Product Introduction

Q460 RHS Tube Description

Q460 Carbon Steel Rectangular Pipe is used in shipbuilding, bridge erection, power station equipment, medium/high-pressure boilers, high-pressure containers, motor vehicles, lifting machinery, mining machinery, as well as other large-scale welded structural components and other industrial fields.

Features
High strength characteristics: "Q" in the name stands for yield strength, and "460" means the minimum yield strength is 460MPa, which is about 96% higher than the strength of ordinary carbon structural steel (such as Q235).
Excellent toughness: It still maintains an impact energy of more than 27J at a low temperature of -40℃, which is suitable for projects in severe cold areas.
Good welding performance: Carbon equivalent (Ceq) ≤ 0.42%, low cold crack sensitivity, and high welding reliability.
Strong weather resistance: Surface treatment (such as hot-dip galvanizing) can significantly improve corrosion resistance and extend service life.

Advantages

‌Outstanding bearing capacity‌: High yield strength makes the cross-section size smaller under the same load, reduces the deadweight of the structure (such as a 23% weight reduction in a certain project), and reduces the foundation cost by about 15%.
‌Significant economic efficiency‌: Reduced material consumption, reduced transportation and installation costs, and high overall cost performance‌.
‌Strong resistance to complex stress‌: The square/rectangular cross-section design provides excellent torsion and bending resistance, and is suitable for heavy load and dynamic load environments‌.
‌Convenient construction‌: Standardized modular design simplifies on-site installation and improves engineering efficiency‌.
