Core Advantages
1. Balance of strength and cost-effectiveness: Low Hot rolled carbon steel square tubes meet the strength requirements of most structures, with a price only one-third of stainless steel, suitable for bulk applications, and have significant cost advantages.
2. Excellent processing performance: Welded square tubes can be directly welded and cut, seamless square tubes can be cold drawn, heat treated and strengthened, suitable for various processing such as bending and drilling, meeting customized needs.
3. Regular cross-section and uniform force distribution: Square cross-section has better stability and torsional resistance than circular pipes when supported on a flat surface, saving material usage.
4. Flexible specifications and stable supply: From thin-walled decorative pipes to thick walled load-bearing pipes, they are all mass-produced with mature production processes and convenient procurement, which can quickly match project needs.
5. Surface treatment can be used to expand its applications: after galvanizing (zinc layer thickness ≥ 85 μ m), spraying (powder coating) and other treatments, the corrosion resistance is greatly improved, and it can be used in outdoor scenes.
