloys.
By shifting from manual to robotic pulse-MIG welding, we minimize heat-affected zones in structural tubes. This helps maintain the strength of the base metal near structural connections.
Developing modular ring-lock configurations in structural alloys allows users to customize scaffolding dimensions, adapting to varying work heights and site geometry.
We are researching castor wheels with integrated load sensors to monitor load distribution in real-time, helping prevent structural overloads during high-elevation work.

Aluminum mobile towers offer a high strength-to-weight ratio, weighing about 60% less than equivalent steel systems. This weight reduction simplifies logistics, lowers shipping costs, and reduces assembly times. Additionally, aluminum is naturally resistant to rust, extending its operational service life without requiring hot-dip galvanization.
EN 1004 sets standard rules for manufacturing mobile work towers, defining raw material standards, wind load tolerances, stabilization methods, and the minimum height of side guardrails (at least 1 meter above the work deck). Compliance with EN 1004 ensures the scaffolding is engineered to perform reliably under site conditions.
We recommend 8-inch polyurethane-on-nylon castor wheels with a steel core, rated for a static load capacity of 800 kg or more. The wheel should include dual pedal brakes to lock both rotation and rolling movement. Integrated leveling jacks are also essential to compensate for minor gradient variances on-site.
Direct contact between steel and aluminum can cause galvanic corrosion, particularly in damp or coastal environments. If steel accessories, such as outriggers or couplers, are used, they must be hot-dip galvanized or passivated. In addition, isolation liners should be used at connection points to prevent electrical contact between the metals.
We use visual inspections (VT) and liquid penetrant testing (PT) to verify structural welds, checking for surface porosity or cracks. For structural joints, we perform ultrasonic testing (UT) and load testing to confirm the weld throat thickness and penetration meet mechanical safety specifications.
