Galvanized hollow section (GHS) is a high-strength, steel tubular product featuring a zinc-coated surface that protects against corrosion. It is widely used in construction and industrial applications where durability, structural integrity, and resistance to environmental damage are required.Galvanized hollow section is high selling product for Hebei K-Steel Pipe Industry
Key Characteristics & Benefits
Corrosion Resistance: The zinc coating (via hot-dip or pre-galvanization) acts as a sacrificial barrier against rust and moisture, offering a long service life, often up to 30–50 years.
High Strength-to-Weight Ratio: The hollow design provides excellent load-bearing capacity while being lighter than solid steel profiles.
Versatility & Aesthetics: Available in various shapes and sizes with a smooth, clean aesthetic suitable for visible architectural applications.
Easy Fabrication: They can be cut, welded, and bolted to create complex frameworks.
Types of Galvanized Hollow Sections
SHS (Square Hollow Section): Used for columns, frames, and fencing.
RHS (Rectangular Hollow Section): Preferred for beams, heavy frames, and structural supports.
CHS (Circular Hollow Section): Often used for railing and piping.
Hot-Dip Galvanized: Immersed in molten zinc after forming, creating a thick, highly durable coating suitable for harsh environments.
Pre-Galvanized: Formed from pre-coated steel strips, providing a uniform, smooth surface ideal for indoor/light-duty applications.
Galvanized hollow sections are used extensively across several sectors:
Structural & Construction: Building frames, roof supports, purlins, and truss systems.
• Infrastructure: Guardrails, signboards, and bridge supports.
• Industrial & Agricultural: Conveyor supports, greenhouse frames, and farm fencing.
• General Fabrication: Machinery racks, storage racks, and safety railings.
