Steel box section, commonly known as hollow structural steel tubing, is a type of steel product manufactured with a hollow cross-sectional shape. Thanks to its closed-section design and the inherent strength of steel, steel box sections offer excellent structural integrity, high load-bearing capacity, and outstanding durability under various working conditions.
Combining strength, versatility, and ease of fabrication, steel box sections have become one of the most widely used materials in construction, infrastructure, transportation, and manufacturing industries.
Classification by Shape
Square Hollow Section – SHS
Square steel tubes feature equal side dimensions and are widely used in structural applications requiring balanced strength and stability.
Rectangular Hollow Section – RHS
Rectangular steel tubes provide excellent load distribution and are particularly suitable for frameworks, vehicle structures, and architectural applications.
Phân loại theo bề mặt
Black Steel Box Section
Manufactured without protective zinc coating, black steel box sections are commonly used in indoor applications or where additional surface treatment will be applied.
Galvanized Steel Box Section
Coated with a protective zinc layer to improve corrosion resistance, galvanized steel box sections are ideal for outdoor and humid environments.
Key Characteristics:
✨ High Strength and Structural Stability
The hollow-section design provides excellent strength-to-weight ratio while maintaining high resistance to bending, compression, and torsion.
✨ Excellent Load-Bearing Capacity
Steel box sections can withstand substantial mechanical loads, making them suitable for structural and industrial applications.
✨ Good Fabrication Performance
Easy to cut, weld, drill, and assemble, allowing efficient manufacturing and installation.
✨ Versatile and Cost-Effective
Available in a wide range of sizes and thicknesses to meet diverse engineering requirements while maintaining economical project costs.
✨ Corrosion Resistance (Galvanized Types)
Galvanized steel box sections provide enhanced protection against rust and environmental exposure, extending service life in outdoor applications.
