Wholesale Medium Wall Rectangular Tube from China Suppliers - Yuantai Derun Factory Quality Since 2002
Building Unshakeable Foundations with Premium Medium Wall Rectangular Tube
The backbone of modern mega-structures requires more than ordinary steel; it demands unwavering strength, precision, and reliability. Our Medium Wall Rectangular Tubes are engineered to be that definitive core, offering unmatched load-bearing capacity and structural integrity for the world's most ambitious projects. Designed for applications where failure is not an option, these tubes combine a robust, large square profile with significant wall thickness to create a structural component that excels in both compression and torsion.
From the skeletal frames of skyscrapers to the critical supports of industrial complexes, this product is the material of choice for engineers and architects who prioritize safety, durability, and long-term value. We deliver more than just tubing; we provide the confidence that comes with a product built to endure decades of service under extreme demands.
Engineered for Maximum Load-Bearing & Durability
Our manufacturing philosophy centers on creating a product that performs consistently under stress. The heavy-wall construction is key to its superior performance.
The large square geometry and thick walls provide an optimal balance, offering immense strength without unnecessary weight, leading to more efficient and often more economical structural designs.
The inherent stability of the square shape, amplified by the heavy wall, provides outstanding resistance to buckling and deformation under heavy axial loads, making it ideal for columns, piers, and vertical supports.
Compared to other profiles, the closed shape offers excellent torsional (twisting) resistance, crucial for beams, trusses, and framework subject to dynamic or uneven loads.
Manufactured from fine-grained, certified steel, our tubes exhibit excellent resistance to structural fatigue, ensuring longevity in applications subject to vibration, wind loads, or recurring stress cycles.
Why Our Medium Wall Rectangular Tube is the Superior Choice
Choosing the right structural material impacts the entire lifecycle cost and safety of a project. Here's what sets our product apart:
-
Uncompromising Material Integrity
We source prime steel slabs from top-tier mills globally. Every batch is certified and traceable, with chemical composition strictly controlled to meet or exceed the required mechanical properties for structural applications.
-
Precision Advanced Manufacturing
Utilizing state-of-the-art ERW (Electric Resistance Welding) or JCOE forming processes, we ensure a perfect, high-integrity weld seam and exceptional dimensional accuracy across the entire length of the tube. This results in consistent wall thickness and true 90-degree angles.
-
Rigorous, Multi-Stage Quality Assurance
Our commitment is validated through a battery of tests. Each production lot undergoes dimensional checks, visual inspection, ultrasonic testing for weld integrity, and mechanical testing (tensile, yield strength). Certifications for ASTM, EN, JIS, and other international standards are standard.
-
Technical & Customization Partnership
Our engineering support team works with you to select the optimal grade, wall thickness, and finish. We offer custom lengths, end treatments, and protective coatings (galvanizing, painting, weathering steel) tailored to specific environmental challenges like coastal salinity or industrial corrosion.

Our Medium Wall Rectangular Tubes are available in common square sizes ranging from 300mm x 300mm up to 1000mm x 1000mm, with wall thicknesses from 8mm up to 60mm. Standard lengths reach up to 18 meters, and custom lengths can be arranged to meet specific project requirements.
Our tubes are produced to a wide range of international standards, including ASTM A500 Grade B/C, ASTM A1085, EN 10210 S355J2H and S460NH, JIS G3466, and GB/T 6728 Q355B. Each batch is certified and fully traceable to ensure compliance with your project's structural specifications.
We utilize advanced ERW (Electric Resistance Welding) and JCOE forming processes. These methods ensure a high-integrity weld seam, exceptional dimensional accuracy, consistent wall thickness, and true 90-degree corner angles throughout the entire length of the tube.
We offer mill finish (black), pre-primed, and hot-dip galvanized finishes (conforming to EN ISO 1461). Custom protective coatings such as painting and weathering steel treatments are also available, particularly suited for challenging environments such as coastal salinity or heavy industrial corrosion exposure.
Every production lot undergoes a rigorous multi-stage quality assurance process including dimensional checks, visual inspection, ultrasonic testing for weld integrity, and full mechanical testing covering tensile and yield strength. Certifications are issued in accordance with ASTM, EN, JIS, and other applicable international standards.
These tubes are widely used across commercial and high-rise construction (load-bearing columns, transfer beams), industrial facilities (crane runways, warehouse mezzanines), infrastructure and energy projects (bridges, power transmission towers, offshore platforms), and large-scale public projects such as stadiums, airports, and exhibition centers.
