Built for Performance, Designed for Durability
The Black Square Rectangular Tube features a smooth, oxide-black finish that not only enhances aesthetic appeal but also provides an extra layer of protection against oxidation during storage and transport. Its precise right-angle corners and uniform cross-section make it ideal for welding, machining, and assembly in complex structural frameworks.
Whether used in high-rise buildings, bridge supports, machinery frames, or solar mounting systems, this tube delivers:
- High torsional rigidity
- Excellent weldability and formability
- Long service life with minimal maintenance
- Cost-effective logistics due to optimized weight-to-strength ratio
As a pioneer in structural steel innovation, YUANTAI DERUN continues to push boundaries with over 100 patents and cutting-edge R&D. Our Black Square Rectangular Tube isn't just a product—it's a promise of structural integrity, global compliance, and sustainable progress.
Manufacturing Process
Yuantai Derun's MS rectangular tubes are manufactured using reliable methods, including direct forming, round-to-square forming, and round-first-then-square processes.
To enhance performance and relieve internal stress, we offer heat treatment options such as normalizing, annealing, quenching, tempering, and corner heating.
